HTTP vs HTTPS: Differences and Functions of these protocols

HTTP vs HTTPS: Differences and Functions of these protocols

In this article, we will discuss the differences between HTTP vs HTTPS, of course they will be fully discussed in this article, starting with understanding and differences, all of which will be discussed in depth in this article.

Maybe some of you have heard the term now that one of the benefits of using HTTPS is on the SEO side, actually the benefits and advantages are not only on the SEO side, there are other advantages, like what? Check it out below!

What is HTTP and its functions?

HTTP stands for Hypertext Transfer Protocol . HTTP is a protocol that provides usability for communication between different systems, one of which is to send data from a web server to the browser that we usually use to display the web pages that we open.

We can find this HTTP when you access a website at the beginning of the domain. The disadvantage of http is that the data sent from the browser that we use to the server is not adequately protected, so there is a risk that it will be misused by irresponsible people.

So how to fix it? Of course, to overcome this, you have to use a more secure version, namely HTTPS, where the letter S represents the word secure which means secure.

What is HTTPS and its functions?

HTTPS stands for Hyper Text Transfer Protocol Secure. HTTPS is the most secure and advanced version of HTTP. HTTPS uses port # 443 which has a function like communication with SSL. It is a combination of the SSL / TLS and HTTP protocols. Therefore, it can provide encrypted identification and network server security.

HTTP also allows you to establish a secure encrypted connection between the server and the browser. Therefore, by providing two-way security, it helps protect information that has the potential to be stolen.

In the HTTPS protocol, SSL transactions are also assisted by a key-based encryption algorithm. This key has a strength of 20 to 128 bits. Well, now that you know the respective meanings between HTTP and HTTPS, we will now describe the differences we found between the two.

Fundamental differences between HTTP and HTTPS

  • HTTP does not have a security mechanism to encrypt data, while HTTPS provides SSL or LS digital certificates to secure communication between the server and the client.
  • HTTP operates at the application layer, while HTTPS operates at the transport layer.
  • HTTP works by default on port 80, while HTTPS works by default on port 443.
  • HTTP transfers data in plain text, while HTTPS transfers data in ciphertext (ciphertext).
  • HTTP is faster than HTTPS. Why ? Because HTTPS uses computational data to encrypt the communication channel.

Advantages of using HTTP

  • HTTP can be implemented using other protocols on the Internet or on other networks.
  • HTTP pages are stored in computers and Internet caches so that web pages that use HTTP when accessed are much faster.
  • Platform independent allowing cross-platform portability.
  • You do not need Runtime support.
  • It is not connection oriented, so there is no network overhead to create and maintain state and session information.

Advantages of using HTTPS

  • Generally, sites equipped with HTTPS will have automatic redirects. Therefore, even if we type the website address with http: //, it will be automatically redirected to https: //.
  • Users can safely conduct e-commerce transactions.
  • SSL technology that complements HTTPS can protect users and can also build trust.
  • An independent authority verifies the identity of the owner of the certificate. Therefore, each SSL certificate contains unique and authenticated information about the owner of that certificate.

HTTP restrictions:

  • There is no privacy for anyone to view the content.
  • Data integrity is a big problem because someone can change the content. That is why the HTTP protocol is an insecure method, because encryption is not used.

HTTPS restrictions:

  • The HTTPS protocol does not stop stealing confidential information on cached pages in the browser.
  • SSL data can only be encrypted during a transition on the network. That means you cannot delete text in browser memory.
  • HTTPS can increase computational overhead as well as network overhead.

Types of SSL (Secure Socket Layer)

Here are some SSL certificates you should know about:

  • Extended Validation Certificates (EV SSL)
  • Validated Organization Certificates (OV SSL)
  • Domain Validated Certificates (DV SSL)
  • Wildcard SSL Certificate
  • Multidomain SSL Certificate (MDC)
  • Unified Communications Certificate (UCC)

An explanation of the types of SSL in the article on SSL types and their uses.

What type of SSL is suitable for my website?

Domain Validation The SSL type can be used for personal blogging or website needs to provide security guarantees when transacting between websites and browsers.

What about commercial, business, e-commerce or other websites? For this type of website, you can use OV type SSL (Organization Validation or Extended Validation SSL, which is the right choice.


Based on the discussion above, using HTTPS is very important if you prioritize the security side of the website and give your site visitors the confidence of your security. Having a secure website is one of the keys to success in the online world.

You must remember the following:

  • If a website that only comes with HTTP does not use HTTPS, the browser will send all the information as plain text to the website’s server. If someone sees the website traffic, they can see the scattered information.
  • Unlike websites that are equipped with an SSL certificate and use HTTPS, the traffic on the web is encrypted. This encryption is essential to securely collect confidential information from any customer.
  • Google also prioritizes websites that are equipped with HTTPS, which means that Google prefers websites that are equipped with HTTPS, so that your website will be indexed more easily and you will have a higher probability of being in the first position of the Google searches.
