HIPS (Hidden In Plain Sight) Communicator is both a fun app, and a way to protect free speech in private groups or between a select group of people. It uses a very simple, random word rotation, but with a base English word list of more than 77,000 words. What this does is offer a potential for more than 6 BILLION possible unique keyfile possibilities, meaning your conversion key is fairly safe against prying eyes.
Tired of unsolicited opinions? Fact checkers? The censorship police? Then have some fun with your circle of contacts, and keep your personal communications personal.
