Windows servers use .pfx/.p12 files to contain the public key file (SSL Certificate) and its unique private key file. You need both the public key and private keys for an SSL certificate to work properly on any system. If you need to transfer your SSL certificate from one server to another or store it someplace for safe keeping you need to create a .pfx backup. 

Dell Sonicwall systems have the capability to import a pfx file generated from windows.

To backup, export, and move an SSL certificate from a Windows Server to SonicWALL with its private key perform the following steps.

Step 1:  Create an MMC Snap-in for Managing Certificates on the IIS 8 system:

  1. Start > run > MMC.
    mmc
  2. Go into the Console Tab > File > Add/Remove Snap-in.
    mmc
  3. Click on Add > Click on Certificates and click on Add.
    mmc
  4. Choose Computer Account > Next.
    mmc export
  5. Choose Local Computer > Finish.
    mmc export
  6. Close the Add Standalone Snap-in window.
  7. Click on OK at the Add/Remove Snap-in window.

Step 2: Export/Backup certificate to .pfx file:

  1. In MMC Double click on Certificates (Local Computer) in the center window.
  2. Double click on the Personal folder, and then on Certificates.
  3. Right Click on the Certificate you would like to backup and choose > ALL TASKS > Export
  4. Follow the Certificate Export Wizard to backup your certificate to a .pfx file.
    mmc export
  5. Choose to ‘Yes, export the private key
    mmc export
  6. Choose to “Include all certificates in certificate path if possible.” (do NOT select the delete Private Key option)
    mmc export
  7. Enter a password you will remember.
  8. Choose to save file on a set location.
  9. Click Finish.
    mmc export
  10. You will receive a message > “The export was successful.” > Click OK.The .pfx file backup is now saved in the location you selected and is ready to be moved or stored for your safe keeping.

Step 3: Importing your PFX file into SonicWALL NSA:

  1. Log into your SonicWALL NSA system.
    SonicWAll_Login_
  2. Once you are in the portal navigate to System and click Certificates.
  3. You will see a list of all the certificate you have on the system currently.
  4. Click Certificate and Certificate Requests.
  5. Click Import.
    SonicWALL Certificate intermediate import
  6. In the Import Certificate window perform the following..
    1. Select Import a local end-user certificate with private key from a PKCS#12 (.p12 or .pfx) encoded file.
    2. In the Certificate Name, specify a name for the certificate you are importing.
    3. In the Certificate Management Password, specify the password you applied to your pfx file that you are importing.
    4. Click Browse to specify the location and path of your pfx file to import.
    5. Click Import.

After the certificate is imported it will appear in the list of certificates on the Certificates page.

Step 5: Binding the new SSL Certificate to your Website:
