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:

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:
- 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.

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.

Overview
The following is an extremely simplified view of how SSL is implemented and what part the certificate plays in the entire process.
In the newer Mac OS, the user accounts don't have ssh-agent launched within each session and the user key is not remembered. As far as I can tell, when a user wants to interact with GitHub or some other Git remote using ssh protocols, it is necessary to run these two lines the terminal: $ eval '$(ssh-agent -s)' $ ssh-add -K /.ssh/idrsa. Git ssh key mac. Add Your SSH Key to Pantheon Log in to Pantheon and go to the Account tab in your User Dashboard. Click SSH Keys. Paste the copied public key into the box, and click Add Key.
Normal web traffic is sent unencrypted over the Internet. That is, anyone with access to the right tools can snoop all of that traffic. Obviously, this can lead to problems, especially where security and privacy is necessary, such as in credit card data and bank transactions. The Secure Socket Layer is used to encrypt the data stream between the web server and the web client (the browser).
SSL makes use of what is known as asymmetric cryptography, commonly referred to as public key cryptography (PKI). With public key cryptography, two keys are created, one public, one private. Anything encrypted with either key can only be decrypted with its corresponding key. Thus if a message or data stream were encrypted with the server's private key, it can be decrypted only using its corresponding public key, ensuring that the data only could have come from the server.
If SSL utilizes public key cryptography to encrypt the data stream traveling over the Internet, why is a certificate necessary? The technical answer to that question is that a certificate is not really necessary - the data is secure and cannot easily be decrypted by a third party. However, certificates do serve a crucial role in the communication process. The certificate, signed by a trusted Certificate Authority (CA), ensures that the certificate holder is really who he claims to be. Without a trusted signed certificate, your data may be encrypted, however, the party you are communicating with may not be whom you think. Without certificates, impersonation attacks would be much more common.
Step 1: Generate a Private Key
The openssl toolkit is used to generate an RSA Private Key and CSR (Certificate Signing Request). It can also be used to generate self-signed certificates which can be used for testing purposes or internal usage.
The first step is to create your RSA Private Key. This key is a 1024 bit RSA key which is encrypted using Triple-DES and stored in a PEM format so that it is readable as ASCII text.
Step 2: Generate a CSR (Certificate Signing Request)
Once the private key is generated a Certificate Signing Request can be generated. The CSR is then used in one of two ways. Ideally, the CSR will be sent to a Certificate Authority, such as Thawte or Verisign who will verify the identity of the requestor and issue a signed certificate. The second option is to self-sign the CSR, which will be demonstrated in the next section.
During the generation of the CSR, you will be prompted for several pieces of information. These are the X.509 attributes of the certificate. One of the prompts will be for 'Common Name (e.g., YOUR name)'. It is important that this field be filled in with the fully qualified domain name of the server to be protected by SSL. If the website to be protected will be https://public.example.com, then enter public.example.com at this prompt. The command to generate the CSR is as follows:
Step 3: Remove Passphrase from Key
One unfortunate side-effect of the pass-phrased private key is that Apache will ask for the pass-phrase each time the web server is started. Obviously this is not necessarily convenient as someone will not always be around to type in the pass-phrase, such as after a reboot or crash. mod_ssl includes the ability to use an external program in place of the built-in pass-phrase dialog, however, this is not necessarily the most secure option either. It is possible to remove the Triple-DES encryption from the key, thereby no longer needing to type in a pass-phrase. If the private key is no longer encrypted, it is critical that this file only be readable by the root user! If your system is ever compromised and a third party obtains your unencrypted private key, the corresponding certificate will need to be revoked. With that being said, use the following command to remove the pass-phrase from the key:
The newly created server.key file has no more passphrase in it.
Step 4: Generating a Self-Signed Certificate
Openssl Generate Private Key
At this point you will need to generate a self-signed certificate because you either don't plan on having your certificate signed by a CA, or you wish to test your new SSL implementation while the CA is signing your certificate. This temporary certificate will generate an error in the client browser to the effect that the signing certificate authority is unknown and not trusted.
To generate a temporary certificate which is good for 365 days, issue the following command:
Step 5: Installing the Private Key and Certificate
When Apache with mod_ssl is installed, it creates several directories in the Apache config directory. The location of this directory will differ depending on how Apache was compiled.
