The Building Blocks of Encryption: Classical Techniques Explained

Before the age of digital communication, when computing power was measured in human intellect and secrecy was maintained through ingenuity rather than machine algorithms, the foundation of secure communication rested on classical encryption techniques. Classical encryption refers to the methods of transforming readable messages, or plaintext, into unreadable sequences known as ciphertext using systematic rules.… Read More »
