This is a logical fallacy. It is called circular reasoning. I need a key to decrypt a key. I still have to store that secondary key somewhere, or the system will have to regenerate it. Regenerate means I can see it in the source. Storage means it is a sitting duck, unencrypted.

Unless your point was simply that you shouldn't keep them around indefinitely in retrievable form -- and I don't. I don't encrypt them though, just delete them at regular intervals, as the session times out.
