HTTP vs. HTTPS: What’s the Difference?

Difference between HTTPS and HTTP is an additional security that a website gets once an SSL certificate is installed. HTTPS creates a secure connection while HTTP is non-secure version.

Online privacy is key for website owners. It does not only help them safeguard users’ personal details but also maintain their trust. In the absence of such control, unscrupulous characters might exploit your identity for their own gain.

As people become more interconnected, their online activities surge. From shopping to socializing, countless interactions occur on various devices.

Yet, individuals willingly disclose data on platforms like Facebook, Snapchat, Meta’s Threads and Twitter. However, regarding private matters like health, wealth, and family, a guarded stance prevails.

In the digital space, HTTPS (Hypertext Transfer Protocol Secure) plays a key role. It safeguards data during online exchanges; ensuring hackers can’t intercept sensitive info.

A recent study indicates that over 95% of traffic across Google is encrypted, enhancing online privacy and user protection.

What is HTTPS?

HTTPS, which stands for Hypertext Transfer Protocol Secure, is a key technology for safeguarding online interactions. Imagine it as a secure tunnel that shields your data as it journeys between your device and a website’s server.

This is especially important when sharing sensitive information like passwords or credit card details. HTTPS operates like a digital safeguard, encrypting the data you send and receive.

This encryption converts your information into a complex code that can only be deciphered by the intended recipient – the website’s server.

It ensures that even if a cybercriminal tries to intercept your data, they’ll only get an indecipherable mess.

This protocol has become a standard for websites, symbolized by the padlock icon in the address bar. It not only keeps your personal information safe but also boosts trust.

How HTTPS Works

As already mentioned, HTTPS, or Hypertext Transfer Protocol Secure, acts as a digital safeguard, shielding your online information from prying eyes. It functions like a protective shield during your digital interactions.

Think of it like sending a secret message to an associate. Before your message leaves your hands, it’s placed inside a secure box.

This box can only be unlocked by your associate using a special key. The same applies when you visit a website using HTTPS.

Your data, like passwords or credit card details, is locked in a virtual secure box. And, this process involves two main players; your web browser and the website’s server.

They engage in a secure handshake. It is through this handshake that they exchange cryptographic keys to create a secret code that only they can understand.

This ensures that any data you share is encrypted. It doesn’t matter whether you’re filling out a form or making a purchase. All the data shared is transformed into a jumble of characters. It is only the recipient that can decipher these characters.

Advantages of HTTPS

HTTPS is designed to keep you and your users’ data under lock and key to thwart the bad guys, and make sure your website is trustworthy. It even pleases Google. Here are six advantages of HTTPS for your website;

Advantages of HTTPS

  1. Data Encryption

    HTTPS acts like a secret code for your website’s visitors. When people send or receive information on your site, HTTPS locks up that data.

    This ensures that the data can’t be easily read by outsiders. It’s like putting your info in a safe box that only you and the person you’re talking to can unlock.

    This makes sure sensitive stuff, like credit card numbers or login details remain private. They’re kept safe from hackers trying to eavesdrop on the conversation.

  2. Security Shield

    Just like a security guard watches over your home, HTTPS stands guard over your website. It creates a barrier between potential attackers and your visitors’ data.

    Hackers won’t be able to easily grab personal info, like passwords, which keeps your users safe and helps you build trust. Nobody wants to visit a site that might leak their private information!

  3. Trustworthy Websites

    Imagine if you’re shopping and you see a store with a big padlock on the door – you’d feel safer, right? That padlock means the store is secure.

    That’s the same principle with HTTPS. When your website uses HTTPS, it gets a padlock icon in the browser’s address bar. This signals to your visitors that your website is reliable. It also shows that you have taken extra steps to keep their data secure.

    It’s like assuring them that you care about their privacy and willing to go the extra mile to ensure their privacy and safety when they’re on your site.

  4. Google’s Approval

    Did you know that Google prefers websites that use HTTPS? When your site uses HTTPS, Google sees it as a sign that you care about your visitors’ safety.

    This can boost your website’s ranking in Google’s search results. With a boosted ranking, it means that more people can find your site easily. Think of it as a thumbs-up from Google.

  5. Privacy Power

    When people use your site, their interactions are hidden from snooping eyes. This is especially important for websites dealing with sensitive info, like personal profiles or medical records. HTTPS ensures that what happens on your website stays between you and your visitors.

  6. Mobile Friendly

    Nowadays, many people surf the web on their phones or tablets. The good news is that HTTPS works with these devices too. It ensures that even when your visitors are on the move or using apps to access your site, their data remains secure. This flexibility helps you cater to a wide range of visitors without compromising their safety.

What is HTTP?

HTTP, or Hypertext Transfer Protocol, is the backbone of the World Wide Web. Acting like a conductor, HTTP enforces the rules for sharing information online.

It’s like a language both web browsers and servers understand, ensuring smooth communication. Built on TCP, HTTP arranges and delivers information using structured text, forming connections between text nodes. It’s “stateless,” treating each command independently, without memory of past actions.

How HTTP Works

HTTP is the backbone of web communication. It facilitates data exchange between the client devices and servers.

Clients, often web browsers, send requests for resources like images and text by specifying URLs. Servers receive these requests, locate the resources, and package them into responses.

Requests and responses consist of sub-documents. These may include chunks of data like images and text layouts. These components, once received, assemble into complete web pages to enable a seamless web content delivery.

Web servers host not just content, but also HTTP daemons – programs that wait for and manage incoming requests. Web browsers, acting as clients, construct HTTP requests based on user actions, and then send them to designated IP addresses. Servers’ HTTP daemons process these requests and transmit the corresponding files back to the clients.

Advantages of HTTP

HTTP boasts a string of distinct advantages that elevate its significance in online communication. Here are the five key advantages;

Advantages of HTTP

  1. Platform Independence

    HTTP’s efficiency lies in its cross-platform prowess. It facilitates the seamless movement of data across diverse devices and operating systems. This universal compatibility is the cornerstone for the dynamic cross-platform exchange of resources.

  2. Protocol Integration

    HTTP exhibits a remarkable flexibility to coexist with other protocols, either within the expansive landscape of the Internet or across various networks. Its adaptable nature makes it a versatile collaborator, contributing to the intricate web of online interactions.

  3. Minimal Network Overhead

    The absence of a connection-oriented framework in HTTP translates into leaner network overhead. Without the burden of creating and maintaining session states, the protocol expedites data transfer. This streamlined approach is a boon for swift and efficient communication.

  4. Caching Efficiency

    HTTP’s architecture lends itself to rapid accessibility. Pages are cached on local computers and internet caches, enabling speedy retrieval of frequently visited resources. This caching mechanism ensures that information is readily available, enhancing user experience and reducing latency.

  5. Firewall Friendliness

    HTTP surmounts the barriers imposed by firewalls, paving the way for global applications. Its adeptness at traversing firewalls ensures that information can flow freely, without being limited by geographical boundaries.

Limitations of HTTP

While HTTP stands as a pillar of web communication, its strengths are met with certain limitations that warrant consideration. Here are three notable limitations of HTTP;

Data Integrity Vulnerability

HTTP, in its standard form, lacks built-in mechanisms to ensure the integrity of transmitted data. This omission opens the door to potential tampering during data transfer, leaving information susceptible to unauthorized modifications.

Privacy Concerns

The absence of encryption in traditional HTTP exposes user data to prying eyes during transmission. Sensitive information, such as login credentials or personal details, can be intercepted by malicious actors.

Statelessness

HTTP’s statelessness, while reducing network overhead, poses challenges for certain types of applications. Complex tasks requiring the retention of user session states demand additional efforts to manage and synchronize data across requests. This can lead to intricate programming solutions and potentially impact user experience.

Differences between HTTP and HTTPS

The main difference between HTTP and HTTPS is security, HTTPS is secured protocol while HTTP is not.

Both protocols facilitate data exchange between clients and servers. However, they diverge significantly in terms of security, vulnerability, and overall performance.

Here are the key differences between HTTP and HTTPS;

Aspect HTTP HTTPS

URL Starts with The URL starts with “http://”. The URL starts with “https://”.
Data Encryption Data transmission is unencrypted. Encrypts data to prevent interception.
Used for Suitable for standard content delivery. Essential for securing sensitive data, transactions, and logins.
Domain Name Validation No validation required for the domain. Requires domain validation through SSL certificates.
Protocol (TCP/IP) Utilizes TCP (Transmission Control Protocol). Doesn’t have any separate protocol. Relies on HTTP but uses encrypted TLS/SSL connections.

How HTTP & HTTPS Sites Display in Your Browser (Chrome, Firefox, and Microsoft Edge)

When you open a website in your browser—like Chrome, Firefox, or Microsoft Edge—the type of connection it uses affects how it displays.

  1. HTTP Sites: When you visit a regular HTTP site, your browser talks to the site without extra protection. Information travels back and forth openly. The website’s address begins with “http://” in the browser’s bar.
  2. HTTPS Sites: HTTPS is more secure. Your browser and the website have a secret way of talking, making sure no one snoops. The site’s address begins with “https://” and usually has a little padlock icon.

Chrome

In Chrome, a regular HTTP site shows a label “Not Secure” before the site’s address. See the image below;

Chrome Not Secure

For HTTPS, you’ll see a padlock icon and “https”. See image below;
