20 I know it is extremely unlikely that anyone could crack it. My point was
21 that if someone did crack it, they would not necessarily shout about it.
22 If they worked for the security services, that would not want others to
23 know their encryption was insecure. Britain was selling Enigma machines
24 to their "friends" for decades after it was broken.
