 JWTKit provides APIs for signing and verifying JSON Web Tokens, as specified by [RFC 7519](https://www.rfc-editor.org/rfc/rfc7519.html). The following features are supported:

 To verify a token, the format of the payload must be known. In this case, we know that the payload is of type `ExamplePayload`. Using this payload, the `JWTKeyCollection` object can process and verify the example JWT, returning its payload on success:
 
 ```swift

 If you don't need to specify custom parsing and serializing but you do need to use a custom JSON Encoder or Decoder, you can use the the `DefaultJWTParser` and `DefaultJWTSerializer` types to create a `JWTKeyCollection` with a custom JSON Encoder and Decoder.
