Guest AHMED FAREED Posted October 6, 2007 Posted October 6, 2007 hi friends ive problem in an encrypted file,i encrypted some files and i saved them on the partition D of my hard disk , then i formated the system which was on the C partition and i installed fresh copy of xp professional as the previous one, when i tried to access the files ,i encrypted b4, i found those files unaccessable, i saw the options of the file-->advanced--->encryption deatails--->i saw it is allowed only to the account i had in the previous system that i formatted :( and i saw that there is smth called certificate for that account and special thumbprit and those r so advanced for me !! i wonder is there any way to decrypt those files?

Without having your certificates, your chances of restoring your files are unfortunately close to nil. In future make sure to become familiar with the encryption process AND to back up your certificates.

If by encryption you mean that you used EFS (encryption file system), you need to designate an alternate recovery agent or export your EFS certificate after creating it (i.e., after the first time you use EFS to encrypt a file). The security key associated with the EFS cert is unique to a particular instance of the OS. You blew away that instance of the OS and installed a new instance. The old EFS cert isn't defined in your new instance of the OS. You need to import your previously exported EFS cert to decrypt the files that were encrypted under that old EFS cert. Since you don't have the EFS cert to import, you won't be getting into those encrypted files. There is no backdoor to EFS. In "Start -> Help and Support", for EFS, it describes how to export and import the cert.

Sure, if you have any friends in the NSA and a couple of years for them to work on those files. By the way, what State secrets were you protecting? There is very little need to use high level encryption on a personal home computer. Frankly, it's a disaster waiting to happen, and there are easier ways to protect your data that aren't going to give you TRASH that you will never see again when you screw up, as you did, with your encryption scheme.
