Examples with DSAKeyGenerationParameters org.bouncycastle.crypto.params.DSAKeyGenerationParameters used on opensource projects

Example 1 with DSAKeyGenerationParameters

use of org.bouncycastle.crypto.params.DSAKeyGenerationParameters in project robovm by robovm.

the class KeyPairGeneratorSpi method generateKeyPair.

public KeyPair generateKeyPair() {
    if (!initialised) {
        DSAParametersGenerator pGen = new DSAParametersGenerator();
        pGen.init(strength, certainty, random);
        param = new DSAKeyGenerationParameters(random, pGen.generateParameters());
        engine.init(param);
        initialised = true;
    }
    AsymmetricCipherKeyPair pair = engine.generateKeyPair();
    DSAPublicKeyParameters pub = (DSAPublicKeyParameters) pair.getPublic();
    DSAPrivateKeyParameters priv = (DSAPrivateKeyParameters) pair.getPrivate();
    return new KeyPair(new BCDSAPublicKey(pub), new BCDSAPrivateKey(priv));
}

Example 2 with DSAKeyGenerationParameters

use of org.bouncycastle.crypto.params.DSAKeyGenerationParameters in project robovm by robovm.

the class KeyPairGeneratorSpi method initialize.

public void initialize(AlgorithmParameterSpec params, SecureRandom random) throws InvalidAlgorithmParameterException {
    if (!(params instanceof DSAParameterSpec)) {
        throw new InvalidAlgorithmParameterException("parameter object not a DSAParameterSpec");
    }
    DSAParameterSpec dsaParams = (DSAParameterSpec) params;
    param = new DSAKeyGenerationParameters(random, new DSAParameters(dsaParams.getP(), dsaParams.getQ(), dsaParams.getG()));
    engine.init(param);
    initialised = true;
