I’d like to create an encrypted messaging system for use with coaching clients that would work both for 1:1 interactions with my clients or between clients in a BuddyPress site. I’m thinking that a unique salt value could be generated from the user’s account creation informaiton, and that I’d call Mcrypt to encrypt data in a Pre-save Helper. I’d retrieve the user’s salt value and decrypt the message on retrieval.
Am I on the right track? And has anyone done anything at all similar in Pods?
