If you already have a purchased SSL certificate from any certification authority, you should install it as follows:
1. It is necessary to convert the existing certificate file(s) using the private key with which CSR-query has been created. To do this, use the utility openssl, run the command in the console
where
- mysite.key - private domain key
- mysite.crt - SSL certificate in pem-format
- mysite-ca.crt - CA intermediate certificate in pem-format
- mysite.pfx - file to be created as a result of the command

2. When the PFX file is created, upload it by clicking the "Upload Certificate" button in the site properties.
