Find out Encryption

Hello!

Is there any little tool, to testout different Encryptions?

I have an encoded string, and I (guess I) know the key.

The only problem is: I don't know the encryption.

I'm just sure its not DES, but it could be 3DES, AES, or whatever,
so a little Tool, where you can enter crypted data,
key, and see output, would be nice.

Does anything like that exist?

Otherwise I would have to implement every encryption into a test-program and compile it

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.

Yes, try KANAL plugin for PEiD.
However, it works differently than you expected. It scans the file for known constants, strings etc. - thus identifying the algorithm. No encryption/decryption takes place.
