Server certificate commonly known as SSL certificates or Secure Socket Layer is a digital computer file. Basically SSL’s are used by web servers and web browsers to protect their files during exchange. It contains both public key and private key. When the customer click on a secured domain, the server shares a public key with the customer and displays an encryption method and a unique session key.

The sensitive and confidential information that are exchanged between the server and the browser are encrypted, meaning the information cannot be intercepted and read by any other third party. These SSL certificates are issued by the trusted Certificate Authority. Certificate Authority (CA) has to follow strict validation process, and decides who may or may not receive an SSL certificate. Having a SSL certificate from a valid and trusted CA, means a high degree of trusted web site.

How SSL works?

Secured Socket Layer consists of two keys; Public key and Private Key.

Public key: Used to encrypt data

Private key: Used to decrypt data

Process: SSL certificate is issued for server and web site domain (web address) by a CA. When a person with the help of the browser navigates to the address of a web site certified with SSL certificate, an SSL handshake/seal appears between the browser and the server. If you click on the trust seal in the address bar, you will see additional information’s like validation period, type of SSL certificate, domain secured, and issuing Certificate Authority.
