What is an SSL certificate?

SSL stands for Secure Socket Layer and is an Internet standard security technology used to provide an encrypted connection between a web server (site) and a browser. Such certificate allows us to use the https protocol. It is a secure connection that ensures that the information that is transmitted from your browser to the server remains private; that is, protected from hackers or anyone who wants to steal information. One of the most common examples of using SSL is protecting a client during an online transaction (purchase of goods, payment).

These certificates are currently the most common type of certificate on the Internet. Most often they are used in online stores, usually on sites where there is an order function and where the client enters his personal data.

In order to activate the ability to work with the HTTPS protocol, digital SSL certificates are just needed (you will also need a dedicated IP for a specific site).

What data does an SSL certificate contain?

The following information is stored in the certificate:

• The full (unique) name of the owner of the certificate;
• Owner’s public key;
• Date of issue of SSL certificate;
• Certificate expiration date;
• Full (unique) name of the certification authority;
• A digital signature of the publisher.

Extended validation certificates

The most expensive certifications are these. In such certificates there is a so-called “green bar” – that is, when entering a site where such a certificate is installed, a green line will appear in the address bar of the visitor’s browser, which will indicate the name of the organization that received the certificate.

Such certificates have the highest level of trust among advanced visitors to your site, since the certificate indicates that the company really exists, has passed full verification and the site really belongs to it.
