SSL means Secure Sockets Layer. It is an Internet protocol used to ensure the transfer of data between a user’s browser and the website they visit is secure.
Each internet user transmits information when visiting websites. This information can often be confidential, e.g. payment details, credit card information or login credentials.
With the normal HTTP protocol, this information can be hijacked by hackers. This is where SSL or HTTPS comes into play.
Websites require an SSL certificate issued by one of the recognized certification authorities. This certificate is verified and highlighted in the user’s address bar with a padlock sign and HTTPS instead of HTTP.
How Does SSL Certificate Work?
SSL protects information by encrypting data traffic between a user’s browser and the website. When a user visits an SSL / HTTPs website, their browser first verifies if the SSL certificate of the website is valid. When everything is checked out, the browser uses the public key of the website to encrypt the data. This data is sent back to the desired server (website), where it is decrypted with the public key and a secret private key.
