Not crypt() the library routine--crypt the program. If you have files encrypted using the crypt program, they can be attacked easily (i.e. by someone without any knowledge of codebreaking) using Bob Baldwin's "Crypt Breaker's Workbench" (cbw). Bob's fdes package speeds up the crypt() routine by a factor of 20-100, so brute force attacks become more attractive (e.g. throwing /usr/dict/words at the password file) but, in general, crypt() is not know to have been broken.
