What is an SSL Certificate and How Does It Work?

Before we go to “why do I need an SSL certificate,” it’s important to know what it is. Secure Socket Layer (SSL) is a protocol for building a secure connection. It ensures the safety of the data processed during online activity.

It creates a data communication channel that is encrypted. Encryption is a practice for making information only readable to authorized users.

When a user asks for data from a server, or the server wants data from the user, all of the information sent is encrypted and cannot be decoded and read by a third party.


This padlock icon indicates that your website will use a secure connection for all processes, from visitor input to server responses. As a way, it can protect data from theft and misuse.

Because SSL uses both symmetric and asymmetric encryption, breaking an SSL connection is almost impossible.

A public key is used to encrypt a message, whereas a private key is used to decode it when using asymmetric encryption. Asymmetric encryption, on the other hand, employs only public keys for both procedures.

SSL certificates depend on those two cryptographic keys to verify information like the domain and server names, and the location of the server.

How does it work? A server will first deliver a copy of its asymmetric public key. The browser will generate a symmetric session key and encrypt it using the public key once it has received it. The server will next use its private key to decrypt the message. The data transfer can take occur if the symmetric session key is the same.

What makes this safe? A session key is only valid for one session, as the title suggests. In that case, a new session key will be created for the next request.
