This article describes how to generate and install a self-signed SSL certificate in Plesk.
Plesk is no longer included with new hosting.com plans, but it is still available on legacy Managed WordPress accounts. You can install Plesk manually on unmanaged VPS and Dedicated servers.🚧 ImportantHosting.com servers support Server Name Indication (SNI), which means SSL certificates do not require a dedicated IP address to work correctly. For more information about SNI support at hosting.com, please see this article.

Installing a self-signed certificate

You can install a self-signed SSL certificate on your hosting.com account for testing and development purposes.
️ WarningUsers receive warning messages in their browser when they try to access a web site secured by a self-signed certificate. This is because a trusted Certificate Authority has not signed the certificate. Let’s Encrypt certificates are readily available for Plesk accounts and are a trusted Certificate Authority in most browsers. For more information about Let’s Encrypt certificates, please see this article.
