SSL Certificate is a term which we frequently in our daily life but very few of us actually know what it is or how it works and since very few of us really know what an SSL Certificate is, it's quite obvious that they might not be aware of its importance or criticality in the world of computers and internet. Specifically termed as Secure Socket Layer Protocol Certificate, SSL certificate was developed by Netscape to add security factor to the transactions between browsers and web servers. The protocol employs a third party, a Certificate Authority to identify transactions at both the ends or if its difficult to understand that way, in layman's language SSL Certificate for a website is like a Passport or a Driver's License that is issued by a trusted source known as Certificate Authority. To canvas the basic understanding of an SSL Certificate through a real world example, let's imagine someone sending a mail through a regular postal system in envelope. Since it has no security factor, anyone with access to that envelope can easily retrieve its contents and if it looks valuable they might even take a possession of it or make changes to it. To cut the long story short, An SSL Certificate is something that encrypts virtual transactions or transitions or any exchange of data over the internet thus making it completely secure.
