Cryptography is a method of storing and transmitting data in a form that only those it is intended for can read and process. It is considered a science of protecting information by encoding it into an unreadable format. Cryptography is an effective way of protecting sensitive information as it is stored on media or transmitted through un-trusted network communication paths.
One of the goals of cryptography, and the mechanisms that make it up, is to ...
