TLS certificates
Digital certificates are the cornerstone of the security provided by TLS protocols. They encrypt connections between the user's browser and the server where sensitive data is being sent and stored.
The second, no less important feature of the TLS protocol, is confirmation of authenticity of the server we are communicating with. Web browsers help us to authenticate the other side, either by clicking on the "lock" in the address bar, or by a company name clode to the adress bar on wesite with an EV certificate. We can use certificates for an opposite authentication - client to server.

Why should we use a TLS certificate?
TLS certificates installed on a server are used to secure data transfer against "eavesdropping" and confirm the authenticity of the server - owner of the certificate. TLS certificates should be used by everybody who collects sensitive information (personal data, passwords, credit card numbers), transfer and work with such data. A trusted certificate should be used by everybody who wants to tell the message YES, this website is run by our organization and the authenticity is confirmed by our certificate, which is issued by a trustworthy authority.
What is a TLS protokol
TLS (Transport Layer Security) is a noncommercial open protocol and currently one of most popular methods of securing data transfer on the Internet between a website and a browser (user). Nowadays the most recent TLS protocol is TLS 1.3, which is a standardized protocol with its own RFC.
The TLS protocol uses digital certificates to encrypt data in transfer and for server authentication. The fact that we are connected to a website secured by TLS protocol can be identified by the address in the browser, which contains the letter "s", eg https://www.sslmarket.com/. Browsers show a lock icon showing use of the encryption.
TLS certificate encryption is based on asymmetric encryption, where each communicating party has two encryption keys - public and private. The public key can be published, and if the public key encrypts the data, we can be sure that only the owner of the public key can decrypt the data with a matching private key. On the other hand, if data is encrypted with a private key, only the public key can decrypt it. Applied to the TLS certificate, public keys in TLS certificates are used for encryption and private keys on server for decryption.
