    Credit Card Encryption

    HI All,

    I want to encrypt Credit Card numbers entered on the site and store the encrypted numbers to the database.

    There are many alogorithms of encryption available, like DES, AES, etc which one is the best to use and what is the best way to store my key, should i be storing in a seperate web server, or in db, the performance criteria of the retrival of key and decrypting process also matters

    I have two servers available to opt for so how can best design the encryption methodology so that it becomes hard for intruder to crack..

    If some one can throw some light on the best way to do it..

    Thanks in advance.

    Anand
