Example 1 with XMSSKeyGenerationParameters

use of com.github.zhenwei.core.pqc.crypto.xmss.XMSSKeyGenerationParameters in project LinLong-Java by zhenwei1108.

the class XMSSKeyPairGeneratorSpi method generateKeyPair.

public KeyPair generateKeyPair() {
    if (!initialised) {
        param = new XMSSKeyGenerationParameters(new XMSSParameters(10, new SHA512Digest()), random);
        engine.init(param);
        initialised = true;
    }
    AsymmetricCipherKeyPair pair = engine.generateKeyPair();
    XMSSPublicKeyParameters pub = (XMSSPublicKeyParameters) pair.getPublic();
    XMSSPrivateKeyParameters priv = (XMSSPrivateKeyParameters) pair.getPrivate();
    return new KeyPair(new BCXMSSPublicKey(treeDigest, pub), new BCXMSSPrivateKey(treeDigest, priv));
}
