Cryptography in the Authz Server flow that could be done with Zenroom

[andrea-dintino]

Currently from the JOSE, we use

SignJWT(a lot of stuff.... .sign(privateKey);)
jwtVerify(dpop, publicKey)

They both use ES256 as curve/algo, so they could be replaces with a zencode_exec (dpopVerify, { data, keys}) (the SignJWT would require a Zencode doing some formating or doing object.sign = zencode_exec()
