This is also somewhat OS dependant.  The *BSDs for example have a crypt()
that can handle DES, MD5, and Blowfish.  I'm successfully using Blowfish
(accounts were system account users from OpenBSD) after making the
pw_passwd field larger in mysql.

Some OSes have a config file for crypt() that will set the default
encryption method.  "man 3 crypt" should give some indication of how your
OS will behave.
