Generally the entropy is derived from the timing of the interrupts from the keypresses. The actual output of keys pressed isn't terribly useful.

  Huh, I wouldn't have guessed that, but I suppose it makes sense- people usually follow patterns on keyboards.

    I guess those pattern get broken once someone uses a dvorak keymap (like I do) and the person analyzing the text doesn't know.

    Yeah, and the last couple bits of the microsecond timestamp on the interrupt that fired when the key pressed are going to be pretty darn random.
