    Hi and thanks for the reply.

    I realize that but my key is 16 Bytes in length if you take a look at my code which I posted before. I am not encrypting anything, I don't know exactly what happens when I use the command m_objPlusSL1.switchToSL3(keyData) from your library but I suspect it is doing something else since the only thing that I pass to it is my key (128 Bit AES) inside the KeyData instance that comes from your library.

    This is the code that generates the key:

    // Generate AES 128-Bit Key and save to File on first run
    final int keyLength = 128;
    SecureRandom secureRandom = new SecureRandom();
    KeyGenerator keyGenerator = KeyGenerator.getInstance("AES");
    keyGenerator.init(keyLength, secureRandom);
    SecretKey aesKey = keyGenerator.generateKey();*/

    File keyFileBin = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS), "key.bin");
    // Save Key to Disk
    BufferedOutputStream bos = new BufferedOutputStream(new FileOutputStream(keyFileBin));
