Say for example you have a login and register script which uses the database to store a password. Most people MD5 encrypt the password then add it to the database. If someone can unencrypt that they'll find the password, a way to fix this is by adding something called a salt to the password. A salt is a randomly generated MD5 encrypted string, add that to the database then add the salt to the password then encrypt that, so it's md5($pass + $salt).

This will make it very secure and virtually impossible to unencrypt.

For more info put "php login with salts" in google you should find something.

interesting - thanks for the tip, i gotta try that sometime
