lijiachuan (Fri, 12 Jun 2020 00:47:18 GMT):
Hi All, I have one problem when I tried to response one credential request via await _credentialService.CreateCredentialAsync(context, model.CredentialID);, there is one error returned: ```Hyperledger.Aries.AriesFrameworkException: legalName mime type of not supported at Hyperledger.Aries.Utils.CredentialUtils.FormatCredentialValues(IEnumerable`1 credentialAttributes) ``` Then I found the reason, when I initially create the credential offer use below code: ``` var values = JsonConvert.DeserializeObject>(model.CredentialAttributes); values.Add(new CredentialPreviewAttribute("issuer", issuer.Owner.Name)); ``` The values passed from the form, their MimeType is null, but the issuer's MimeType is CredentialMimeTypes.ApplicationJsonMimeType, I am not sure where this default MimeType is assigned, but when I set the form values MimeType to CredentialMimeTypes.ApplicationJsonMimeType, this issue was resolved. So whether this is something we can change in the sample code? But below error happened: ``` Hyperledger.Indy.InvalidStructureException: A value being processed is not valid. at Hyperledger.Aries.Features.IssueCredential.DefaultCredentialService.IssueCredentialSafeAsync(IAgentContext agentContext, DefinitionRecord definitionRecord, CredentialRecord credentialRecord) ``` I am not sure whether I am using the correct process for the credential request. Kindly advise. Thanks.

Similar to @lijiachuan query. When a value is not valid, how do you know which value? Is there verbose logging in Indy?

Hi @davidd and @tomislav , I followed that sample code, but still encounter that error, below are details of my information, could you please take a look and suggest your ideas? Thanks a lot. The credential issuer retrieved: ``` { "schemaId":"MhMyTTDoxJptn2YtHF1s7j:2:CorporationSchema:1.0", "createdAt":"2020-06-15T14:54:23.3610216", "state":1, "credentialAttributesValues":[ { "name":"legalName", "mimeType":"application/json", "value":"MyCorp" }, { "name":"POCEmail", "mimeType":"application/json", "value":"test@aa.bb" }, { "name":"issuer", "mimeType":"application/json", "value":"CorpReg" }], "credentialID":"eb53b4d5-99a4-499f-93f9-e240a33cc6a4", "issuedByMe":true } ``` I used below function to response a request raised from the holder ``` [HttpPost("ResponseCredential")] public async Task ResponseCredential(CredentialModel model) { var context = await _agentContextProvider.GetContextAsync(); var offer = await _credentialService.GetAsync(context, model.CredentialID); var connection = await _connectionService.GetAsync(context, offer.ConnectionId); var (request, _) = await _credentialService.CreateCredentialAsync(agentContext: context, credentialId: model.CredentialID); await _messageService.SendAsync(context.Wallet, request, connection); return Ok(); } ``` But when execute `var (request, _) = await _credentialService.CreateCredentialAsync(agentContext: context, credentialId: model.CredentialID);`, below 500 error returned: ``` Hyperledger.Indy.InvalidStructureException: A value being processed is not valid. at Hyperledger.Aries.Features.IssueCredential.DefaultCredentialService.IssueCredentialSafeAsync(IAgentContext agentContext, DefinitionRecord definitionRecord, CredentialRecord credentialRecord) at Hyperledger.Aries.Features.IssueCredential.DefaultCredentialService.CreateCredentialAsync(IAgentContext agentContext, String credentialId, IEnumerable`1 values) at AriesFrameworkWebAPI.Controllers.CredentialsController.ResponseCredential(CredentialModel model) in C:\Git\SIP\AriesFramework\CorpReg\Controllers\CredentialsController.cs:line 175 at Microsoft.AspNetCore.Mvc.Infrastructure.ActionMethodExecutor.TaskOfIActionResultExecutor.Execute(IActionResultTypeMapper mapper, ObjectMethodExecutor executor, Object controller, Object[] arguments) at Microsoft.AspNetCore.Mvc.Infrastructure.ControllerActionInvoker.g__Awaited|12_0(ControllerActionInvoker invoker, ValueTask`1 actionResultValueTask) at Microsoft.AspNetCore.Mvc.Infrastructure.ControllerActionInvoker.g__Awaited|10_0(ControllerActionInvoker invoker, Task lastTask, State next, Scope scope, Object state, Boolean isCompleted) at Microsoft.AspNetCore.Mvc.Infrastructure.ControllerActionInvoker.Rethrow(ActionExecutedContextSealed context) at Microsoft.AspNetCore.Mvc.Infrastructure.ControllerActionInvoker.Next(State& next, Scope& scope, Object& state, Boolean& isCompleted) at Microsoft.AspNetCore.Mvc.Infrastructure.ControllerActionInvoker.g__Awaited|13_0(ControllerActionInvoker invoker, Task lastTask, State next, Scope scope, Object state, Boolean isCompleted) at Microsoft.AspNetCore.Mvc.Infrastructure.ResourceInvoker.g__Awaited|19_0(ResourceInvoker invoker, Task lastTask, State next, Scope scope, Object state, Boolean isCompleted) at Microsoft.AspNetCore.Mvc.Infrastructure.ResourceInvoker.g__Awaited|17_0(ResourceInvoker invoker, Task task, IDisposable scope) at Microsoft.AspNetCore.Routing.EndpointMiddleware.g__AwaitRequestTask|6_0(Endpoint endpoint, Task requestTask, ILogger logger) at Microsoft.AspNetCore.Authorization.AuthorizationMiddleware.Invoke(HttpContext context) at Microsoft.AspNetCore.Builder.Extensions.MapWhenMiddleware.Invoke(HttpContext context) at Hyperledger.Aries.AspNetCore.AgentMiddleware.Invoke(HttpContext httpContext, IAgentProvider agentProvider) at Microsoft.AspNetCore.Diagnostics.DeveloperExceptionPageMiddleware.Invoke(HttpContext context) HEADERS ======= Cache-Control: no-cache Connection: keep-alive Content-Type: application/json Accept: application/json, text/plain, */* Accept-Encoding: gzip, deflate, br Accept-Language: en-US,en;q=0.9 Host: localhost:5002 Referer: http://localhost:4100/credentials/list User-Agent: Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4103.97 Safari/537.36 Origin: http://localhost:4100 Content-Length: 55 Sec-Fetch-Site: same-site Sec-Fetch-Mode: cors Sec-Fetch-Dest: empty ```

tomislav (Mon, 15 Jun 2020 15:39:33 GMT):
You don't need to populate the `mime-type` field. I'm not sure what the support for this is.

tomislav (Mon, 15 Jun 2020 15:39:56 GMT):
Are you on the correct ledger for both agents?

tomislav (Mon, 15 Jun 2020 15:40:17 GMT):

tomislav (Mon, 15 Jun 2020 15:40:25 GMT):
All in all, what you're doing seems to be on the right track

tomislav (Mon, 15 Jun 2020 15:41:13 GMT):
Are you talking about Credential Proposal? No, it would be great to add this feature

tomislav (Mon, 15 Jun 2020 15:43:15 GMT):
Unfortunately, libindy errors `Hyperledger.Indy.InvalidStructureException: A value being processed is not valid.` don't communicate what was wrong exactly. There's no way for us to know, other then to turn on Indy logging or doing some guess work.

tomislav (Mon, 15 Jun 2020 15:43:34 GMT):
Can you debug all the way through the call that fails?

tomislav (Mon, 15 Jun 2020 15:43:57 GMT):
Are you passing all credential values present in the the schema? If any are missing, it will be problem

davidd (Mon, 15 Jun 2020 15:52:43 GMT):
@tomislav trying to issue credentials from web agent to osma, and I'm receiving the issued-credential encoding data in VS Code, but unable to show that in osma. any thing missing ?

lijiachuan (Mon, 15 Jun 2020 15:58:15 GMT):
Below is the schema object I used: ``` { "attr_names": [ "legalName", "POCEmail" ], "name": "CorporationSchema", "version": "1.0", "id": "MhMyTTDoxJptn2YtHF1s7j:2:CorporationSchema:1.0", "ver": "1.0", "seqNo": 8 } ``` Regarding credential values, the attributes in the offer are: ``` { "name":"legalName", "mimeType":"application/json", "value":"MyCorp" }, { "name":"POCEmail", "mimeType":"application/json", "value":"test@aa.bb" }, { "name":"issuer", "mimeType":"application/json", "value":"CorpReg" } ``` And these properties should be retrieved by `await _credentialService.CreateCredentialAsync(agentContext: context, credentialId: model.CredentialID)` where I just need to passed in the credentialID parameter. The only difference I can notice is the issuer which is not in the schema's definition.

tomislav (Mon, 15 Jun 2020 15:59:17 GMT):
Why is `issuer` part of the submitted values? It's not part of the schema

lijiachuan (Mon, 15 Jun 2020 16:00:00 GMT):
This was referred from the sample dot net core code in the aries framework

tomislav (Mon, 15 Jun 2020 16:00:32 GMT):
ok

tomislav (Mon, 15 Jun 2020 16:00:45 GMT):
the submitted values, must match the schema

lijiachuan (Mon, 15 Jun 2020 16:02:39 GMT):
whether we should remove this issuer value from the sample code? Am not sure why we added that previously, any special purpose.

lijiachuan (Mon, 15 Jun 2020 16:08:48 GMT):
That works if I removed the issuer property, so just would like to know is there any special reason to have that in the sample code.

That's definitely incorrect

lijiachuan (Tue, 16 Jun 2020 02:20:18 GMT):
Hi All, when we try to request a proof, whether we should specify which credential definition should be used for the proof? In the sample code, seems it only specified what are the proof fields but not specified which credential definition should be used. Whether this is required? Kindly advise. ``` public async Task CreateProofNameMessage(ConnectionRecord connectionRecord) { var agentContext = await _agentProvider.GetContextAsync(); var name = connectionRecord.Alias?.Name ?? connectionRecord.Id; var proofRequest = new ProofRequest { Name = "ProofReq", Version = "1.0", Nonce = await AnonCreds.GenerateNonceAsync(), RequestedAttributes = new Dictionary { {"firstname-required", new ProofAttributeInfo {Name = "firstname"}} } }; (var msg, _) = await _proofService.CreateRequestAsync(agentContext, proofRequest); return msg; } ```

lijiachuan (Tue, 16 Jun 2020 03:44:14 GMT):
Hi All, when we request a proof, except the credential fields, whether we should also specify which credential definition should be used? In the sample code, it only specified the proof attributes name.

syngin (Tue, 16 Jun 2020 06:58:01 GMT):
[ ](https://chat.hyperledger.org/channel/aries-framework-dotnet?msg=CqBDpFNZw6umwKtLL) how do you turn on Indy logging. Im getting a similar error generating proof: AnonCreds.ProverCreateProofAsync

HLFPOC (Tue, 16 Jun 2020 10:08:02 GMT):
Yes @tomislav , I think credential proposal can be used by holder to request a credential from an issuer. Are there any plans to add it in .net framework ?

HLFPOC (Tue, 16 Jun 2020 10:09:19 GMT):
I am working on building mobile based agent using aries .net framework and want to understand the approach to enable backup and recovery of the mobile wallet. 1. Is there any standard process/apis available for taking the wallet backup? 2. As mediator agent also stores the copy of the wallet, is it possible to export it from Mediator agent into mobile agent in case of recovery? 3. Any open-source implementation available which demonstrate backup/recovery feature ?

lijiachuan (Tue, 16 Jun 2020 12:49:14 GMT):
hi, I followed the sample code to send one proof request with below method: ``` [HttpPost] public async Task SendProofNameRequest(string connectionId) { var agentContext = await _agentProvider.GetContextAsync(); var connectionRecord = await _walletRecordService.GetAsync(agentContext.Wallet, connectionId); var proofNameRequest = await CreateProofNameMessage(connectionRecord); await _messageService.SendAsync(agentContext.Wallet, proofNameRequest, connectionRecord); return RedirectToAction("Index"); } public async Task CreateProofNameMessage(ConnectionRecord connectionRecord) { var agentContext = await _agentProvider.GetContextAsync(); var name = connectionRecord.Alias?.Name ?? connectionRecord.Id; var proofRequest = new ProofRequest { Name = "ProofReq", Version = "1.0", Nonce = await AnonCreds.GenerateNonceAsync(), RequestedAttributes = new Dictionary { {"firstname-required", new ProofAttributeInfo {Name = "firstname"}} } }; (var msg, _) = await _proofService.CreateRequestAsync(agentContext, proofRequest); return msg; } ``` But there is one question that, the name defined via `var name = connectionRecord.Alias?.Name ?? connectionRecord.Id;` is not used by any code, and after this request was submitted, the retrieved proof information's connectionID is null, also there is not one indicator/property which can let me know whether this proof is requested from my side or not. Can anyone provide some suggestions about this? Thanks.

tomislav (Tue, 16 Jun 2020 12:50:47 GMT):
There are multiple overloads of `CreateRequestAsync`, one is used for connectionless proofs, the other is for sending to connections.

lijiachuan (Tue, 16 Jun 2020 12:51:51 GMT):
ok, so for the type of connectionless proof request, how to know whether this is from my side or not?

tomislav (Tue, 16 Jun 2020 12:52:34 GMT):
What do you mean?

lijiachuan (Tue, 16 Jun 2020 12:53:39 GMT):
I am trying to based on one indicator to know whether one party is the requester or the prover, but in current returned proof information, there is no such indicator property, so I am not sure how to determine whether I am the requestor or the prover.

tomislav (Tue, 16 Jun 2020 12:54:14 GMT):
If you create the request, you are the requestor.

tomislav (Tue, 16 Jun 2020 12:54:49 GMT):
Connectionless proof can be encoded into a URL and shared with the holder

lijiachuan (Tue, 16 Jun 2020 12:55:13 GMT):
but imagine from the prover side, there is also one proof request record, but from the proof information, there is not a property to determine whether this is requested from the prover side or not

tomislav (Tue, 16 Jun 2020 12:55:35 GMT):
You can set a tag and track that

lijiachuan (Tue, 16 Jun 2020 12:58:08 GMT):
ok, whether this is not one must have property for a proof request?

tomislav (Tue, 16 Jun 2020 12:59:58 GMT):
you set the tag on the proofRecord, which is your own local record to track the state

lijiachuan (Tue, 16 Jun 2020 13:00:02 GMT):
In ACA-Py, there is one `initiator` property which value could be either `self` or `external`, so it's easy to know whether this request is from which side.

lijiachuan (Tue, 16 Jun 2020 13:00:51 GMT):
if this property can be one embeded property which doesn't need user specify manually, I think that would be good, not sure whether you are agree.

tomislav (Tue, 16 Jun 2020 13:00:53 GMT):
``` (var msg, record) = await _proofService.CreateRequestAsync(agentContext, proofRequest); record.SetTag("Initiator", "Self"): ```

lijiachuan (Tue, 16 Jun 2020 13:01:27 GMT):
otherwise, we need to let each developer set it manually

tomislav (Tue, 16 Jun 2020 13:01:55 GMT):
Sure, this can be added in the framework

lijiachuan (Tue, 16 Jun 2020 13:01:57 GMT):
but the problem is this value would be the same for both sides

tomislav (Tue, 16 Jun 2020 13:02:13 GMT):
No, it won't. The record doesn't travel around

tomislav (Tue, 16 Jun 2020 13:02:20 GMT):
the message does

lijiachuan (Tue, 16 Jun 2020 13:02:41 GMT):
ok, let me have a try

tomislav (Tue, 16 Jun 2020 13:03:05 GMT):
You must save the record after you add a tag, btw. `recordService.UpdateAsync`

lijiachuan (Tue, 16 Jun 2020 13:06:02 GMT):
btw, in the sample code, I saw there is one input box to let user type the connection id, but it is using a connectionless proof request, shall we change this to a connection proof request?

tomislav (Tue, 16 Jun 2020 13:06:50 GMT):
Yes. It shouldn't misguide the user

lijiachuan (Tue, 16 Jun 2020 13:07:04 GMT):
https://github.com/Yoroitchi/AriesWebApp/blob/c4618cb2db36b21d92bac8eba252b7f3d7b7f214/AriesWebApp/Views/Proof/SendProofRequestNameView.cshtml#L8

lijiachuan (Tue, 16 Jun 2020 13:23:35 GMT):
There is another disadvantage to use manual added tag for this purpose, which is after I use `_proofService.ListAsync(agentContext)` retrieved all proofs, then I need to loop this proofs, and get this tag and format a new objects array to the controller UI.

tomislav (Tue, 16 Jun 2020 13:42:39 GMT):
Isn't there an overload to use SearchQuery?

lijiachuan (Tue, 16 Jun 2020 13:44:27 GMT):
I would like to retrieve all proof requests related to me, I am not sure whether the SearchQuery can help, as I don't want to add any filter by default.

tomislav (Tue, 16 Jun 2020 13:50:00 GMT):
that's what the search query is for

tomislav (Tue, 16 Jun 2020 13:50:50 GMT):
SearchQuery.Equal("Intiator", "Self")

lijiachuan (Tue, 16 Jun 2020 13:51:36 GMT):
I mean I don't want to query all my initiated proof requests, but would like to get all the proof requests related to me, no matter whether I am the initiator or not.

tomislav (Tue, 16 Jun 2020 13:52:06 GMT):
what is "related to me"?

lijiachuan (Tue, 16 Jun 2020 13:52:11 GMT):
But this would be the workaround before we have the initiator indicator property

lijiachuan (Tue, 16 Jun 2020 13:52:29 GMT):
I requested, or someone requested to me.

tomislav (Tue, 16 Jun 2020 13:52:59 GMT):
so it's not built in, but it's easy to add it in your application

lijiachuan (Tue, 16 Jun 2020 13:54:30 GMT):
You mean separate the UI to two pages, one is showing all my initiated proof requests, the other one is showing all the proof requests which I received from others, right?

tomislav (Tue, 16 Jun 2020 14:01:55 GMT):
Whatever you choose, yes.

tomislav (Tue, 16 Jun 2020 14:02:09 GMT):
I'm saying you have the ability to track and filter them

lijiachuan (Tue, 16 Jun 2020 14:03:16 GMT):
ok, got it. So do you think this initiator property would be one enhancement?

tomislav (Tue, 16 Jun 2020 14:03:48 GMT):
Yeah, it seems to be an easy and useful addition

lijiachuan (Tue, 16 Jun 2020 14:04:14 GMT):
great to know this. Thanks

lijiachuan (Tue, 16 Jun 2020 14:22:55 GMT):
hi, may I know why do we defined two credential structures, one is `CredentialInfo`, the other one is `CredentialRecord`. I raise this question is due to I am trying to response one proof request, initially I plan to use `_credentialService.ListAsync(agentContext)` to retrieve all my credentials, it would be `CredentialRecord` type, so I can choose one credential for the proof request, but when I checked the sample code, it is using `await _proofService.ListCredentialsForProofRequestAsync(agentContext, request, requestedAttribute.Key)` to retrieve all credentials and use the first one for the request response. And this function returned `CredentialInfo` type. So this might be one question about the design of the credential data structure. Thanks.

tomislav (Tue, 16 Jun 2020 17:23:52 GMT):
`CredentialInfo` is a data model that indy uses internally. A consumer can iterrate over them and retrieve the corresponding `CredentialRecord` to display on UI.

tomislav (Tue, 16 Jun 2020 17:24:26 GMT):
We could do that in the framework, that's a good point

syngin (Wed, 17 Jun 2020 07:56:57 GMT):
For connectionless proof request, how does the holder return the proof response to the verifier? Does the controller need to store the routing keys, recipient keys and endpoint somewhere? Or is it handled within Aries?

lijiachuan (Wed, 17 Jun 2020 12:25:22 GMT):
hi @tomislav , do you mean there could be one change in the framework that will return the same type of credentials in these two methods `_credentialService.ListAsync` and `ListCredentialsForProofRequestAsync`?

tomislav (Wed, 17 Jun 2020 12:37:48 GMT):

Hi, there is a new question about using connection less proof or not, actually there are different structure requestJson generated, below is one sample requestJson generated by connection less proof request via `(var proofNameRequest, _) = await _proofService.CreateRequestAsync(agentContext, proofRequest);` ``` { "name":"06170905", "version":"1.0", "nonce":"580318057034241599988458", "requested_attributes":{ "legalName":{ "name":"legalName", "restrictions":[ { "cred_def_id":"MhMyTTDoxJptn2YtHF1s7j:3:CL:8:CorporationCredential" }] } }, "requested_predicates":{ } } ``` And below is one generated proof request from one connection required proof request via `(var proofNameRequest, var proofRecord) = await _proofService.CreateRequestAsync(agentContext, JsonConvert.SerializeObject(proofRequest), proofRequestModel.connectionID);` ``` { "name":"06170914", "version":"1.0", "nonce":"1192058500544631938939603", "requested_attributes":{ "legalName":{ "name":"legalName", "names":null, "restrictions":[ { "cred_def_id":"MhMyTTDoxJptn2YtHF1s7j:3:CL:8:CorporationCredential", "AttributeValue":null }] } }, "requested_predicates":{ } } ``` There are two properties(names and AttributeValue) with null value in the later case, my question would be for connection less or not, whether the only difference should be whether we need to specify the connection or not, but for the generated proof request, the only difference is one has a value for the connectionId, the other one value is null? For other part of the proof request, they should have the same structure?

lijiachuan (Wed, 17 Jun 2020 13:30:00 GMT):
What I want to implement is require the proof is based on one specified credential definition.

Hi, I tried to use `_proofService.VerifyProofAsync(agentContext, proofRecordId)` to verify a proof, I can receive a `true` if the credential's definition meet my expected definition, but when I used one different definition's credential for the verify, it didn't return a `false` but it returned below 500 error, is this a correct behavior? ``` Hyperledger.Indy.AnonCredsApi.ProofRejectedException: The proof has been rejected. at Hyperledger.Aries.Features.PresentProof.DefaultProofService.VerifyProofAsync(IAgentContext agentContext, String proofRequestJson, String proofJson, Boolean validateEncoding) at Hyperledger.Aries.Features.PresentProof.DefaultProofService.VerifyProofAsync(IAgentContext agentContext, String proofRecId) at AriesFrameworkWebAPI.Controllers.ProofsController.VerifyProof(String proofRecordId) in C:\Git\SIP\AriesFramework\CorpReg\Controllers\ProofsController.cs:line 121 at lambda_method(Closure , Object ) at Microsoft.AspNetCore.Mvc.Infrastructure.ActionMethodExecutor.AwaitableObjectResultExecutor.Execute(IActionResultTypeMapper mapper, ObjectMethodExecutor executor, Object controller, Object[] arguments) at Microsoft.AspNetCore.Mvc.Infrastructure.ControllerActionInvoker.g__Awaited|12_0(ControllerActionInvoker invoker, ValueTask`1 actionResultValueTask) at Microsoft.AspNetCore.Mvc.Infrastructure.ControllerActionInvoker.g__Awaited|10_0(ControllerActionInvoker invoker, Task lastTask, State next, Scope scope, Object state, Boolean isCompleted) at Microsoft.AspNetCore.Mvc.Infrastructure.ControllerActionInvoker.Rethrow(ActionExecutedContextSealed context) at Microsoft.AspNetCore.Mvc.Infrastructure.ControllerActionInvoker.Next(State& next, Scope& scope, Object& state, Boolean& isCompleted) at Microsoft.AspNetCore.Mvc.Infrastructure.ControllerActionInvoker.g__Awaited|13_0(ControllerActionInvoker invoker, Task lastTask, State next, Scope scope, Object state, Boolean isCompleted) at Microsoft.AspNetCore.Mvc.Infrastructure.ResourceInvoker.g__Awaited|19_0(ResourceInvoker invoker, Task lastTask, State next, Scope scope, Object state, Boolean isCompleted) at Microsoft.AspNetCore.Mvc.Infrastructure.ResourceInvoker.g__Awaited|17_0(ResourceInvoker invoker, Task task, IDisposable scope) at Microsoft.AspNetCore.Routing.EndpointMiddleware.g__AwaitRequestTask|6_0(Endpoint endpoint, Task requestTask, ILogger logger) at Microsoft.AspNetCore.Authorization.AuthorizationMiddleware.Invoke(HttpContext context) at Microsoft.AspNetCore.Builder.Extensions.MapWhenMiddleware.Invoke(HttpContext context) at Hyperledger.Aries.AspNetCore.AgentMiddleware.Invoke(HttpContext httpContext, IAgentProvider agentProvider) at Microsoft.AspNetCore.Diagnostics.DeveloperExceptionPageMiddleware.Invoke(HttpContext context) HEADERS ======= Cache-Control: no-cache Connection: keep-alive Content-Type: application/json Accept: application/json, text/plain, */* Accept-Encoding: gzip, deflate, br Accept-Language: en-US,en;q=0.9 Host: localhost:5002 Referer: http://localhost:4100/proofs/list User-Agent: Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4103.97 Safari/537.36 Origin: http://localhost:4100 Content-Length: 2 Sec-Fetch-Site: same-site Sec-Fetch-Mode: cors Sec-Fetch-Dest: empty ```

hi @tomislav , I just noticed that there is a default created tag for a proof, which name is `role`, and value could be either `requestor` or `holder`, if we could add one `IsRequestedByMe` property for the proof object, which value is based on this tag's value, that would be helpful, otherwise, developer needs to add this indicator manually. This would be the same for the credential object, if there could be one `IssuedByMe` property which value is based on the tag `role` value.

Can anyone please share the approach on enabling backup and recovery in mobile agent?

tomislav (Thu, 18 Jun 2020 12:52:55 GMT):
There's no sample done yet, we should create one. It is however very simple to use. You want to call CreateBackup on the mobile side, and then using the same phrase, call RestoreBackup

tomislav (Thu, 18 Jun 2020 12:53:51 GMT):
There's a unit test for this - https://github.com/hyperledger/aries-framework-dotnet/blob/3b500302c989b69790f0dc63ce15633017008126/test/Hyperledger.Aries.Tests/Routing/BackupTests.cs#L107

HLFPOC (Thu, 18 Jun 2020 13:05:15 GMT):
Thanks for the inputs @tomislav . Where does this backup is stored after calling the CreateBackup ? Is there any document which explains the whole process ?

tomislav (Thu, 18 Jun 2020 13:05:55 GMT):
It's stored on the mediator's filesystem. You can set the backup location in the agent options

tomislav (Thu, 18 Jun 2020 13:06:02 GMT):
There's no document yet

tomislav (Thu, 18 Jun 2020 13:06:35 GMT):
https://github.com/hyperledger/aries-framework-dotnet/blob/master/src/Hyperledger.Aries.Routing.Mediator/Storage/DefaultStorageService.cs

HLFPOC (Thu, 18 Jun 2020 13:08:10 GMT):
okay, and is there any option to change the storage type from filesystem to a db for mediator agent ?

tomislav (Thu, 18 Jun 2020 13:32:06 GMT):
Yes, the option would be to implement the IStorageService

zossimov (Thu, 18 Jun 2020 13:37:43 GMT):
@tomislav actually in our web agent there is complete functionality for Issuer, Holder, Verifier to issue, receive, verify, proof of credentials. but i was asking is there any implementation in osma (holder) to receive/store credentials in wallet (which is issued by issuer) ?

tomislav (Thu, 18 Jun 2020 13:40:13 GMT):
I believe there is, but it may not be available to respond to proof requests

zossimov (Thu, 18 Jun 2020 13:42:08 GMT):
in osma app, for now I just want to receive creds and store it in wallet

swcurran (Thu, 18 Jun 2020 13:42:15 GMT):
@sukalpomitra has had it working for holding and proving. He's gotten the BC Gov uses cases working. He has using his own mediator. You will need a mediator to do it.

swcurran (Thu, 18 Jun 2020 13:42:29 GMT):
FYI - it's now Aries-MAX and is part of Hyperledger.

zossimov (Thu, 18 Jun 2020 13:42:54 GMT):
the issued creds to holder (osma) can be visible in app

zossimov (Thu, 18 Jun 2020 13:43:27 GMT):
@swcurran yes i know about Aries-MAX, and as I said, Web Agent is working fine, mediator is running

zossimov (Thu, 18 Jun 2020 13:44:54 GMT):
we have 3 web agents, for issuer, holder and verifier and mediator and it's working perfectly

zossimov (Thu, 18 Jun 2020 13:45:28 GMT):
now we just want to add the osma app in that circle, means that issued creds can be store and visible for user (holder)

hi @tomislav , may I have your suggestion about how to create one automatically request and response for a credential? Thanks.

tomislav (Tue, 23 Jun 2020 01:27:26 GMT):
You want to do this in the credential handler

tomislav (Tue, 23 Jun 2020 01:27:43 GMT):
You can either override the default one, or write a new based on the same code

lijiachuan (Tue, 23 Jun 2020 01:29:14 GMT):
So this is not from a subscription of the receiving message, right?

tomislav (Tue, 23 Jun 2020 01:30:39 GMT):
That's one way of doing it, but I can't confirm that specific implementation.

lijiachuan (Tue, 23 Jun 2020 01:32:07 GMT):
"Do this in the credential handler", do you mean in a credential controller function?

tomislav (Tue, 23 Jun 2020 01:32:27 GMT):
No, I mean DefaultCredentialHandler.cs

tomislav (Tue, 23 Jun 2020 01:32:33 GMT):
you can write your own handler

lijiachuan (Tue, 23 Jun 2020 01:34:26 GMT):

Hi all, when I tried to create a new wallet then get this wallet's issuer information, I encountered one problem. I use below codes to create a new wallet ``` public async Task CreatWallet(WalletModel model) { var config = new WalletConfiguration { Id = model.walletName }; var creds = new WalletCredentials { Key = model.walletCredential }; await _walletService.CreateWalletAsync(config, creds); var wallet = await _walletService.GetWalletAsync(config, creds); var issuer = await _provisionService.GetProvisioningAsync(wallet); return Ok(); } ```

tomislav (Thu, 25 Jun 2020 13:26:00 GMT):
creating a wallet on it's own doesn't create the agent required configuration. You need to call `ProvisionAsync` in the service to have this record created.

Hope this can help. I also paste more code in the private chat.

tomislav (Tue, 30 Jun 2020 12:58:41 GMT):
It is possible, as the postgres plugin can be plugged in independently. You want to register the plugin first, by making a native call to the C library, and then you can use the storage mapping in `WalletConfiguration.StorageType`, for example when you call `RegisterAgent(AgentOptions)`

lijiachuan (Tue, 30 Jun 2020 16:15:35 GMT):

if you are using aca-py then as per my best knowledge `--auto-respond-credential-request` need to set while you start aca-py.

lijiachuan (Tue, 30 Jun 2020 16:23:06 GMT):
And this will also be helpful for the proof request, when received a proof request from the verifier, if the holder also can automatically select one proper credential and return back, then the verifier automatically verify the credentials, this would be great.

sheru (Tue, 30 Jun 2020 16:25:17 GMT):
Yes this can be also automate. I used aca-py as the cloud agent. Not sure how it can be done in the dot net one.

tomislav (Tue, 30 Jun 2020 17:39:22 GMT):
Can be implemented very easy. Add option in AgentOptions to toggle this setting. In credential handler inside the credential request block, check the setting, if automatic is on, issue credential

Hi all, When we offered creds to holder, it is by default stored in holder wallet, next we have to "Create a credential request on offered creds" (*CreateRequestAsync*) and in response (from issuer), we will get the Issue Status (*CreateCredentialAsync*). Now, I'm on *CreateRequestAsync *step, I created a button in osma, to '*Accept Offer*', which calls this *ProcessOffer()* function (https://github.com/Yoroitchi/AriesWebApp/blob/509d6556b8cb0f0584505a6ece5e38acf415e966/AriesWebApp/Controllers/CredentialsController.cs#L48).* In response I get this Error.* ``` 07-01 05:23:32.622 D/Mono ( 2114): Loading reference 11 of /storage/emulated/0/Android/data/com.osma/files/.__override__/Hyperledger.Aries.dll asmctx DEFAULT, looking for Polly, Version=7.0.0.0, Culture=neutral, PublicKeyToken=c8a3ffc3f8f825cc 07-01 05:23:32.623 D/Mono ( 2114): Assembly Ref addref Hyperledger.Aries[0x98a21660] -> Polly[0x98a22ec0]: 2 07-01 05:23:32.691 D/Mono ( 2114): DllImport searching in: 'indy' ('libindy.so'). 07-01 05:23:32.691 D/Mono ( 2114): Searching for 'indy_build_get_cred_def_request'. 07-01 05:23:32.691 D/Mono ( 2114): Probing 'indy_build_get_cred_def_request'. 07-01 05:23:32.691 D/Mono ( 2114): Found as 'indy_build_get_cred_def_request'. 07-01 05:23:32.726 D/Mono ( 2114): DllImport searching in: 'indy' ('libindy.so'). 07-01 05:23:32.726 D/Mono ( 2114): Searching for 'indy_set_protocol_version'. 07-01 05:23:32.726 D/Mono ( 2114): Probing 'indy_set_protocol_version'. 07-01 05:23:32.726 D/Mono ( 2114): Found as 'indy_set_protocol_version'. 07-01 05:23:32.746 D/Mono ( 2114): DllImport searching in: 'indy' ('libindy.so'). 07-01 05:23:32.747 D/Mono ( 2114): Searching for 'indy_open_pool_ledger'. 07-01 05:23:32.747 D/Mono ( 2114): Probing 'indy_open_pool_ledger'. 07-01 05:23:32.747 D/Mono ( 2114): Found as 'indy_open_pool_ledger'. **Hyperledger.Indy.PoolApi.PoolConfigNotCreatedException:** 'The requested pool cannot be opened because it does not have an existing configuration.' ```

It looks like your pool configurations didn't get created. Try running the service, or verify it gets executed, `PoolConfigurator.ConfigurePoolAsync`. This should execute on startup, but you can also run it manually.

tomislav (Wed, 01 Jul 2020 13:00:54 GMT):
When you click on Create Agent the first time, it should execute this code https://github.com/hyperledger/aries-mobileagent-xamarin/blob/cb56d53f4e8a3da45cefa65503960b9e52e71099/src/Osma.Mobile.App/ViewModels/RegisterViewModel.cs#L43

tomislav (Thu, 02 Jul 2020 12:36:19 GMT):
Have you added basic message handler to your agent? `AddBasicMessage()`?

how can I add basic message handler to the agent. Please guide me.

tomislav (Thu, 02 Jul 2020 13:02:42 GMT):
if youre using the default configuration, you should already have basic message handler

tomislav (Thu, 02 Jul 2020 13:02:49 GMT):
you are receiving messages

tomislav (Thu, 02 Jul 2020 13:03:26 GMT):
you can list them using `recordService.SearchAsync

Hi all, in `DefaultCredentialHandler.cs` `ProcessAsync` function, in `case MessageTypes.IssueCredentialNames.RequestCredential`, it has one checking as `if (request.ReturnRoutingRequested() && messageContext.Connection == null)`, does anyone know what does this checking mean? Only meet this criteria then it will create a credential, otherwise nothing will be created, I didn't get what this checking is for. Anyone has idea about this? Thanks

Is `_credentialService.CreateCredentialAsync` the corresponding action for a credential request from the holder?

x0axz (Fri, 03 Jul 2020 18:08:57 GMT):
`CreateRequestAsync()`, create a credential request by the holder for the given record on a previously received offer. The credential record must be in state "Offered". `CreateCredentialAsync()`, Create a credential based on an offer message. If successful, this method will return a credential record in "Issued" state.

x0axz (Fri, 03 Jul 2020 18:08:57 GMT):
`CreateRequestAsync()`, holder create a credential request for the given record on a previously received offer. The credential record must be in state "Offered". `CreateCredentialAsync()`, Issuer create a credential based on an offer message. If successful, this method will return a credential record in "Issued" state.

lijiachuan (Fri, 03 Jul 2020 18:13:00 GMT):
thanks for your reply, but my remain question is why `CreateCredentialAsync` only happened when `if (request.ReturnRoutingRequested() && messageContext.Connection == null)` is true. Any idea?

x0axz (Fri, 03 Jul 2020 18:41:42 GMT):
I don't know what u mean by that, but this is the function I'm using to Send Credentials to Holder. ``` var agentContext = await _agentContextProvider.GetContextAsync(); var credentialRecord = await _credentialService.GetAsync(agentContext, id); var connectionRecord = await _connectionService.GetAsync(agentContext, credentialRecord.ConnectionId); (var cred, var credentialRecordIssued) = await _credentialService.CreateCredentialAsync(agentContext: agentContext, credentialId: id); await _messageService.SendAsync(agentContext.Wallet, cred, connectionRecord); ```

lijiachuan (Fri, 03 Jul 2020 18:50:08 GMT):
ok, I am adding automate features for credential handler, which can enable: - Holder automatically request a credential after receiving an offer - Issuer automatically issue a credential after receiving a credential request And this change is in `DefaultCredentialHandler.cs`. If you check the code, there is one part about how to handle credential request message, as below: ``` case MessageTypes.IssueCredentialNames.RequestCredential: { var request = messageContext.GetMessage(); var recordId = await _credentialService.ProcessCredentialRequestAsync( agentContext: agentContext, credentialRequest: request, connection: messageContext.Connection); if (request.ReturnRoutingRequested() && messageContext.Connection == null) { var (message, record) = await _credentialService.CreateCredentialAsync(agentContext, recordId); messageContext.ContextRecord = record; return message; } else { messageContext.ContextRecord = await _credentialService.GetAsync(agentContext, recordId); return null; } } ``` So there is one check `if (request.ReturnRoutingRequested() && messageContext.Connection == null)`, I am not sure what this check is for, seems only meet this criteria then it will create a credential, otherwise, nothing will be created.

lijiachuan (Fri, 03 Jul 2020 18:58:33 GMT):
And this is the line of code which I am not sure the checking purpose. https://github.com/hyperledger/aries-framework-dotnet/blob/e2a99e7bd3c4d77c3c765b2a4b37470d075f4cb6/src/Hyperledger.Aries/Features/IssueCredential/DefaultCredentialHandler.cs#L76

x0axz (Fri, 03 Jul 2020 19:02:17 GMT):
sorry, don't have any idea, but it looks like they are checking for, either they get the Request from Holder, to Issue them credentials. States of Credentials: Offered -> Issuer to Holder Requested -> Holder to Issuer Issued -> Issuer to Holder ReturnRoutingRequested() -> https://github.com/hyperledger/aries-framework-dotnet/blob/master/src/Hyperledger.Aries/Decorators/Transport/TransportDecoratorExtensions.cs#L28

x0axz (Fri, 03 Jul 2020 19:04:09 GMT):
u have two agents or one?

tomislav (Sun, 05 Jul 2020 00:37:46 GMT):
It is used for return routing support. If you specify return route in your request, the result will be given in the http response, isntead going over peer connection

lijiachuan (Sun, 05 Jul 2020 09:16:14 GMT):
so if we specified the return route, one `CreateCredentialAsync` will be invoked, if not specify the return route, it won't create credential. As this is for `MessageTypes.IssueCredentialNames.RequestCredential` this type of message, so does this mean, if received a `RequestCredential` message and there is not specified return route, then we don't need to create a credential for this request, is this correct?

Hello, I want to verify a proof response, and the proof request wasn't created by me. Actually I want to be a third party Verifier but don't want to hold user data (sent in response to me for verification). How can I implement that (flow of verification for this specific scenario)?

lijiachuan (Sun, 05 Jul 2020 14:29:10 GMT):
From your description, you are still a verifier role, I am not sure what's the reason that you don't want to initialize a proof request but want to verify a credential which requested from others. I think verify a credential doesn't need to hold/save the credential data, just need to verify the result, so whether a normal proof verification process can work?

x0axz (Sun, 05 Jul 2020 20:15:57 GMT):
Here is our system design: We have multiple Issuers and every Issuer has their own user base (Holders). We want to function as Verifier, to verify the Proof Request on behalf of Issuers. Issuer wants to verify a holder, the issuer will first sent a proof request to Verifier (us) (we won't store/hold it). We will then forward this request to holder, they in response will sent us the proof (again, we don't want to know anything about it, we want to apply ZKP). We will verify the proof request. As the Credentials are stored in Holder Wallets, when Issuer sent us request to verify the credentials of Holder, we (verifier) don't want to store/hold/log the credentials in any way.

you may be trying to use a pool without creating it first. It probably works outside docker because the config is already stored somewhere on your local in ~/.indy_client. Use Pool.CreatePoolLedgerConfigAsync to create and provide a genesis file.

syngin (Thu, 09 Jul 2020 02:12:57 GMT):
i think with proofs, the credentials are never sent. and with ZKP neither is the actual attribute. The verifier doesn't have to be the issuer. As verifiier I think you can make your own proof request.

Hi all, On web agent, I created Input field to ask for holder's passport number in plaintext. Will hash/encode this value with same algorithm, which was used at a time of credential issuance. To validate both hash values (one stored in wallet, issued at a time of credential issuance AND second, the generated hashed value on web agent). This is the function which encode the credential attribute: https://github.com/hyperledger/aries-framework-dotnet/blob/10c89e4938deb386bf9ec013e383e3c7bb7ffcc6/src/Hyperledger.Aries/Utils/CredentialUtils.cs#L54 But now I can't use this method because it's an Internal method. any help on how to implement this functionality? cc: @tomislav @lijiachuan

lijiachuan (Fri, 10 Jul 2020 11:53:30 GMT):
hi @davidd , I am not sure why you need to hash it manually, do you plan to use comparing hash approach to validate the credential?

davidd (Fri, 10 Jul 2020 12:02:40 GMT):
yes

davidd (Fri, 10 Jul 2020 12:03:57 GMT):
any help?

tomislav (Fri, 10 Jul 2020 12:05:40 GMT):
The verify function already compares the hashed values for encoding. Can you just run verify?

tomislav (Fri, 10 Jul 2020 12:06:05 GMT):
Else, we can make the method public, just not sure that would have common use

davidd (Fri, 10 Jul 2020 12:07:45 GMT):
can I use it on web agent?

davidd (Fri, 10 Jul 2020 12:08:11 GMT):
like if I write the method in controller, will it be helpful?

tomislav (Fri, 10 Jul 2020 12:08:26 GMT):
There may already be one

tomislav (Fri, 10 Jul 2020 12:08:47 GMT):
there's a swagger controller support in the framework now

lijiachuan (Fri, 10 Jul 2020 12:11:21 GMT):
``` [HttpPost("VerifyProof/{proofRecordId}")] public async Task VerifyProof(string proofRecordId) { var agentContext = await _agentProvider.GetContextAsync(); return await _proofService.VerifyProofAsync(agentContext, proofRecordId); } ``` This is the code I practiced, you can have a try.

davidd (Fri, 10 Jul 2020 12:18:45 GMT):
Thanks for that.. here is what I want. Both of hash values will be provided in two different parts. Credentials are issued in two forms, Raw & Encoded. Holder has to enter Passport Number in Raw form on web agent, it will be Encoded and then store in wallet. Holder will separately provide the Passport Number in Encoded form (which was stored in wallet on Phone), which will then be verify with the previous encoded value.

davidd (Fri, 10 Jul 2020 12:18:54 GMT):
I hope it make sense

lijiachuan (Fri, 10 Jul 2020 12:19:59 GMT):
who is the issuer?

davidd (Fri, 10 Jul 2020 12:20:46 GMT):
a third person (identity provider), in this flow Issuer won't be involve.

davidd (Fri, 10 Jul 2020 12:21:23 GMT):
it's just holder and verifier

davidd (Fri, 10 Jul 2020 12:21:54 GMT):
I just want to encode the passport number, which is in raw form and store it in wallet!

davidd (Fri, 10 Jul 2020 12:22:20 GMT):
later, will validate it with hash value provided by holder

lijiachuan (Fri, 10 Jul 2020 12:22:43 GMT):
so why the verifier need to verify it, that value is provided from the holder self, what should be the criteria to say, this is an expected credential or not

davidd (Fri, 10 Jul 2020 12:24:20 GMT):
just want to encode the raw data.. that's it. is there any solution for that?

tomislav (Fri, 10 Jul 2020 13:13:37 GMT):
Yes, make the method public

tomislav (Fri, 10 Jul 2020 13:14:10 GMT):
You can also just copy the method into your code right now and use it, it has no dependencies

Now in `public async Task HashedPassportNumber(string EncodePassportNumber)` i'm trying to store this hashed value in wallet and fetch it whenever and wherever I want. But as for that we have to create a model, for proof there is `ProofRequest`, for messages there is `BasicMessageRecord`, `BasicMessage` e.t.c. I just want to store `passportNumber in plaintext`, `hashed value of passportNumber` and `status`. how can I achieve it. thanks

Hi All, My scenario is Connectionless Proof Presentation with Revocable Credentials. My error is "A value must be provided. (Parameter 'masterSecret')". It seems agentContext.MasterSecretId returns null. Questions: 1. Where did I go wrong? 2. When does the mastersecret get set? During wallet provisioning? During credential accept? 3. I tried to get as mastersecret using AnonCreds.ProverCreateMasterSecretAsync(agentContext.Wallet, null); and use that in my verification presentation but it was accepted as not valid. Why? Does being a connectionless scenario factor into it?

syngin (Tue, 14 Jul 2020 09:06:31 GMT):
To answer my own questions. 1. Somehow the wallet was created without a MasterSecret. 2. It gets set when the wallet is created. A MasterSecret is created with every wallet. To be sure, run _provisionService.ProvisionAgentAsync(); And check the MasterSecretId of the newly created wallet. 3. No, its not related to the conenctionless scenario. When in doubt, update indy and aries to the latest versions, and clear all old data. I found other annoying but not showstopping bugs were eliminated when upgraded to the latest indy and aries libraries. Maybe the bug where master secret is not generated was part of an older aries/indy version. Clearing the old wallet data also helps I guess.

the issued credentials in wallet contains the `master_secret` in encoded form is same for every credential record ?

tomislav (Tue, 14 Jul 2020 12:30:26 GMT):
The `IEventAggregator` helps you hook into specific events. Additionally, you can implement `IAgentMiddleware` to intercept the agent message processing pipeline.

syngin (Wed, 15 Jul 2020 07:11:06 GMT):
i think there's potentially many master secrets identified by Ids. For proof presentation (in aries), i believe it uses the default master secret. I suppose you could work at the indy level to use a different master secret. I've not explored this topic further since I was able to get a successful proof verification.

tomislav (Wed, 15 Jul 2020 14:21:19 GMT):
Master secret is created at wallet provisioning.

tomislav (Wed, 15 Jul 2020 14:21:56 GMT):
You can have multiple master secrets, but you won't be able to link the credentials against the same master secret if you use multiple

tomislav (Wed, 15 Jul 2020 14:22:26 GMT):
I don't know of a codebase that currently works with multiple master secrets. It's definitely possible

Hi all, I'm working on Presentation Proof. Everything is working fine, Verifier is able to sends a Proof Request to Holder. Holder sends back a Proof Request with Credentials. But I want to verifiy these Credentials blindly (without knowing anything about it). *A Method which verifies the Request* ``` public bool VerifyNamedAndrie(PartialProof proof) { var name = proof.RequestedProof.RevealedAttributes.First(); if (name.Value.Raw.Equals("Andrie")) { return true; } return false; } ``` The Problem is with this last Method (*VerifyNamedAndrie*) is that *Verifier* has to know what's the *FirstName of Holder* is. How can I verify the *Attributes *(first name or anything) *blindly* (without knowing anything about it)?

syngin (Fri, 17 Jul 2020 10:07:09 GMT):
I think if you don't want to reveal the attributes, you would use predicates. However for strings, it doesn't really make sense, since you have to compare against a known string. If it matches, then you know what the attribute is - indirectly. It still protects the privacy of people not named Andrie. Maybe that's enough.

syngin (Thu, 23 Jul 2020 00:44:48 GMT):
not familiar with macOS dev, but one of the issues I had with indy was forgetting to set the environment variable "You need add the path to lib folder to LIBRARY_PATH environment variable." I'm guessing either this issue or the other sub libraries needed e.g. libsodium, zeromq, openssl. Maybe a configuration program could be included to advise which libraries are missing.

mboyd (Thu, 23 Jul 2020 02:54:30 GMT):
@ajayjadhav I have only been able to get aspnetcore to recognize Indy by putting the libindy.dylib directly in the bin/debug/netstandard2.0 directory

mboyd (Thu, 23 Jul 2020 02:55:04 GMT):
Something to do with how the build links to a version of libsodium

@ajayjadhav I am still just copying the dylib manually for each project I run, when I use MacOS. I think there's a way to set `DYLD_LIBRARY_PATH` to point to where your libindy.dylib is, but for me it's not working right. It used to, but not anymore

tomislav (Thu, 23 Jul 2020 16:27:20 GMT):
I've sort of given up trying and just copy the static lib for now

tomislav (Thu, 23 Jul 2020 16:29:04 GMT):
As @mboyd pointed out, if you copy the library in the `bin/Debug/netcoreapp3.1` output of your application, it should find it. As far as building it, you can just use the script in `indy-sdk/libindy/mac.build.sh` to build it

ajayjadhav (Thu, 23 Jul 2020 17:38:48 GMT):
Thanks @tomislav & @mboyd, I will give it a try

ajayjadhav (Thu, 23 Jul 2020 17:55:14 GMT):
Great, I am able to run the `aspnetcore` sample now after running `mac.build.sh` and putting the `libindy.dylib` in the `samples/aspnetcore/bin/Debug/netcoreapp3.1/` directory..

ajayjadhav (Thu, 23 Jul 2020 17:55:22 GMT):

Hi @tomislav, we are to using `aries-framework-dotnet` for setting up a cloud-based shared agent to manage custodial wallets. My colleague @RinkalBhojani is able to do it by making some changes to be able to create & manage multiple wallets. Do you think we can raise a PR for these changes to go into master?

What is the way to replace a default service? I can't get it to work. I've tried using the following two lines, both separate and together in the `ConfigureServices` function in `Startup.cs`, but it keeps using the `DefaultCredentialService`: ``` services.AddExtendedCredentialService(); services.AddSingleton(); ``` `CredentialService` extends `DefaultCredentialService` and only overrides the `ProcessOfferAsync` function. Any help is appreciated!

@syngin For Trinsic (formerly Streetcred ID) specific questions you can ask on our forum here: https://docs.trinsic.id/discuss

rileyphughes (Tue, 28 Jul 2020 18:00:12 GMT):
The answer is that the limit is not based on the size of an attribute, but on the total credential payload. At about 40,000 characters in the whole offer, you shouldn't have any issues. Anything above 45,000 characters and the API will reject it.

swcurran (Tue, 28 Jul 2020 18:06:22 GMT):
Is that because of an Indy limit or because of checking done in Trinsic?

syngin (Wed, 29 Jul 2020 01:57:46 GMT):
@rileyphughes thanks riley.

rileyphughes (Wed, 29 Jul 2020 03:09:44 GMT):
Not based on checking done by us. We're not sure if it's an Indy thing or an Aries thing, but it's something lower level.

swcurran (Wed, 29 Jul 2020 03:41:11 GMT):
Thanks - I've had questions about how big a credential can be and I've wondered.

Did you do this after you added core aries services? It should work, it's just the .NET Core DI

tomislav (Thu, 30 Jul 2020 12:00:40 GMT):
It's the custom wallet storage limitation, not indy.

TimoGlastra (Thu, 30 Jul 2020 12:35:41 GMT):
I did it before the `AddAriesFramework` and inside the `AddAriesFramework` call. Haven't tried doing it after `RegisterAgent` or `AddAriesFramework`. Not sure why I haven't tried that yet. Thanks!

tomislav (Tue, 11 Aug 2020 16:45:00 GMT):
So that's a more complex task. You would have to write custom services to provide full support for that. ILedgerService, ICredentialService, IProofService, etc.

tomislav (Tue, 11 Aug 2020 16:46:24 GMT):
However, the way all Aries frameworks are implemented now is they rely heavily on Indy wallets for storage. If you were to use Aries with a different credential signature scheme, you probably want your own storage too.

tomislav (Tue, 11 Aug 2020 16:46:45 GMT):
I'd be happy to help with efforts for this

Moshe7 (Tue, 11 Aug 2020 20:58:27 GMT):
Thanks, this is what I thought, I wanted to know if the link of Aries Dotnet's in my first post is the only package relevant to Indy ledger? my thinking is to use another type of blockchain only to create DID for entities, so regarding the storage in Indy wallet, it is a problem to use a Credential signature scheme of Indy for another type of ledger, for example, Ethereum? Thank you for your kindness to help, I'm actually thinking on port Aries also to Dart, I understand that the Aries dotnet is the most Aries mature project to learn from.

Hi all, I have one question about how can I prove one DID is mine? The reason why I asked this is I am thinking about a scenario that, one service can be accessible only if you have one valid DID and you can prove that DID is yours, but I am not sure how can implement this. Anyone can help? Thanks.

Prooving DID ownership is as simple as signing a message with it.

tomislav (Tue, 15 Sep 2020 22:52:49 GMT):
You can use the indy API to export the wallet. `Hyperledger.Indy.Sdk.WalletApi.ExportAsync`

Hi, i´m following this repo "https://github.com/hyperledger/aries-mobileagent-xamarin" for do a Xamarin proyect, but i have problem when i run the app and i try to create a wallet, it said to me "failed to create wallet : the subsystem network fall" , before it i try to run the mediator dotnet run , but the shell said "Unable to load DLL 'indy' or one of its dependencies: Can´t find the specifil module (0x8007007E)" . Can anybody help me ? thanks

lijiachuan (Tue, 22 Sep 2020 03:22:00 GMT):
hi all, is there any document about how to setup the "routing" agent with the mobile agent? As mobile agent doesn't have one endpoint which can be found by others, so I think there should be a "routing" agent which will be used by the mobile agent, but not sure how should I setup that. Anyone can suggest, is the "routing" agent the same as one normal agent(python or dotnet)? Thanks.

sheru (Tue, 22 Sep 2020 11:32:27 GMT):
@lijiachuan https://github.com/hyperledger/aries-mobileagent-xamarin here you will find a mediator directory which have the code for the mediator agent. Its build on .net. from inside the mediator directory run `dotnet run` to run the mediator service for the mobile applications.

lijiachuan (Tue, 22 Sep 2020 13:33:07 GMT):
Thanks @sheru for your reply, and I also have one question want to confirm is, which version of libindy and .NET framework the xamarin framework can support, I didn't find this information. Do you have any idea?

Good day all, While trying to upload the iOS app which we are building we got an issue from Apple Store.Can any one suggest what should be done to get through it.The issue from Apple store- ITMS-90338: Non-public API usage - The app references non-public selectors in Osma.Mobile.App.iOS: behaviorTypes, convolutionState, discoverAllContactUserInfosWithCompletionHandler:, discoverAllContactsCompletionBlock, discoverUserInfoWithEmailAddress:completionHandler:, discoverUserInfoWithUserRecordID:completionHandler:, discoverUserInfosCompletionBlock, displayContact, drawableResizesAsynchronously, encodeToCommandBuffer:sourceImage:convolutionState:, encodeToCommandBuffer:sourceImage:destinationImage:state:, getProperty:onChannel:responseHandler:, hasProperty:onChannel:responseHandler:, initWithEmailAddresses:userRecordIDs:, initWithMIDIEntity:dataReadyHandler:, initWithZoneID:options:, initWithZoneID:subscriptionID:options:, isPathExtensionHidden, isPublicDatabase, isUserExecutable, isUserReadable, isUserWritable, mouseUpAction, newDrawable, propertyChangedCallback, removeAllAppearanceStreams, replaceTextStorage:, retrieveConnectedPeripherals, retrievePeripherals:, setDiscoverAllContactsCompletionBlock:, setDiscoverUserInfosCompletionBlock:, setDrawableResizesAsynchronously:, setEditedMask:, setMouseUpAction:, setProperty:onChannel:responseHandler:, setPropertyChangedCallback:, setSocketFamily:, setTemporaryAttributes:forCharacterRange:, setUserRecordIDs:, sourceOffset, subscriptionOptions, takeBackgroundColorFrom:, takePasswordFrom:, temporalAntialiasingEnabled, userRecordIDs.

tomislav (Tue, 22 Sep 2020 17:37:51 GMT):
I suggest looking into updating to latest Xamarin Forms

tomislav (Tue, 22 Sep 2020 17:38:50 GMT):
As a rule of thumb, the Xamarin team keeps the API compatible with Apple's guidelines in terms of stripping internal and unused symbols. I'm assuming your build also has linker stripping support.

There is no any new log generated in the mediator's command window, whether it is due to my mobile app could not connect to the mediator?

lijiachuan (Wed, 23 Sep 2020 13:28:20 GMT):
am using the default localhost:5000 for the mediator

sheru (Wed, 23 Sep 2020 13:29:58 GMT):
the genesis is on the mobile app one not in the mediator one. Thanks Hope this will helpful for you.

lijiachuan (Wed, 23 Sep 2020 13:41:06 GMT):
hi, I found there are 4 genesis files in the Android project's Assets folder, may I know why there are 4 genesis files? I have one test Indy network created, but there is only one genesis file content I can use, so which genesis file should I update in this Android project's 4 files? A little confuse here, hope can have your clarify here. Thanks.

lijiachuan (Wed, 23 Sep 2020 13:57:20 GMT):
From that pool configurator code, seems it tries to dump these 4 genesis file content into one cache folder's genesis.txn file, and each time it goes to the exception ``` catch (PoolLedgerConfigExistsException) { // OK } ``` I checked the file name is "/data/user/0/com.osma/cache/genesis.txn", I am not sure whether this is due to there is no such folder or other reason to go to the exception part.

sheru (Wed, 23 Sep 2020 13:59:16 GMT):
By default it uses sovrin-stagging https://github.com/hyperledger/aries-mobileagent-xamarin/blob/cb56d53f4e8a3da45cefa65503960b9e52e71099/src/Osma.Mobile.App/App.xaml.cs#L87

sheru (Wed, 23 Sep 2020 13:59:45 GMT):
You can add your one too.

sheru (Wed, 23 Sep 2020 14:02:07 GMT):
if you are working with android https://github.com/hyperledger/aries-mobileagent-xamarin/blob/cb56d53f4e8a3da45cefa65503960b9e52e71099/src/Osma.Mobile.App.Android/Osma.Mobile.App.Android.csproj#L138

sheru (Wed, 23 Sep 2020 14:02:26 GMT):
You have to add the files in Android assets.

lijiachuan (Wed, 23 Sep 2020 14:02:45 GMT):
ok, this is helpful, but may I know why in this PoolConfigurator.cs, it will dump 4 files' content into one file? If my understanding is correct, only the last genesis file's content will be kept in the genesis.txn file, am I correct?

sheru (Wed, 23 Sep 2020 14:05:47 GMT):
No its add 4 genesis with 4 different genesis file. if you want to add your own Create a file in Assets https://github.com/hyperledger/aries-mobileagent-xamarin/tree/cb56d53f4e8a3da45cefa65503960b9e52e71099/src/Osma.Mobile.App.Android/Assets

sheru (Wed, 23 Sep 2020 14:06:12 GMT):
Then add after https://github.com/hyperledger/aries-mobileagent-xamarin/blob/cb56d53f4e8a3da45cefa65503960b9e52e71099/src/Osma.Mobile.App.Android/Osma.Mobile.App.Android.csproj#L141

sheru (Wed, 23 Sep 2020 14:07:15 GMT):
add new key pair here for your file with a new key name https://github.com/hyperledger/aries-mobileagent-xamarin/blob/cb56d53f4e8a3da45cefa65503960b9e52e71099/src/Osma.Mobile.App/Services/PoolConfigurator.cs#L20

sheru (Wed, 23 Sep 2020 14:07:48 GMT):
Set your genesis one as default one here https://github.com/hyperledger/aries-mobileagent-xamarin/blob/cb56d53f4e8a3da45cefa65503960b9e52e71099/src/Osma.Mobile.App/App.xaml.cs#L87

Which means it keeps writing the same content into this genesis.txn file?

sheru (Wed, 23 Sep 2020 14:14:47 GMT):
This is inside a for loop and the genesis.txn is used as a tempory file.

sheru (Wed, 23 Sep 2020 14:15:11 GMT):
https://github.com/hyperledger/aries-mobileagent-xamarin/blob/cb56d53f4e8a3da45cefa65503960b9e52e71099/src/Osma.Mobile.App/Services/PoolConfigurator.cs#L53

sheru (Wed, 23 Sep 2020 14:16:12 GMT):
before load the next loop it creates the pool configuration. I believe so.

sheru (Wed, 23 Sep 2020 14:16:50 GMT):
@tomislav Need your comment here.:grinning:

lijiachuan (Wed, 23 Sep 2020 14:17:45 GMT):
There are 4 configs defined in the code as below ``` private Dictionary poolConfigs = new Dictionary { { "sovrin-staging", "pool_transactions_sandbox_genesis" }, { "sovrin-live", "pool_transactions_live_genesis" }, { "sovrin-builder", "pool_transactions_builder_genesis" }, { "bcovrin-test", "pool_transactions_bcovrin_test_genesis" } }; ``` So the first time it writes pool_transactions_sandbox_genesis content to the genesis.txn and generate a pool configuration, then it writes pool_transactions_live_genesis content to the genesis.txn and generate a pool configuration, then it writes pool_transactions_builder_genesis content to the genesis.txn and generate a pool configuration, Lastely it writes pool_transactions_bcovrin_test_genesis content to the genesis.txn and generate a pool configuration

sheru (Wed, 23 Sep 2020 14:18:30 GMT):
Exactly.

lijiachuan (Wed, 23 Sep 2020 14:19:20 GMT):
Is this for testing purpose? Or whether we should only keep one genesis here?

sheru (Wed, 23 Sep 2020 14:20:10 GMT):
This is for support multiple ledger in one mobile app.

sheru (Wed, 23 Sep 2020 14:20:50 GMT):
you can change the default pool one at runtime.

lijiachuan (Wed, 23 Sep 2020 14:21:23 GMT):
ok, got it, so maybe it's due to I could not connect to any of these 4 pool from my local, so it failed

lijiachuan (Wed, 23 Sep 2020 14:21:47 GMT):
let me add my own test indy network and genesis

lijiachuan (Wed, 23 Sep 2020 15:03:22 GMT):
hi @sheru , this issue still happen even with my test Indy network's genesis file content, I followed your instruction, added a new genesis file in Android Assets folder, then updated Android's project file with the new asset item, also changed my default pool name in the App.xaml.cs. But I think the problem is it still goes to the exception part with my own test network's genesis file. https://github.com/hyperledger/aries-mobileagent-xamarin/blob/cb56d53f4e8a3da45cefa65503960b9e52e71099/src/Osma.Mobile.App/Services/PoolConfigurator.cs#L56 ``` catch (PoolLedgerConfigExistsException) { // OK } ``` I am not sure what does this "PoolLedgerConfigExistsException" exactly mean, does it mean the genesis file is not usable or the network could not be connected, any thoughts? Thanks.

lijiachuan (Wed, 23 Sep 2020 15:05:17 GMT):
https://github.com/hyperledger/aries-mobileagent-xamarin/blob/cb56d53f4e8a3da45cefa65503960b9e52e71099/src/Osma.Mobile.App/Services/PoolConfigurator.cs#L48 before this line of code, I added one output to know whether the content is the same as my genesis content(`var fileContent = await reader.ReadToEndAsync();`), and it's true, the content is the same, but when create the pool config, it still goes to the exception.

sheru (Wed, 23 Sep 2020 15:07:04 GMT):

hi @sheru and @tomislav , may I have your idea about this "Network subsystem is down" issue? Thanks a lot

Thank you so much The app got through to the review @tomislav

tomislav (Thu, 24 Sep 2020 12:54:14 GMT):
`Network subsystem is down` is not an exception thrown by Aries. It's a communication issue. A quick search indicates this is related to achieving connectivity.

tomislav (Thu, 24 Sep 2020 12:55:12 GMT):
Incredible. Please post a link of the app once it's published

hi @tomislav , I could not figure out what is the issue. I would like to know what is a correct steps/process to learn about how to build up a mobile app with xamarin and aries framework. I see there is one indipendent project https://github.com/hyperledger/aries-mobileagent-xamarin, and there is also one sample folder in the main aries framework dotnet project, which one is a better start point for learning? Kindly advise.

tomislav (Fri, 25 Sep 2020 14:22:51 GMT):
The github repo is the codebase you want to learn off of. The sample was created very early on.

lijiachuan (Sun, 27 Sep 2020 09:08:58 GMT):
I got the root cause for this issue, which is due to `localhost` didn't work in the Android emulator, after I change it to the local IP address of my laptop, then it worked. I am not sure whether that only happened for myself, whether we can add anything into the documents.

hi, I am trying to run the https://github.com/hyperledger/aries-mobileagent-xamarin, I encountered below issue want to get support here, kindly share with your ideas. Thanks a lot. After I click "Create Wallet" button, althought there is one item with "Connected" status, but the loading icon is keeping showing. Then if I clicked that item, in the mediator command window, below error was shown ``` fail: Microsoft.AspNetCore.Diagnostics.DeveloperExceptionPageMiddleware[1] An unhandled exception has occurred while executing the request. Hyperledger.Aries.AriesFrameworkException: Couldn't locate a message handler for type did:sov:BzCbsNYhMrjHiqZDTUASHg;spec/discover-features/1.0/query at Hyperledger.Aries.Agents.AgentBase.ProcessMessage(IAgentContext agentContext, MessageContext messageContext) at Hyperledger.Aries.Agents.AgentBase.ProcessAsync(IAgentContext context, MessageContext messageContext) at Hyperledger.Aries.AspNetCore.AgentMiddleware.Invoke(HttpContext httpContext, IAgentProvider agentProvider) at Microsoft.AspNetCore.Diagnostics.DeveloperExceptionPageMiddleware.Invoke(HttpContext context) ``` And the connection details could not be shown as expected. I am using a VON test Indy network. Does anyone encountered this issue before? THanks.

lijiachuan (Sun, 27 Sep 2020 13:05:54 GMT):
For the mediator project, seems there is no any specific class/function defined, only some initial configurations in Startup.cs, is this correct? So how could this mediator know how to handle different type of messages?

tomislav (Sun, 27 Sep 2020 13:10:08 GMT):
That's correct. Mediator can only handle `forward` messages (from the standards family) and the internal mediator specific ones, which are not standardized

lijiachuan (Sun, 27 Sep 2020 13:11:21 GMT):
ok, so normally the mediator should just looks like what is in this example project, right?

tomislav (Sun, 27 Sep 2020 13:11:24 GMT):
``` protected override void ConfigureHandlers() { AddConnectionHandler(); AddHandler(); AddHandler(); AddHandler(); AddHandler(); } ```

tomislav (Sun, 27 Sep 2020 13:11:54 GMT):
Yes, for the usual case

tomislav (Sun, 27 Sep 2020 13:12:11 GMT):
We should actually add the discovery handler to the default configuration, it doesn't hurt to do this

lijiachuan (Sun, 27 Sep 2020 13:12:13 GMT):
Ok, that's good, we can use one common mediator program

lijiachuan (Sun, 27 Sep 2020 13:12:48 GMT):
yes, that's added in the Startup.cs `app.UseMediatorDiscovery();`

lijiachuan (Sun, 27 Sep 2020 13:13:08 GMT):
But @tomislav, may I have your idea bout the issue I encountered?

tomislav (Sun, 27 Sep 2020 13:13:28 GMT):
no that's different, in the `MediatorAgent` should be `AddDiscoveryHandler()`

tomislav (Sun, 27 Sep 2020 13:14:31 GMT):
I am responding to the issue

tomislav (Sun, 27 Sep 2020 13:14:48 GMT):
The mediator doesn't support discovery messages by defalt

tomislav (Sun, 27 Sep 2020 13:14:56 GMT):
I don't know why the mobile app asks for it

lijiachuan (Sun, 27 Sep 2020 13:15:16 GMT):
https://github.com/hyperledger/aries-mobileagent-xamarin/blob/cb56d53f4e8a3da45cefa65503960b9e52e71099/mediator/Startup.cs#L43

lijiachuan (Sun, 27 Sep 2020 13:15:52 GMT):
In the mediator's Startup.cs, there has one line of `app.UseMediatorDiscovery();`

tomislav (Sun, 27 Sep 2020 13:16:25 GMT):
That line is about something completely different than the issue you're seeing

tomislav (Sun, 27 Sep 2020 13:16:35 GMT):
that's discovery is about well known configuration middleware

tomislav (Sun, 27 Sep 2020 13:16:35 GMT):
https://github.com/hyperledger/aries-framework-dotnet/blob/master/src/Hyperledger.Aries.Routing.Mediator/MediatorDiscoveryMiddleware.cs

tomislav (Sun, 27 Sep 2020 13:16:58 GMT):
you issue is related to the discovery protocol, which is different

tomislav (Sun, 27 Sep 2020 13:17:04 GMT):
just a coincidence on the same name

lijiachuan (Sun, 27 Sep 2020 13:17:22 GMT):
ok

tomislav (Sun, 27 Sep 2020 13:19:39 GMT):
To resolve this issue you can do one of these things: - Either remove the code in AMAX that calls for discovery on pull down - Add Discovery ability to your mediator, but making custom class same as `MediatorAgent` but with `AddDiscoveryHandler()` added. Then register that class `AddMedaitorAgent()`

tomislav (Sun, 27 Sep 2020 13:20:05 GMT):
I'll submit a PR to add this to default config

Hi, I am trying to use my own domain URL to setup the mediator, I changed below line of code to `options.EndpointUri = "http://mydomain.com";` https://github.com/hyperledger/aries-mobileagent-xamarin/blob/cb56d53f4e8a3da45cefa65503960b9e52e71099/mediator/Startup.cs#L23 But after that change and when I use `dotnet run` to start this mediator in my local, when I browse http://localhost:5000/.well-known/agent-configuration, the content is still showing `ServiceEndpoint` is `http://localhost:5000` but is not `http://mydomain.com`. May I know whether this is correct?

hi @tomislav, I would like to continue disucssing about this discovery message issue. In https://github.com/hyperledger/aries-mobileagent-xamarin/blob/cb56d53f4e8a3da45cefa65503960b9e52e71099/src/Osma.Mobile.App/ViewModels/Connections/ConnectionViewModel.cs#L70, it defines `DiscoveryDiscloseMessage` type's variable `protocols`, and use https://github.com/hyperledger/aries-mobileagent-xamarin/blob/cb56d53f4e8a3da45cefa65503960b9e52e71099/src/Osma.Mobile.App/ViewModels/Connections/ConnectionViewModel.cs#L75 to get `protocols` values. And from https://github.com/hyperledger/aries-mobileagent-xamarin/blob/cb56d53f4e8a3da45cefa65503960b9e52e71099/src/Osma.Mobile.App/ViewModels/Connections/ConnectionViewModel.cs#L94 seems it has a special logic to handle the `MessageTypes.TrustPingMessageType`. Is this some special functions for a connection? Do you have any idea about the purpose of this section of codes? Thanks.

I tried to scan a invitation QR code generated from ACA-Py, and click accept button on the mobile, but the connection's status is keeping as `Negotiating`, I am not sure whether this is related to above issue/

tomislav (Sat, 03 Oct 2020 11:40:43 GMT):
This is not a message type that the mediator can process

tomislav (Sat, 03 Oct 2020 11:42:25 GMT):
These are limitations of indy-sdk

tomislav (Sat, 03 Oct 2020 11:43:11 GMT):
Currently, all credential values must be string, so you can encode anything in the credential value, as long as it's serialized to text or json

horacionunez (Sat, 03 Oct 2020 14:17:31 GMT):
thanks

horacionunez (Sat, 03 Oct 2020 16:33:10 GMT):
My understanding is that not all mediators accept the same commands, but if I read you correctly, there is a set of commands that mediators can handle by design, and this one isn't one of them.

tomislav (Sun, 04 Oct 2020 12:59:59 GMT):
That's correct

horacionunez (Sun, 04 Oct 2020 20:06:13 GMT):

lijiachuan (Mon, 05 Oct 2020 15:16:31 GMT):
Hi all, regarding a personal mobile agent scenario, whether one associated mediator agent is efficient to interact with another agent? Is there any other type of role in a mobile agent process. Because I am reading the Edx.Org's training, and there is one "agency" concep introduced there, but I am not sure whether that agency is one required role in a mobile agent process. If anyone can help on this? Thanks.

swcurran (Mon, 05 Oct 2020 15:35:36 GMT):
I'm not sure what your goal is, but Aries is extremely flexible about how to organize agents. All sorts of configurations are possible. For example a mobile agent could use a mediator and agency for one set of connections, and a different combo for other connections. Of course, the more options/variations, the more complexity in managing. But underlying DIDComm makes the actual routing of messages through a whole range of configs really easy.

horacionunez (Mon, 05 Oct 2020 16:32:42 GMT):
hi all, I have been exploring writing my custom agent and I found an interesting case where when I use `ListCredentialsForProofRequestAsync` on a wallet with matching credentials but nothing gets returned.

So only with one mediator is not enough to be able to interact with another agent, correct? For example, if Alice wants to use her mobile agent to interact with Bob's mobile agent, she needs to have one mediator PLUS one agency then she can interact with Bob, or she could interact with Bob only with one mediator.? I am not so clear about this, so hope can make it clarified. Thanks.

swcurran (Mon, 05 Oct 2020 17:35:11 GMT):
Ah...just one mediator is fine. As long as it is addressable on the Internet it can be used.

swcurran (Mon, 05 Oct 2020 17:36:25 GMT):
Often the one mediator IS an agency. It handles many mobile agents. It can't read any messages sent to the mobile agents, but it can recognize to whom the message is for and can forward the message on.

In this specific is implied that before we can make this request we also need to establish a master secret

Would it be too much to ask if I want a few virtual keywords in the framework code? I need to extend a few methods of the default proof service for my use case. Since adding the virtual keywords won't likely to affect anyone else, I would appreciate it if you allow my PR#135.

Kindly advise. Thanks.

TimoGlastra (Wed, 07 Oct 2020 15:36:27 GMT):
ACA-Py expects the `label` field to be present in the invitation. You can do this by either setting the `AgentName` parameter in the agent config (https://github.com/hyperledger/aries-agent-test-harness/blob/master/aries-backchannels/dotnet/server/Startup.cs#L50) or by passing the `MyAlias.Name` parameter in the `InviteConfiguration` when calling `CreateInvitationAsync`. I'm not 100% sure about aries-mobileagent-xamarin, but I think you should add the `AgentName` parameter in `builder.RegisterEdgeAgent` function here: https://github.com/hyperledger/aries-mobileagent-xamarin/blob/master/src/Osma.Mobile.App/App.xaml.cs#L62-L89

lijiachuan (Wed, 07 Oct 2020 16:24:50 GMT):
thanks @TimoGlastra , adding an agent name resolved that error, currently the connection state is `response`, and from the mobile app, it is shown as `negotiating`. I am not sure what is pending to make it as active connection. Do you have any idea?

This was resolved finally after get a new version of Aries routing package, as previous version could not support discovery protocol, so I removed related function which related to trust ping operations, so there is not one trust ping between two entities. After add back the discovery related functions, the connection can become active finally.

Hey Everyone, Is there any process of issue credential without making a connection with the mobile agent. Thanks for the help. Please share the helpful resource or documentation. Thanks

tomislav (Sat, 17 Oct 2020 12:50:26 GMT):
You can issue a credential without a connection, by calling the corresponding methods in the CredentialService that deal specifically with connectionless transport. See this unit test - https://github.com/hyperledger/aries-framework-dotnet/blob/ed219524e99c4fb30ad5529debe9abc6d4dade72/test/Hyperledger.Aries.Tests/Protocols/CredentialTransientTests.cs#L22

tomislav (Sun, 18 Oct 2020 12:57:44 GMT):
Yes, there are many presentation unit tests. The revocation tests do a lot of issuance and verifications.

Hello, I can't seem to find a way to initiate a issue-credential operation from the holder. I am using dotnet libary with the xamarin mobile agent. I am using this RFC https://github.com/hyperledger/aries-rfcs/tree/master/features/0036-issue-credential as my reference when asking this question. The RFC states that there are two ways for Holder to initiate issue-credential protocol: 1) Holder sends proposal 2) Holder sends request There is no method about propose-credential in the ICredentialService interface of the dotnet library and CreateRequestAysnc method states that the credential has to be in the state "offer" in order to create the credential request. My question is this; How can we initiate a issue-credential process from the holder using dotnet library ?

But current version of aries-framework-dotnet(https://github.com/hyperledger/aries-framework-dotnet) in Nuget is 1.4.0. My question is this, can we migrate nuget packages to static libraries ?

Hi, I have the following setup and need help with the issue I'm facing. - Xamarin Forms app for iOS - DotNet mediator - ACA-Py Agent The connection between the mobile app and the ACA-Py agent is established and active. The ACA-Py agent wants to issue a credential to the Mobile agent. Below are the steps being followed. 1) ACA-Py sends a Credential Offer to the Mobile agent 2) The state of the credential in ACA-Py is `offer_sent` 3) The mobile agent gets the offer with the state `Offered` 4) The Mobile agent invokes the below method `credentialService.CreateRequestAsync` 5) The state of the credential in the Mobile agent is changed from `Offered` to `Requested` 6) The state of the credential in the ACA-Py agent remains `offer_sent` *Expected behavior* The state of the credential in the ACA-Py agent should change from `offer_sent` to `request_received` (after step 5), however, it doesn't change *Note*: This seems to work fine when two ACA-Py agents exchange credentials with each other

Hello, I'm working on Credential Revocation. Everything is working fine, am able to Revoke the Credentials and the status changed to '4'. I have two questions. 1) On Issuer side, the Credential Status is 4 (Revoked), but on Holder/Prover side, it's still 3 (Issued). Why? 2) When Verifier Creates a Proof Request, I also added the `Nonrevoked` Time Interval. Like normally, Prover sends a Presentation Proof response, and the credentials verified normally. Why? ``` NonRevoked = new RevocationInterval { From = 0, To = now } ```

Hey @RazaDen There's no dedicated call for the .NET stream. Contributions are welcome - there are no strict guidelines, other than DCO requirement that all commits must be signed. In terms of code contributions, it all depends if you intend to introduce breaking changes, in which case we can discuss a strategy here on the channel.

Hello @tomislav , thanks for your response. I think the best strategy would be for us to sync in a short offline call so that we can avoid duplicate work and generally work out a plan that works for both of us. Would it be ok for me to e-mail you so that we can set this up? I've found your e-mail @ trinsic if that's still valid.

Still I am unable to find the piece of code where it has been initiated. Can anyone help me on this?

Hi All``` Are there are any sample reference code for sending proof from OSMA App ? It would be really helpful if there are any pointers around sending presentation from OSMA APP. Thanks ```

Hi @rangeshsripathi, please check the network with which you are connected from osma.

Arsh-Sandhu (Tue, 02 Feb 2021 06:31:48 GMT):
I believe you are using different networks on the platform from where you offer the credential and on the OSMA app

Hi Arsh-Sandhu , I am using Von-greenlight.bcovrin network , http://dev.greenlight.bcovrin.vonx.io/genesis , I have used the same genesis block to connect Faber agent and Mobile Agent.

I am trying to build each project in the following order: 1) indy-sdk/libindy 2) indy-sdk/cli 3) indy-sdk/experimental/plugins/postgres_storage But the error message is always the same; `error: failed to run custom build command for `libsodium-sys v0.0.16` Caused by: process didn't exit successfully: `C:\Users\anilh\work\one37\postgres-plugin\indy-sdk\libindy\target\debug\build\libsodium-sys-2c407bb769129617\build-script-build` (exit code: 101) --- stdout cargo:rerun-if-env-changed=SODIUM_LIB_DIR cargo:rerun-if-env-changed=SODIUM_STATIC cargo:rerun-if-env-changed=LIBSODIUM_NO_PKG_CONFIG cargo:rerun-if-env-changed=PKG_CONFIG cargo:rerun-if-env-changed=LIBSODIUM_STATIC cargo:rerun-if-env-changed=LIBSODIUM_DYNAMIC cargo:rerun-if-env-changed=PKG_CONFIG_ALL_STATIC cargo:rerun-if-env-changed=PKG_CONFIG_ALL_DYNAMIC cargo:rerun-if-env-changed=PKG_CONFIG_PATH_x86_64-pc-windows-msvc cargo:rerun-if-env-changed=PKG_CONFIG_PATH_x86_64_pc_windows_msvc cargo:rerun-if-env-changed=HOST_PKG_CONFIG_PATH cargo:rerun-if-env-changed=PKG_CONFIG_PATH cargo:rerun-if-env-changed=PKG_CONFIG_LIBDIR_x86_64-pc-windows-msvc cargo:rerun-if-env-changed=PKG_CONFIG_LIBDIR_x86_64_pc_windows_msvc cargo:rerun-if-env-changed=HOST_PKG_CONFIG_LIBDIR cargo:rerun-if-env-changed=PKG_CONFIG_LIBDIR cargo:rerun-if-env-changed=PKG_CONFIG_SYSROOT_DIR_x86_64-pc-windows-msvc cargo:rerun-if-env-changed=PKG_CONFIG_SYSROOT_DIR_x86_64_pc_windows_msvc cargo:rerun-if-env-changed=HOST_PKG_CONFIG_SYSROOT_DIR cargo:rerun-if-env-changed=PKG_CONFIG_SYSROOT_DIR --- stderr thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: "Failed to run `\"pkg-config\" \"--libs\" \"--cflags\" \"libsodium\"`: The system cannot find the file specified.

horacionunez (Thu, 15 Apr 2021 21:00:19 GMT):
@ascatox indy is the library that allows you to manage the wallet. If you are looking to configure the agent that will work over your wallet, this is something akin to a conf file: https://github.com/hyperledger/aries-mobileagent-xamarin/blob/9779eda8bc177f461c32e22fe405b5ec60dc51a3/src/Osma.Mobile.App/App.xaml.cs#L64

If you elaborate more in what you are trying to build I can provide more help

ascatox (Tue, 20 Apr 2021 11:43:08 GMT):
Hi All! I'm exploring the aries mobile xamarin project! I've found in the .indy-client folder a wallet for the Mediator and some EdgeXX wallets for mobile applications connected to the mediator! I suppose that each mobile app has on own wallet. I can't understand the function of a wallet for the mediator.

horacionunez (Tue, 20 Apr 2021 14:25:01 GMT):
hey ascatox, yes, for xamarin project every app is expected to have only one wallet. the mediator is required to power features like mobile notifications.

horacionunez (Tue, 20 Apr 2021 14:25:34 GMT):
If you see the video in the project page you will get a good intro.

horacionunez (Wed, 21 Apr 2021 21:59:37 GMT):
Make sure you have the libindy file linked to the compilation process. I will recommend having a folder for libs right next your project.

sebastian (Fri, 07 May 2021 14:19:02 GMT):
Are you sure you have the required write permissions for the ledger? The IssuerDid must be known on the ledger and must have the required permission (e.g. Endorser)

SahilK 6 (Sat, 08 May 2021 11:38:50 GMT):
Yes. The IssuerDid of the Edge Agent is assigned the role of an `Endorser` on the Ledger. There is an entry for that on the Ledger.

TimoGlastra (Wed, 12 May 2021 05:15:24 GMT):
Is it possible the schema already exists on the ledger?

Mediator Stuck and isn't Updating (sending/receiving messages to mobile agent) 2 Months ago, updated the `Hyperledger.Aries.Routing.Edge` to `1.6.1` from `1.4.0` and last week I noticed that we were getting an error in Presentation Proof, used the older version of agents and were still getting that same error. Noticed, that mediator got stuck and wasn't updating (after every 10 seconds, it route messages to mobile agent from issuer/verifier agent). Now, using `1.4.0` again and Connections are most of time stuck in Negotiating, Credentials in Requested state e.t.c, and all these issues because of the reason that Mediator stuck and isn't routing messages. I only noticed this error in mediator logs few times. ``` fail: Microsoft.AspNetCore.Diagnostics.DeveloperExceptionPageMiddleware[1] An unhandled exception has occurred while executing the request. Microsoft.AspNetCore.Server.Kestrel.Core.BadHttpRequestException: Unexpected end of request content. at Microsoft.AspNetCore.Server.Kestrel.Core.BadHttpRequestException.Throw(RequestRejectionReason reason) at Microsoft.AspNetCore.Server.Kestrel.Core.Internal.Http.Http1ContentLengthMessageBody.ReadAsyncInternal(CancellationToken cancellationToken) at Microsoft.AspNetCore.Server.Kestrel.Core.Internal.Http.HttpRequestStream.ReadAsyncInternal(Memory`1 buffer, CancellationToken cancellationToken) at System.IO.StreamReader.ReadBufferAsync(CancellationToken cancellationToken) at System.IO.StreamReader.ReadToEndAsyncInternal() at Hyperledger.Aries.AspNetCore.AgentMiddleware.Invoke(HttpContext aHttpContext, IAgentProvider aAgentProvider) at Microsoft.AspNetCore.Diagnostics.DeveloperExceptionPageMiddleware.Invoke(HttpContext context) ```

Arsh-Sandhu (Tue, 08 Jun 2021 12:32:13 GMT):
Hi @SahilK 6, ServiceMessageProcessingEventis not published by default when a BasicMessage is received. You have to create a your own AgentMiddleware and process the basic message in OnMessageAsync function

horacionunez (Wed, 16 Jun 2021 17:24:02 GMT):
What do you mean by performance here? Time it takes to complete those flows, or the reliability of supporting them?

horacionunez (Wed, 16 Jun 2021 17:25:15 GMT):
I'm not aware of any benchmark report atm. But isn't hard to setup some code to track this flows in your app.

ankita.p17 (Thu, 17 Jun 2021 07:09:09 GMT):
I'm referring to time it takes to complete the flows. We can have a setup and test but it's good to compare with some benchmark if we have.

horacionunez (Fri, 18 Jun 2021 17:43:36 GMT):
hmm.. from memory... I have seen credentials verified between 5-10 seconds max.

horacionunez (Fri, 18 Jun 2021 17:44:36 GMT):
but I think the latency here has to do more with your infrastructure than with the framework design. the aries framework is a very thin layer on top of .net

I think this is a more general problem with peer dids that currently is not handled by any agent that I'm aware of. If you use public DIDs you can solve the issue, but for peer DIDs you need something like the sync-connection-protocol to update the diddoc https://github.com/hyperledger/aries-rfcs/blob/master/features/0030-sync-connection/README.md

Chances are the image from the .NET agent is sent in a different attribute (attachDecorator) and may not be parsed correctly by Aca-Py. I believe connecting to the .NET agent (Mobile agent-1 connects to Mobile Agent-2) should work fine.

@RounakGhosh , I suggest you check the real-time logs of the below - Connect from one Aca-Py (having a profile image) with another Aca-Py. See the structure of the `ConnectionRequest` - Connect from one Edge Agent (having a profile image) with Aca-Py. See the structure of the `ConnectionRequest` I believe you'll find some differences in the way the profile image URL is sent by the Edge Agent and Aca-Py

hi, Is it possible to add images in schema for identity issuance e.g. passport picture?

swcurran (Fri, 30 Jul 2021 15:49:10 GMT):
Images have been successfully passed, but base64'ing the image. Tricky part is that the parties involved in processing the schema must know it is an image and what to do with it.

SahilK 6 (Thu, 19 Aug 2021 06:41:48 GMT):
@Drilmo , I doubt this can be done. The Mediator Agent cannot read the contents of the payload as the payload is encrypted. All it knows is the source and the recipient of the payload. Hence, you can send a common message for all the events the Mediator Agent receives.

Hi All, I am following OSMA application to present my wallet credentials to the verifier through connectionless way(Connectionless Proof Request). In that i am having the fields like "Predicates and Attributes" and i am trying to present the required attributeCredentials(which contains both predicates and attributes)to the verifier using "CreatePresentationAsync()" aries api. Getting "No valid leaving transitions are permitted from state 'Requested' for trigger 'Request'. Consider ignoring the trigger" exception while presenting my attributes. Could any one help me on this? How should i send predicates into the presenation api? please refer the attached code for better understanding.

We have problems when connecting from findy-agent (Bob) to dotnet-agent (Acme) i.e. when dotnet-agent is creating the invitation and findy-agent is sending the connection request. The dotnet-agent reports that the connection state is invalid: ``` fail: Microsoft.AspNetCore.Server.Kestrel[13] Connection id "0HMC4NQT2RHEA", Request id "0HMC4NQT2RHEA:00000001": An unhandled exception was thrown by the application. Hyperledger.Aries.AriesFrameworkException: Connection state was invalid. Expected 'Negotiating', found 'Invited' at Hyperledger.Aries.Features.DidExchange.DefaultConnectionService.CreateResponseAsync(IAgentContext agentContext, String connectionId) at DotNet.Backchannel.Controllers.ConnectionController.AcceptRequestAsync(OperationBody body) in /src/Controllers/ConnectionController.cs:line 149 at ... ``` Does anyone have idea what would be the cause for this?

Hi, I am trying to create pool and keep getting an IO error while trying to create a pool. I have also verified that the android device has the correct permissions to read write files On Android 30, the application fails. However, with Android 29, it works fine. ``` 9/28/2021 5:59:16 PM - Couldn't create pool config: Hyperledger.Indy.IOException: An IO error occurred. at Hyperledger.Aries.Ledger.DefaultPoolService.Crea tePoolAsync (System.String poolName, System.String genesisFile) [0x00072] in :0 at Osma.Mobile.App. Services.PoolConfigurator.ConfigurePoolsAsync() [0x0023c] in :0 9/28/2021 5:59:16 PM - Couldn't create pool config: Hyperledger.Indy.IOException: An IO error occurred. at Hyperledger.Aries.Ledger.DefaultPoolService.Crea tePoolAsync (System.String poolName, System.String genesis File) [0x00072] in :0 at Osma.Mobile.App. Services.PoolConfigurator.Configure PoolsAsync() [0x0023c] in :0 9/28/2021 5:59:16 PM - Couldn't create pool config: Hyperledger.Indy.IOException: An IO error occurred. at Hyperledger.Aries.Ledger.Default PoolService.Crea tePoolAsync (System.String poolName, System.String genesisFile) [0x00072] in :0 at Osma.Mobile.App. Services.PoolConfigurator.Configure PoolsAsync() ```

Does anybody have issues upgrading the Nuget packages to 1.6.3? It seems like the AspNetCore project requires AspNetCore.Contracts to also be 1.6.3 but the nuget repository only has AspNetCore.Contracts 1.6.2. I don't really want to fork off the repository and add all the projects to mine.
