I need assistance to decrypt backed up data files (mostly image files such as jpg) that have been encrypted using windows XP utility, EFS Encryption, by following these steps:
1.) right-click on a file
2.) select properties
3.) click on "advanced" in the attributes section.
4.) select "Encrypt contents to secure data"
All files have been copied to an external disk, then the computer was reformatted and restored to factory condition. I found out that I no longer have access to these files (they appear green in windows explorer).
I am not able to decrypt my files.
How can I decrypt these files without the original key?
Thanks
