What is SSL and SSL Certificate?

Secured Socket Layer (SSL) is the technology that makes sure data between two machines (in our case – a browser and a server) is transmitted securely in an encrypted connection (HTTPS).

An SSL Certificate is a digital certificate that confirms the identity of a website.

To implement SSL on your website, you will need to get an SSL Certificate from a SSL Certificate Provider, aka. Certification Authority.

How SSL connection works

The following diagram shows how data is transferred through an SSL connection.

How SSL works

  1. A user access a HTTPS website
  2. User’s browser requests a secure SSL connection from the server
  3. The server responds with a valid SSL certificate
  4. The secure connection is now established
  5. Data is encrypted and transferred

How can I tell if a website has SSL connection?

The use of an SSL Certificate on a website is usually indicated by a padlock icon on web browsers and the website address will show HTTPS. In some cases, a green address bar is shown.

If a SSL certificate is not recognized by the browser (or it does not pass certain checks), the browser will display a warning to the visitor.

Things to Know Before Purchasing a SSL Certificate

Implementing HTTPS for Better Site Security

There are a number of ways you can get protected an SSL certificate and implement HTTPS to your websites. These include using a free one by Let’s Encrypt, making use of Cloudflare’s automatic SSL coverage, or even buying one depending on your requirements.

To make sure that your SSL purchase process goes smoothly, we recommend that you get the following things ready.

  • A unique website IP address
  • A certificate signing request (CSR)
  • Updated and correct WHOIS record
  • Validation documents for your business/organization

Types of SSL certificate

There are three types of SSL certificate – Domain Validated (DV), Organizational Validated (OV), and Extended Validated (EV).

Domain Validated (DV)

  • Implementation time & costs – It takes few minutes to few hours. The fee is minimal.
  • Price range – Starting at $6 per year.

Telling visitors that the connection between the browser and the website is encrypted. is using Extended Validated (EV) SSL. Company with EV SSL went through extensive validation that confirms that the business entity is legal. In some browsers, the company name will be shown on the address bar in green color.
