org.bouncycastle.jcajce.provider.asymmetric.sm9.KeyPairGeneratorSpi.Sign

Enclosing class:

KeyPairGeneratorSpi

public static class KeyPairGeneratorSpi.Sign
extends KeyPairGenerator

Generator for the SM9 signature master key pair (GM/T 0044.2), registered as KeyPairGenerator.SM9-SIGN. A user's signing key pair is derived from the master private key via SM9SigUserKeyGenerator.generateUserKeyPair(byte[]), the deterministic KGC operation (hid = 0x01).
