WebLearn about the basics of cryptography. A mixture of maths/computer studies and history in one lesson. Julius Caesar used coded messages to his generals, Morse code was used in World War 1 and 2.... WebWorksheet 1: The Caesar Cipher . Julius Caesar used a simple substitution cipher to send messages to his troops. He substituted each letter by the letter that was 3 places further along in the alphabet, so that “a” was replaced with “D”, WebOn this course, you will learn about what encryption is and understand its use in the past by using the Caesar and Vigenère ciphers. You will also look at the present and future of encryption and investigate both symmetric and asymmetric encryption schemes. birds of paradise tattoo images
