## SoftwareStatementValidator Class

Validates the software\_statement parameter in a client registration request per RFC 7591 Section 2\.3\.
Software statements are signed JWTs issued by a third\-party authority asserting metadata about client software\.

```csharp
public class SoftwareStatementValidator : Abblix.Oidc.Server.Endpoints.DynamicClientManagement.Validation.IClientRegistrationContextValidator
```

Inheritance [System\.Object](https://learn.microsoft.com/en-us/dotnet/api/system.object 'System\.Object') → SoftwareStatementValidator
