Recover encrypted files

If a file is encrypted with a key that is not available in your keyring, you cannot open the file. This might be the case because you are not supposed to access this file according to company policy. However, in some cases, you may be allowed access to the file but you just happen not to have the required key. In this case, you need to find out which key was used and ask your security officer to assign the key to your keyring. Proceed as follows:

  1. Right-click the file and select Show Encryption State from the context menu.
    The key used for encrypting this file is displayed.
  2. Contact your security officer and provide them with the key name.
  3. Ask your security officer to assign the key to your keyring.
  4. As soon as your security officer confirms that your user policy has been updated, go to System Preferences > Sophos SafeGuard > Server.
  5. Click the Synchronize button.
  6. Open the Keys tab and check whether the required key is displayed in the list.
If the key that was used for encrypting the file in question is listed in the Keys tab, you can now access the file.
