Say I own a digital copy of a copyrighted movie. Is it legal for me to encrypt it with say, AES, and share it to the Internet so anyone could download the encrypted copy?
It actually breaks down to these 4 situations:
- Is it legal if I don't share the decryption key to anyone?
- Is it legal if I share the decryption key privately to someone who also owns the same copy?
- Is it legal if I share the decryption key privately to someone who doesn't own the copy?
- Is it legal if I share the decryption key publicly online?
If in any of the above situations it is not legal, which party/parties is/are liable?
Edit: Additional question: How does the above 4 situations apply to the content that is not owned by you, say a video "illegally" downloaded from YouTube.
