Changing MD5 passwords

Hi all,

I have a membeship site that automatically issued users with MD5 encrypted passwords. Users can request a new password but they can't set their own.

Any ideas on the best way to let a user enter a plain text password into a form and have ir stored in MySQL with MD5 enctiption?

The form could store the user-password string in a variable, which you could then encode using the MD5 function [php.net] before altering it in the database, and then compare them as you already must do when users login. Or am I missing something obvious? :\

That shouldn't be a problem.

Just make sure that the person changing the password is actually the user who owns the account!

Can be done in 2 ways in my opinion:

1. User also enters old password for verification.
2. User also enters some verification-code he got sent via email.

note that point 2 you can also accomplish by using the ability to give them a auto-generated password (wich you allready have). Users can then use point 1 using that generated password to effectively get point 2 :).

get the idea?
