OutputStream outputStream = crypto.getCipherOutputStream( fileStream, new Entity("TEST1")); // Write plaintext to it. outputStream.write(plainTextBytes); outputStream.close(); }

FileInputStream fileStream = new FileInputStream(file); Crypto crypto = new Crypto( new SharedPrefsBackedKeyChain(context), new SystemNativeCryptoLibrary()); // Creates an input stream which decrypts the data as // it is read from it.
