ideally the crypt function should be selectable at compile time.  I have
seen MD5 and blowfish in the wild as well.  IIRC, early unix used enigma
cipher.  plaintext may be acceptable for some applications.  (telnet
itself is hardly secure.)

I wonder which besides plaintext is the lowest memory overhead?  (:
