Also, you could use something like:


And do your hashing in javascript in the browser.  Basically you want to
hook onClick/onSubmit/whatever for your login form, and hash the contents of
the passwd field before doing the actual submission, using a javascript sha1
(or other algorithm of your choosing).

Its much safer from a security standpoint to hash at the browser, as this
prevents the user's cleartext password from being sent over the wire at all,
and keeps your code/logs/employees from ever having a chance at knowledge of
the actual password.
