Cryptographers use their knowledge of codes and computers to keep data and information safe. Often the job involves cracking-or hacking-codes that encrypt data. Cryptography is the field that looks at how to keep information secure so that only the person who is supposed to see it can.

These example sentences are selected automatically from various online news sources to reflect current usage of the word 'cryptography.' Views expressed in the examples do not represent the opinion of Merriam-Webster or its editors. 2022 At the end of your book, the cryptography professor and tracing pioneer Sarah Meiklejohn expresses trepidation about how this sort of power might be used by oppressive governments. 2014 Both Gosney and Palant take issue with LastPass’ actual cryptography too, though for different reasons. Adam Hadhazy, Discover Magazine, 27 Aug. 2023 Online security today chiefly relies on two encryption schemes: RSA (named for its developers), based on factoring the product of two big prime numbers, and ECC (elliptic curve cryptography), rooted in the algebraic structure of points on a curve. 2022 The vulnerability stems from a basic error in how the cryptography is implemented, but Siemens can’t fix it through a software patch because the scheme is physically burned onto a dedicated ATECC CryptoAuthentication chip. 2023 And because today’s cryptography protocols would be easy work for a quantum computer, researchers have sought new problems to withstand them. 2023 One part of the script generated a key using elliptic curve cryptography and the curve ed25519 for signing files.

2023 TOPLINE Companies like Vector Atomic and Infleqtion are helping the military harness quantum technologies to develop cryptography, underground sensing, secure communications and alternatives to GPS. Recent Examples on the Web In the early ’80s, the IEEE Fellow recalls, computer security consisted primarily of formal verification-using mathematical models and methods-and cryptography, focused on mainframes.
