Hold on for dear life (permalink)

From the earliest days of technopolitics, the role of technology in resisting authoritarianism was unclear. On the one hand, there's the indisputable fact that modern cryptography, properly implemented, can deliver a degree of privacy that is proof against all technological attacks.

That is to say, if you pull out your distraction rectangle, fire up the camera, and tap the shutter button, in the ensuing eyeblink instant the image you've captured will be scrambled so thoroughly that it could never be unscrambled without the secret key unlocked by your passphrase or biometrics. Even if every hydrogen atom in the universe were converted into a computer, and even if all those computers spent all the time between now and the end of the universe trying to guess what the key was, we would run out of universe and time long before we ran out of possible keys.

What's more, this extremely robust form of scrambling and descrambling can be combined with other techniques to block tampering with the encrypted data, and to allow parties to reliably identify who scrambled the data and also to restrict who may unscramble it. These remarkable technological facts have inspired many excited debates about what they mean for our politics, most notably among a group of people who called themselves "cypherpunks":

One cypherpunk faction believed that modern cryptography could enable a kind of technological secession: by allowing ordinary people to communicate, transact and collaborate without the possibility of state interception or control, crypto could make states themselves obsolete.

But another faction pointed out that no amount of mathematics could help you if an agent of the state – or a criminal the state failed to protect you from – tortured you until you revealed the secret passphrase needed to unlock your secrets. This was (ironically) called "rubber hose cryptanalysis" (as in "Tell me your passphrase or I'll hit you with this rubber hose again"). Later, this became known as a "wrench attack" after a famous XKCD comic about $1m worth of security technology being defeated by hitting someone with a $5 wrench until they divulged the password:

Once you stipulate to the problem of wrench attacks and rubber-hose cryptanalysis, it becomes apparent that your cryptography is only as good as your physical defenses. What's more, the most effective physical defenses we have come from a strong rule of law, because even the thickest safe door benefits from the threat of prison for anyone who breaks into the safe, and the most effective tool for preventing a cop from hitting you with a rubber hose is the existence of a judge who can send that cop to prison for abusing your civil rights.

But what do you do if you already live under tyranny? The rule of law is a great defense, but cryptography alone can't bring about the rule of law. What is the role of technology in this foundational struggle?

My technopolitics faction – the faction associated with the Electronic Frontier Foundation, where I've worked for a quarter-century – has an answer: the role of encryption is to provide a measure of privacy and security that is best used to organize political struggles to demand the rule of law and respect for human rights. Encryption isn't proof against rubber hoses, but it is effective against many other forms of state repression, and it can provide a technical edge for those engaged in a political struggle.

Another faction – the faction most associated with bitcoin and subsequent cryptocurrency projects – rejects the role of the state altogether, and seeks to replace states (and state-regulated institutions like courts and banks) with mathematics. Rather than asking courts to interpret contracts, we can put our trust in self-executing "smart contracts," and rather than asking banks to safeguard our financial integrity, we can use cryptographic software to ensure that money only moves when the person it...
