If we talk technically, SSL is a security protocol, which creates an encrypted link between your web browser and web server (web browser i.e. your computer or mobile internet browser and web server i.e. whatever website you are opening , its server) so that whatever data is being shared between the two, or communication is taking place, it remains safe, no one can steal or hack it.

Just as online transactions are done nowadays, in which we put our credit or debit card information online, in such a way, SSL is the only protocol that keeps the information, data or communication shared by us secure. Although SSL has now been replaced by another updated protocol (TLS) Transport Layer Protocol, it is still known as SSL, and its functionality is almost the same.

How ssl works

Above you have read What is SSL, let us now know, how SSL works. The job of SSL Protocol is to ensure that any type of data being shared between the browser and the website or email server and email client is unreadable, that is, which cannot be read or understood by anyone in the middle, so let’s understand. That’s how all this happens.

When you access a website that is protected by SSL on your Internet browser, your browser and the web server use a process called SSL/TLS to establish or create an SSL connection. It’s called a handshake.

In this process, the necessary information related to each other is shared between the client and the server i.e. your web browser and the web server, in which the information of the SSL certificate of both as well as the public key of the server is also shared, after which the client The server’s SSL certificate is verified by a (CA) certified authority, and if all is found to be correct, the process proceeds. While this process between the browser and the webserver may seem lengthy for you to read, it is actually very fast, taking only a few milliseconds to complete.

In this process, the client further prepares a session key, and encrypts that key with the server’s public key and sends it to the server, after which the server decrypts that encrypted session key received by the client with its private key, and Then sends an acknowledgment encrypted with that session key back to the client, so that further encrypted session can be started.

So in this way the entire data shared between the browser and the web server is encrypted and decrypted by the Session Key. Session Key which is valid only for a specific session, and as soon as the session ends, the work of that specific key ends, similarly when a new session starts, a new Session Key is prepared.

Let us tell you that any data which is encrypted by Public Key, then it can be decrypted only and only by its Private Key. For more information about this, you can read our post on Public Key Infrastructure.
