Two Alexas entertain each other in a cryptographic guessing game that exceeds human intelligence, as well as human patience.


In Knock Knock, two speech-enabled smart devices go head-to-head when one Alexa tries to guess a cryptographic key known only to the other. Their guessing game begins like the familiar children's game prompt, "I'm thinking of a number..." However, this number relies on SHA-256, the same encryption used by blockchain technology. The only way to win is through "brute force," that is, by trying random 64-digit combinations until luck prevails.
