All Implemented Interfaces:

Serializable, Comparable<Identifier>, net.minidev.json.JSONAware
```
@Immutable
public final class Nonce
extends Identifier
```
Nonce. This is a random, unique string value to associate a user-session with an ID Token and to mitigate replay attacks.
Example generation of a nonce with eight random mixed-case alphanumeric characters:
```
 Nonce nonce = new Nonce(8);
 
```
