It's different..

An admin with informatic skills and with an innocent mind would like to protect users against another bad admin..

A solution for that is to don't store the key to decrypt..

The hack encodes the PM's, and decodes them when received.

It has no real logic, but it was requested by a member, so I created it.

I believe he gave an explenation why he found it usefull, check the thread out. (link in first poist).

Is there any chance of a port of this to 3.5.x please?

I need to stop the designers/hosts/admins ability to access them in the database. :)

This doesn't actually work like it needs to, its not feature complete nor secure.

Really? ah well, that's a shame.

I would say this hack is fairly secure until someone discovers this thread, like with many vb hacks ;)
