JwtDecoder (spring-security-docs 5.7.7 API)

All Known Implementing Classes:

NimbusJwtDecoder, NimbusJwtDecoderJwkSupport, SupplierJwtDecoder

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
```
@FunctionalInterface
public interface JwtDecoder
```
Implementations of this interface are responsible for "decoding" a JSON Web Token (JWT) from it's compact claims representation format to a Jwt.
JWTs may be represented using the JWS Compact Serialization format for a JSON Web Signature (JWS) structure or JWE Compact Serialization format for a JSON Web Encryption (JWE) structure. Therefore, implementors are responsible for verifying a JWS and/or decrypting a JWE.
