Note: This topic describes the old procedure present in Plesk Onyx. We recommend that you use the new one offered by the SSL It! extension in Plesk Obsidian.

If you want to secure your website with an SSL/TLS certificate, you can use a certificate you already own.

First, you need to upload the certificate. To do so, go to Websites & Domains > your website > SSL/TLS Certificates > “Advanced Settings” and click Add SSL/TLS Certificate.

Type in the certificate name (you will use it to identify the certificate in the list of all certificates), then upload it as described below:

  • If you store the certificate in the form of the *.key and the *.crt files, scroll down to the Upload the certificate files section and upload the files. If both the certificate and the private key parts of your certificate are contained in a *.pem file, just upload it twice, both as the private key and the certificate. Click Upload Certificate when you have finished.
  • If you store the certificate as text, scroll down to the Upload the certificate as text section and paste the certificate and the private key parts into the corresponding fields. Click Upload Certificate when you have finished.

Following the steps above will result in the certificate being placed in your repository. You can see a list of all SSL/TLS certificates in your repository by going to Websites & Domains > your website > SSL/TLS Certificates > “Advanced Settings”.

Now that the certificate has been generated, you need to install it. Go to Websites & Domains > your website > Hosting Settings. From the Certificate menu, select the certificate you have just generated and then click OK.
