crypt (assuming that's what you're using) uses modified DES to create a hash of the password and a "salt" - a semi-random value that ensures that the encrypted value is unique, or at least very hard to duplicate. If you're really interested, I suggest Applied Cryptography, by Bruce Schneier (http://www.counterpane.com/). Crypto is difficult stuff. -j At 03:33 PM 9/15/98 -0400, you wrote: > >Hello, > >I am tring to learn how the encryption system works... >I gave a passwd of "aabbcc" and wrote the passwd cryption >and then changed it to something else and back again.
