HTTP and HTTPS: Definition, Differences, and Functions

HTTP and HTTPS are commonly encountered when accessing website addresses. They are located at the beginning of those address rows. These two protocols certainly have their own differences even though they only differ by the letter 'S'.

As someone actively involved in the internet world, you must already know and understand both of these protocols very well. However, for those of you who are still unfamiliar, no need to worry because this article will discuss them from their definitions, differences, to their functions!

Getting to Know HTTP and HTTPS: What is HTTP?

HTTP stands for Hypertext Transfer Protocol which protocols the application layer network where its development is aimed at driving the process of delivering information - such as files, documents, images, audio, video - from one computer to another.

You should know that the HTTP protocol usage correlates with hypertext. Therefore, it is not surprising if it often fetches resources from a link - a type of 'file' that acts as a 'reference' to directories or other files.

This protocol contains collective commands that are in network communication. The communication itself is between the client computer and the web server and vice versa.

In this communication, the client computer makes requests by accessing the URL (domain) or IP Address. Then, the web server manages that request by adjusting the input code.

Getting to Know HTTP and HTTPS: What is HTTPS?

HTTPS stands for Hypertext Transfer Protocol Secure which is a development result of HTTP. Like before, HTTPS also protocols communication or information transfer within the internet network.

Currently, HTTPS is a format of internet network protocol that ensures security and validity. HTTPS has the ability to protect the integrity and confidentiality between user computers and sites.

Through the use of HTTPS, data or information sent from websites to visitors cannot be intercepted by users or other parties. This is due to the enhanced security updates.

Not only that, HTTPS also makes it difficult for others to hijack the content or data transferred through the website to visitors. This indicates that what you obtain from the web is less likely to be stolen or hijacked by others.

Differences between HTTP and HTTPS

Although they may seem similar and only differ by one letter at the end, HTTP and HTTPS have their own respective differences. Some of them include aspects as listed and briefly explained below:

Data Security

Data transmission through the HTTP protocol does not provide security guarantees for clients or servers. As a result, this triggers many crimes, such as data hacking.

HTTP also has a high risk of data dissemination to unknown subjects. This is different from HTTPS which has a collaborative security transmission protocol.

It is not surprising that website developers prefer the HTTP protocol. Speaking of HTTPS data security protocol, it uses 3 procedures for data security. Below is an explanation:

Server Authentication

The existence of this protocol causes the client to trust that the data or information accessed belongs to the target server. Generally, this process applies client name and password validation.

If there is an error during the validation process, the consequence is automatic rejection of the client's response by the server.

Data Confidentiality

Accessing server data by clients through a website browser will not be understood by other clients. This is supported by the existence of the term 'data encryption'.

You should know that data encryption methods work with a difficult level of understanding, requiring special codes to read.

Data Integrity

Other users will not be able to make changes to the data being transmitted by the client. This is due to the existence of the Message Authentication Code validation process.

So, the MAC requires a message and a secret key where only the sender and receiver of the message know. This process ensures that the message recipient enters the same secret key.

SSL

In essence, client and server communication protocols regularly apply the HTTP concept. If you want to use the HTTPS protocol, an SSL or Secure Socket Layers certificate is required.

In the HTTPS protocol, there are 6 types of SSL that can be used by website developers. This usage can display a padlock icon in the URL address bar of a website.

With the presence of a padlock icon in the HTTPS protocol URL, the level of trust of website visitors can increase, knowing that SSL can secure important data, from identities to passwords.

Port Usage

In HTTP, the utilized port is type 80. This type is useful for web server connectivity with clients. Then, for HTTPS, port 443 is required for network connectivity.

Differences in Function between HTTP and HTTPS

Essentially, the functions of HTTP and HTTPS are the same. As explained earlier, both protocols are used for data transfer and communication within the internet network. There are actually other functions. Here are some of them:

HTTP Function

HTTP functions as a command format regulator. For example, when you input a domain URL in a browser, that URL transforms into a command on the web server to provide information or data to the destination website.

HTTPS Function

Since HTTPS is an update from HTTP, its function is data security. Therefore, the additional double security system in user information or data can be more reliable when browsing websites.

Benefits of Using HTTPS

Although HTTP and HTTPS are similar, HTTPS is still superior to HTTP. This is because of its guaranteed security facilities. Therefore, it is not surprising that HTTP users are switching to HTTPS now, as there are many benefits such as:

Providing a More Secure Experience

This is the main advantage. It is clear that HTTPS has more reliable security than HTTP, as it contains encryption systems that allow for a more secure website browsing experience.

Boosting Dwell Time on Websites

If a website does not use HTTPS, there will be an 'insecure' warning that discourages visitors from browsing longer on that site.

Therefore, by switching to HTTPS, it can be ensured that dwell time will increase. There will be no 'insecure' warning, so visitors will trust to browse longer.

Having Faster Loading Time

In addition to ensuring security and increasing dwell time, the HTTPS protocol also helps to speed up loading time. This is more optimal than just reducing image sizes and similar efforts.
