Differences HTTP and HTTPS Complete with Functions

The difference between HTTP and HTTPS is something that you must know because it greatly affects website security.

Both are indeed the same data exchange protocol. However, the level of security and SEO performance generated by websites with HTTP and HTTPS protocols is different.

Indeed, what is the difference between HTTP and HTTPS? What is HTTPS function? Then, how does HTTPS work so that it is considered more secure?

Come on, see more in this article!

What is the Difference between HTTP and HTTPS?

Hypertext Transfer Protocol or HTTP is a protocol whose job is to send data from a web server to a browser. In other words, HTTP is the one that regulates the process for displaying the website.

However, the main problem with using HTTP is security. Because, data can be peeked by other parties when data exchange occurs.

HTTPS is a more secure version of HTTP; S represent the word Secure. HTTPS already uses an encryption or data scrambling system, making it difficult for other parties to hack.

The use of HTTPS is highly recommended, especially for websites that store customer data such as online stores or membership websites.

When the website has implemented HTTPS, the URL will be prefixed https://such as this Ipadguides website:

Furthermore, the difference between HTTP and HTTPS is in:

1. Port Usage

The first difference between HTTP and HTTPS is the use of ports to send and receive data.

HTTP uses port 80, where data communication still uses plain text, making it vulnerable to hacking.

Meanwhile, HTTPS uses port 443 which is more secure where every communication or data transfer is encrypted, so it is not easy for other parties to read.

2. Use of SSL

HTTP is a protocol that does not yet take advantage of SSL security certificates. Meanwhile, HTTPS already uses SSL/TLS (Transport Layer Secure) for data encryption.

With SSL enabled over HTTPS, when the browser requests data from the web server, the message is scrambled. That way, it can only be read properly by websites that have the specified encryption key.

The existence of SSL on a website is marked by green padlock icon in the URL bar in the browser.

3. Data Security

HTTPS uses three data security procedures, namely server authentication, data encryption, and data integrity. It is not found in the HTTP protocol.

This is the most visible difference between HTTP and HTTPS.

Server authentication can ensure the user is communicating with the correct site. So, HTTPS can avoid attacks man-in-the-middle or intruders when data exchange occurs.

Furthermore, data encryption is carried out to guard against theft and eavesdropping during data transfer.

Finally, data integrity is required for the transfer to take place. This happens because the data sent will be wrapped by the protocol, so it cannot be changed.

HTTPS has higher security. So, how does HTTPS actually work? Let’s go to the next discussion.

When there is a request for access to a website, the browser will first check whether the website is connected with an SSL/TLS certificate or not. (This is not the case with HTTP connections).

If the website has an SSL certificate, there will be an SSL handshake process related to data encryption and decryption between the server and client.

So, if the SSL certificate is valid, the session key will be generated by the server and client. That means secure data communication can be done. The browser will also display a green padlock indicator in the website URL section.

That way, the browsing process on the website has been validated for security. Do you want your website data to be protected too?

What is HTTPS Function?

There are at least three main functions of HTTPS that you need to know, namely:

1. Improve Website Security

HTTPS uses an encryption system, where data will be scrambled so that it is difficult to hack, avoid data theft, or send incorrect data.

2. Increase Website Credibility

The website will use the URL with the prefix https:// and the browser will show a green padlock icon on the website. This shows that the entire data transfer process on the website gets additional protection.

3. Positive Impact for SEO

Google’s algorithm determines that only websites with recommended SSL protection appear in search results.

That way, if you want your website to be easier to find, using the HTTP protocol is no longer an option.

To be sure, try typing certain keywords in the search results. For example “how to make dalgona coffee”. Are there still websites without HTTPS there? Of course not, huh?
