Just stating the obvious here though; if the web server is genuinely
untrusted, then logically none of this can be secured anyway.

An attacker at the web server is a classic MITM. All they need to do is
remove the client side auth code as it passes on the way out to the
client, and then they will always receive a clear-text password back
from the client. POW!

If you don't trust the server, then a web delivery mechanism probably
isn't the right architecture at all.
