* configurations, extract payloads from tokens, and renew expired tokens.
* <p>
* <b>Token Creation:</b>

* <b>Token Extraction:</b>
* The interface includes methods to extract payload information from a given

* <b>Token Renewal:</b>
* The interface also offers methods for token renewal. Clients can renew an
