What's the difference between compression and encryption? Correct me if I'm wrong, in compression we lose something, like in image compression and audio compression, but in encryption, we don't. One sure protection againts evil hackers is encryption (?), but what if that evil hacker deletes the ciphertext file and the plain text file (that is assuming the evil hacker just deletes every file he wants to delete). ---at least he/she didn't read/saw the file. =============================================================================== You give the words you have spoken, it is not lended and are not taken back. It is like what The Corrs sung "...you're forgiven not forgotten...." bbt@mudspring.uplb.edu.ph bbt@peak-two.uplb.edu.ph metaphone@altavista.net
