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
- Open the Certificates (Local Computer) snap-in you added > select Personal > Certificates
- Right-click certificate name > select All Tasks > Export.
- The Certificate Export Wizard opens > click Next
- Select Yes, export the private key > click Next
- Select Personal Information Exchange
- Ensure to check only Include all certificates in the certificate path if possible > click Next
- Enter and confirm a password > click Next
- Choose a file name and location for the export file > click Next
- 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.
