#1 What is SSL?


SSL stands for Secure Sockets Layer, and it is the security protocol that establishes an encrypted and secure communication link between and a web browser and a web server.

#2 What is an SSL Certificate?

To create an SSL connection and activate it on your web server, you need a certificate, called SSL Certificate.

An SSL Certificate for the website makes your visitors and customers feel confident that you protect their data. It helps you in earning their trust.

#3 How to know if a website is secure?

There are three visual signs of a secure website.

  1. Check the URL of the website in the browser’s address bar whether it starts with ‘http’ or ‘https’. If it starts with ‘https’, it’s secured with an SSL Certificate. ‘s’ in the https stands for secure.                                                                                                       
  2. The close lock/padlock icon, visible in the address bar before the URL indicates a secure mode.

      3. An SSL site seal: If the website has an SSL site seal, it means some legitimate CA has verified the website and has issued the SSL certificate.

#4 What are Wildcard SSL Certificates?

Wildcard SSL Certificates can save you money and time by securing unlimited sub-domains of your main domain on a single certificate.

For example, if you want to secure your website ‘domain(dot)com’ for all the subdomains, the Wildcard SSL can secure-

  • login(dot)domain(dot)com
  • download(dot)domain(dot)com
  • newsroom(dot)domain(dot)com
  • contact(dot)domain(dot)com
  • anything(dot)domain(dot)com

#5 How does an SSL work?

When a website secured with SSL is accessed by any browser, an SSL connection is established between the web browser and the web server by a process called SSL Handshake.

There are three keys used to establish the SSL connection- public, private and session keys.

The connection encrypted with a public key can be decrypted only with a private key, and vice versa.

The SSL working process goes like this:

  • The browser connects to the secure website, and requests for the server identity.
  • The server sends its SSL Certificate copy with its public key.
  • The browser verifies the certificate that it is not expired or revoked and is from a trusted CA.
  • If everything is clear, the browser creates, encrypts, and sends back a session key to the website using the public key of the server.
  • The receiving server then decrypts the session key using its private key. It then sends acknowledgment and session key to start an encrypted session.
  • All the transmitted data between the browser and the server is now encrypted with the session key.

Factors to consider before buying an SSL Certificate-

The CA Forum has over 50 Certificate Authorities (CA) registered, you should consider the following factors before choosing an SSL Certificate provider:

  • Security Level
  • Encryption Certificate Validation Type
  • Issuance Time
  • Browser Compatibility
  • Trust Site Seal
  • Warranty Policy
  • Refund Policy
  • Support of SSL Experts
  • Period of Trial
