ok so best crypt should be the way to head. BUT what about the key process (RSA/diffie) i know that's independent. CAn that process be found somewhere else, I mean the public private key thing was really practical.

Ow and about the HDD space, the temp folder that corresponds to the account is use (under "document and settings") so that would be
c:\documents and settings\username\local settings\temp
is f**king massive !! Like > 300megs how can I get it cleared auto, or put a limit to it.

And know that I think of it, anyone know where the environmment variables are stored such as where to look for temp, user settings "my document", start menu /etc
That would allow me to make window point to another HDD (more space to breath).
(looked in the registry but nothing found :-(
