im working on a website where the users can connect with iphone to some functions of it by using a sha1 encrypted password. In other words the plain password of wordpress encrypted in sha1.
In the past i did the silly thing of editing the core files of wordpress to get the password when the user register and save that password in sha1 on the wp_users table.
Of course my client updated wordpress and all the functions were lost. Yeah im stupid, im not sure what i was thinking that day.
There is any way to hook to the register function to get the password , encrypt it in sha1 format and storeit in the database from the functions.php file of my theme?
Any ideas?

Method 1
Have a look at Pluggable Functions in /wp-includes/pluggable.php. You can safely replace the password generating/checking functions with your own.
Method 2
You can hook into wp_check_password(), which does this at end:
return apply_filters('check_password', $check, $password, $hash, $user_id);
If $check is true then $password is current valid pass for $user_id.
Note that this will only work next time specific user logins. You can’t just retrieve plan text passwords for all accounts.
