What is Https? Why is it important?

With the introduction of the internet and the digital world into our lives, we are learning different and new things every day. In this article, we will answer your questions about the concepts of “HTTP” or “HTTPS“, a term that almost all of us often see on the Internet.

Http stands for Hyper Text Transfer Protocol and Https as Hyper Text Transfer Protocol Secure.

What is Https?

HTTPS stands for Hypertext Transfer Protocol Secure. It is a protocol for secure communication over the internet that provides encryption and authentication between a website and a user’s browser. When you connect to a website using HTTPS, your browser and the website’s server establish a secure connection that encrypts all the data transmitted between them. This helps protect sensitive information, such as login credentials, credit card details, and other personal information, from interception by third parties. The use of HTTPS is indicated by a padlock icon in the browser’s address bar and the “https://” prefix in the URL.

What is the difference between Http and Https?

The main difference between HTTP and HTTPS is that HTTPS is a more secure version of HTTP. HTTP (Hypertext Transfer Protocol) is a protocol that is used to transfer data over the internet, while HTTPS (Hypertext Transfer Protocol Secure) is a more secure version of HTTP that uses SSL/TLS encryption to protect data as it is transmitted over the internet.

When you connect to a website using HTTPS, your browser and the website’s server establish a secure connection that encrypts all the data transmitted between them. This helps protect sensitive information, such as login credentials, credit card details, and other personal information, from interception by third parties.

In contrast, HTTP does not provide any encryption or security features, which means that data transmitted over HTTP can be intercepted and read by anyone who has access to the network. Because of this, it is recommended to use HTTPS for any website that collects sensitive data or requires authentication.

How does HTTPS work?

HTTPS (Hypertext Transfer Protocol Secure) works by using SSL/TLS encryption to secure the connection between a user’s browser and a website’s server. Here’s how it works:

A user connects to a website using HTTPS by typing “https://” in the browser’s address bar, or by clicking a link that uses the HTTPS protocol.

The website’s server responds by sending a digital certificate to the user’s browser. This certificate contains the website’s public key and other information that is used to verify the website’s identity.

The user’s browser verifies the website’s identity by checking the digital certificate against a list of trusted certificate authorities (CAs). If the certificate is valid and the website’s identity is confirmed, the browser proceeds to establish a secure connection with the website’s server.

The browser and the website’s server negotiate a session key, which is used to encrypt all data transmitted between them. This session key is unique to the current session and is discarded after the connection is closed.

Once the secure connection is established, all data transmitted between the browser and the website’s server is encrypted and cannot be intercepted or read by third parties.

In summary, HTTPS uses encryption to protect the privacy and security of data transmitted over the internet, and it provides authentication to ensure that users are communicating with the intended website.

What information does HTTPS provide users about website owners?

HTTPS (Hypertext Transfer Protocol Secure) provides users with information about website owners through a digital certificate that is issued to the website by a trusted certificate authority (CA). This certificate contains information about the website owner, including the website’s domain name, the owner’s name and address, and the expiration date of the certificate.

When a user connects to a website using HTTPS, their browser checks the digital certificate to confirm that the website is owned by a legitimate entity and that the website’s identity has been verified by a trusted CA. If the certificate is valid and the website’s identity is confirmed, the browser displays a padlock icon in the address bar, indicating that the website is secure.

In addition to the padlock icon, some browsers may also display additional information about the website owner, such as the company name, location, and other relevant details. This information can help users make informed decisions about whether to trust a website and whether to share sensitive information with it.

Misconceptions About Https

There are a few common misconceptions about HTTPS (Hypertext Transfer Protocol Secure) that are worth noting:

• HTTPS is only necessary for e-commerce sites: While it’s true that e-commerce sites and other websites that handle sensitive information should use HTTPS, it’s also important for all websites to use HTTPS. HTTPS provides privacy and security for all data transmitted over the internet, not just credit card information and other sensitive data.
• Slows down website performance: While HTTPS does add some overhead to website performance, modern encryption protocols and hardware acceleration make it possible to use HTTPS without a significant impact on website speed.
• It is difficult to implement: While implementing HTTPS does require some technical expertise, it’s become much easier in recent years with the availability of free SSL/TLS certificates and tools to automate the process.
• Guarantees that a website is safe: While HTTPS does provide privacy and security for data transmitted over the internet, it does not guarantee that a website is safe or free from malware or other security threats. Users should still exercise caution and use other security measures, such as antivirus software and safe browsing practices.
  

Overall

In today’s world, online privacy and security are of utmost importance. HTTPS (Hypertext Transfer Protocol Secure) is a crucial tool for protecting sensitive information and maintaining privacy and security on the internet. By encrypting all data transmitted between a user’s browser and a website’s server, HTTPS ensures that information such as login credentials, credit card details, and other personal information is protected from interception and reading by third parties. With the rise of cyberattacks and online security threats, it is more important than ever to use HTTPS on all websites that collect sensitive data or require authentication.
