Encrypting more than user password

For obvious security reasons (if your logic demands it that way) you can encrypt any type of data , just be sure to make data base fields length accordingly. Generally speaking only passwords are encrypted.

You'd obviously need a way of decrypting so if they have access to the database, they can probably see where and how to decrypt that data. I would worry about securing the server/code before trying to encrypt that sort of data, obviously nothing is 100% secure all of the time but seems a bit extreme.

@csuarez Try this http://thinkdiff.net/mysql/encrypt-mysql-data-using-aes-techniques/

Copied from that site:

"Sometimes clients want that the information they collected from the user should be encrypted and stored in database. Data encryption and decryption is a common technique for secured data. In this article I’ll show how could you use mysql’s built in function to encrypt and decrypt data.

Suppose you’ve a table where you want to encrypt user’s name & address. So look below the structure of the table. In this table we will store name and address as encrypted."

thanks @xsmall. I will give this a try.
