What is HTTPS?

HTTPS or Hypertext Transfer Protocol Secure is the secure extension of the HTTP protocol. It is used for secure encrypted communication between web browsers and web servers.

HTTPS stands for Hyper Text Transfer Protocol Secure and it's the secure encrypted version of the basic HTTP protocol that is used when communicating on the internet

What is HTTPS?

HTTPS stands for Hypertext Transfer Protocol Secure that keeps sensitive data private when transferred between users and websites, with encryption technology ensuring only authorized parties can view it.

HTTPS is a way to securely and privately transmit data between two parties. It is also the most common name for HTTP Secure, which encrypts all of your communications so that they can't be intercepted or read by third parties. HTTPS Everywhere helps you connect to websites through the encrypted version of HTTP (HTTPS) whenever possible. The web users will find a web page reliable with HTTPS.

What is HTTPS?

If you've ever wondered what HTTPS is, don't worry–you're not alone. The Internet can be an intimidating place to navigate for the uninitiated. You must learn about this protocol before deciding which websites to sign up for if you're just starting. Luckily, we're here to help modern web browsers.

There are many different URLs that you can use to access a website. One type is called an HTTP URL, which stands for Hypertext Transfer Protocol. This protocol specifies how data will be exchanged over the Internet.

There's also FTP (File Transfer Protocol), Telnet, and more! But one of the most popular protocols is HTTPS, which stands for Hypertext Transport Layer Security.

It has become so popular because it encrypts all information sent between your browser and the server hosting your site – this includes passwords as well as credit card numbers!

Difference between HTTP and HTTPS

http vs https

HTTP and HTTPS are two of the most common web protocols that you will use. However, there is a big difference between the two! HTTP stands for Hypertext Transfer Protocol and transfers data from one device to another over the Internet. It's considered “insecure” because it sends information in plain text – meaning anyone can intercept your data as it travels through cyberspace.

On the other hand, HTTPS (Hypertext Transfer Protocol Secure) is a more secure version of HTTP because all communication happens with encryption and authentication – this means that those pesky hackers won't be able to see what you're up to on your next online shopping spree!

HTTP is independent of the operating system and works on top of TCP/IP. HTTP uses port 80 by default, but any port can be used. A good analogy here would be like your house address (home). You may have a different house number depending on the street, apartment number, city you live in, etc. But it's still your house; it's all about where you are located. This is how HTTP works as well.

It's HTTP with an added SSL/TLS layer of security so that all data transferred from client to server is encrypted and protected within a secure connection. HTTPS uses TCP port 443 by default, but any port can also be used. HTTPS secures the communication between a client and a server using encryption schemes such as SSL. HTTPS provides authentication of the website via digital certificates.

It also ensures the integrity of communications by utilizing message authentication codes (MACs). So not only does it protect information during transfers via encrypted channels, but it also protects the information from being changed along the way! An analogy here would be like your front door key. You have a key to get into your house, protecting you from outsiders, burglars, etc. This is how HTTPS works as well. With HTTP protocol, the web pages and web browsers include a secure sockets layer for better efficiency.

Can HTTPS be hacked?

At the 31st Chaos Communication Congress, security researcher Moxie Marlinspike presented HTTPS BE hacking. This is an attack against SSL/TLS. It does not exploit a vulnerability in any protocols but uses clever social engineering to trick victims into checking fake certificates.

The possibility of such attacks has been discussed before. Still, this time a successful proof-of-concept implementation is explained, including client and server source code that you can run yourself.

During his talk, Marlinspike explains how HTTPS works, why it sometimes fails, and how one might attack it. In addition, he presents a novel technique for performing secure DNS lookups and bypassing passive eavesdropping techniques like those used by censorship systems, corporate firewalls, and even governmental intercept systems.

More about the details

The talk covers a whole range of HTTPS woes and demonstrates how, in some cases, it may be possible to accomplish a full SSL/TLS exchange without ever possessing the expected server certificate. While the attack targets HTTPS websites, there's no reason why similar techniques can't be used against other protocols built on top of SSL/TLS.

Marlinspike has published an [IPREDATOR client](<https://github.com/iPredator/>) designed to thwart such attacks by allowing such attacks users to establish secure connections with each other using self-signed certificates.

He discusses the design goals behind I predator and presents several optimizations he introduced to run faster than most widely available alternative anonymous communication tools.

What does HTTPS provide?

Here is what this internet service provider comes with:

Encryption

No one can see your data, not even the WiFi operator. This means that **ISP** does not know which websites or other services you use and **cannot block them or discriminate between them**. Also, it is much harder to build a profile of your behavior over time by comparing different sessions because they are fully encrypted separately.  

Authentication

When browsing to https://wwwoyoyo.com, this is checked using certificates by your browser, which is sure that he talks to myoyoyo.com. The only way for the website to get such a certificate is to prove that they are myoyoyo.com. We call this authentication.

HTTPS *is not* just encryption, it provides **authentication** too! Without HTTPS, **your ISP can see which www. links you open and the content of their unencrypted communications** (they can still guess that you talked with email or Facebook by looking at your DNS traffic, but that's it)

Is HTTPS Safe to use?

If you use HTTPS for exchanging sensitive information, you mustn't have certificate verification errors. In other words, the remote endpoint needs to be trustworthy and also needs to have a valid SSL certificate that verifies as trusted by one of the root CAs in the trust store used by your client device.  

This is a lot harder than just installing a self-signed cert on your server and configuring your web server software correctly; yet, many developers think this will suffice for their application.

Another problem is strict transport security (HSTS). Enabling this in your application is only truly secure when you add support for certificate pinning.

And adding such a vital security feature like pinning is hard and costly in manpower and is considered overkill unless your application deals with extremely sensitive data (e.g., financial or medical information).

Google Search VS Bing Search

A post on Imgur shows how both Google and Bing give different results when searching for the “TTPS” site: Imgur vs. StackOverflow. When you search offline, Google will show you the HTTPS version of a website if available. On the other hand, Bing always redirects HTTPS to the HTTP version.

 It is still unclear how Comodo Antivirus detects malware hidden inside an HTTPS connection when there is no way for anyone to access encrypted data in between due to the nature of the HTTPS protocol itself.

However, this strange case reminds us that machine learning can be used not only to identify malicious files but also to automatically remove them from your computer without human intervention.

Many antivirus companies use machine learning in different ways, and they claim that their products can protect you better than any other solutions out there!

Conclusion

The Internet is an unsafe place. Hackers are always looking for opportunities to break into your site and steal your information. HTTPS is the best way to prevent this from happening! It offers Transport Layer Security TLS within the HTTPS pages and web servers.
