I am pondering the possibility of encrypting/decrypting some fields
in a SQLite backend on-the-fly.
The point of the message is not security, I know that’s broken, but
whether there’s a technique that provides on-the-fly save/read
filters. Of course the solution would need to work transparently in
would do the right thing if title was an encrypted field.
I see in the documentation of ActiveRecord::Callbacks there’s a
before_save callback that looks like going in the right direction,
but I don’t see the symmetric after_(read|find). Any ideas?
