Backing Up and Restoring the Certificate Services Private Key - Win32 apps (2024)

FAQs

How do I backup my certificate private key? ›

To back up a Certificate Services private key, use the Certification Authority MMC snap-in, or the certutil command (with -backup or -backupkey specified). Backing up the private key with the Certification Authority MMC snap-in or certutil results in the private key being written to PKCS #12 file.

In the Certification Authority snap-in, right-click the CA name, click All Tasks, and then click Back up CA to start the Certification Authority Backup Wizard. Click Next, and then click Private key and CA certificate. Click Certificate database and certificate database log. Use an empty folder as the backup location.

A missing private key could mean: The certificate is not being installed on the same server that generated the CSR. The pending request was deleted from IIS. The certificate was installed through the Certificate Import Wizard rather than through IIS.

Recovery from Failures

Press the Win+R keys to open Run dialog, type certmgr. msc, and click OK. Step 2: In the left pane of certmgr, expand the Personal store, and open Certificates. Then select all certificates for Encrypting File System, right-click these selected certificates, click on All Tasks and click on Export.

The certificate store is located in the registry under HKEY_LOCAL_MACHINE root. Current user certificate store: This certificate store is local to a user account on the computer. This certificate store is located in the registry under the HKEY_CURRENT_USER root.

Windows stores certificates locally on the computer in a storage location called the certificate store. A certificate store often has numerous certificates, possibly issued from a number of different certification authorities (CAs). For info on viewing certificates, see How to: View certificates with the MMC snap-in.

If you lose your private key, you will be unable to install your SSL certificate and will need to generate a new key pair (CSR + Private Key) and re-issue the certificate.

Conversely, data that has been encrypted with a private key can be decrypted only with the corresponding public key. The owner of the key pair makes the public key available to anyone, but keeps the private key secret. A certificate verifies that an entity is the owner of a particular public key.

The path to your private key is listed in your site's virtual host file. Navigate to the server block for your site (by default, it's located in the /var/www directory). Open the configuration file for your site and search for ssl_certificate_key which will show the path to your private key.
