And, within a few days, the open source folks have reverse engineered it. The presence of "magic numbers" in the algorithm makes one assume that this was intended as more than a simple hash integrity check, but the brief time required to find them leads one to believe the mechanism was not a very effective protection (though it isn't even clear what it was intended to protect against.) http://ipodminusitunes.blogspot.com/2007/09/weve-won.html Perry --------------------------------------------------------------------- The Cryptography Mailing List Unsubscribe by sending "unsubscribe cryptography" to [EMAIL PROTECTED]
