Generate CSR in Plesk

First, you need to lay the foundations for your SSL installation. The CSR (Certificate Signing Request) code is required during the SSL verification and validation. You can generate the CSR code for your domain from your Plesk dashboard. Here is how you can do it on Plesk

  1. Log into your Plesk dashboard
  2. From the left pane, select Domains (Plesk Onyx) or Website and Domains (Plesk 12)  and locate the domain name you want to secure
  3. From the main central menu click on SSL/TLS Certificates (Plesk Onyx) or Secure Your Sites (Plesk 12)
  4. On the new page, click Add SSL/TLS Certificate
  5. Now, you have to submit a list of parameters. Make sure the info about your company is up to date
    • Certificate Name: Enter an easy-to-remember name so you can identify this certificate from other similar files
    • Bits: From the drop-down list, select the encryption level for your certificate. We recommend the standard 2048
    • Country: From the drop-down list indicate your company’s country of origin
    • State or Province: Enter the full name of the state where your business is legally located. For instance, Florida
    • Location (city): Specify the city where your organization is registered. For example, Miami
    • Organization name (company): If you bought a Business Validation or an Extended Validation Certificate, type the legal name of your company (e.g. GPI Holding LLC) For Domain Validation (DV), enter your full name, or your website’s name
    • Organization department or division name: If you’re not sure, type “IT” or “Web Administration”. For a DV certificate, enter NA (not available)
    • Domain Name: Submit the FQDN (Fully Qualified Domain Name) of the website you want to encrypt. For example,

      Note: If you have a Wildcard certificate, the domain name must start with an asterisk. For example, *

    • Email: Provide a valid email address so that the CA can verify the domain ownership
  6. Double-check the information you’ve just provided, then click Request. Plesk will now generate your CSR code and private key
  7. To view both codes, on the next page, from the list of certificates click on your certificate name
  8. Now, you can copy the CSR code (including the —–BEGIN CERTIFICATE REQUEST—– and —–END CERTIFICATE REQUEST—– tags) and use it during your SSL order process. As for the private key, you will use it later during the SSL configuration.

Install an SSL Certificate on Plesk Onyx

  1. Log into your Plesk account
  2. If you’re a Server Administrator or Reseller, navigate to Domains section, select the domain name you want to protect, and click SSL/TLS Certificates. If you have a default customer account, go to Websites and Domains, choose the relevant domain name, then click on SSL/TLS Certificates. Further steps are identical for both groups of users
  3. Click on the SSL certificate name for which you generated the CSR code and private key
  4. On the next page, you need to upload your certificate files. Here you have two options: upload the files directly, or copy the files’ contents in the corresponding fields and upload them in text format. No matter what option you pick, make sure you have all the necessary files. You will the SSL certificate (.crt) and the optional CA certificate (.ca-bundle) for older browsers’ versions. If you didn’t generate the CSR in Plesk, you will also need the private key (.key) file. When you have finished, click Upload Certificate
  5. You will receive a message about the successful installation. Next, you have to assign your SSL certificate to the hosting services
  6. Click on Hosting Settings from the main dashboard of your domain, and from the Certificate drop-down list, select your SSL certificate. Click OK
  7. Another message will confirm the successful SSL configuration
  8. To force the HTTPS connection, return to the previous step (6), tick the Permanent SEO-safe 301 redirect box, then Apply > OK.

  1. Access your Plesk Panel
  2. Navigate to the Websites & Domains tab and choose the domain you want to secure
  3. Click Secure Your Sites
  4. Select the SSL certificate that you created during the CSR generation.
  5. Next, in the Upload Certificate Files section click Browse to upload the primary Certificate and CA certificate (CA Bundle) from your local machine. Once you’ve selected both files, click Send Files. Alternatively, you can copy and paste the certificates’ content into the corresponding boxes under Upload the certificate as text, and then click on Send Text. Please note that you may also need to upload your Private Key if you didn’t generate it on Plesk along with the CSR.
  6. Go back to the Websites & Domains tab and click on Hosting Settings next to the domain in question.
  7. On the next page, in the Security section, select your certificate from the drop-down menu list and check the SSL Support option
