Before you can install your SSL certificate after purchase you need to generate a Certificate Signing Request (CSR) and send it to your SSL vendor. If you purchased your SSL from KnownHost the CSR can be entered at https://my.knownhost.com. If you purchased your SSL certificate somewhere else you'll enter it on the website where you purchased the certificate.

Click here for help generating your Certificate Signing Request (CSR).

All SSLs purchased through KnownHost come with a token. This token can be used for easy installation on our shared and reseller hosting packages.

You can get your token in one of two ways:

When you login to https://my.knownhost.com click on the manage button for the SSL you want to get the token for. Click on Certificate Details on the left and you'll be presented with the token.

The token is emailed to you when you purchase the SSL certificate. Within the email you'll find a snippet similar to the following:

Token : DD0487376AMTI4MDUx0#!mg7eukwb7yy7dy7zn777

Tokens can be used within the cPanel interface by clicking on the AutoInstall SSL icon.

Enter your token here and click Verify Token.

Once you enter your token here you'll be guided through every step of the SSL setup process.

This guide assumes that you have already generated the Certificate Signing Request (CSR), and the private key is already stored on the server. If the private key has not been added, you can do so in a below step. In cPanel, click on the icon labeled SSL/TLS.

From this screen, click on the link Generate, view, upload, or delete SSL certificates under the "Certificates (CRT)" heading.

You can copy and paste the entire certificate (including the —–BEGIN CERTIFICATE—– and —–END CERTIFICATE—– lines: they are important) into the provided text box. If the certificate was pasted correctly, cPanel will show more information regarding the certificate like so:

Domains: yourSSLdomain.tld
Issuer: CoolSSLIssuer
Key Size: 2,048 bits (c031337 …)
Expiration: Feb 13, 2018 9:30:42 AM

You can enter a description with the provided box as well – entering a date and description can help you keep your certificates organized. Once the certificate has been entered (with an optional description) you can click on Save Certificate. If it was successful, you will get a message from cPanel saying the certificate has been saved.

If your certificate was provided in the .crt file format (you may need to extract this file from a zip archive) you can choose the Browse… button to select the file from your computer (or other device) and upload it to the server without having to copy and paste the information directly. Once you have selected the file (and entered an optional description) click on the Upload Certificate – if the certificate is in the right format, cPanel will automatically save the certificate for you.

From the SSL/TLS screen in cPanel, click the link Manage SSL sites under the "Install and Manage SSL for your site (HTTPS)" heading.

Scroll down to the Install an SSL Website heading, and click the drop-down box under the section called Domain (with the text "Select a Domain") and choose the domain that you wish to install an SSL certificate for.

If you installed the certificate according to the steps above (and the private key is already on the server after generating a CSR) you can click on the Browse Certificates button and select the certificate you just entered and click on Use Certificate – this will fill in the appropriate information for you. If you only have one domain or a single certificate uploaded, you can click on Autofill by Domain and cPanel will automatically select the appropriate certificate, private key, and certificate authority bundle (CA bundle).

If you did not previously upload the private key to the server, you can copy and paste it into the private key field now.

Verify that the information is correct – especially the Domains(s) and Expiration Date fields and click on the Install Certificate button below.

If the SSL certificate was installed correctly, cPanel will give you a confirmation message. Now that you are more familiar with how cPanel's SSL Manager interface works, you can save some time when installing your next certificate by using the Manage SSL sites link directly.

SSL certificates can also be installed as the from within WHM as well, though the interface can be somewhat less intuitive than installing via a cPanel account (but it is faster if you already have the certificate, private key, and CA bundle extracted and ready for installation – or if you're just more comfortable with WHM.)

After a a Certificate Signing Request (CSR) has been generated and you have received the certificate, you would navigate to WHM Home → SSL/TLS → Install an SSL Certificate on a Domain (you can type in ssl on WHM's search bar for easy access):

From here, you would type in the domain in the Domain field and copy and paste the certificate, private key and your CA bundle into their respective fields – you should leave the IP Address field blank (for auto-discover). The certificate can then be installed by clicking on the Install button at the bottom of the page.
