Find out Encryption

[aldente]

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
