What are the differences between HTTP and HTTPS?

Hyper Text Transfer Protocol (HTTP) is a protocol, which is used for transmitting and receiving information across the Internet.
In HTTP
  • No encryption is Here
  • URL begins with “ http:// ”
  • It uses port 80 for communication.

While,
HTTPS is a combination of Hyper Text Transfer Protocol (HTTP) and SSL (Secure Sockets Layer)
Where, SSL is currently  Most frequently used  to provide security for Internet communication,
So HTTPS is more secure  for transmitting and receiving information across the Internet. 

This type of communication is used for accessing those websites where security is required. 
Like...Banking websites, payment gateway  where HTTPS protocols ar other secure protocol Must be used.

In HTTPS
  • Encryption is present Here.
  • URL begins with “https://”
  • It uses port 443 for communication.

However,
The HTTPS transaction is bit slow and More time is required for Decrypting / Encrypting.
