[guardian-dev] idea for managing multiple virtual disks in IOCipher

[Hans of Guardian]

I just had a thought for a simple way to manage multiple virtual disks in the same process when using IOCipher.  If there was just a ChangeVirtualDisk() method that you give the path too, that would change the context of any following IOCipher calls.  It would not work for copying between to the two virtual disks, but we could provide a special method for that too.

This could be useful to support temporary virtual disks to do things like secure scratch space for things that need to be rapidly deleted.
