SSL Certificates, a Short Term Information Service Protocol, are used by web servers and web browsers to authenticate and verify the authenticity of a website’s SSL Certificate. In cryptography, a private key certificate, also called an SSL certificate or digital certificate, is an electronic proof of the authenticity of a private key. A SSL Certificate, usually issued with the name of the issuing company, contains information such as the issuer’s name, signature, date, fingerprint or other digitally signed data. It usually consists of two parts: the certificate of authenticity and the certificate of trust. This document proves that the private key that is being provided is one that the entity providing the certificate has authorized, and that the information provided is true and valid under the laws of the issuing country.

For instance, a business website that offers domain names may require users to provide their credit card information in order to access a particular domain name. Without the SSL Certificate, users would not be able to access this domain name. SSL Certificates not only plays a vital role in the authentication process, but they also protect the sensitive information that is sent over the internet. Hence, it is very important that the organisation that issues SSL Certificates complies with all the necessary security standards.
