How to Sign a jwt token with just a string and not publicKey and privateKey

You can't (at least not for a RSA family algorithms). I think the documentation is pretty explicit saying that the key needs to be one of (1) a raw key (*rsa.PrivateKey, et al), (2) a crypto.Signer, or (3) a jwk.Key

https://pkg.go.dev/github.com/lestrrat-go/jwx/[email protected]/jws#WithKey

token, err := jwt.Sign(t, jwt.WithKey(signatureType, s.Conf.Jwt.Secret))

I can only guess what's store in the s.Conf.Jwt.Secret variable, but I have a feeling you are copying from an example that uses a symmetric algorithm, such as HS256. In that case, the raw key could be a []byte, which is the "raw" version of a jwk.SymmetricKey

Thank you. I made a mistake using a wrong algo.
