Encryption and it's role towards a more independent society, free from a coercive all-knowing big brother state:

"The universe believes in encryption.

It is easier to encrypt information than it is to decrypt it.

Scientists in the Manhattan Project discovered that the universe permitted the construction of a nuclear bomb. This was not an obvious conclusion. Perhaps nuclear weapons were not within the laws of physics. However, the universe believes in atomic bombs and nuclear reactors. They are a phenomenon the universe blesses, like salt, sea or stars.

Similarly, the universe, our physical universe, has that property that makes it possible for an individual or a group of individuals to reliably, automatically, even without knowing, encipher something, so that all the resources and all the political will of the strongest superpower on earth may not decipher it. And the paths of encipherment between people can mesh together to create regions free from the coercive force of the outer state. Free from mass interception. Free from state control.

In this way, people can oppose their will to that of a fully mobilized superpower and win. Encryption is an embodiment of the laws of physics, and it does not listen to the bluster of states, even transnational surveillance dystopias.

It isn't obvious that the world had to work this way. But somehow the universe smiles on encryption.

Cryptography is the ultimate form of non-violent direct action. While nuclear weapons states can exert unlimited violence over even millions of individuals, strong cryptography means that a state, even by exercising unlimited violence, cannot violate the intent of individuals to keep secrets from them.

Strong cryptography can resist an unlimited application of violence. No amount of coercive force will ever solve a math problem."
