An SSL is a digital credential that authenticates the identity of a website and allows for an encrypted connection. SSL is an abbreviation for Secure Sockets Layer, an internet protocol security that establishes an encrypted connection between an internet server and a web browser.

SSL certificates must be added to websites by businesses and organizations to protect online payments and keep customer details private and secure.

In a nutshell, SSL secures internet connections and precludes criminals from having read or modifying information transmitted between two systems. SSL helps protect the website users visit if visitors see a padlock icon beside the URL in the search box.

How do SSL certificates function?

SSL protects transmitted data between subscribers and webpages or between two devices, making it impossible to read. It employs cryptographic techniques to clamber data in transit, preventing attackers from perusing it as it travels across the network. Identities, addresses, card numbers, and other financial details are examples of potentially sensitive data.

The procedure is as follows:

• A browser or web service attempts to link to an SSL-secured webpage (i.e., a web server).
• The internet explorer or server asks the web server to identify itself.
• In response, the web server transmits a copy of its SSL certificate to the browser or server.
• The browser or server determines whether or not it accepts the SSL certificate. When it does, it notifies the webserver.
• The web server then responds with a digitally signed acknowledgement, allowing an SSL encrypted session to begin.
• The internet explorer or web service and the server side exchange encrypted data.

Why do users require an SSL certificate?

SSL certificates are required for websites to secure user data, verify website ownership, help stop attackers from fabricating a forged website version, and express trust to users.

Suppose a website requires users to sign in and access individual information such as credit card details and sensitive information such as medical benefits or financial data. In that case, the data must be kept private. SSL certificates help keep online communication private and guarantee users that the webpage they visit is genuine and safe to share personal information with.

More importantly for businesses, an SSL certificate must be obtained for an HTTPS web link. HTTPS is the secure version of HTTP, which implies that HTTPS websites use SSL to encrypt their traffic. Most browsers label HTTP sites that lack SSL certificates as “not secure.” This sends a clear message to customers that the homepage may not be trustworthy, incentivizing businesses that have not yet migrated to HTTPS.
