Cryptography

Learn how cryptography works, the practice of obscuring communication so it cannot be read by an "adversary." Learn about secret keys and hash functions, and cryptography's applications to modern communication, particularly in the online realm.

What is Cryptography?

Cryptography is the practice of secure communication in the presence of third parties. It is a mathematical science that uses mathematical algorithms to encode and decode data. Cryptography is used in a variety of applications, including email, file sharing, and secure communication.
