Computer security and cryptography

Computer security is an extension of machine engineering, whose goal incorporates insurance of data from unapproved access, disturbance, or alteration while keeping up the availability and ease of use of the framework for its planned clients. Cryptography is the practice and investigation of concealing (encryption) and accordingly decoding (unscrambling) data. Current cryptography is generally identified with software engineering, for some encryption and decoding calculations are focused around their computational many-sided quality.
