File system Filter Driver Awareness Question-Please Help
Posted by Shalini on April 2nd, 2004


Hello All
Supppose one writes a Encryption file system filter driver which does On the
fly encryption and decryption will it bother with the OS booting.
For example if some of the OS files are encrypted then the OS will not be
able to boot right. At least the files till the filter driver loads must not
be encrypted. How to do such a check condition. Like what are ll the files
which shud not get encrypted or how to avoid those files getting
encrypted.?? Or is there some other way?
Waiting for ur suggestions
Regards
Shal

First this is better answered on the ntfsd forum at http://www.osronline.com
Basically encrypting everything is a stupid idea, the files needed prior to
your driver being active will change dynamically, trying to get this right
in a filter driver is a stupid idea. Go ask for suggestions at ntfsd
