auto_increment Start over/Password encryption

[Zoud]

Ok, I have two issues.

First of all, how am I to start over the auto_increment values?
For example, I delete someone (id=24) from my DB for breaking a rule, and then the next person that gets inserted into the DB takes his place as #24, instead of #25.

And second, how do I encrypt passwords inserted into the DB for the users protection?
Should be self explainitory.

I'm using phpMyAdmin, if that helps.

Do you want your auto-increment to automatically change.. or just a one time thing? if one time

//ALTER TABLE table AUTO_INCREMENT = value

You can use MD5 hashing, although not the best.

             $pass = md5($pass);

Thank you!
About the md5, you say it's not the best. Is there a better way then?

There are other hashing algorithms that are less "vulnerable", but a salt and some common-sense will be probably be enough.
