EFS question

NTDEV
1

I’m new to this list, so excuse me if my question is addressed improperly.
I need help with AddUsersToEncryptedFile() function usage or rather
how to use EFS_CERTIFICATE_BLOB type.
How to get EFS_CERTIFICATE_BLOB for particular user?
Unfortunately, I was unable to find any examples regarding this specific API
call.
Any code sample would be great.

Any help would be appreciated!

Sincerely,

I wonder how many people might have tried this specific thing.

My experience with many of these CryptoAPI functions was not very good.
Sometimes they just don’t work anyway.

Apart from the documentation in the Platform SDK there is just luck, understanding & hit-n-trial that can work.

I also recall someone from Microsoft telling me about 6 months back that CryptoAPI 2.0 doesn’t support adding multiple users to an encrypted file. Although I could find documentation & APIs mentioned in this regard.

Hey the API is no big deal man.

U should be able to find it in either NTFS in FS Section or CyptoAPI Section in Platform SDK.

That is where I recall, I found it, its been 7-8 months.
