The OP's issue is that the data must be destroyed instantly even in the event of a power failure. Use case scenario: thief breaks in and steals the host, just yanking power cords/etc out, and then pulls the drive and mounts it on another system to recover this data; it is sensitive enough that it must be destroyed immediately by the power failure. Unfortunately, nothing in Windows is designed for that kind of security, and Cygwin has to work around a lot of Windows design flaws to function in general. I've test all of the suggestions I've seen so far with the exception of the cygserver and shared memory, and all of the ones I've tested failed the power failure scenario. I think if the cygserver/shared memory suggestion works, it will be the only available option to prevent the data from default existing on the disc, and due to another of Window's design flaws, may still be written into the page file, though it would be much harder to cleanly extract from the page file than from a normal filesystem file. -- Erik -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
