Decrypt Files on Windows with Your Personal Encryption Key

Article Reference ID: 000247010

If you chose to use your own personal encryption key when you first installed Mozy software on your computer and you later used Mozy on the Web to recover your files, you can download the Crypto Utility to provide your personal key and thereby decrypt those files. This applies to files you download from backed up computers as well as to your files synchronized in the Mozy cloud.

You can decrypt files on a Windows computer or on a Mac, regardless of what computer they were originally backed up from. If you are restoring to a Mac, read this topic: Decrypt Files on a Mac with Your Personal Encryption Key. If you are restoring from one platform to another, there are specific issues you should be aware of. For more information, see Why Platform Matters.

  1. Click the appropriate link to download the Crypto Utility.
  2. Save the file to a location you will remember later (such as your Desktop).
  3. Right-click on the Crypto Utility file, then click Run as administrator to run the program.
