kc9ddi Posted December 3, 2006 Share Posted December 3, 2006 I'm working on a PHP script that stores some info in a mysql table. I'm wondering about methods for encrypting data in certain columns, but allowing it to be decrypted by authorized users (eg, social security numbers). MD5 and such are all one-way encryption, and I'm looking for something that can also be decrypted. Is there a popular tool/method for this?

fenway Posted December 3, 2006 Share Posted December 3, 2006 All strong encryption schemes utilize a secret key that's only available from somewhere secure. Quote Link to comment Share on other sites More sharing options...
