Bruce Schneier, acerca de por qué es importante que todas las comunicaciones estén encriptadas, siempre:
Encryption should be enabled for everything by default, not a feature you turn on only if you’re doing something you consider worth protecting.
This is important. If we only use encryption when we’re working with important data, then encryption signals that data’s importance. If only dissidents use encryption in a country, that country’s authorities have an easy way of identifying them. But if everyone uses it all of the time, encryption ceases to be a signal. No one can distinguish simple chatting from deeply private conversation. The government can’t tell the dissidents from the rest of the population. Every time you use encryption, you’re protecting someone who needs to use it to stay alive.
