WHAT IS SSL CERTIFICATE AND WHY DO YOU NEED IT?

Principle of SSL certificate operations.

To understand what certificate is better o choose, we should start with principles of SSL certificate operations.

1. Key. Any kind of encryption basically has a key. The same goes for SSL certificates. They are created on the basis of three keys (public, private and session).

2. Secure connection. The browser requests a certificate from the server, gets the necessary data and the public key and then generates a session key. And only after that, a secure connection is established.

At the same time, the cost of an SSL certificate will directly depend on its technical complexity. So you should first consider this moment with an orientation to the specifics of your resource. Thanks to this, you can choose SSL certificate quickly and without problems.

Types of SSL Certificates

Today, there are following types of SSL certificates:

• DV certificates - allow you to verify a domain. Suitable for personal sites (blogs, resources, business cards), as well as for small online stores.

• EV Certificates - Allows in-depth verification. Suitable for very large companies, corporations and serious organizations.

As for the price, the deeper and more thorough the checks are carried out, the higher the cost of the SSL certificate. However, such investments will pay off with the trust of visitors. Some resource owners are wondering why to buy a certificate, if you can work without it. Nevertheless, the influx of users on an insecure resource will be many times less, and SEO optimization is not so effective.
