The first polyalphabetic was the call encryption encryption Alberti, created by Leon Battista Alberti around 1467. The Vigenère cipher uses this table together with a keyword to encrypt a message. The algorithm is a keyword-based system that uses a series of different Caesar ciphers based on the letters of the keyword. It was first used by Leon Battista Alberti (an artist, linguist, architect, philosopher and more) around 1467. Previously I looked at the Vigenère cipher, but I did not have a working Python example.After some thought and consideration I came to the realisation that the Vigenère cipher is pretty much just a Caesar cipher with a shift that changes each letter, which then allowed me to figure out how to make it in Python.
