Generate a CSR code on LiteSpeed

To apply for an SSL Certificate, you must generate a CSR (Certificate Signing Request) code and send it to your CA for validation. The CSR contains your contact data in an encoded format. In this guide, we’ll use the OpenSSL utility to generate your CSR code. If you’ve never used it before, and aren’t comfortable entering command prompts, use the quick and easy CSR Generator tool instead.

Along with your CSR code, you will also generate your private key. These two files from the certificate key pair and cannot be separated.

  1. Run the following command to generate your private key:
    Openssl genrsa –out server.key 2048

    Note: The word “server” is the name of your private key. You can give it any name you want, but make sure you keep the .key extension.

  2. Now, run another command to generate your CSR code:
    Openssl req –new –key server.key –out server.csr

    Note: If you’ve used another name for your private key instead of “server” include it in the command. As for server.csr part, you can rename it, but make sure you keep the .csr extension.

  3. Next, the command will ask you to provide the following contact details:
    • Common Name (CN): enter the FQDN (fully-qualified domain name) you want to protect. For instance, If you have a wildcard certificate, add an asterisk (*) in front of your domain name (e.g., *
    • Organization Name (O): specify the full legal name of your company. For example, Your Company LLC
    • Organizational Unit (OU): name the department within your company requesting the SSL Certificate. For example, IT
    • Locality or City (L): write the full name of the city where your company is registered. For example, Albuquerque
    • State or Province (ST): type the full name of the state or province where your company is legally located. For instance, New Mexico
    • Country (C): provide the two-letter code of your country. For example, US. Here you can find the full list of country codes.
  4. That’s it! You’ve successfully generated your CSR code. It resides in the directory where you run the command.
  5. Locate and open the .csr file with any text editor of your choice such as Notepad. You will need to copy its content including the BEGIN and END tags and paste it during the SSL order with your SSL vendor.

Install an SSL Certificate on LiteSpeed

After your CA signs and sends your SSL certificate to your inbox, you can proceed to the installation. Here’s what you will need:

  • Your primary SSL certificate: this is the certificate issued specifically for your domain. You can find it in the ZIP folder, sent to you via email.
  • Your intermediate certificate: this certificate, or sometimes certificates help browsers identify the issuing CA. Intermediate certificates are usually stored in the .ca-bundle file. You’ll have to extract it from the ZIP folder.
  • Your Private Key: the private key is on your server, in the same directory where you generated the CSR request. If you didn’t generate the CSR on your server, you should have a copy of the private key in your email.

Please follow the steps below to install your SSL Certificate:

  1. Log into your LiteSpeed WebAdmin console
  2. On the left pane, select Listeners and then click Add
  3. In the address settings section, fill in the fields as shown below and then click Save
    • Listener Name: set a friendly name for your Listener

    • Port: the default port for HTTPS connections is 443
    • Secure: choose Yes
    • Notes: you can leave this field blank
  4. Go back to your admin console and click Listeners and under the Listener Name column, select the name you’ve just given in the previous step.
  5. Under your Listener, select the SSL tab, and in the SSL Private Key and Certificates table click the Edit button
  6. Next, you have to configure your file paths as shown below:
    • Private Key File: enter the path to your private key. Remember you’ve generated the private key along with the CSR in the same directory on your server
    • Certificate File: browse your primary SSL Certificate and add it
    • Chained Certificates: select Not Set

      Note: To install the intermediate certificates, select one of the two options below:
