Decoder
Here you can find a simple decoder for JSON Proof Tokens.
Description
Rust library implementing the new JOSE Working Group drafts:
The specification work for this can be found here.
Supported Features
JSON Web Keys (JWK)
JWK is defined in RFC 7517.
NOTE: To represent BLS keys this implementation refers to draft-ietf-cose-bls-key-representations-05.
JWKs are currently used in the proof generation and verification of JWPs.
The tables below represent which kty and crv are supported at momement.

JSON Web Proof Algorithms
The supported algorithm are defined in in the JPA specification.
NOTE: Keep in mind that these specifications are in the early stages, and there is a high likelihood that they will undergo significant changes in the future.
