10 Important Difference Between HTTP And HTTPS (Tabular Form)

What is the difference between http and https?

You may have noticed URLs that begin with HTTP:// or HTTPS:// in the address bar of an internet browser. They are used to send data between the web server and the browser for a particular website. A lot of website uses HTTP. But it is better to convert your website to HTPPS as suggested by Google in 2014. Until then, only e-commerce pages have HTTPS.

HTTPS is superior to HTTP for several reasons, including improved performance, more security, and even SEO benefits. The main difference between HTTP and HTTPS is that HTTP is not secure, but HTTPS is secure and employs a TLS/SSL certificate to ensure authentication.

A website that utilizes HTTP has HTTP:// in the URL, while has a website that uses HTTPS has HTTPS:// in the URL.

The following guide will break everything down for you, not only answering these often asked issues but also providing a far better grasp of HTTP vs HTTPS in general.

What is HTTP?

HTTP (Hypertext Send Protocol) is a data transmission protocol (or set of rules for presenting data) for transmitting data over the internet. Most data, including website content and API calls, is sent using the HTTP protocol. In the OSI model, HTTP is a layer seven protocol.

HTTP is a network protocol that runs on top of TCP at the application layer. It uses hypertext structured text to construct a logical link between text-containing nodes. It’s also known as the “stateless protocol” since each command is run separately without reference to the previous ran command.

There are two types of HTTP messages. They are requests and responses messages. At first, a client(for example, a web browser) made the HTTP request to the webserver. When the server receives the request, it runs a program to process it. It then sends the client the application execution output, an HTTP response.

It makes use of Transmission Control Protocol /TCP, which is best used on port 80 and allows data packets to be sent and received over the internet.

What is HTTPs?

HTTPS stands for Hypertext Transfer Protocol Secure. It is a secure version of the HTTP protocol. It is also referred to as HTTP over TLS or HTTP over SSL. For data transport and communication, it uses port number 443.

HTTPS encrypts HTTP requests and responses with TLS (or SSL), so an attacker would see a series of seemingly random characters instead of the plaintext. As a result, HTTPS can be considered a secure variant of the HTTP protocol.

HTTPS uses the TLS (Transport Layer Security) to encrypt communications. There are two types of keys to secure communications between two devices.

  • Private key – It is used by the receiver to decrypt the encrypted text.
  • Public key – It is used for encrypting plain text.

When a client establishes a connection with a server, the public and private keys agree on new keys, known as session keys, to encrypt future communications.

If you don’t use HTTPS, any data you enter into the site (for example, your username/password, credit card or bank credentials, or any other form submission data) will be sent in plaintext and thus vulnerable to interception or eavesdropping. As a result, you should always verify whether or not the site is using HTTPS before entering any sensitive information.

HTTPS provides bidirectional encryption between the client and the server, encrypting and decrypting browser requests and server responses, protecting against man-in-the-middle attacks, eavesdropping, and message tampering.

Which is better? HTTP VS HTTPS

In this article, the difference between HTTP and HTTPS we’ve learned that HTTPS is superior to HTTP because it provides security. For websites that do not require sensitive data, HTTPS protocol is optional.
HTTPS improves our website security and helps us to improve our SEO efforts. Here are a few examples of how HTTPS can help you enhance your SEO:

Other strategies to make HTTPS better than HTTP are as follows.

  • The Google search engine will always favor Hypertext Transfer Protocol Secure (HTTPS) sites, which will boost your site’s ranking.
  • Qualified to create AMP pages for your websites, which help to speed up loading times on mobile devices and make AMP content more visible in search results.
  • Https encrypts all data sent between the server and the browser.
  • Https provides customers with the assurance that your website can be trusted and that their personal information is secure.
  • HTTPS-enabled websites have a higher conversion rate.


HTTPS has numerous advantages related to performance and, most importantly, security. All browsers strongly advise users to only trust websites that utilize HTTPS because it is the only way to protect themselves from dangers and assaults.

Also, TLS negotiation and CPU overhead are now insignificant, and we’ve noticed performance increases in several tests when people migrate from HTTP to HTTPS, as long as they’re using HTTP/2.
