The "PHPlib" package for PHP provides a challenge-response
authentication scheme where the browser runs a javascript function to
hash the user-supplied password value before sending it as form data.
If javascript is disabled or not available, the clear-text password is
sent instead and the value hashed at the server to match against the
stored value.
