Scratch Advanced – Week 3 – Cryptography

Hope everyone enjoyed last week.

This week we began a series of sessions on Cryptography. We began by demonstrating why we might use Cryptography. What is Cyrptography

What created a Scratch project to Encrypt a single word or sentence using a Reverse Cipher. Notes for this Scratch project are at: Scratch Project Notes (Reverse Cipher)

We then improved the Scratch project to Decrypt the same word or sentence back to its original form.

We discussed the limitations of a Reverse Cipher and began the introduction of the next session where we will be creating a Scratch program to Encrypt and Decrypt a word or sentence using one of the most famous ciphers the “Caesar Cipher”. Named after the Roman figure Julius Caesar.
