Hmmm...That might kind of work for protecting transcient data. Then
again, I presume that you're generating the key using one of the random
functions in PHP. Knowing the time when the key is generated (from the
server log) and the process id, an attacker would be able to narrow the
range of possible keys considerably. We're assuming here the server is
properly set up and the attacker only has access to the web server
account.
