Through decentralized cryptography, Bitcoin eliminates the need for banking intermediaries, significantly lowering transaction costs, and could liberate poverty-stricken economies around the globe by providing access to capital to the one-third of humanity that is excluded from the financial world.

With original cryptography, you are just trying to secure one narrow thing - say, communications - and you are trying to secure it from a third party. But you can't secure it from the party you are talking to if they forward your email; it doesn't matter how well your email is encrypted.

American Scientist

John Paul Stevens

Of course, when I joined the Navy and when I took up the correspondence course in cryptography, I had to sign an oath that I would never reveal what sort of work I was involved in. It was only some years after the war that Congress passed a statute relieving me of that obligation.

Judge

James Sanborn

I chose to deal with the science of cryptography. Cryptography began in mathematics. Codes were developed, even from Caesar's time, based on number theory and mathematical principles. I decided to use those principles and designed a work that is encoded.

American Sculptor

Fred Ehrsam

When the Bitcoin white paper emerged in 2008, it was completely revolutionary. The amount of concepts that had to come together in just the right way - computer science, cryptography, and economic incentives - was astonishing.

American Businessman

What affected me most profoundly was the realization that the sciences of cryptography and mathematics are very elegant, pure sciences. I found that the ends for which these pure sciences are used are less elegant.

Julian Assange

Cryptography is the essential building block of independence for organisations on the Internet, just like armies are the essential building blocks of states, because otherwise one state just takes over another.

Australian Activist

Whitfield Diffie

I understood the importance in principle of public key cryptography but it's all moved much faster than I expected. I did not expect it to be a mainstay of advanced communications technology.

Naval Ravikant

A block chain is a series of blocks. Each block is a series of computations done by computers all over the world using serious cryptography in a way that's very hard to undo.

Businessman

Lots of people working in cryptography have no deep concern with real application issues. They are trying to discover things clever enough to write papers about.

Cryptography is used to protect information so only intended people can access it.

Secure Communication

Cryptography ensures that private messages or information remain confidential.

Privacy Protection

The word is mostly used in technical or professional contexts, not everyday conversation.

Technical Term

 They mailed the letter back to themselves. Then they examined the letter looking for the DNA strand. Once the DNA strand was located, they found the genetic markers. Then, they sequenced the DNA and successfully decoded the message. It soon became obvious that DNA cryptography could code for much more than simple text.

Is DNA the future of...

 the cryptography to do that not only exists, it's extremely well-known and well-understood. Digital signatures, the blinding of public key certificates -- these technologies have been around for a while, we've just had no way of packaging them up. So the technology already exists. We know it works.

David Birch: A new way...

 Unlike all of the prior methods used throughout history, it doesn't require that the two parties that want to send each other confidential information have exchanged the secret key beforehand. The magic of public-key cryptography is that it allows us to connect securely with anyone in the world,

 one of the first quantum algorithms was found for finding the prime factors of very large numbers and that's important because that means that a quantum computer would break RSA cryptography which is a gold standard and in widespread use today and while these

 who had boasted that none of his work would ever be found useful in describing any phenomena in the real world, helped establish cryptography. Another piece of his purely theoretical work became known as the Hardy-Weinberg law in genetics,

 in our macroscopic world, like in quantum cryptography, so spies can send secure messages to each other, or quantum computing, for cracking secret codes. Everyday physics may start to look a bit more like the strange quantum world.

 Cryptocurrencies are based on a special field of mathematics called cryptography. Cryptography is the study of how to secure communication, and it's about two really important masking information so it can be hidden in plain sight,

 that stores a registry of assets and transactions across a peer-to-peer network. It's basically a public registry of who owns what and who transacts what. The transactions are secured through cryptography,
