How To Restore The Certificate Encryption File System?

You may receive an error message indicating the file system to encrypt the certificate. Well, there are different ways to solve this problem and that is what we are going to do now. EFS is User Based Shift Control. Essentially, it works like this: when a user requests to encrypt a file or folder, an EFS certificate is created for the user and their exclusive key is stored in the owner’s profile.

  • Windows 10 version 1607 and later
  • If you don’t already have an EFS DRA certificate, you must create one and extract it from your method before you can use Windows Information Protection (WIP), formerly known as Data Protection of the market (EDP), in your relationship. . For the purposes of this article, we will use the file name EFSDRA; However, this name can be changed to whatever you want to make sure you do.

    Create The EFS DRA Certificate Manually

    1. On a computer without an EFS DRA certificate installed, open an elevated command and navigate to where you want to save my certificate.

    2. Run command:

      encrypt this /r:EFSRA

      Where EFSRA is the name of the .cer and .pfx files to be generated.

    3. When prompted, enter and confirm a password to secure your new PFX (Personal Information Exchange) file.

      The pfx files EFSDRA.cer and EFSDRA.Files will be launched in the folder specified in step 1.


      Because the private car keys in your D filesRA PFX can certainly be used to decrypt a WIP transmission, you must protect them properly. We strongly recommend that you keep these files offline and keep copies in a secure smart account for normal use and master copies in a private physical location.

    4. Add DRA EFS entries to your WIP policy using a deployment tool such as Microsoft or Intune Microsoft Endpoint Configuration Manager.

      Which three types of certificates are used with EFS?

      Certificate Services offers three types of certificate templates that support EFS: EFS Basic, User, and Administrator.


      These credentials can be used in Intune to get enrollment device (MDM) and deenrollment (MAM) device cable policies.

    Make Sure All Your Data Recovery Certificates Are Properly Created On The WIP Machine

    1. Search for a member or create a password-protected file using Windows Information Protection. For example, you can open an app from the list of allowed apps, and then create and save a file that says it’s WIP encrypted.

    2. Open a software package from the list of protected applications, and then create and save a file for WIP encryption.

    3. OpenOpen an elevated command prompt, navigate to where you saved the file you just created, and run the following command:

      certificate encrypting file system

      cipher /c filename filename

      No doubt where is the name of the directory you created in step 1.

    4. Make sure your data recovery certificate is clearly listed in the list of recovery certificates.

    Restore Data In A Test Environment Using An EFS DRA Certificate

    1. Copy your own encrypted WIP file to a folder where you have administrator rights.

    2. What does the Encrypting File System encrypt?

      Encrypted File System or EFS also provides another layer of security for files and directories. It provides cryptographic protection for individual files on physical NTFS file volumes using a public key system.

      Install the EFSDRA.pfx file with its password.

    3. Open the main command with elevated privileges, navigate to the encrypted file and run the following command:

      cipher /d encrypted file.extension

      Where is the encrypted file. The name of your encrypted directory. Example: corporateddata.docx.

    Restore Secure WIP After Logout

    certificate encrypting file system

    It is possible to undo a file from an unregistered device, only to restore it later each time. This can happen when I’m awayThe host device is currently being returned or when an unregistered handler is re-registered. If the employee logs back in with the original user profile, or if a revoked keystore is stored on the device, all revoked data can be restored by opening .


    1. Ask the employee to log in as a disconnected device, open a bloated command prompt and type:

      Robocopy "%localappdata%MicrosoftEDPRecovery" "new_location" 6 . /EFSRAW

      Where “new_location” is in another trusted directory. This could be on the employee’s device, or in an actual shared folder on a computer that experts say is running Windows 8 or Windows Server 2012 or later and that you can usually access by logging in as a data recovery agent .

      To start Robocopy mode, open the Task Manager. Click File > Run New Plan, enter the command, and click Create Task with Administrator Rights.

      If an employee performed a clean install and user profileThe owner is also missing, the owners must restore the keys currently located in the system volume folder on the disk. Type:

      How do I get my EFS certificate?

      In the left pane, go to Trusted People → Certificates. You will see a list of PC users who have EFS certificates. Double-click each entry to display the user’s EFS certificate properties dialog box.

      Robocopy "drive letter:System Volume InformationEDPRecovery" "new_location" */EFSRAW
    2. Log in to the unusual device with administrator credentials that allow access to your organization’s certificate, skip decrypting the file as a recovery by typing:

      cipher.exe /D "new_location"
    3. Have an employee sign in to each unregistered device and enter:

      Robocopy "new_location" "%localappdata%MicrosoftEDPRecoveryInput"
    4. Ask the participant to lock and unlock the device.

      The Windows ID service automatically updates previously revoked employee keys due to the RecoveryInput location.

    Automatic Recovery Of File Encryption Keys

    Starting with Windows 10 version 1709, WIP includes a data recovery feature that allows your employees to automatically restore access to their work files if the encryption factor is lost and the files they need are no longer available. This is pr Occurs, for example, when an employee re-images the system partition to do work, deletes information from a WIP solution, or when a device is typically marked as lost and you unnecessarily select the wrong device to log out.< /p>

    In order for employees to always have access to their files, WIP generates a useful auto-recovery key that is backed up with its Azure Active Directory (Azure AD) identity.

    Employee experience is based on Azure AD work account sign-in. An employee can:

  • Add a specific work account by going to Windows Settings > Accounts > Work or School Access > Login Menu.
