Cryptography is the art of creating mathematical assurances for who can do what with data, including but not limited the classical example of encrypting messages so that only the key-holder can read it. Cryptography lives at an intersection of math, programming, and computer science. This subreddit covers the theory and practice of modern and *strong* cryptography, and it is a technical subreddit focused on the algorithms and implementations of cryptography.
