What Is Cryptography? Definition & How It Works Okta
WebApr 21, 2024 · Cryptography is used to keep messages and data secure from being accessible to anyone other than the sender and the intended recipient. It is the study of communications and a form of security for messaging. Ultimately, cryptography can keep data from being altered or stolen. It can also be used to authenticate users. Cryptographic hash functions are cryptographic algorithms that generate and use keys to encrypt data, and such functions may be viewed as keys themselves. They take a message of any length as input, and output a short, fixed-length hash , which can be used in (for example) a digital signature.
