Difference Between HTTP And HTTPS

The Internet operates through a variety of protocols. In this article, we will talk about the difference between two important protocols HTTP and HTTPS. Before we get a deeper understanding of HTTP and HTTPS protocols, we must first have info about what a protocol is.

What is the Protocol?

A protocol is a set of rules that we use to achieve specific goals. For example, you might think of the protocol as a specific language. Every language has its own grammar and vocabulary. If two people share a common language, they can communicate effectively.

As in the example above, if computers (or other devices) want to communicate with each other, they must follow predefined communication rules.

Currently, various algorithms are used for communication in the Internet environment. But we can say for sure that the most important of these protocols are HTTP and HTTPS.

Do You Know the Difference Between:

What is HTTP?

HTTP stands for Hypertext Transfer Protocol or Hypertext Transfer Protocol. This protocol provides rules and standards that govern how information is transmitted over the Internet. HTTP sets standard rules for communication for browsers and servers.

HTTP is a network application layer protocol based on the TCP protocol. It uses structured hypertext to establish logical communication between nodes containing text. Also known as a stateless protocol. Each command is executed separately, without the need to refer to the execution of the previous command.

What is HTTPS?

HTTPS stands for HyperText Transfer Protocol Secure. This protocol is a much more secure version of HTTP and uses port 443 for data exchange. This protocol enables secure transmission by encrypting all communications using SSL. HTTPS is a combination of SSL or TLS and HTTP protocol. This protocol provides secure and encrypted authentication of a network server.

HTTPS also allows an encrypted connection between the browser and the server. This protocol provides two-way information security. This prevents the theft of sensitive information. In the HTTPS protocol, SSL exchanges are performed using a key-based encryption algorithm. This key is 40 or 128 bits long.


Difference Between HTTP and HTTPS

  1. HTTP does not use the data encryption mechanism, while HTTPS uses SSL or TLS protocols to secure communication between the server and the client.
  2. HTTP does not use data hashtags, while HTTPS will have the data before sending it and return it to its original state on the receiver side.
  3. HTTP does not require a certificate or domain validation, but HTTPS requires a certificate to use SSL.
  4. HTTP runs at the network application layer, while HTTPS works at the transmission layer.
  5. HTTP runs on port 80 by default, while HTTPS runs on port 443.
  6. HTTP transmits data in plain text, while HTTPS uses encrypted text.
  7. HTTP is faster than HTTPS because HTTPS uses computing power to encrypt the communication channel.
  8. HTTP URL starts with http: // but HTTPS URL starts with https: //.
  9. HTTP is suitable for websites that are designed to display information only, such as blogs, while HTTPS is suitable for websites that collect personal and sensitive information such as national numbers and bank card numbers.
  10. HTTP has no effect on site rankings in search results, but HTTPS has a positive effect on this.

Benefits of HTTP

  • HTTP can be implemented with other protocols on the Internet, or on other networks.
  • HTTP pages are stored on a computer or cache, making them easier to access.
  • HTTP is platform-independent, which makes it possible to exchange information across different platforms.
  • No need for runtime support.
  • It is effective against firewalls, so it can be used in global applications.
  • It is not connection-based, so it will not overload the network.

HTTP Restrictions

  • Privacy is not guaranteed, as anyone can read the information.
  • Information integrity is a big problem, because someone may be manipulating the content, and therefore the
  • The HTTP protocol is not secure, because it does not use encryption methods.
  • Communication security is not guaranteed, as it is possible to steal your username and password.

Benefits of HTTPS

  • In most cases, websites running on HTTPS will take you to a secure HTTPS connection, even if you try to enter the site by entering HTTP: //.
  • Allows users to conduct secure e-commerce transactions such as online banking.
  • SSL technology protects users and gives them a sense of security.
  • An independent entity verifies the identity of the holder of the SSL certificate, so each certificate contains unique information and authentication of the holder.

HTTPS Restrictions

  • The HTTPS protocol cannot prevent the theft of sensitive page information stored in the browser cache.
  • Data on the SSL protocol is only encrypted during data exchange over the network, so HTTPS is unable to clear text stored in the browser’s memory.
  • HTTPS can cause network overload and over compute.

Differences Between SSL / TLS Certificates Used in the HTTPS Protocol

Domain Validation: This certificate verifies the ownership of the certificate applicant on the domain. Confirmation of personal ownership of a domain can take between minutes and hours.

Organization Validation: The certification body checks not only the authenticity of ownership of the domain but also the identity of that person. This means that the domain owner can be asked to provide proof of identity.

Extended Validation: This type of certificate requires the highest level of authentication. Verification of this certificate requires verification of domain ownership, authentication, and registration.

How to Migrate from HTTP to HTTPS

Here are the simple steps, just follows:

  • Buy an SSL certificate. It is best to buy an SSL certificate from the company that provided your hosting, as they can ensure that it is enabled and installed correctly on your server.
  • Install the SSL certificate on your hosting account.
  • Before finalizing HTTPS, make sure that all the links within your site have a valid HTTPS URL.
  • Having a number of HTTP links and a number of HTTPS links may confuse your site audience as well as problems loading some components of web pages. This issue affects SEO. The site also has a negative impact.
  • Use 301 Redirect to help search engines notice the change in the URL of your links and redirect incoming traffic to a new address.

Final Words

In this article, we have tried to review how protocols work on the Internet and two important HTTP and HTTPS protocols. As mentioned, using the HTTPS protocol on a website can be very useful. We also talked about the impact protocols on-site security, user trust-building, and SEO optimization.

Compared to HHTP and HTTPS protocols, HTTPS is definitely a winner because of the above advantages and features. If you still use HTTP, immediately switch to HTTPS.
