This is a short, gentle two-part introduction to basic cryptographic concepts using text-based crypto examples. The videos illustrate encryption, decryption, ciphers, keys, algorithms, code cracking, cryptanalysis, and letter frequency analysis. Full disclosure: I produced these videos over a decade ago.

In theory, a “large quantum computer could quickly crack codes we use every day to protect data. I’ve been skeptical about quantum codebreaking for decades. I [ ]
Journalists aren t usually invited to online chats about US war plans. This seemed obvious until yesterday, when Atlantic editor Jeffrey Goldberg published his article about being a lurker in an online chat with US Secretaries of State, Defense, and Treasury, plus the VP and the Director of National Intelligence.
