The Basics of HTTP

Hypertext Transfer Protocol (HTTP) is the fundamental communication protocol used for transferring data over the internet. It defines how devices communicate with each other to display web pages and send requests to servers. The standard HTTP version 1.1 uses a three-way handshaking process between a client (e.g., web browser) and a server, establishing connections, sending and receiving data, and handling errors.

The Addition of Secure Sockets Layer (SSL) in HTTPS

However, the standard HTTP protocol is not secure against interception and eavesdropping. To address this issue, the Hypertext Transfer Protocol Secure (HTTPS) was developed. Secure sockets layer (SSL), an extension of the TLS (Transport Layer Security) protocol, provides encryption and authentication for web communications over the internet. By including an SSL certificate in the HTTPS connection establishment process, HTTPS ensures that data remains confidential and tamper-proof.

Key Differences

In summary, the key differences between HTTP and HTTPS are: - Secure Sockets Layer (SSL) encryption - Authentication through certificates - Increased security for web communications
