SSL certificates are designed for site security, namely the secure transfer of data between the client and the site. It usually works over the HTTPS protocol, which serves to protect data and guarantees the user to receive exactly the site data that he requests without the possibility of traffic spoofing.
An important point of certificates is the ability to support subdomains, such certificates are called wildcard and are more expensive, while the free Let's Encrypt certificate supports subdomains.

SSL certificates are both paid and free. Paid certificates are issued for a year or more, and also guarantee payment of compensation in case of data leakage, in the case of free certificates, no compensation is provided. Certificates are also divided according to their type: DV - Domain Validation - with domain confirmation, OV - Organization Validation - with organization and domain confirmation, EV - Extended Validation - for extended organization and domain confirmation.

If you have a website that represents a blog or a business card site, it would be a great solution to put a free certificate or a certificate with domain validation (DV). OV type certificates are recommended to be installed on social networks, large online stores and corporate sites, that is, where payment information and confidential user data are used in order to ensure the protection of these same data. If you have a website that represents a bank, a corporation, a company that is engaged in insurance or financial transactions, we recommend an EV extended confirmation certificate, such certificates are issued only to legal entities where, when issuing, the certification authority checks all the data about the company and then issues a certificate.

To order, you need to go to the SSL certificates page, select the required certificate and follow the prompts of the system. At the second stage of the order, generate a CSR code and save the private key, as you will need it when installing the certificate. Specify the domain mail for certificate verification, as an email will be sent to it after payment. After completing the entire procedure, you will receive the certificate files to your contact mail.

If you use the DirectAdmin panel - in the "Account Management" section, go to "SSL Certificates". Check the box "Insert a pre-generated certificate and key" and enter the key and the certificate itself in the indicated fields, then save. The changes will take effect within a couple of minutes.
If you use the cPanel control panel - to install the certificate, go to the "SSL/TLS" section, then click on the "Manage SSL sites.", scroll the page below, in the "Domain" drop-down list, select the site for which you want to install the certificate, write down the key, certificate and chain of certificates and click the "Install certificate" button for the changes to take effect.

Free certificates from Let's Encrypt have a validity period of 3 months and will be updated on the hosting automatically for your site. Paid certificates are valid for one year and must be manually renewed.

If you use a free Let's Encrypt certificate on hosting, it will automatically renew. We recommend that you renew the paid certificates that you purchased from us at least 14 days before the expiration date, since the certificate authority does not allow you to renew them later. "Renew" and pay the bill.
