1. Http HyperText Transfer Protocol, is the most widely used protocol on the Internet, a standard that all WWW files must follow. The data transmitted using the HTTP protocol is unencrypted, which means it is in plaintext, making it very insecure to transmit private information using the HTTP protocol. Uses TCP port: 80 2. Https … Read more
1. Basic Concepts HTTP: is the most widely used network protocol on the Internet, serving as a standard for requests and responses between clients and servers. It is a protocol used to transfer hypertext from WWW servers to local browsers, making browsing more efficient and reducing network transmission. HTTPS: is a secure version of HTTP, … Read more
To clearly explain the implementation principles of the HTTPS protocol, we need to understand at least the following background knowledge. 1. A rough understanding of several basic terms (HTTPS, SSL, TLS) 2. A rough understanding of the relationship between HTTP and TCP (especially “short connection” vs. “long connection”) 3. A rough understanding of the concept … Read more
1. Why Use HTTPS Instead of HTTP 1.1 Differences Between HTTPS and HTTP 1) The HTTPS protocol requires a certificate application from a CA, and generally, free certificates are rare and often require payment. 2) HTTP is the Hypertext Transfer Protocol, where information is transmitted in plain text, while HTTPS is a secure SSL encrypted … Read more
Before discussing HTTPS, let’s first talk about what HTTP is. HTTP is a protocol that we use when browsing the web. The data transmitted using the HTTP protocol is unencrypted, meaning it is in plain text, making it very insecure to transmit private information using HTTP. To ensure that this private data can be transmitted … Read more
Are you tired of bulky HTTP server libraries struggling on resource-constrained embedded Linux systems? Do you crave a lightweight, high-performance, and easily extensible HTTP server solution? Then, allow me to introduce—libuhttpd! What is libuhttpd? libuhttpd is a super lightweight, high-performance HTTP server library based on libev and http-parser, specifically designed for embedded Linux systems. It … Read more
HTTP (Hypertext Transfer Protocol) and HTTPS (Secure Hypertext Transfer Protocol) are protocols used for transmitting data over the internet. The main difference between them lies in security and data encryption. Below is a detailed comparison and introduction to the relevant mechanisms: 1. Differences Between HTTP and HTTPS Security: HTTP: Data is transmitted in plaintext, making … Read more

Good evening, my friends! When we browse the internet, we often see “http” or “https” at the beginning of a URL. Both represent the HyperText Transfer Protocol, but there is a key difference between them: “security.” Today, we will explore the differences between HTTPS and HTTP, as well as their working principles and applications. Today’s … Read more
National encryption refers to the domestic encryption algorithms recognized by the National Cryptography Administration. The main algorithms include SM1, SM2, SM3, SM4, and the latest SM9. These algorithms are primarily used in domestic environments as recognized by the National Cryptography Administration. SM2 Algorithm: The SM2 elliptic curve public key cryptography algorithm is a public key … Read more
