Cryptography Quotes

Encryption, trust, and control

These cryptography quotes describe encryption as a real, practical way to keep control over your own files rather than trusting other people with them.

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.

Quotes by Whitfield Diffie

I thought cryptography was a technique that did not require your trusting other people-that if you encrypted your files, you would have the control to make the choice as to whether you would surrender your files.

Quotes by 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.

Quotes by Whitfield Diffie

I think that the people who are trying to shut down WikiLeaks are going to have to accept this as a fact of reality that cryptography allows you to do this kind of thing.

Choice Quotes

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.

Quotes by Naval Ravikant

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.

Quotes by James Sanborn

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.

Frequently Asked Questions

What do these cryptography quotes focus on?
They focus on encryption as a practical tool for personal control and privacy, plus how quickly public key cryptography became mainstream.
Is WikiLeaks mentioned specifically?
Yes, one quote frames cryptography as a fact of reality that lets information spread even when authorities try to shut down sites like WikiLeaks.
What personal benefit does cryptography offer, according to these quotes?
One quote says encrypting files lets you keep control over whether to surrender that data, rather than needing to trust other people.
Is there criticism within the cryptography community mentioned?
Yes, one quote observes that some people working in cryptography care more about clever, paper-worthy problems than real application issues.
Where can I find related quotes about technology and control?
See the Control quotes page for more on this theme.

Others reflect on how fast public key cryptography moved from theory into everyday communication, while noting some researchers chase clever codes more than real-world use.
