Yes, the users have been here for a long time. They are hanging around in the corner trying to talk to the guy who just seems like such a dick, but in fact is just unable to talk to people who don't speak his lingo, and he is not interested in talking to them.

Ultimately some people will want to talk to him, and other won't, but at least get over the awkward introductions.

While you've probably got a really good reason for saying 0) and 1) above, I'd like to hear them, just because I used to think similar things as 0) and 1).

The more I have been reading about [NORMAL USERS] the more I think we (the people who know about the complicated shit) are not going to save them all. It may sound disingenuous to say but, there is no point trying. Humans are humans. Getting people to think themselves about these topics it a lot more successful than giving them tools and hoping they use them.

I'm surprised to hear you say everything that requires user education fails. I (think) I know your reasoning.

(This may sound insulting, but its not meant to.)

Absolutely 100% completely agree. It should have been peer-reviewded from the start.

It was (IMO) wrong, and slightly misguided to write a handbook which is ultimately about a complex and technical set of topics, without having some expert advice or input. That is not to insult the work the people did. I just think it was executed incorrectly.

To continue my previous self-bashing thread, technical people need to be more easier to deal with. We need to be more intelligent in how we explain what are complicated subjects. 

Saying "data confidentiality, authentication, threat-model, non-repudiation," to most people means squat. As someone explained, "every time you walk across a road, you make a threat-model/assessment" makes more sense.
 
We also need to understand that most people don't really care about the super complicated stuff thats involved in crypto/security.

On the other hand, to bash the people who are not crypto/security experts, they have to understand that the subjects are involved are complicated, not easily reduced. They also need to understand the implications of giving wrong/bad information.

They also need to know when something the technical people say is not just hot-air, or BS.


One giant PDF for this cryptoparty handbook was the wrong approach. It should have been Git or a closed wiki. It should have been broken down into chapters and had people who know about the topics working on it too. Sure it would have taken more time, but it would have saved all this thrashing about.

Git is not something most people would want to use (or indeed heard of) but for an editing process its a good option. There should have been a change log all the while. 

When its finished, or ready for purpose, then publish it in PDF/mobi/whatever.


Learning how crypto / security works is not rocket science. Anyone can learn the approaches used, the right or wrong ways to do something. You may not become a leading developer of it but thats ok. Not everyone will.

People can learn how to install PGP, Enigmail, the Tor browser bundle, Truecrypt, but if they aren't educated on how best to use them (to think for themselves) then the cryptoparty is wasting their time.

I was present (and helped out a bit ) at the Tor talk the London crytoparty and it was wonderful to see discussions with the "non-technical" (I hate saying that but I don't know what else to say) people who attended to Tor talks. They were thinking about things. They just needed some help.

It was clear to see there were people present who had thought about these tools. Their issue was not "Should I should use this?", it was "How the fuck do I know when/where to use it?"

The list of topics you added above, to me, are topics that show cryptography and security is not just about whizz-bang technical stuff - they are about looking at a subject critically, with rational thought and making decisions based on logic rather than trust or "it'll be ok.

Once you understand the threats, then you yourself can come to a decision as to what tool is right for the job.
