Proprietary Encryption!

2012-11-27 00:48:27.787505+00 by Dan Lyke 2 comments

Why you don't roll your own encryption. Asher Langton downloads Leaping Brain video file, discovers that player is a Python wrapper around VLC, figures out that he can save unencrypted .MOV from that, further finds that in fact the "BrainTrust™ proprietary video encryption" is that the beginning of each 1K block is XOR'd with "RANDOM_STRING".

I roll my own encryption, but it's for relatively low security stuff, because dealing with PGP is an effing pain. And I'd never pull anything as half-assed as what that guy did. I'm not saying exactly what I use, but I'll just say I haven't been seriously into recreational cryptography since I was ten years old for nothing.

[Edited to make it clear that I can do way better than the XOR fool, not that I can do way better than PGP. If I were THAT good I'd be doing crypto for a living.]

Article 3 days from now: Asher Langton is charged under the DMCA for circumventing encryption.
