What is SSL and why it is necessary for your website?

SSL stands for Secure Socket Layer. The most simple definition is that it is the standard security technology meant for establishing an encrypted link between a web server and browser. SSL is well-known industry standard which is used by millions of websites to protect the confidential data of their client. So let us discuss what Secure Socket Layer is and why it is implemented so widely in the world.

WordPress is the most popular content management system in the world. A lot of people using it to run their website, whether business based or blog based. The reason is that it gives very easy admin panel. But still lay men are concerned about things like security and SSL because they do not know much about them. If you are also going through such confusions, then this article is definitely for you.

Before diving into the mechanism of Secure Socket Layer and its purpose, lets understand the basics of browser server communication. When a user enters a URL in its browser, the browser sends request to the web server where this page is located. But this message will not go directly to the web server. It will go via many other computers. Now those computers would also be able to read the messages.

Applying SSL protocol on the website make this communication un-readable for all third parties. It ensures that all data passed between web server and browser remains private and integral and it is very very important. Many websites have to store confidential information of their visitors, like passwords, social security numbers, credit card numbers or login credentials etc. It is very easy to recognize, if a website is SSL encrypted or not. If URL is https, it is SSL encrypted and if URL is http only then this website is not SSL encrypted. If you are visitor, let me tell you that it is very unsafe to share any sensitive information here . If you are a web master, let me tell you that it is very important to created trusted environment specially if you are owning a business website.

If you want to enable your website to create SSL connection, you need to get SSL certificate. There is a pair of keys in SSL certificate. One is public key and other is private key. Both work in conjunction to establish SSL connection. Third thing it contains is “subject”, which basically is the identity of certificate or the owner of website.

In order to get the certificate, you must create a Certificate Signing Request (CSR)on your server, which would result creating both private key and public key on your server. But before that you will be asked series of questions about your website. You will send this CSR data file to Certificate Issuer Authority, and this file would contain the public key. The CA will use this data file to create data structure which matches your private key. Though CA will never see the private key. Your web server will match the SSL certificate with your private key to validate it. After receiving the SSL certificate, you will have to install it on your server.

SSL certificate typically contains following things:

  1. Your Domain Name
  2. Your Company Name
  3. Your Address
  4. Your City
  5. State & Country
  6. Expire date of Certificate
  7. Details of Certification Authority

Lets understand the working of SSL from browser’s perspective. When the user enters URL of website, the browser will request that server to provide the identification data. The server will approve it and sends the requested data along with copy of SSL. Browser sends back an symmetric session key, only is SSL certificate has not expired. When server receives it will send back the acknowledgement. Now the session will start in reliable environment.
