Examples with DHPublicKeyParameters org.gudy.bouncycastle.crypto.params.DHPublicKeyParameters used on opensource projects

Example 1 with DHPublicKeyParameters

use of org.gudy.bouncycastle.crypto.params.DHPublicKeyParameters in project BiglyBT by BiglySoftware.

the class DHKeyPairGenerator method generateKeyPair.

@Override
public AsymmetricCipherKeyPair generateKeyPair() {
    BigInteger p, g, x, y;
    int qLength = param.getStrength() - 1;
    DHParameters dhParams = param.getParameters();
    p = dhParams.getP();
    g = dhParams.getG();
    // 
    // calculate the private key
    // 
    x = new BigInteger(qLength, param.getRandom());
    // 
    // calculate the public key.
    // 
    y = g.modPow(x, p);
    return new AsymmetricCipherKeyPair(new DHPublicKeyParameters(y, dhParams), new DHPrivateKeyParameters(x, dhParams));
}

Example 2 with DHPublicKeyParameters

use of org.gudy.bouncycastle.crypto.params.DHPublicKeyParameters in project BiglyBT by BiglySoftware.

the class DHBasicKeyPairGenerator method generateKeyPair.

@Override
public AsymmetricCipherKeyPair generateKeyPair() {
    BigInteger p, g, x, y;
    int qLength = param.getStrength() - 1;
    DHParameters dhParams = param.getParameters();
    p = dhParams.getP();
    g = dhParams.getG();
    // 
    // calculate the private key
    // 
    x = new BigInteger(qLength, param.getRandom());
    // 
    // calculate the public key.
    // 
    y = g.modPow(x, p);
    return new AsymmetricCipherKeyPair(new DHPublicKeyParameters(y, dhParams), new DHPrivateKeyParameters(x, dhParams));
