private byte[] encryptOrDecrypt(byte[] key, byte[] contents, boolean forEncryption) {

        // Credstash uses standard AES
        BlockCipher engine = new AESFastEngine();

        // Credstash uses CTR mode
        StreamBlockCipher cipher = new SICBlockCipher(engine);

        cipher.init(forEncryption, new ParametersWithIV(new KeyParameter(key), INITIALIZATION_VECTOR));

        byte[] resultBytes = new byte[contents.length];
        int contentsOffset = 0;
        int resultOffset = 0;
        cipher.processBytes(contents, contentsOffset, contents.length, resultBytes, resultOffset);
        return resultBytes;
