getKeyFromToken
getKeyFromToken(token: String): String typeMethod;
The getKeyFromToken method of the JadeJsonWebKeySetReader class parses a JSON Web Token for the issuer (iss) claim, uses it to request a JSON Web Key Set from the well‑known endpoint of that issuer, then returns the public key of the first X5c certificate in that JSON Web Key Set with the key identifier (kid) claim of the token specified in the token parameter.
