Simply put, MD5 is no longer strong enough for protecting secrets. It's
just too easy to brute-force. SHA1 is ok for now, but it's days are
numbered as well. I think it would be good to alter SHA1 (or something
stronger) as an alternative to MD5, and I see no reason not to use a
random salt instead of username.


I wonder where you want to store that random salt and how this would add
to the security.


One advantage of a random salt would be that the username can be changed
without having to reset the password at the same time.
