The Differences Between HTTP and HTTPS

HTTP (Hypertext Transfer Protocol) is the standard protocol used for transferring data over the internet, while HTTPS (Secure Hypertext Transfer Protocol) is a more secure alternative. In this article, we will explore the differences between these two protocols.

What is HTTP?

HTTP is a transport-layer protocol that enables communication between web servers and clients over the internet. It uses plain text to transmit data, which makes it vulnerable to interception and eavesdropping by malicious actors.

What is HTTPS?

HTTPS is an extension of HTTP that adds encryption to the protocol, making it more secure for transferring sensitive information such as credit card numbers, passwords, and personal data. It uses Transport Layer Security (TLS) or Secure Sockets Layer (SSL) protocols to encrypt data in transit.

Differences Between HTTP and HTTPS

The main difference between HTTP and HTTPS is the use of encryption. While HTTP uses plain text, HTTPS uses TLS/SSL protocols to encrypt data. This makes HTTPS more secure for transferring sensitive information.

Additionally, HTTPS requires a valid SSL/TLS certificate, which is issued by a trusted Certificate Authority (CA). This ensures that the website being accessed has not been compromised or tampered with.

When to Use HTTP and When to Use HTTPS

HTTP is suitable for general web browsing and transferring small amounts of data. However, it's recommended to use HTTPS for sensitive activities such as online banking, shopping, and accessing personal data.
