protected ParametersWithIV createDecryptionParameters(String password, String salt, byte[] iv) {

    byte[] passwordBytes = password.getBytes(Charsets.UTF_8);
    byte[] saltBytes = salt.getBytes(Charsets.UTF_8);

    PKCS5S1ParametersGenerator keyGenerator = new PKCS5S1ParametersGenerator(new SHA512Digest());
    keyGenerator.init(passwordBytes, saltBytes, PBE_ITERATION_COUNT);

    KeyParameter params = (KeyParameter) keyGenerator.generateDerivedParameters(KEY_SIZE);

    return new ParametersWithIV(params, iv);
