Cryptography is the study of ways to convert information from its normal, comprehensible form into an obscured guise, unreadable without special knowledge — the practice of encryption. In the past, cryptography helped ensure secrecy in important communications , such as those of spies , military leaders, and diplomats .
Cryptography is also a branch of engineering, but an unusual one since it deals with active, intelligent, and malevolent opposition; other kinds of engineering (e.g., civil or chemical engineering) need deal only with neutral natural forces. There is also active research examining the relationship between cryptographic problems and quantum physics.

Cryptanalysis has coevolved together with cryptography, and the contest can be traced through the history of cryptography—new ciphers being designed to replace old broken designs, and new cryptanalytic techniques invented to crack the improved schemes. In practice, they are viewed as two sides of the same coin: secure cryptography requires ...
Cryptographic protocols — the communication protocols designed and available to provide computer security assurances using cryptographic mechanisms.. Classic assurances include internet protocols for confidentiality and message integrity — and more recent research includes anonymity assurances.
