Re: Storing sensitive data

The usual way of doing this is by not storing the password, but
instead an MD5 representation of the password:

INSERT INTO users (username, password) VALUES ('kevin', MD5('mypassword'))

SELECT * FROM users WHERE username='kevin' AND password=MD5('mypassword');

This does mean that you won't know what your users passwords are, and
that a user can't be reminded of their password, only have it changed,
but these are usually un-important side effects.

Hope this helps,

Neil.
