Find out Encryption

[aldente]

I don't think so.

Let me explain:

There are several programs by one company, which communicate over the web, and use encryption to protect their data.

One (an Applet) uses simple DES-encryption (encrypted by an PHP-Script), and I already found the key. It does not consist of arbitrary hex-values, converted to ASCII-characters, it's a nice word

It's likely, that the other programs (Win32) use the same key, but obviously different encryption. I may be completely wrong, but I think it's worth a try, before I spend hours with disassembling and analyzing the algorithm.
