Thanks for the great video! You explain really well. At 5:32 - the answer to the first exercise seems to have one incorrect letter. "MOVE TO HIGH GROUND". Should the first and last letters of HIGH be the same in ciphertext also?
Oops. You are quite correct. Of course the fundamental flaw of the Caesar cipher is that the same plain text letter will result in the same ciphertext letter. :)KD
My name is Kevin Drumm. I'm head of computer science at a secondary school in the UK. I haven't made any MOOCs yet, but I will be looking into it in the future. :)KD
Could you please do it where there are one set numbers on the inner section as part of a cipher wheel, encrypting and deciphering numerical cipher text? - I’ve been quite fascinated by it since seeing it in the Enola Holmes film.. I want to figure out some of the codes myself. 🕷:’)
It is the best course about cryption on UA-cam. Thank you, awesome teacher.

Nice videos, I've watched a couple.
It would be nice if you put the strings (sample input) in the description for people coding along here.
What is the name of the teacher of this course? Has he got any course in MOOC? Can I be certified from the official courses of this teacher?

Me after decrypting the first secret message: 😳

I'm watching this so I can figure out some of the messages in my gravity falls journal
