WebMar 22, 2024 · Introduction to Crypto-terminologies. Cryptography is an important aspect when we deal with network security. ‘Crypto’ means secret or hidden. Cryptography is the science of secret writing with the intention of keeping the data secret. Cryptanalysis, on the other hand, is the science or sometimes the art of breaking cryptosystems. WebCryptography Definition Cryptography is the study of secure communications techniques that allow only the sender and intended recipient of a message to view its contents. The term is derived from the Greek word kryptos, which means hidden.

Topics include symmetric and public-key encryption, message integrity, hash functions, block-cipher design and analysis, number theory, and digital signatures. Overview WebIn cryptography, a salt is random data that is used as an additional input to a one-way function that hashes data, a password or passphrase. Salts are used to safeguard passwords in storage. Historically, only the output from an invocation of a cryptographic hash function on the password was stored on a system, but, over time, additional …

WebCryptography is the use of a series of complex puzzles to conceal and uncover messages. Equations and computer coding convert plain, readable data into a format that only an authorized system or person can read. This allows the information to remain secure and enables parties to send and receive complex messages.
