HMACMD5 Class
You should start from here; always start with the documentation.

First of all, why using broken MD5? What's the problem? .NET MD5, as many other cryptography stuff, is a part of official FCL...

This is an extremely bad idea.

You store hashed passwords in the database because you don't want an attacker who compromises your database to be able to read your users' passwords.

But by hashing the password on the client, and sending only the hashed password to the server, you have effectively undone that. Now, an attacker who has access to your database doesn't need to reverse the password hash, because the password hash is the password.

Sure, they can't get the original password and try it on other sites, so you're doing very slightly better than storing passwords in plain text. But they can still authenticate to your site as any user they want, without having to break your password hashing.
