Lost Encryption Keys

Posted: 07-06-2008, 01:33 AM
My PC crashed, forcing a reload. I had stored some files in an
encrypted folder on a separate partition.

Like a bonehead, I didn't save the keys before the crash.

Is there anyway I can get to the file contents?


Help!!!!!!

If you made a backup to a different drive or to a DVD prior to the
crash you can backup your current configuration, use your backup to decrypt
the folder, get the information you need and then restore. Otherwise, you're
out of luck.
Any and all information of an important nature should always be backed
up on a regular basis.

If you've used EFS and did not properly back up your private key, you're
toasted. If the computer was a member of a domain you could have removed EFS
by using the Recovery Agent's user account and private key. But on a Vista
stand-alone machine there is NO Recovery Agent, and even of there was, since
you formatted the drive all the data on it is lost.

You could try to use Elcomsoft's EFS recovery tool, but it costs money and
I'm not sure it will help when the machine was formatted.

In many cases, it does. Professional version of our software scan the disks
by sectors, searching for keys by patterns, and if they have not been
overwritten
by other data -- they're retrieved and so could be used for decryption.

But I'd recommend to try the the free trial version, of course -- at least
it
detects whether any keys are still there, and whether the files are
decryptable:
