In this section we are discussing about HTTP and HTTPS.

First we have to learn what is Encryption?

Encryption is a process that encodes a message or file into an unreadable format. Encryption uses an algorithm to scramble, or encrypt, data and then uses a key for the receiving party to unscramble, or decrypt, the information. The message before encryption referred to as plain text. The encrypted, unreadable form of message referred to as cipher text.

What is HTTP?

HTTP stands for Hyper Text Transfer Protocol, which is a request-response protocol in the client server computing model. It is a widely used protocol for data transfer over the web. It is a system which successfully transmits and receives information over internet. In web browser, when we enter any web address in browser, then our browser behaves as a client and the computer system who sent the request for information acts as server. Normally, when the client request for any information to server, then it uses HTTP protocol to fetch and transfer requested information on web page.

What is HTTPS?

Now, HTTPS stands for Hyper Text Transfer Protocol Secure. Technically, HTTPS extension is similar to HTTP but uses a secure connection over network to transfer information between client and server. HTTPS uses encrypted protocol such as TLS or SSL commonly referred as HTTP over TLS or HTTP over SSL. Sometimes, users need to transmit crucial private information over network while browsing any banking sites or shopping sites. Due to its HTTPS encrypted nature,

users can successfully use highly confidential information over network such as online net banking or any shopping order.

For Example: –

Know More About HTTPS:

  • HTTPS = HTTP + Cryptographic Protocols (Such as TLS or SSL).
  • Default Port for HTTPS is 443.
  • HTTPS url begins with https://
  • HTTPS website provides valid certificate to websites which is signed by trusted authorities.
  • The letter ‘S’ in HTTPS stands for SSL i.e. Secure Sockets Layer.

What are the Main Differences Between HTTP and HTTPS?

HTTP URL begins with http://HTTPS URL begins with https://
By default, uses Port 80 for communication.Uses Port 443 for communication.
Provides no Encryption to websites.Provides Encrypted protocol to websites.
HTTP is operated at Application Layer.HTTPS is operated at Transport Layer.
It is unsecured platform to share personal information.Most secured platform for sharing personal information.
SSL certificate is not available.Valid SSL certificate is provided.
