### [Abblix\.SecurityEvents\.Subjects](https://www.abblix.com/en/docs/api/abblix-securityevents/Abblix.SecurityEvents.Subjects 'Abblix\.SecurityEvents\.Subjects')

## IssSubSubject Class

Identifies a subject by a pair of issuer and subject values, the way an OpenID Connect ID token
identifies its subject through the "iss" and "sub" claims \(RFC 9493 Section 3\.2\.3\)\.

```csharp
public sealed class IssSubSubject : Abblix.SecurityEvents.Subjects.SubjectIdentifier
```

Inheritance [System\.Object](https://learn.microsoft.com/en-us/dotnet/api/system.object 'System\.Object') → [SubjectIdentifier](https://www.abblix.com/en/docs/api/abblix-securityevents/Abblix.SecurityEvents.Subjects.SubjectIdentifier 'Abblix\.SecurityEvents\.Subjects\.SubjectIdentifier') → IssSubSubject

### Remarks
When this identifier sits in a JWT's "sub\_id" claim, its [Issuer](https://www.abblix.com/en/docs/api/abblix-securityevents/Abblix.SecurityEvents.Subjects.IssSubSubject#Abblix.SecurityEvents.Subjects.IssSubSubject.Issuer 'Abblix\.SecurityEvents\.Subjects\.IssSubSubject\.Issuer') and
[Subject](https://www.abblix.com/en/docs/api/abblix-securityevents/Abblix.SecurityEvents.Subjects.IssSubSubject#Abblix.SecurityEvents.Subjects.IssSubSubject.Subject 'Abblix\.SecurityEvents\.Subjects\.IssSubSubject\.Subject') members MAY differ from the JWT's own "iss" and "sub" claims
\(RFC 9493 Section 4\.2\): that is how a party names a subject by an identity its counterparty
already understands rather than by its own local one\.
### Constructors

## IssSubSubject\(string, string\) Constructor {#Abblix.SecurityEvents.Subjects.IssSubSubject.IssSubSubject(string,string)}
