Re: Random String Generation

The method I use is to take their user_id or email and create an HMAC (hashed message authentication code) by hashing it with a secret key on my end. This way the activation link looks like the following: http://mysite.com/activation.php?user_id=petej&ID=ghjghjg367ghjlkj9hjlkj THe activation script takes the user_id they passed in and hashes it with the secret key again. The result should match the ID they passed. Easy and pretty secure. HTH. Pete.
