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
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

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
