How to parse JWT Header fields?

[schuerg]

It seems that the jwt.Parse() function only decodes the JWT payload but not the JWT header fields like alg, typ and kid.

So how to parse a given JWT in compact base64 form and get the header fields? Espacially the kid value?

@schuerg I'm going to take a wild guess, but I think you are confusing JWT and JWS. JWT may arrive to you in signed format, but at that point it's a JWS message. Header fields like alg and kid only exist in the JWS message. So if you want to manually do something with the JWS headers, you should be looking at jws.Parse
