There is another point to this which is not being said. A number of years ago a Swiss guy invented a form of encrypted communications using laser light that while not impossible to crack did tell you if someone had tried to intercept your signal and therefore you could at least assume the message is no longer secret.


 


This was Aussie but I am sure the orig was Swiss
