What is SSL certificate?

SSL Certificate explained in detail

SSL certificates, short for Secure Socket Layer, were developed by Netscape to secure online transactions between web servers and web browsers. SSL certificates can help protect an online user’s banking details, login credentials, email addresses, and other confidential information with first-rate encryption strength, keeping it nice and secure and away from the ruthless eyes of hackers.

An SSL certificate is issued by a Certificate Authority (CA). In this model, the CA is the trustworthy third party that will authenticate both ends of the transaction. An SSL certificate binds together a domain name, host name and server name along with the organizational identity and location.

Organizations that intend to secure their websites with SSL certificates need to install these digital certificates onto their web servers. This helps them secure their online sessions with web browsers. Depending on the type of SSL certificate chosen, an organization will need to go through various levels of validation.

After installing an SSL certificate successfully, a website connection with an ”https://” URL is established, which leads the web server to establish a secure connection with the web browser. Browsers then inform visitors that the website is SSL-Secured, with the help of several visible trust indicators, depending upon the type of SSL certificate:
