english: So he fills in his information, and then after that,  all he has to do is click "send," and just like that, without understanding cryptography, and without doing anything different from how he writes email today, Bob has just sent an encrypted message.
non_english: On popuni podatke i posle toga samo klikne "šalji", i bez razumevanja kriptografije, ne radeći ništa drugačije od onog kako danas piše imejl, Bob je sada poslao šifrovanu poruku.
