WebKey Highlights. Cryptography is a field of math and includes the study of encryption, hash functions, and digital signatures. The Bitcoin network uses hash functions to ensure the blockchain’s security and immutability. Bitcoin uses public key-based digital signatures to allow users to send bitcoin trustlessly. WebIn cryptography, a key is a piece of information used for scrambling data so that it appears random; often it's a large number, or string of numbers and letters. When unencrypted data, also called plaintext, is put into a cryptographic algorithm using the key, the plaintext comes out the other side as random-looking data.
