Imagine for a moment that every piece of information you send or receive on the Internet could be intercepted. Your emails, your credit card numbers, your passwords — everything can be exposed and used maliciously. It's a scary prospect, isn't it? Fortunately, there is a solution: SSL security certificates. A Secure Sockets Layer (SSL) certificate is a digital data file that binds a cryptographic key to an organization's or individual's information. In other words, it creates a secure link between a web server and a browser, ensuring that all data transmitted between the two remains private and integral. But…
Whether you are a simple Internet user, a business or a web professional, this guide will provide you with all the information you need to understand and use SSL certificates effectively.
A Secure Sockets Layer (SSL) certificate is a digital data file that binds a cryptographic key to an organization's or individual's information. Indeed, when you install it on a server, the SSL certificate activates the padlock and the "HTTPS" protocol in the browsers to ensure a secure connection between the web server and the browser. Therefore, when you enter your data, SSL will encrypt the information between your machine and the web server.
When a browser tries to connect to a website secured by SSL, the browser asks the web server to identify itself. Next, the web server then sends a copy of its SSL certificate to the browser. The browser then checks whether this certificate is reliable. If so, it sends a message to the web server. The server responds with a digitally signed acknowledgment to begin an SSL session. Finally, the data transmitted between the server and the browser will be secure and encrypted.
SSL certificates are essential for internet security. Indeed, they simultaneously protect the transmission of sensitive data. Among the data, we can mention:
They don't just protect data. Truly, an SSL contributes to putting users in confidence in your website.
Verifying a website's SSL certificate is quite simple. Look for the padlock to the left of the URL in your browser's address bar. If you see a padlock, that means the site is using an SSL certificate. For more details, click on the padlock. You will notice on chrome browsers the mention non-secure website (if the site does not have SSL). It is important to use caution when entering your information on a website without SSL. Usually, when you enter your data on a site without SSL, there is no guarantee of security.
