What Is HTTPS?

Security is a paramount concern in the interconnected world of today. One key player in this digital security landscape is HTTPS.  In this document, we’ll discuss HTTPS and its importance in maintaining the security of our online communications. We also explored how it works and the benefits it offers.

This protocol, integral to the functioning of the internet, ensures that the data exchanged between your browser and the website you are visiting is secure and cannot be intercepted by any unwanted third parties.

What is HTTPS?

Hypertext Transfer Protocol Secure, commonly known as HTTPS, refers to an internet communication protocol that protects data integrity and confidentiality during the exchange of data between a user’s computer and a website. The use of encryption in HTTPS ensures that any data transferred remains private and integral, providing a secure pipeline for data to travel.

How does HTTPS work?

Understanding the workings of HTTPS involves delving a bit into the technical side. The magic behind the security provided by HTTPS is an encryption protocol called SSL/TLS (Secure Sockets Layer/Transport Layer Security). This protocol uses a system of public and private keys to encrypt data.

In the process of establishing a secure connection with a website, the browser requests the site’s SSL certificate. This certificate, issued by a trusted Certificate Authority, serves as proof of the website’s identity. Upon validation of the certificate as trustworthy, the creation of a unique session key occurs. Encryption of this key with the website’s public key follows, leading to its transfer back to the website. The server then decrypts it using its private key, confirming the establishment of a secure connection.


The key difference between HTTP and HTTPS is the ‘S’ at the end, which stands for ‘secure’. While HTTP transfers data in plain text, which can be easily intercepted and read by hackers, HTTPS encrypts the data, making it look like gibberish to anyone who intercepts it without the correct decryption key.

Using HTTPS is like sending a coded message where only the sender and the receiver know the code, protecting sensitive data from unauthorized access and hacking attempts.

Reasons to Use HTTPS

  1. Increased Security: HTTPS significantly enhances the security of user data by encrypting the information transmitted between the website and the user’s browser. This encryption makes it incredibly difficult for cybercriminals to decipher, thus safeguarding data from unauthorized access and potential misuse.
  2. Trustworthiness: Websites that use HTTPS are often seen as more trustworthy by users. This is because browsers label HTTPS sites as ‘secure’, providing an immediate visual cue to users that their data will be protected when interacting with the site.
  3. Authentication: HTTPS provides a mechanism of authentication, ensuring that the website the user is interacting with is indeed the one it claims to be. This not only helps protect users from falling victim to phishing or spoofing attacks but also inspires confidence in the website’s legitimacy.
  4. Improvement in Ranking: As search engines prioritize secure websites, using HTTPS can potentially boost a website’s ranking in search engine results pages (SERPs). This can lead to increased website visibility, traffic, and conversions.
  5. Compliance: Many regulatory bodies and industry standards require the use of HTTPS to ensure the security of data being transmitted over the internet. This includes credit card information, personal information, and other sensitive data.

The importance of adopting HTTPS

HTTPS is an essential aspect of internet communication, providing a secure pathway for data transfer between the client and the server. With its robust encryption techniques, it safeguards sensitive data, protects against unauthorized access, and helps prevent hacking attempts. In our journey of embracing digital transformation, the significance of employing HTTPS cannot be emphasized enough. So, whether you’re an IT professional or a casual internet user, always look for the ‘s’ in HTTPS before sharing any sensitive data online.
