Re: Giving a device access to EFS (Encrypting File System)

Clarify what you mean by "the device API" ?
Do you mean a raw read that bypasses NTFS (which implements
EFS and going through which should be in context of account that
the process is running within).

Hi,

I am developing an application that uses encrypted files which are
encrypted under EFS. My application can directly open the files fine,
but when I call the device API function to open the file, the device
cannot read the contents.

I think the device cannot open the file because it doesn't have the
rights to access EFS encrypted files.

I did some research and found that all users need to have the correct
certificate and private key inorder to read the contents of EFS
encrypted files. I assume that a device would need the same to read
encrypted files.

I need to know how to assign a device (or its driver) the correct
certificate and private key.

Can someone please tell me how I can go about doing this? Or if I'm
completely off, can someone point me in the right direction?

Thanks in advance,
Kevin
