Hmmm... I'm new to all this DES stuff...But do have a general
purpose DES encripter that I can run in a batch file!!
After reading all theas messeges about trying to brake
DES....well has anyone ever thought that only a dum &^%$ would only
encript a file/text only ONCE?!?!?!?!?!?!?!?!?!?!?
Of cores if you have than I must not be reading very well and I
will be more perseptive in the fucher!
