As soon as an SSL certificate is activated, and all validation requirements are met, the SSL certificate will be issued and sent to your administrative contact email address. When the SSL certificate is received, you are welcome to start the installation process.

The most frequent SSL tasks for Plesk panel are described below:

• Enable HTTPS connection
• Redirect HTTP to HTTPS
• SSL installation when CSR was generated elsewhere
• Retrieve a private key for multiple SSL installations
• Secure Plesk login page and mail services
• Secure webmail
