What is The Difference Between HTTP and HTTPS?

HTTP vs HTTPS - this is something you are probably already familiar with. But what do they mean? Let's take a look on What is the difference between HTTP and HTTPS?

What is HTTP (HyperText Transfer Protocol)?

  • Hypertext Transfer Protocol (HTTP) is a set of rules that govern information transmission through electronic documents or transfer protocol. This allows World Wide Web browsers and servers to communicate between computing systems, transport information, and make accessing document-embedded resources possible.
  • The Hypertext Transfer Protocol is used for communication across the Internet. It transports and delivers hypertext documents from a server to a client application.
  •  HTTP connects between a client and server to send request packets of information to each other. One of the many purposes of HTTP is to send command requests over the Internet.
  • HTTP is a stateless protocol. These are protocols that don't relate to or depend on previous commands. It's also known as a request-response protocol.

What is HTTPS (HyperText Transfer Protocol Secure)?

  • HTTPS is a secure web protocol. This stands for HyperText Transfer Protocol Secure. As the name suggests, it's a more advanced type of web transfer protocol that's regarded as being more secure than regular HTTP.
  • The HyperText Transfer Protocol Secure uses a port number of 443. This protocol encrypts all communications between the client and web server encrypted with SSL.
  • HTTPS works by establishing two-way data security between the browser and the server.
  • It safeguards your potentially sensitive data from various threats.

What are the significant differences between HTTP and HTTPS?

  • HTTP does not have any advanced security mechanisms. In contrast, HTTPS offers a secure communication channel through SSL or TLS Digital Certificates, which are used to encrypt data flowing between the server and the user's computer.
  • HTTP works on port 80, whereas HTTPS works on port 443 by default.
  • A further difference between HTTPS and HTTP is that the former operates at the Transport Layer of the OSI Model, whereas the latter runs over the Application Layer.
  • When it comes to speed, HTTP stands out as faster than HTTPS because the former saves time by eliminating encryption.

Now let's talk about the advantages and disadvantages of HTTP and HTTPS.

Advantages of HTTP

  • The Hypertext Transfer Protocol works efficiently alongside other protocols on the network.
  • It does not need Runtime support.
  • HTTP locations are directly stored on the computer and thus do not require any encryption to access.
  • It allows cross-platform porting.
  • It can be used over Firewalls.
  • Global applications are possible.

Advantages of HTTPS

  • Generally, all sites that run on HTTPS automatically redirect themselves to HTTPS. So even if people type in HTTP:// at the beginning, they will be redirected to the HTTPS version of your website.
  • It is generally used for transactions involving some security, such as online banking.
  • It uses SSL technology to guard users. Each SSL contains a unique and valid username in the certificate owner.

Since we've seen the advantages of both HTTP and HTTPS, let's look into their limitations.

Disadvantages of HTTP

  • It provides little privacy, and content is visible to everyone.
  • It uses virtually no encryption method, and anyone can change the content of this type of document. In short, it offers very little security.

Disadvantages of HTTPS

  • Despite HTTPS' having the ability to secure a connection, it cannot connect itself to cached pages on one's browser.
  • There is no security to the data in the browser memory.
  • HTTPS is slower.

Difference between HTTP and HTTPS.

Parameters HTTP HTTPS
Protocol It is a hypertext transfer protocol. It is a hypertext transfer protocol with security.
Security It is less secure. Anyone can read and edit content. It is more secure and used for secure transactions like banking, etc.
Port Port 80 is the default port. Port 443 is the default port.
Usage HTTP URLs begin with HTTP:// HTTPS URLs start with https://
Encryption It does not encrypt data while transferring it. The data is encrypted before being transferred and decrypted again at the receiver's end.
Speed It is faster than HTTPS, as no time is consumed in encryption and decryption. It is slower than HTTP, as time is consumed in data encryption and decryption.

How to Convert HTTP to HTTPS

  • The first step is to get an SSL certificate.
  • Secondly, you will have to set the application up for use with the website's hosting account by setting several different settings to ensure the whole thing runs smoothly.
  • In the next step, you must set up 301 redirects. To do this, you will have to alter a file called .htaccess found in the root directory.
  • The last step is updating the robots.txt file, telling search engines about your switch, and performing a sitemap submission to Google Webmaster Tools.

Which one is better when we compare HTTP vs HTTPS?

The answer is clear when it comes to HTTP vs HTTPS.

HTTPS adds an extra layer of protection, including encryption and integrity, to the connection between your server and the end user's browser - which just so happens to include sensitive information in addition to increased SERP ranking.
