Windows server uses .pfx / .p12 file to store the public key file (public key) (SSL certificate) and a private key file (private key). Certificate authorities (CA – Certificate Authority) provide SSL certificates (public key files). You use the server to create a private key file at the location where the CSR is generated.
You need both public and private keys for the SSL certificate to work properly on any system. Windows uses the pkcs # 12 file (pfx / p12) to store these two keys and another intermediary certificate in the chain of trust chain. So if you want to transfer an SSL certificate from a Windows system to another system using a PFX file or store the certificate in another secure location, you need to create a pkcs # 12 backup (pfx / p12).
To export / import SSL certificates using PFX using MMC Windows with private keys and intermediate certificates, follow the steps below:
Step 1: Create an MMC Snap-in
Create an MMC Snap-in so that the Certificate Manager is on the first Windows system where the SSL certificate is installed.
first. Access Start =>Run (or press Windows + R) to open a Run command window, then type MMC on that and press Enter.
2. On the window displayed on the screen, access Console tab =>File =>Add / Remove Snap-in.
3. Click here Add =>Certificates then click Add next.
4. Choose Computer Account =>Next.
5. Choose Local Computer =>Finish.
6. Close the Add Standalone Snap-in window.
7. Click here OK, got it on the Add Standalone Snap-in window.
Step 2: Export / backup the certificate to the .pfx file.
first. On the MMC Double window, click Certificates (Local Computer).
2. Double click on the folder Personal, then find Certificates.
3. Right-click on the certificate you want to back up, select ALL TASKS =>Export.
4. Follow the steps on the Certificate Export Wizard to back up your certificate to the file .pfx.
5. Choose Yes, export the private key.
6. Choose Include all certificates in certificate path if possible, but note that the option is not selected Delete Private key.
7. Enter the password you want to use.
8. Choose a location to save the file.
9. Click here Finish.
ten. A message will appear on the screen saying that the export was successful: “The export was successful”.
Click here OK, got it, so you have successfully exported / imported an SSL certificate using PFX using MMC Windows. The backup .pfx file will be at the location you selected and you can move the file to other locations more safely.
