    Another thing...

    Another thing. I also understand that this is encrypted using several keys. Thusly, encrypted several times.

    So how would a brute-force attack work in this case? Because I believe there are a total of 3 hashes involved in EFS encryption.


    Thanks for the help.

    look at this thread that I'v made a while ago

    It deals w/ the same issue.

    Also if you search for my threads around the same time you will find more questions from me about EFS

    JUST TO LET YOU KNOW... I ENDED UP LOOSING THE DATA. EFS IS "SO FAR" QUITE SECURE

    This link takes you directly to the high level overview of how the files are encrypted-

    In reading through that document I did notice that it does not talk about AES encryption. The process should be very similiar in that you just replace 3DES or DESX with AES in XP SP1 and higher.
