Cause:
Entrust SSL certificates do not include a private key. The private key resides on the server that generated the Certificate Signing Request (CSR). When installed correctly, the Server Certificate will match up with the private key as displayed below:
If the private key is missing, the circled message indicating a good correspondence with private key will be missing as shown here:
The Certificate Authority (CA) provides you with your SSL Certificate (public key file). You use your server to generate the associated private key file where the CSR was created. You need both the public key and private keys for an SSL certificate to work properly on any system. It should be saved safely on the server you generated it on. Do not send your private key to anyone, as that can compromise the security of your certificate. 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. The private key for an SSL Certificate is something that is generated when you create a CSR. During the CSR creation process, the server will usually save the private key in one of its directories. During the CSR creation process, the server will usually save the private key in one of its directories. Apr 10, 2020 Client and server exchange key information for establishing communication. Generating an SSL Certification. To configure an SSL connection between servers we need to configure an SSL certificate on the service. It is done using OpenSSL. 1) Create One Directory where we are going to save our certificate and Private key. Mkdir sslcerts.
A missing private key could mean:
- Jun 09, 2019 This article describes how to recover a private key after you use the Certificates Microsoft Management Console (MMC) snap-in to delete the original certificate in Internet Information Services (IIS). You delete the original certificate from the personal folder in the local computer's certificate store.
- Jul 08, 2009 You can also generate self signed SSL certificate for testing purpose. In this article, let us review how to generate private key file (server.key), certificate signing request file (server.csr) and webserver certificate file (server.crt) that can be used on Apache server with modssl. Key, CSR and CRT File Naming Convention.
- Dec 01, 2015 To generate a self-signed certificate file on a Windows system: You will need to have OpenSSL installed. Open a command prompt window and go to the directory you created earlier for the public/private key file.
- 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.
In this technote we do not discuss how to determine the reason the private key is missing. Select the link corresponding to each reason listed above for more information.

1) Snap-In Configuration
2) Import the Server Certificate
3) Recover the private key
Use the following steps to add the Certificates snap-in:
1. Click Start, and then search for Run.2. Type in mmc and click OK.
3. From the File menu, choose Add/Remove Snap-in.
4. Select Certificates and then Add.
5. Choose the Computer account option and click Next.
6. Select Local Computer and then click Finish.
7. Click Close, and then click OK. The snap-in for Certificates (Local Computer) appears in the console.
Use the following steps to import your Server Certificate into the Personal certificate store. If the Server Certificate has already been imported into the Personal store, you may skip this step.
From the MMC console opened in the above steps:
1. Expand the Certificates (Local Computer) tree in the left preview panel.
2. Right-click Personal and select All Tasks > Import.
3. The Certificate Import Wizard appears. Click Next.
4. Browse to the location of your Server Certificate file and click Next.
5. Select Place all certificates in the following store and click Next.
6. Click Finish to complete the Certificate Import Wizard.
7. A dialog box appears indicating the import was successful. Click OK.Use the following steps to recover your private key using the certutil command.
1. Locate your Server Certificate file by opening Microsoft Internet Information Services Manager, then on the right side select Tools > Internet Information Services (IIS) Manager.
2. Once in IIS Manager, select your server, then on the right side, Server Certificates. You will see all certificates currently on that server. Scroll over the certificate you are trying to install, right click, then select View.
3. There, you can view the certificate information. As you can see, there is no indication of a good correspondence with the private key.
4. Click the Details tab. Write down the serial number of the certificate.
5. We will need to recover the private key using a command prompt. In order to recover the key, we must do so using command prompt as an administrator. To do so, slick Start, then on then open all App. Under Windows System, find Command Prompt. Right click Command prompt and then Run as administrator. Confirm the action and continue.
6. Make sure you are on the right directory in command prompt.
e.g., if your server directory is “c:/users/srv2012_r2_std_x64”, on the command line type “cd c:/users/srv2012_r2_std_x64”. Note that “cd” is the command used to change directories in command prompt.
7. Now that we are in the right place, enter the following command at the prompt: certutil –repairstore my <serial number> where <serial number> is the serial number obtained in Step 2 with spaces removed.
8. If Windows is able to recover the private key, you see the message:
CertUtil: -repairstore command completed successfully.
If your private key was recovered successfully, your Server Certificate installation is complete.
If the private key was not recovered successfully, you will need to generate a new Certificate Signing Request and submit it to Entrust Datacard to have your certificate re-issued, or re-issue the certificate using your ECS Enterprise account.
Check that your Certificate has been successfully installed by testing it on the Entrust SSL Install Checker.
