Using the cPanel SSL/TLS Manager

Once you have the cPanel SLL/TLS Manager enabled in WHM, you can access it when logged into cPanel.

  1. Login to cPanel

  2. under security click ssl tls manager

    Under the Security section, click on SSL/TLS Manager


Generate Private Keys

Before generating anything else, we need to generate some Private Keys, these are used to decrypt information transmitted over an SSL connection. You need a separate Private Key for each SSL certificate you wish to use.

  1. click generate private keys

    Access the cPanel SSL/TLS Manager

    Click on Generate, view, upload, or delete your private keys


  2. click generate

    Typically a Key Size of 2,048 bits is fine, but if you need another one you can select it from the drop-down.

    Fill in a Description for the key if you'd like, then click Generate


  3. cpanel generated private key

    Now with your Private Key generated, click on Return to Private Keys

    You should see the key you created listed

    cpanel view keys on server


  4. paste or upload private key

    If you already have a Private Key not on the server, then under the Upload a New Private Key section, you can either paste in your key and click on Save, or you can click on Choose File to browse your computer for the key, and then click Upload

    After you've already generated or uploaded your Private Key so it exists on the server, click on Return to SSL Manager


Generate CSR

Before getting an SSL certificate for your website, you need to generate a Certificate Signing Request (CSR). This request will include your domain name and company, as well as information specific to the server you're hosting on.

  1. click generate csr

    Access the cPanel SSL/TLS Manager

    Click on Generate, view, or delete SSL certificate signing requests


  2. fill out csr fields click generate

    Fill out all of the fields for your CSR, then click Generate


  3. copy generated csr text

    You should now see the generated CSR, you can click in the text-box and then hit Ctrl-A to select all the text, and then Ctrl-C to copy it.


  4. Now you need to take this CSR text generated from the cPanel server, and when you are purchasing a SSL certificate, the Certificate Authority that you buy it from will need to be supplied with it.

    When asked the server type your CSR was generated on, you'd want to select RedHat Linux.

Generate a self-signed SSL certificate

If you just need your website data encrypted, and are not worried about web-browser warnings you can generate a self-signed SSL certificate for free.

When you access a self-signed SSL website from your web-browser, you will get an self signed SSL warning such as this one in Google Chrome. You can simply safely click on Proceed anyway to still get to the website.

self signed ssl warning click proceed anyway

When you're on your website if you click on the SSL padlock icon, you can see the reason we got a warning is because the website's identity has not been verified. This is because we used a self-signed SSL certificate and it wasn't verified by a 3rd party certificate authority

self signed ssl info
  1. click generate certificate

    Access the cPanel SSL/TLS Manager

    Click on Generate, view, upload, or delete SSL certificates


  2. fill out details for self signed ssl certificate click generate

    Scroll down to the Generate a New Certificate section and fill out all of the details for your self-signed SSL certificate, click Generate


  3. copy self signed certificate text

    On the next page, click in the Encoded Certificate text-box, then hit Ctrl-A to select all the text, and then Ctrl-C to copy it.


Install 3rd party SSL certificate

If you sent off your CSR to a certificate authority, you should have gotten back a matching SSL certifcate that you can now go back and install on the server to use for your website.

  1. click generate certificate

    Access the cPanel SSL/TLS Manager

    Click on Generate, view, upload, or delete SSL certificates


  2. paste or upload your ssl certificate

    Now either paste your certificate info into the Paste your certificate below box and click Save Certificate

    Or click Choose File to browse your local computer for the certificate file and click on Upload Certificate


Activate SSL certificate on web site

Now that you've generated a private key, generated a CSR, and installed a SSL on your account, you should be ready to activate that SSL certificate for your website.

  1. click setup an ssl certificate to work with your site

    Access the cPanel SSL/TLS Manager

    Click on Install and Manage SSL for your site(HTTPS)


  2. select ssl domain click autofill by domain

    From the Domain drop-down, select the domain you're installing your SSL certificate on, and then click Autofill by Domain


  3. click install certificate

    In this case you can see it's warning us that the Issuer is self-signed which is fine. If you actually installed a 3rd party verified certificate you shouldn't see this warning.

    Click on Install Certificate



You will then see confirmation that the SSL certificate was installed. You should hopefully now understand how to use the cPanel SSL/TLS Manager to either generate a CSR or get a SSL certificate installed on your website.
