(For those who aren't familiar with it: SIGABA was the US military's extremely secure rotor-based cipher machine during World War II. When one went brieflymissing, it caused a panic, not because they thought it would help the Germans crack the US cipher, but because they didn't want to teach the Germans how to build a secure rotor machine.)

@SteveBellovin To all: and the main difference with Enigma, apart from having 5 rotors (and not 3 or 4), is that the rotor movement is created by another set of rotors whereas Enigma was mostly regular (mostly because there were pins to disturb the movement).
