Encrypted session BLOB?

... You can even add more fields to the sessions table, so that it is tied to the session ID, if that's what you want ...

Hi Narf,

Sorry to revive this thread but I came across it trying to figure out how to do exactly that. I'm struggling to figure out how to extend the database session driver so I can add a username field which would make it easier to confirm if someone is logged in, among other things. I had hoped to overwrite the write() function.

Is this possible? I've gone through the CI docs but this doesn't seem to be outlined. Any advice would be much appreciated.
