Export or Back Up a SSL Certificate in Microsoft IIS 5.0, 6.0, 7.0 or 8.0


In some situations, you may want to export or back up a server certificate. For example, to store a back up copy of your private and public keys, or if you are moving (migrating) a website to another server.

To export or back up an SSL certificate from Microsoft IIS 5.0, 6.0, 7.x or 8.0, you save a copy of the certificate (including its associated private key) to a .PFX file:
Step 1: Create a Microsoft Management Console (MMC) Snap-in for managing certificates 
  • Create a Microsoft Management Console (MMC) Snap-in for managing certificates, as described in solution SO1849.
Step 2: Export/ Back Up the certificate
  1. Open the Certificates (Local Computer) snap-in you added > select Personal > Certificates
  2. Right-click certificate name > select All Tasks > Export.
  3. The Certificate Export Wizard opens > click Next
  4. Select Yes, export the private key > click Next
  5. Select Personal Information Exchange
  6. Ensure to check only Include all certificates in the certificate path if possible > click Next
  7. Enter and confirm a password > click Next
  8. Choose a file name and location for the export file > click Next
  9. Click Finish

Note: Thawte strongly recommends that you save the file to a removable media. If you saved the file to a local disk, then the .PFX file is copied when the disk is backed up. This may compromise security.
