A Revolutionary Algorithm Earth-Shattering A cryptographic algorithm that can only be cracked by computational power 1 The History of Cryptography 5th Century BC, the ancient Greeks used a stick called scytale to transmit encrypted messages. To encrypt, a strip of paper was wrapped around the stick, and the message was written horizontally along the stick. … Read more
(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
DES Algorithm •DES stands for Data Encryption Standard, which is a block algorithm that uses a key for encryption. DES Algorithm Input Parameters •The input parameters for the DES algorithm are three: Key, Data, Mode. The Key is 7 bytes or 56 bits long, serving as the working key for the DES algorithm; Data is … Read more

Alan Turing was primarily responsible for breaking the German Enigma cipher system during World War II. Decrypting codes required extensive computation, and Turing understood that to do a good job, one must first sharpen their tools. Thus, a computer called COLOSSUS was developed in 1943, and a total of 10 such electronic computers were produced, … Read more
Today, we will introduce commonly used encryption algorithms, their classifications, and applications. 1. Symmetric Encryption Algorithms Symmetric means that both parties using this encryption method use the same key for encryption and decryption. The key is the instruction that controls the encryption and decryption process. The algorithm is a set of rules that specifies how … Read more
