EFS Encryption

Hello everyone,

I'm in a bit of a bind here. I had a computer that needed to be reformatted.
I had some documents on it that I put into a folder and I put the EFS
Encryption on. Now I know the EFS Encryption leaves behind a file that you
need in order to open that data again. Well, At the time I wasn't thinking
about the encryption key so I went ahead and backed the files up on a USB
disk.

Here comes my dilemma. I need these files back. I have tried just about
every program I can think of but couldn't find anything to decrypt EFS.
Maybe you all know of some that work? Maybe you know of another way to get
them to become un-encrypted? Some of the things I have tried was encrypting
a folder and copying those files over to that folder. Didn't work. Wasn't
even able to move the files off the Hard drive. I tried changing permissions
about a million ways using the command cacls. I even tried a recovery
program to see if there was anyway I could find the OLD encryption key to
unlock those files.

Anyone know of anything that may help? If you do, I will forever be in your
debt.

Thanks,
McKeder

  1. You may have to pay a data forensics or eDsicovery company to hack the encryption.

    Good luck with that, I guess. Their biggest chance is to search for non-overwritten sectors, and hope the old key can be recovered.

    I already tried that. They refused to even touch it. They said "There is no proof they are your files and we can't be held accountable for opening them."

    Thats why I posted here :)
  4. Well, if you are willing to pay for that, there is a lot of commercial software that will decrypt the files for you:
