In a world where political activists and dissidents get persecuted by authoritarian governments, strong cryptography is more necessary than ever. But the general public benefits from it as well. Identity theft, banking fraud and cyber bullying can happen to anybody. The most effective protection is to not make sensitive material available to anybody. Unfortunately some people have an “I have nothing to hide” mentality. But would you post your opened mail to your garden fence? Just because most people are not doing illegal activities, some information is better kept private to stay safe from the aforementioned crimes.
