On recent wanderings around the internet I have noticed a few postings from people concerned about sensitive data being swapped to disk when running apps on a windows platform. Are there any safeguards in place which can prevent this from occuring in SecureBlackboxPGP? I would rather avoid using any kernel32 api functions on a server which runs other processes..!

Kind Regards,

Security is as weak as it's weakest link. Memory being swapped to disk (to a pagefile) is far from a weakest link. If the server is running some harmful process, such server is in HUGE trouble by itself, with or without swapping.

Thanks again for a very quick reply - I am guessing that is a no then.
I agree, it's certainly not the weakest point of course.
Mitigation of possible security issues is generally a good idea though if possible. I figure playing with win memory management at a reasonably low level is probably not worth the very slight risk involved with some secure data somehow ending up in the swapfile and somehow falling into the wrong hands!
I suppose if need be the whole disk could be encrypted anyway.

Cheers again,
