This video covers this history of Cryptography through the lens of Cryptanalysis. It takes us from the Caesar Cipher to the one-time pad…a daunting task in 8 minutes. My strategy for this was based on much reflection after completing a course in Cryptography last year…I was seeking out the kernel of what is required to understand the big picture. This brought me to analogies which connect the idea of a fingerprint to unique frequency distribution, and information leak to differentials in the distribution. Hopefully this lends some intuitive weight when I explain the strength of the one-time pad…which is a lovely concept.

This video explains why a coin flip is very different from a guess….
Understanding the Probability of Dice, Visually

Great for anyone who hasn’t thought/heard of a probability space:
