Example 11 with AsymmetricCipherKeyPair

use of org.bouncycastle.crypto.AsymmetricCipherKeyPair in project Skein3Fish by wernerd.

the class DHKeyPairGenerator method generateKeyPair.

public AsymmetricCipherKeyPair generateKeyPair() {
    DHKeyGeneratorHelper helper = DHKeyGeneratorHelper.INSTANCE;
    DHParameters dhp = param.getParameters();
    BigInteger x = helper.calculatePrivate(dhp, param.getRandom());
    BigInteger y = helper.calculatePublic(dhp, x);
    return new AsymmetricCipherKeyPair(new DHPublicKeyParameters(y, dhp), new DHPrivateKeyParameters(x, dhp));
}

Example 12 with AsymmetricCipherKeyPair
