Encryption Challenge

[Tiberius]

What method of encryption is being used?

Not sure I should say really. The whole point is that someone trying to access a users protected media files has as hard a time as possible..

Sure, but the first rule of security is to assume that an attacker knows as much about your system as possible, since they can always figure it out in the end. The point of a secure system is that it is secure even if the attacker knows how it works (since the real security is in the password / key). This is why the most widely used encryption methods are standardised and the source code available for all.

BTW, the song is Blondie - Picture This.

Edit: If you really can't tell me the encryption method, can you at least let me know if it is standard, or one of your own making?
