The Affine cipher operates on the mathematical formula: The key feature of the affine cipher is that it uses a simple mathematical function to perform the substitution. The Affine cipher is a type of monoalphabetic substitution cipher, which means that it is a method of encrypting plaintext by replacing each letter with another letter. However, the Affine Cipher, as a more advanced monoalphabetic substitution cipher, gained prominence through contributions from Arabic scholars during the Islamic Golden Age. The fundamental concept of shifting letters, akin to the Caesar Cipher, traces back to Julius Caesar in ancient Rome. The history of the Affine Cipher is deeply rooted in the ancient world, finding its earliest applications in classical cryptography. In this tutorial, we’re paying a special visit to classical cryptography - We will see how to implement the Affine cipher and use it to encrypt our plaintexts or messages. Confused by complex code?
