(For algorithm enthusiasts, star it to hone your programming skills) Source: labuladong The “password” discussed here is not the same concept as the passwords we use daily. This article discusses the encryption algorithms that primarily address the problems of encryption and decryption in information transmission. It is assumed that the data transmission process is insecure, … Read more
This article only describes the use of the AES algorithm without going into too much detail about its principles. Readers who want to understand its principles can search online. 1. Introduction to AES The Advanced Encryption Standard (AES) is the most common symmetric encryption algorithm. A symmetric encryption algorithm uses the same key for both … Read more
An encryption algorithm that can only be cracked by computing power 1 The History of Human Encryption In the 5th century BC, the ancient Greeks used a stick called scytale to transmit encrypted messages. To encrypt, one would wrap a strip of paper around the stick and write the message horizontally along the stick, rotating … Read more
This article compares the performance of four commonly used encryption algorithms: DES, 3DES, Blowfish, and AES (Rijndael). By running several encryption settings to process data blocks of different sizes, the encryption/decryption speed of the algorithms is evaluated and compared. The simulation is performed using C#. Keywords: encryption algorithms, performance, analysis, AES, DES, Blowfish, TripleDES, cryptography … Read more
Introduction This article attempts to discuss the evolution of cryptographic algorithms from ancient to modern times, as well as the key cryptographic algorithms that have emerged throughout this process. Due to my limited knowledge, I hope for your guidance if there are any errors. About Cryptographic Algorithms At first glance, cryptographic algorithms may seem distant … Read more
Encryption is the process of converting plaintext into ciphertext using algorithms to prevent unauthorized access. Encryption is divided into two types: 1. Symmetric Key Encryption 2. Asymmetric Encryption (Public Key Encryption) How Encryption Algorithms Work An encryption algorithm is a mathematical function that converts plaintext into ciphertext, typically using a key to perform encryption and … Read more
Today’s Technology News Recently, data from the analysis company Statcounter shows that Android has surpassed Windows for the first time to become the largest operating system. It is important to emphasize that Statcounter examines data related to web usage, not installation numbers. Among the websites tracked by StatCounter, Android users account for 37.93% of visits, … Read more
