HTTP vs. HTTPS: What's the Difference?
Edited by Huma Saeed || By Sumera Saeed || Updated on October 23, 2023
HTTP is the standard protocol for transmitting web content, while HTTPS is its secure version, using encryption to protect data.
Key Differences
HTTP, standing for HyperText Transfer Protocol, is a system used to send and receive information on the web. It serves as a request-response protocol in which a client requests information, and a server provides it. However, HTTP has a fundamental drawback: it lacks security. Data transmitted using HTTP is in plain text, making it susceptible to eavesdropping or tampering by malicious entities.

Enter HTTPS, which means HyperText Transfer Protocol Secure. As the name implies, HTTPS is the secure version of HTTP. It employs a layer of security on the data, using encryption protocols such as SSL (Secure Sockets Layer) or TLS (Transport Layer Security). This encryption ensures that the information being transferred between the client and server remains confidential and intact.

One of the critical distinctions between HTTP and HTTPS lies in their URLs. Websites that utilize HTTPS will have their URLs starting with "https://", while those using HTTP begin with "http://". This differentiation is crucial as it instantly informs users if their connection to the website is secure or not.

Another notable difference between HTTP and HTTPS is the presence of certificates. For a website to use HTTPS, it must obtain a certificate from a Certificate Authority (CA). This certificate verifies the website's legitimacy, ensuring users that the site they're visiting is genuine and not a malicious imitation. In contrast, HTTP does not have such verification mechanisms.

In essence, while both HTTP and HTTPS are protocols to transfer web content, HTTPS offers an additional layer of security, ensuring data confidentiality, integrity, and verification through certificates.
