Today. We learned some encryption. Yeah 🙂
The encryption for today is simple substitution 😉
The kids had to type down everything to find out what “encryption” means. Kids won’t listen if you explain things on the whiteboard. You just have to make them do things and let them see what happen 😀
Once they finished they still need to debug some errors.
Because this code only work with Python 2.7
And supposed to execute on the command prompt because it takes arguments
So we had to modified it like this to make it work for today. Next time we will use tkinter to make a simple GUI for this 😉
After the kids understood how the encryption works (by shifting the alphabet k steps to the right), they found their own way to find out how to do decryption; by shifting k steps to the left! YEAAAH 😀
And at the end of the class, these two girls were given a task to give their classmates a case to be solved. A ciphertext to be decrypted 😀
And this is. What they came up with LOL
And guess what. Their classmates solved it. LOL LOL. 😀
Code - and rule the world
