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
purchase one from a Certificate Authority. You can also purchase one
directly through Plesk, as well as protect your website
with a free self-signed SSL/TLS certificate, or with a
certificate you already own.
To purchase a certificate, you need to generate a Certificate Signing
Request (CSR for short) first. Go to
Websites & Domains > your website > SSL/TLS Certificates > “Advanced Settings” > and click Add SSL/TLS Certificate.
Fill out the fields marked with the red asterisk symbol (*), such as the certificate
name (you will use it to identify the certificate in the list of all
certificates), your personal information, the name of the domain the
certificate will be protecting, and so on. Make sure that all
information you provide is correct, as mistakes may make the certificate
unsuitable and make it necessary to pay for a new one.
Note: If you want to purchase a wildcard SSL/TLS certificate, your domain
name must start with an asterisk symbol (*). For example, a
certificate generated for *.example.com can be used to secure any
subdomain of example.com.
When you have finished, click Request. This will result in the CSR
and the private key being generated and placed in your repository.
Now that the CSR has been generated, you need to provide it to the
Certificate Authority of your choice to purchase a certificate from
them. To retrieve the CSR,
go to Websites & Domains > your website > SSL/TLS Certificates > “Advanced Settings”
and click the name of the certificate you have just
generated. Scroll down to the CSR section and copy the text starting
with -----BEGIN CERTIFICATE REQUEST----- and ending with
-----END CERTIFICATE REQUEST----- (including those lines with all
the dashes) to the clipboard. You will need to provide the CSR to the…
