I'm looking for recommendations on a 2 way encryption algorithm that I can use for temporarily storing personal data in an online db.
Most shopping carts use RC4 for encrypting CC numbers but I've read that WEP uses RC4 and there are some new algorithms that can crack WEP in seconds.
Is there anything better than RC4 that I can use for this highly modified snitz based site? I've been thinking about ways of keeping the key offline too. Could I drop a cookie onto selected users machines that holds this months key. Could I use a form of RSA keytag that is set to change each month?
Most of the stuff out there is either component or .NET based, but encryption opens up a whole can of worms on its own. This is an interesting article though
