[dsr_]

It really doesn't matter how many bits, or what cipher they used. The DRM problem is fundamentally broken:

1. Hand the ciphertext to the opponent.

2. Hand the decryption algorithm to the opponent, embedded in a software or hardware device.

3. Hand the key to the opponent, possibly embedded in the hardware.

4. Ask your opponent to decrypt the ciphertext, view the plaintext, and then kindly not copy the plaintext in any other way.
