Decrypting EFS

By admiral007 ·
I think that my situation with EFS is a little unique. I was in the military, and when I left this month, I needed to de-militarize my computer?in doing so, I became the administrator of my computer (as opposed to having the administrator be someone/some computer in charge of all the computers in the military network). I had encrypted files on my computer before de-militarizing it and did not think accessing them would be a problem since I was going to be the administrator. However, when I changed to the administrator, I lost access to all these files. I tried to simply decrypt them, and it said that access was denied and there was an ?error code 5? (I couldn?t find out what this error code is) I scanned my computer, and I have no Recovery Agent present in my system. The key is there (I think), but it is encrypted as well. I have tried numerous programs to recover or decrypt these files, and haven?t had any luck so far. Is there any hope of me getting these files back? i am willing to try just about anything at this point. Is there anyone who has any more suggestions on what I should do? If I can?t figure out something soon, I am probably just going to have to clear my hard drive (and that is something I really don?t want to do?). Thanks.

If the encryption key was lost and not backed up, you would need to crack the encryption. This is no easy task, for the most part, your encrypted files are lost.... Unless you have a backup of the encryption key (not residing in an encrypted area).

eeror code 5 means Server's key is encrypted in an old master key.
use Cipher.exe to decrypt a folder or file

To decrypt the folder, \Encrypted Files, type

C>cipher /d /s:"C:\Encrypted Files"

Press Enter.
