How HTTP And HTTPS Works


HTTP stands for Hypertext Transfer Protocol. HTTP allows their users of World Wide Web to transfer their information on web pages. It is a primary technology protocol that allows linking and browsing on web. For the collection of credit card information and number on HTTP, you are broad casting this information openly on internet  then there must be a possibility that hacker stole your credit card information. Main key points of HTTP are:
  • Start URL with http://
  • HTTP uses at port 80 for communication.
  • HTTP encrypts data as a plain text.
  • Certificates are not required.
  • Data is openly transferred not encrypted.
  • HTTP is unsecured.
  • It operates on application layer.


HTTPS stands for Hypertext Transfer Protocol with secure sockets layer (SSL).  HTTPS are such primary developed protocol that transfers data in the form of codes on web. It encrypts data and receives through Secure Sockets Layer. For the working of HTTPS certificates are required that often comes free or sometimes you should have to pay for certificate. There is another method of obtaining certificates is admin site that make these certificates and upload in the browser. It is more secure way to send the request from user to server. The communication through HTTPS is very secure because data is encrypted between two users and no the other one can even know about it. This type of communication is used to access those kinds of websites where the security is required. For example banking sites, shopping sites etc
Main key points of HTTPS are:
  • Starts URL with https://
  • HTTPS is used port 443 for communication.
  • Data is encrypted.
  • Certificates are required for security reasons.
  • It is secured then http.
  • HTTPS operates on the transport layer.
When you want to link on web forum, always try to link them with full server URL that includes https:// designation. This will always ensure to be secured.
When you run your website on https:// it should slow down the connection. For this some SSL provider may charge you to be secured.  You should need to be securing those pages where the data is collected.
