What is SSL and How Does it Work?


As an increasing number of businesses are offering online services and transactions, website security has become a priority. With a lot of businesses processing sensitive information, they need to ensure the privacy and security of that information.

Today, there is a broad range of security tools to help site owners ensure the safety of their site and data. An SSL Certificate is a crucial tool that provides secure communication between your web server and the user’s device. Today, we will talk about SSL and understand how it works.

What is an SSL Certificate?

You can secure online transactions using an encryption process, and an SSL certificate is an essential component of this process. You can think of an SSL certificate like a passport that identifies you and allows confidential communication with your users. SSL or Secure Sockets Layer is a protocol that allows two devices to communicate with each other using encryption.

Traditionally, SSL certificates were necessary for websites that exchanged financial information; most other sites didn’t worry about having them. However, in recent years, with an increase in the number of cyber-attacks, most websites have started installing SSL certificates on their sites.

How does SSL work?

Here is a quick look at how an SSL certificate works:

  1. A user tries to connect to your SSL-secured website.
  2. It sends a request to your webserver to identify itself.
  3. Your server sends a copy of its SSL Certificate to the user’s browser.
  4. The browser checks if the SSL certificate is trustworthy and sends a confirmation to your server if the certificate checks out.
  5. The user’s browser digitally signs an acknowledgment and sends it to your server to start the encrypted session.
  6. Your server and the user’s browser can now start sharing encrypted data.

Do I need an SSL Certificate?

An SSL Certificate offers a range of benefits like:

  1. Better SEO ranking since Google prefers websites with one
  2. A safer experience for your clients
  3. Boost trust and improve conversions
  4. Create a safety net for both customer and site data
  5. Encrypt the communication to and from the server
  6. Boost the security of applications

There are three types of SSL certificates available:

  1. Domain Validation (DV) Certificate validates domain ownership only. However, it does not show the details of the organization.
  2. Organization Validation (OV) Certificate validates the organization along with the domain.
  3. Extended Validation (EV) Certificate is a favourite of most users since it offers the most comprehensive validation checking.

Summing Up

In today’s times, with an increasing number of hacking attempts, encrypting the communication between your server and the users is a must. By installing an SSL Certificate, you can ensure that a hacker can’t gain easy access to the sensitive information from your server. It offers a sense of protection to your users and helps you develop a brand that people can trust. If you have not yet installed an SSL Certificate, get one today!
