During Hank's Windows 11 first look presentation on 8 July, the idea came up: Would anyone be interested in a lecture from me about the basic theory of cryptography, and how it applies to real world problems?
My presentation would include specific examples in Python that you can try at home (and of course I'll publish the notes and code ahead of time).
Jerry also said asked if we could include steganography in the discussion. What other topics should this lecture cover?
