Examples with PKCS1Encoding org.bouncycastle.crypto.encodings.PKCS1Encoding used on opensource projects

Example 1 with PKCS1Encoding

use of org.bouncycastle.crypto.encodings.PKCS1Encoding in project faf-java-server by FAForever.

the class UniqueIdServiceTest method rsaEncrypt.

private static byte[] rsaEncrypt(byte[] encryptedData, CipherParameters privateKey) throws IOException, InvalidCipherTextException {
    AsymmetricBlockCipher engine = new PKCS1Encoding(new RSAEngine());
    engine.init(true, privateKey);
    return engine.processBlock(encryptedData, 0, encryptedData.length);
}

Example 2 with PKCS1Encoding

use of org.bouncycastle.crypto.encodings.PKCS1Encoding in project 360-Engine-for-Android by 360.

the class RSAEncryptionUtils method rsa.

/**
 * Encrypts or Decrypts bytes with the given RSA Public or Private Key.
 *
 * @param encrypt true for encrypt, false for decrypt.
 * @param key the RSA Public or Private Key.
 * @param data the data to encrypt or decrypt.
 * @return the encrypted or decrypted data.
