2 definitions found From Webster's Revised Unabridged Dictionary (1913) [web1913]: Cryptography \Cryp*tog"ra*phy\ (-f?), n. [Cf. F. cryptographie.] The act or art of writing in secret characters; also secret characters, or cipher. From The Free On-line Dictionary of Computing (13 Mar 01) [foldoc]: cryptographyThe practise and study of {encryption} and {decryption} - encoding data so that it can only be decoded by specific individuals. A system for encrypting and decrypting data is a cryptosystem These usually involve an {algorithm} for combining the original data ("{plaintext}") with one or more keys" - numbers or strings of characters known only to the sender and/or recipient. The resulting output is known as "{ciphertext}". The security of a cryptosystem usually depends on the secrecy of (some of) the keys rather than with the supposed secrecy of the {algorithm}. A strong cryptosystem has a large range of possible keys so that it is not possible to just try all possible keys (a "{brute force}" approach). A strong cryptosystem will produce ciphertext which appears random to all standard statistical tests. A strong cryptosystem will resist all known previous methods for breaking codes ("{cryptanalysis}").
