Is good when hacking enemy and through enemy nodes. As UC endgame, it's pretty basic to have ALL your systems encrypted just to spite people and use up that BW that generates influence for you. It serves as defensive measure against enemy hacking, and can be turned off anytime if you run out of bandwith, so basically 'SPAM THIS!' especially on border nodes. Encrypt makes you slow enemy hacking on the node by 50%, Using ANY defensive program on a node removes backdoors on it. I'll highlight the ones you should use the most, others are mostly situational, but are under no means useless, but are also selfexplanatory. ProgramsRange from 'SPAM THIS!' to 'Meh'.
