Only a small fraction of the information flowing around the world is securely encrypted, and the remainder is poorly encrypted, or not encrypted at all. This is because the number of Internet users is rapidly increasing, and yet few of these people take adequate precautions in terms of privacy. In turn, this means that national security organizations, law enforcers and anybody else with a curious mind can get their hands on more information than they can cope with.
