UK PM wants to ban crypto: here's what it would cost, and why it won't work anyway
This propaganda about good guys backdoors being impossible again. This is cryptographic bullshit of the highest degree. We've had the DUAL_EC scandal, for once, as an example of NSA backdoor which as far as was proved, only the NSA could crack. And with the fact that the NSA had so many bad leaks, yet still everyone except the NSA can't crack it, proved that backdoors are not only possible, but were going on behind our backs.<p>Don't get me wrong - I'm completely against backdoors. But when you shift the argument into "we won't do it because it's impossible", you're already agreeing that it should be done, while your argument won't hold because it is in fact possible.<p>There's three kinds of people: 
1. Non-technical people (theresea may) that want backdoors are don't care about whether it's possible or not.
2. Technical users, with a vague general knowledge of cryptography, and the imprinted thumb rule of "backdoors are bad"
3. People with actual knowledge in cryptography which had  already been doing research about why it is possible for years. Just a teaser: <a href="https://en.wikipedia.org/wiki/Kleptography" rel="nofollow">https://en.wikipedia.org/wiki/Kleptography</a><p>Of course, the real issue would be the scale and the distribution of access to the backdoor to various agencies.
