HTTP Vs HTTPS

HTTP offers set of rules and standards which govern how any information can be transmitted on the World Wide Web.

HTTP provides standard rules for web browsers & servers to communicate.

HTTP is an application layer network protocol which is built on top of TCP.

HTTP uses Hypertext structured text which establishes the logical link between nodes containing text. It is also known as “stateless protocol” as each command is executed separately, without using reference of previous run command.

HTTPS stands for Hyper Text Transfer Protocol Secure. It is highly advanced and secure version of HTTP.

HTTPS allows the secure transactions by encrypting the entire communication with SSL. It is a combination of SSL/TLS protocol and HTTP. It provides encrypted and secure identification of a network server.

Difference between HTTP and HTTPS are:

	HTTP	HTTPS
Protocol	It is hypertext transfer protocol.	It is hypertext transfer protocol with secure.
Security	It is less secure as the data can be vulnerable to hackers.	It is designed to prevent hackers from accessing critical information. It is secure against such attacks.
Port	It uses port 80 by default	It was use port 443 by default.
Starts with	HTTP URLs begin with http://	HTTPs URLs begin with https://
Used for	It’s a good fit for websites designed for information consumption like blogs.	If the website needs to collect the private information such as credit card number, then it is a more secure protocol.
Scrambling	HTTP does not scramble the data to be transmitted. That’s why there is a higher chance that transmitted information is available to hackers.	HTTPS scrambles the data before transmission. At the receiver end, it descrambles to recover the original data. Therefore, the transmitted information is secure which can’t be hacked.
Protocol	It operates at TCP/IP level.	HTTPS does not have any separate protocol. It operates using HTTP but uses encrypted TLS/SSL connection.
Domain Name Validation	HTTP website do not need SSL(Secure Socket Layer).	HTTPS requires SSL certificate.
Data encryption	HTTP website doesn’t use encryption.	HTTPS websites use data encryption.
Search Ranking	HTTP does not improve search rankings.	HTTPS helps to improve search ranking.
Speed	Fast	Slower than HTTP
Vulnerability	Vulnerable to hackers	It Is highly secure as the data is encrypted before it is seen across a network.
