Question

I am working on an app which needs encryption of video files which is working quite well.But the method I am using to decrypt returns the video as in Byte array. So is there anyway that I can play the video using that array without creating a new file.

My method decryption:

  private static byte[] decrypt(byte[] raw, byte[] encrypted) throws EncrypterException {
SecretKeySpec skeySpec = new SecretKeySpec(raw, "AES");
try {
    final Cipher cipher = Cipher.getInstance("AES");
    cipher.init(Cipher.DECRYPT_MODE, skeySpec);

    return cipher.doFinal(encrypted);

} catch (Exception e) {
    throw new EncrypterException(e);
}
}

Please help me I am stuck here ?

Answer 1

How do you usually play video? You send InputStrem instance to player.
So you ByteArrayInputStream that wraps your byte array and send it to the player.
