What is SSL?

SSL (shorts for Secure Socket Layer) is a world-class security certificate, capable of establishing encrypted communication between the browser and the website server.

Currently, integrating SSL Certificate for business websites is a must, especially in the context that users are always afraid of losing their personal information to hackers and spammers.

How does it work?

Once your browser received an SSL Certificate from a website, it will send the SSL Certificate to the server that stores the technical certificates, managed by “the giants” in the digital certificates realm, such as GlobalSign, VeriSign.

 

SSL certificates create a “protective barrier” when exchanging information between websites and the user’s browser. This certificate always changes the “password” when executing the information exchange command; hackers will not be able to “break the key” even if they own the data of the technical certificate storage server.
