Before you encrypt anything important, you should back up your
personal encryption certificate (with its associated private key)
and the recovery agent certificate to a floppy disk and store it in
a secure location. If you ever lose your original certificate
(because of a hard disk failure, for example), you can restore
the backup copy and regain access to your files. If you lose all
copies of your certificate (and no recovery agent certificates exist),
you won't be able to use your encrypted files. No back door exists,
nor is there any practical way to hack these files.
(If there were, it wouldn't be very good encryption.)

Without a backup of the original Encryption Certificate Key, encrypted files
are unrecoverable as they will stay encrypted forever. There is no recovery
method since the encryption algorithm is now completely different with a
reinstall of Windows XP.

I have a XP system that crashed the user reinstalled XP. The users folders were encrypted. I took owner ship of the files and can set the files but they are still encrypted. They show up green and when selected the message is access denied the details say the t the file is in use. Is there any way to break the encryption and open the files
