I need to be able to store credit card information taken from an online form. I don't need to hang onto the data too long, but I need to use it to set up several accounts with other providers on my client's behalf.
I've read that sending the data via e-mail is a bad idea, and that it's better to store it encryped in a database. My question is how do you do a 2-way encryption for it? I know you can use the MySQL PASSWORD for 1-way, but I'm cluess on the proceedure for 2-way.
Can anyone help with this?
