Examples with ECKey org.gudy.bouncycastle.jce.interfaces.ECKey used on opensource projects

Example 1 with ECKey

use of org.gudy.bouncycastle.jce.interfaces.ECKey in project BiglyBT by BiglySoftware.

the class JDKDSASigner method engineInitVerify.

@Override
protected void engineInitVerify(PublicKey publicKey) throws InvalidKeyException {
    CipherParameters param = null;
    if (publicKey instanceof ECKey) {
        param = ECUtil.generatePublicKeyParameter(publicKey);
    } else if (publicKey instanceof DSAKey) {
        param = DSAUtil.generatePublicKeyParameter(publicKey);
    } else {
        try {

                byte[]  bytes = publicKey.getEncoded();

                publicKey = JDKKeyFactory.createPublicKeyFromDERStream(
                                        new ByteArrayInputStream(bytes));

                if (publicKey instanceof ECKey)
                {
                    param = ECUtil.generatePublicKeyParameter(publicKey);

                }
                else
                {
                */
            throw new InvalidKeyException("can't recognise key type in DSA based signer");
        // }
        } catch (Exception e) {
            throw new InvalidKeyException("can't recognise key type in DSA based signer");
        }
    }
    digest.reset();
    signer.init(false, param);
}

Example 2 with ECKey

use of org.gudy.bouncycastle.jce.interfaces.ECKey in project BiglyBT by BiglySoftware.

the class JDKDSASigner method engineInitSign.

@Override
protected void engineInitSign(PrivateKey privateKey) throws InvalidKeyException {
    CipherParameters param = null;
    if (privateKey instanceof ECKey) {
        param = ECUtil.generatePrivateKeyParameter(privateKey);
    } else {
        param = DSAUtil.generatePrivateKeyParameter(privateKey);
    }
    digest.reset();
    if (random != null) {
        signer.init(true, new ParametersWithRandom(param, random));
    } else {
        signer.init(true, param);
    }
