Cryptography and Information Security - Just Cryptography
Cryptography is the art of keeping information secure by transforming it into form that unintended recipients cannot understand. In cryptography, an original human readable message, referred to as plaintext, is changed by means of an algorithm, or series of mathematical operations, into something that to an … See more Before we move into the meat of this article, let's define a couple terms related to cryptography.
