Hello.I read your posts OP, and I've read similar ones before by well meaning individuals. You are, well, wrong. Kmfkewm has already explained why in great detail. But it is more interesting why you are wrong than why containing with current practices is correct. There is in fact a huge space for a creative mind to develop useful solutions to this problem, but maybe they are not what you might initially think of as cryptography.If the objective is to spread the use of strong asymmetric cryptography then there are three possible vectors that affect this.1. Technical. Is the strength of the cryptosystem good enough? More importantly, is the design of the cryptosystem standing up to attacks over time?2. Human Computer Interaction. Many crypto applications have a powerful back end but confusing graphic user interfaces for the non geek.3. Psychological. Why do people wish to learn this? How can we motivate them? In a word: education.--It is my belief that people don't use crypto, not because they have made a value judgement on the technical side, but because they are either frustrated by the usability of the product or they are scared off by techno-fear (commonly experienced by true music lovers). However even this is dwarfed by the psychological aspect. In a way it is more difficult to create a learning system than a cryptographic system. The learning curve in a population doesn't spread exponentially, and the use of public key cryptography requires knowledge, often called tradecraft in our field. It is a similar problem to how people need to know how to use a telephone in order to communicate long distance. You can have as many telephones as you wish in people's homes, but without each user understanding how and why you'd be motivated to use one telecommunications would never have scaled up.Essentially you need to either create new usecases (which in a way I believe SR has accomplished for PGP) or you need to demonstrate them in such a way that learning PGP becomes a meme. PGP Propaganda :)The single best way to achieve that is to make use of PGP a rite of passage. People who don't use PGP are to be mocked relentless for their foolishness, and people that do are to be made to feel as part of some special group. Thus PGP Club. And it is not lies. The propaganda I mean. Knowing PGP really is an exclusive club. PGP is used by cryptographers, intelligence officers, the military, drug vendors, political revolutionaries and monotremes. Conversely people not using PGP on here really are being idiots.Thought experiment: Let's say LE hackers break into SR. If we all use PGP, nobody cares. If we don't, we're fucked. That is why SR is still here, it is because it is completely immaterial to outcomes whether you hack into it. It or it's competitors would be back up in days or weeks, and the network would reassert itself as if nothing had occurred. Network wise, DPR is just another person logging on via Tor. Taking out a 'boss' doesn't work either. The only real reason you harden your servers is that a percentage of the buyers imagine hardening them makes a difference. The LEO tasked with bringing down SR knows this. It also knows that every media rag on the planet will be saying only the people who didn't use PGP got busted, not exactly the news story they wish printed.LE agents have the plan to drag the entire plant up, roots and all by assiduously accumulating information in the hope they will achieve something akin to a breakout point, a panic, a reaction that will sustain itself. Reasonable goals. Unfortunately for them they are fighting precisely the kind of war they do not understand, that they find unacceptable due to their institutional infrastructure. Tor, Bitcoin and SR are ideas, and more than just normal memes, they are exemplars. An exemplar meme is one that forms the shape of other memes to come, like a root word. Such memetic warfare always lasts decades or even centuries, something that is impossible for centralized organizations to commit to consistently without being authoritarian. That pops them onto the horns of a terrible dilemma. Anyway, I'm drifting away from my point.So you don't sell 'serverside PGP'. It is so easy to use. Yay. Nobody will give a shit apart from the ignoramuses that use iGolder or Hushmail or any other law enforcement honeypots. It would actually be more secure, not less, to send your address as plaintext than to use those services.Instead, sell James Bond. Sell Che Guevara and leet hackers. People are excellent mimics and learn quickly when they think something is cool or useful. I have the height of respect for cryptographers who engineer our algorithms like RSA, but this is a not that kind of problem or quite frankly it would have been solved long ago given the quality of brainpower directed at it.tldr; It's not just a bad idea for technical reasons. Who cares about a perfect product nobody wants to use?
