Cryptography, in the world of computers, refers to techniques and processes for making information securely private so that it can only be accessed by authorized people or devices. Cryptography underpins many applications such as cryptocurrency, cybersecurity, secure messaging, digital signatures, digital rights management (copy protection), and more. The shortened term crypto generally refers to a subset of applications such as cryptocurrencies and non-fungible tokens (NFTs).
