Cryptography simple definition

WebEarly 20th century cipher wheel. Cryptography, [1] or cryptology, is the practice and study of hiding information. It is sometimes called code, but this is not really a correct name. It is the science used to try to keep information secret and safe. Modern cryptography is a mix of mathematics, computer science, and electrical engineering. WebFeb 27, 2024 · Cryptography is the method which protects data using codes (like hashing and encryption.) Developers apply cryptography whenever there’s a need for higher security and privacy. It transforms plain text (or other data) into an unreadable string of random characters. This guarantees information security from prying eyes.
