## SignedResponseAlgorithmsValidator Class

Validates the algorithms a client requests for tokens this server signs:
`id_token_signed_response_alg` and `userinfo_signed_response_alg` \(OIDC DCR 1\.0 §2\), and
`authorization_signed_response_alg` \(JARM §3\)\. Each must appear in the server's set of supported
signing algorithms; in addition, JARM §3 forbids `none` for the authorization response\.

```csharp
public class SignedResponseAlgorithmsValidator : Abblix.Oidc.Server.Endpoints.DynamicClientManagement.Validation.SyncClientRegistrationContextValidator
```

### Constructors

## SignedResponseAlgorithmsValidator\(IJwtAlgorithmsProvider\) Constructor {#Abblix.Oidc.Server.Endpoints.DynamicClientManagement.Validation.SignedResponseAlgorithmsValidator.SignedResponseAlgorithmsValidator(Abblix.Oidc.Server.Endpoints.Configuration.Interfaces.IJwtAlgorithmsProvider)}

Validates the algorithms a client requests for tokens this server signs:
`id_token_signed_response_alg` and `userinfo_signed_response_alg` \(OIDC DCR 1\.0 §2\), and
`authorization_signed_response_alg` \(JARM §3\)\. Each must appear in the server's set of supported
signing algorithms; in addition, JARM §3 forbids `none` for the authorization response\.

```csharp
public SignedResponseAlgorithmsValidator(Abblix.Oidc.Server.Endpoints.Configuration.Interfaces.IJwtAlgorithmsProvider jwtAlgorithms);
```
#### Parameters

###### `jwtAlgorithms` [IJwtAlgorithmsProvider](https://www.abblix.com/en/docs/api/abblix-oidc-server/Abblix.Oidc.Server.Endpoints.Configuration.Interfaces.IJwtAlgorithmsProvider 'Abblix\.Oidc\.Server\.Endpoints\.Configuration\.Interfaces\.IJwtAlgorithmsProvider') {#Abblix.Oidc.Server.Endpoints.DynamicClientManagement.Validation.SignedResponseAlgorithmsValidator.SignedResponseAlgorithmsValidator(Abblix.Oidc.Server.Endpoints.Configuration.Interfaces.IJwtAlgorithmsProvider).jwtAlgorithms}

Source of supported signing algorithms for outbound tokens\. The same
            provider feeds the discovery document, so DCR accepts exactly what the server advertises —
            in particular HS\* stays rejected here for the same key\-availability reason it is not
            advertised \(client secrets are stored hashed and cannot serve as HMAC keys\)\.
