In the last couple of years, a meme that's come to be known as security nihilism has appeared in the security community. In a nutshell, because there is no such thing as perfect security, there is no security at all, so why bother? Talking about layered security controls that reinforce each other is pointless because they always skip right to the end, which is the circumvention of the nth countermeasure and final defeat. In the crypto community, cries of "Quantum computer!" are the equivalent of invoking Godwin's Law, leading to the end of all discourse, nevermind trying to separate the marketing hype from what's actually possible or the decade-odd of research into post-quantum cryptosystems. This has lead to a certain amount of attrition in the community. It is my considered opinion that this may be one of the main reasons why many so-called security practitioners don't actually bother doing anything, including not even installing patches. No, I'm not speaking hyperbolically, I've witnessed this first-hand I'm sorry to say.
UPDATE - 20170228 - Added more stuff I've discovered about KBFS.
A couple of years ago you probably heard about this thing called Keybase launching with a private beta, and it purported itself to be a new form of public key encryption for the masses, blah blah blah, whatever.. but what's this thing good for, exactly? I mean, it was pretty easy to request an invite from the service and either never get one, or eventually receive an e-mail and promptly forget about it. I've been using it off and on for a while, and I recently sat down to really mess around with it and get a sense for how it's changed and what it can do. Plus, there's a fair amount of outdated or bad information floating around out there, and I wanted to do my part to set the record straight.
I'm not going to spend time explaining public key crypto because I wrote a pretty decent introduction to it that I give at cryptoparties. Take a look at the PDF of the presentation; I tried to make it as painless as I could. I want to keep this post focused on Keybase.
