Скачать или смотреть Beyond Binary: Intro to Computer Science | Arrays, Encryption, and more on Binary | Ep 2

Let's learn computer science in the most fun and glamorous way possible: all dragged up! In this lesson, we learn about encryption and how to manipulate text and images to store secrets in them. We'll cover how to read binary, ASCII, Caesar ciphers, Strings and introduce the Array all in the most popular programming language.

Warmup: Try updating the toUppercase function to be toLowercase

Caesar cipher encrypter and decrypter
prompt user for an input
rotate all the letters by a number of your choice
wrap around the end letters to the beginning using the % operator (more information on that here: https://www.w3schools.com/js/js_arith...)
for the decrypter ask for an offset number and a message then reverse and print the encryption

Decrypting images
Use this as a starting point: https://codepen.io/theAnnaLytical/pen...
take the loaded in images
remove the green and blue pixels (set to 0)
increase the intensity of the red pixels
