Caesar Cipher

Description: In this unit we learned about a method of encryption/decryption in Python code. This method included having a key, the amount of letters by which you would shift each letter in your message.

Procedure: We started off by learning how to encrypt and decrypt using a single-digit key.

Then, we learnt how to take it a step further so that it takes more guesses for a hacker to crack. We used the same foundation of code as the single-digit encryption/decryption and added changes.

The Missing Cow: In this fun, challenging problem, we had to use a set of clues and our Caesar Cipher code to find out where Ms. Tran's missing cow went. This was a partner-work activity, and I was with Max.

After decrypting four messages, we were given a fifth message and an incomplete 10-digit key. Using the first four clues, we had to find out the last few digits of the key.

SOUL Reflection:

S - The strength of my work, in my code and finding the cow, was staying determined even when things got confusing.

O - An opportunity to improve my work in this unit was to find time outside of class to fix any nonfunctional code.

U - In this unit I learnt about how you can combine for loops and if statements to achieve a lot.

L - Limitations I encountered were being stumped on the last few digits of the final key in the missing cow game. Eventually, we ended up having to brute-force it, which was time-consuming.

WISCR:

I think that the two qualities of WISCR I exemplified were clear communicating and respectful individuals of character. I showed clear communicating through being on the same page as my partner and asking Ms. Tran for help when I needed it. I exemplified being a respectful individual of character by helping my classmates, while still having boundaries.
