Hello, while implementing the JWK EC part of the JOSE draft, I've come across the following question:
draft-ietf-jose-json-web-algorithms-10 "5.2.2. JWK Parameters for Elliptic Curve Private Keys In addition to the members used to represent Elliptic Curve public keys, the following member MUST be present to represent Elliptic Curve private keys:" However an EC private key is fundamentally different from an EC public key, it is just an integer and doesn't have the x and y parameters that an EC public key has. So when representing a EC private key, the x and y members of the public key are not readily available. Was it the intention of the WG that the encoding of the EC private key should include the parameters from the public key?
