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

Banking apps use cryptography to keep your financial data safe.
Privacy Protection
Cryptography ensures that private messages or information remain confidential.

Cryptography keeps your chats private when messaging friends online.
Technical Term
The word is mostly used in technical or professional contexts, not everyday conversation.

As a software developer, I often encounter the term cryptography.

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.

Perianne Boring
American Businesswoman
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.

Quote examples
Nick Szabo
American Scientist
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.

Quote examples
John Paul Stevens
Judge
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.

Quote examples
James Sanborn
American Sculptor
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.

Fred Ehrsam
American Businessman
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 Sculptor
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.

Australian Activist
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.

American Scientist
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.

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.

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.
