How would one read an encrypted file's (encrypted using windows' EFS) header? I would like to be able to read the header and extract FEK that was encrypted by either the public or private key of the file.
From reading up I understand the structure of the file header I'm just not sure how to go about reading the header. Also it would be a great help if you could point me in the direction of any apps that read a file header and display it on screen.
EDIT: By encrypted file I mean that it was encrypted using EFS on my previous system and backed up and put onto my current system so they aren't treated as encrypted files anymore but they are encrypted.
