Hey, I was wondering if someone out there could provide some
suggestions. Here is the situation. I have a client that wants to
store CC numbers in the database and mannually process it themselves
on the CC terminal. We have php/mysql available to us. Here are a
couple suggestions I have come up with so far, but am not pleased with
any of them:
1) encrypt CC in database with key from the code when user checksout.
Then retrieve it later from key in code or having admin mannually type
in pw.
Problem: if the code is comprimised so is the database. Not good.
2) create a separate php file that contains the key using zend
encoder. Then call this key from the php code when encrypting and
decrypting db.
Seems resonable - but then we're relying on 3rd party solution.
3) Any others???????
