In our daily lives, we often encounter various encryption algorithms. Today, let’s discuss the Python implementations of these encryption algorithms. Most commonly used encryption methods have corresponding Python libraries, so we generally no longer need to implement specific algorithms with code. MD5 Encryption Full name: MD5 Message-Digest Algorithm, a widely used cryptographic hash function that … Read more
Bouncy Castle: The Versatile Encryption Library Hello everyone! Today I want to share with you a very powerful encryption library in both Java and C# – Bouncy Castle. As a cryptography enthusiast, I particularly love this library because it is like a treasure chest that contains almost all commonly used encryption algorithms. Whether it’s simple … Read more
Source: https://www.biaodianfu.com/aes.html The Data Encryption Standard (DES) has a key length of 56 bits, resulting in a theoretical security strength of 256. However, the late 20th century was a period of rapid development in computing, and advancements in component manufacturing technology led to increasing computational power, making DES insufficiently secure. On January 2, 1997, the … Read more
Encryption Algorithms: Data Security Assurance for Microcontrollers and PLCs In industrial automation systems, data security is a critical issue that cannot be ignored. Whether it is a microcontroller or a programmable logic controller (PLC), they often need to handle and transmit important data such as production parameters, quality records, and machine status. If this data … Read more
JCL: The Alchemist of Java Encryption Algorithms! Hello, friends! Today, Niu Ge will talk to you about the popular topic of Java encryption algorithms. Do you remember how confused I was the first time I encountered encryption algorithms when I transitioned from testing to Java? It was like stepping into the kitchen for the first … Read more
There are two sayings: 1) Algorithms and data structures are an important part of programming. If you lose algorithms and data structures, you lose everything. 2) Programming is algorithms and data structures; algorithms and data structures are the soul of programming. Note that this is not my own statement, but a summary from countless programmers. … Read more
Source: Aisen Smart, Thinking Author: IoT Media Edited and Published The LoRa industry has experienced significant ups and downs in the past year. At the end of last year, a policy from the Ministry of Industry and Information Technology stirred controversy within the industry and cast a shadow over the development of the LoRa industry. … Read more
0 Introduction With the help of ECC (Elliptic Curve Cryptography), we can utilize the powerful capabilities of public key encryption while achieving the speed and security of symmetric encryption. Therefore, we gradually turn to practical scenarios, focusing on the following categories: (1). Public Key Key Exchange Protocols: ECDH (P256), ECDH (P384), ECDH (P521), X25519 and … Read more
