The task of this exercise is to find out which type of encryption was used for encrypting messages. The possible types are: Shift cipher (e.g., Caesar's Cipher), Substitution Cipher, and Vigenere. For each pair of plaintext and ciphertext, find out which method of encryption was used and write down the key that was used for this method.

What will we do? Below are a few cryptographic tasks to make sure you're familiar with various methods of cryptography - from simple ciphers to RSA! 1) Caesar's Cipher Roses are Red, Violets are Blue. Caesar would be 8, is your first clue. Decrypt "ozcjmz" and enter it below. 2) Create your own Cryptography using a Substitution Cipher. Include your SHORT plaintext, the substitution key, along with the ciphertext! Please provide Excel or source code if you decide to implement this in a programming language or Excel.
