## AuthenticationRequestIdGenerator Class

Generates a unique authentication request ID using a cryptographically secure random number generator\.
This ID is encoded for safe use in URLs and is typically used in backchannel authentication flows\.

```csharp
public class AuthenticationRequestIdGenerator : Abblix.Oidc.Server.Features.BackChannelAuthentication.Interfaces.IAuthenticationRequestIdGenerator
```
