    Just to preempt the peanut gallery here, I am using "hash" in a very loose sense here to encompass any "one-way" destructive transform that is highly resistant to chosen collision attacks. Note that, for this particular application, the input field can be restricted and the output field expanded to make such attacks infeasible or even impossible (probabilistically impossible, in an asymptotically approaching zero percent chance of a collision even existing sense of the word).

    I once had someone try to "prove" me wrong using a single invocation of whatever CLI version of SHA they had lying around. That's not the point at all. I don't care about quibbling over terminology; I care about it being 2016 and simple database breaches of login credentials routinely causing massive direct and indirect damage.

    The "actual reality" is that companies cannot be trusted to perform the hash properly on their end and several have openly admitted to losing plaintext passwords. The actual reality is hashing is not all that computationally expensive in today's world, and many modern processors have specialized instruction sets that could be exploited for this purpose. The actual reality is that hashing, in the general sense of the term, does not need to significantly decrease entropy (though obviously improperly implemented hashing can.)

    The "actual reality" is that client-side hashing is easily auditable, whereas properly implemented server hash (in combination with a finite limit on the password field) prevents a read-only database breech from instantly translating into access to all accounts (although it does enable offline attacks, so everyone with weak passwords will be compromised as soon as the attacker can get around to cracking their hash.) None of this would interfere with a challenge-response scheme or any other additional security measures from being implemented, if one wished.

    The actual reality is that measures such as these would have significantly mitigated a lot of the damage and collateral damage from many of the high-profile breaches we've seen in recent years.

    It allows anyone to encipher messages without any possession of secret information.

    Yes, but it's worth noting this doesn't allow you to encipher information without preshared information. You require CAs and such to be pre-loaded and trusted ahead of time.

    If you've made that leap of trust, why not make a much easier leap of trust of using a friend's connection get your initial set of symmetric keys? Why not use an automated telephone service, and a little slip of paper that came with your new computer?

    The "secret information" is, in fact, very easy to come by and only needs to be done once. All keyservers would need to be compromised for the session to be compromised, and because it's stateful and there's no reason not to immediately generate new keys for each server you talk to, that compromise would have to be retroactive (i.e. based on some logs someone has been stealthily maintaining on ALL keyservers used) for it to be a truly catastrophic breach.

    This can be used on top of or alongside asymmetric solutions for the exceptionally lazy, paranoid and/or ignorant. By all means, if you want to put 100% of your trust in your magical "one-way" mathematic functions remaining one-way for your entire lifetime, you should be free to. I am only addressing those readers who would give a damn about pursuing a truly robust system, one that isn't vulnerable to a single RSA weak key class discovery or a single rogue CA to bring down.

    Nothing you offer does that when you remove the shell game of punting of responsibility and convenient ignoring of underlying reality.

    The "underlying reality" is we've already needed to increase the size of RSA a few times, and ban various classes of weak keys. That's because with any system where the asymmetric key is the weakest link, you are always playing with fire because you have to assume that no shortcuts in the future will be found.

    For a zero known plaintext attack of encryption of random data (as would routinely occur in a WOT symmetric key exchange system), we're as certain as certain can be that symmetric algorithms are secure. Such a scheme is literally the most robust scheme imaginable short of an OTP.

    We have no good reason to be nearly so confident about RSA or other asymmetric solutions remaining similarly secure a decade from now, even in the absence of quantum computers.

    It allows this to occur in a completely untethered, unlimited and untraceable manner.

    Vague hand-waving nonsense. There is no tethering or limit or tracing involved in my system except for the very first time you need a set of keys. For an organized person, this is literally a once in a lifetime process. For a less organized / knowledgeable person, this would only need to be done every time a new device was purchased.

    Please don't tell me you're about to drag out some nonsense about being "limited" to the amount of non-volatile you have at your disposal.

    We know nothing of the sort. There is ZERO evidence in existence to support this assumption. NONE.

    Ok, uh, well they have implemented Shor's algorithm. They know for a fact that it works. And they've been using it on progressively larger numbers. Yes yes, those numbers are still very small. But building a proof of concept device, and then watching as the underlying tech improves and the proof of concept devices become a little stronger (if still miles away), does not constitute "zero proof". It means we can be certain it's not impossible in principle, and it also indicates that researchers haven't lost interest yet.

    Prior to one of their bigger leaks (possibly the Diplomatic Cables one, I forget), Wikileaks asked the USA gov to help sorting out the sensitive information. They refused. Whether you want to admit it or not, the USA is also the reason why Assange is holed up in an embassy. What he may or may not have done in Sweden is irrelevant; America refuses to offer any assurances that Assange will not be taken into custody (for doing his job as a reporter, albeit not always entirely competently).

    So I really think we need some middle ground between "good reporter" and "bad reporter" here. I think "harrowed reporter" and "intentionally sabotaged by Washington reporter" are useful terms to introduce as well.

    It's a bit disingenuous of you to imply the Cablegate thing was purposefully engineered by Assange. He may not have handled the encryption as well as he should've, but he wasn't the one who revealed the decryption key to the world. And if he wasn't threatened by Washington to begin with, he never would've needed his "insurance" files and he might have had more time to properly vet and properly distribute the material to newspapers.

    At this point, I really don't begrudge Assange a bit of spite. He gave America plenty of chances to play fair and abide by its own first amendment, and Hillary responded by asking (perhaps half-jokingly) if we couldn't "just drone this guy?"

    So, um, fuck her, fuck the people who work for her, fuck you for thinking that revealing a bit of office gossip is at all important for us to be worrying about, and fuck you again for blaming Assange for every one else's fuckups (including but not limited to the reporters who openly revealed the passphrase for the cables.)

    Asymmetric schemes are as a practical matter absolutely necessary.

    No they aren't, as I've explained at length in other posts. Web of trust approaches combined with intelligent hashing can be used to automatically generate session keys known only to the two parties without any single point of failure (all of the trusted servers would need to be compromised) and without any need for manual intervention.

    The only thing asymmetric buys you, in terms of hassle for the end user, is the ability to not to have to worry about a transferring around a (fairly small) master keyfile or passphrase. But even this initial setup could be easily accomplished using a trusted friend's secure connection, either locally or you call them up on the phone and exchange a shared passphrase that way. An automated system can be set up by phone for people to bootstrap off of.

    If your going to ask others you have no control over to "get to work" on something you kind of have to provide compelling evidence to support your position if you expect anyone to pay attention to you or spend their time on it.

    The tone of my post made it fairly clear, I thought, that this was obviously a futile argument. Even if I had highly compelling evidence and thirty years of experience, it still would probably be a lost cause due to the massive amounts of laziness and inertia involved here. I'm lamenting our inability to adhere to the precautionary principle. It would be so easy, in principle, to supplement the current system but in practice it'll never happen.

    We know a quantum RSA break is simply a matter of time. We don't know what tech advances will suddenly appear in the future, but we do know that if any country had a breakthrough there would be a very strong incentive to invest billions into it, even if they just got a few years' work out of it. And even it never happens, for whatever reason, asymmetric computing has always had many more question marks hanging over it. We can't be sure there won't be a new class of weak RSA keys discovered tomorrow, but we can be fairly confident that a powerful (i.e. much faster than brute force) zero-known plaintext attack for AES is not going to pop up tomorrow.
