View Source Charon.TokenFactory.Behaviour behaviour (Charon v1.3.4)

Behaviour for token-signing modules.

Note that the token payload must be returned as a map with string keys on verification. When the payload is serialized as JSON, this happens automatically. However, when Erlang term format is used, this is not the case.
