Interface SM9SigUserKeyGenerator

All Known Subinterfaces:
SM9SigMasterPrivateKey
public interface SM9SigUserKeyGenerator
A master private key capable of the KGC user-key extraction for an identity-based signature scheme: deriving a user's key pair from the user's identity (GM/T 0044.2-2016 for SM9, where the signature private-key generation function identifier hid is applied internally).

      KeyPair generateUserKeyPair(byte[] identity)
      Generate the key pair of the user identified by identity: the private key that signs and the public key a verifier checks against. This derivation is a KGC operation and is deterministic - the same master key and identity always yield the same pair.
      Parameters:
      identity - the user's identity.
      Returns:
      the user's key pair.
