The DES scheme used
For whatever reason, Bemani decided that IDs should be encrypted. Thankfully however they used triple DES, which
almost certainly has an existing implementation in your language of choice. It is triple DES, in CBC mode, with
- a totally null IV. The key is quite easy to find if you hit the right binaries with
- strings. Alternatively, check the source of this page. The key
- contains characters that are all within the ASCII range. Before we can use it with DES, the value of every byte
- needs doubled. This was presumably done to give the values more range, but I sincerely doubt it adds any
- additional security.

I'm curious how Bemani implemented this in their own code!
Curiosity is a great thing. Unfortunately, this is code that is implement within the game specific DLL files.
