Depends on your threat model.  Which do you consider more of a threat <i>to you</i>, the NSA or a corporate competitor who hired a black hat for some espionage?  Whichever answer you give, there will be people to whom the answer is the opposite.  It&#x27;s not that they&#x27;re being obtuse - that really is the answer <i>for their situation.</i><p>&gt; Don&#x27;t let the perfect be the enemy of the better.<p>Think both&#x2F;and, not either&#x2F;or.
