SSL Certificate – Let’s Dig A Bit!

SSL Certificate stands for Secure Sockets Layer certificate and is a standard security technology for formation of an encrypted link between a client and the server- a web server (website) and a browser or a mail server and a mail client such as Outlook.

SSL lets sensitive information such as social security numbers, debit and credit card number and login details to be transmitted without any breaching and securely.

It is a norm generally- when data is sent between web servers and browsers, it is sent in plain text- leaving one susceptible and vulnerable to hacking and more. If a hacker or web attacker is able to capture all data being communicated or sent between a web server and browser they can easily see and use these information.

Technically speaking, SSL is a security protocol and as a protocol denotes how an algorithm must be used; in this case, the SSL protocol regulates encryption details for data being transmitted and the link, both.

SSL easily safeguards endless number of peoples’ data over the internet every day, especially during the process of online transaction or when exchanging confidential information.

SSL secured websites have URL like this (Green address bar/lock icon).

Where Do Certificates Drop In?

ssl-certificate-lets-dig-a-bitAll browsers are built with the capacity of interacting with secured web servers using the SSL protocol. However, the server and the browser need something called SSL Certification/Certificate to be able to establish a secure connection.

How Does SSL Certificate Work?

SSL Certificates are laced with a pair of keys; a private and a public key and they work together in tandem to create or establish an encrypted connection. This certificate also contains what is called the ‘subject’- an identity of the website owner/certificate.

In order to get a certificate, one must apply for a Certificate Signing Request (CSR) on their servers. This process further establishes a public and private key on your server.

The CSR data file which you send to the SSL certificate issuer and what is called a Certificate Authority that possesses the key.  The certificate authority then uses the CSR data file to establish a data structure to match your private key minus compromise of the key and the CSR never sees the private key.

Once an SSL Certificate is received, you can install it on your server.

How Does The SSL Certificate Create A Secure Connection?

When a web browser (Google Chrome, Mozilla Firefox, Internet Explorer and more) tries to access a website which is SSL secured/safe, then the web server and the web browser launches an SSL connection with the help of a process called an SSL Handshake (This SSL Handshake is not visible to users and occurs straightaway)

  • Browser connects to a web browser (website) secured with SSL (https) and it initiates the server be recognized directly and itself.
  • Server sends across a copy of SSL certificate which also includes public key of the server.
  • Browser checks the certificate root when pitted against a list of trusted CAs and that the certificate is unrevoked, unexpired and whose common name is valid for the website it is connecting to. If the browser is able to trust the certificate, then it encrypts, creates and sends back a symmetric session key while using the server’s public key.
  • Server and Browser now encrypt all transferred data with the session key.
