I don't agree that the user should be first on that list unless you are
talking about poor implementation.
How would you arrange them, then? I seem to recall that Enigma was broken
largely due to sloppy user practices e.g. weak message key, re-use of
keys, repeating same message with a weaker scheme, etc. Used properly,
Enigma would've been unbreakable at the time.
It was so easily broken because of lack of knowledge. Poor
implementation is the enemy.
