 Cryptography, or cryptography (from Ancient Greek: κρυπτÏŒς, romanized: kryptós "hidden, secret"; and γράφειν graphein, "to write", or -λογία -logia, "study", respectively[1]), is that the observe and study of techniques for secure communication within the presence of third parties known as adversaries.[2] additional usually, cryptography is concerning constructing and analyzing protocols that stop third parties or the general public from reading non-public messages;[3] numerous aspects in data security like information confidentiality, information integrity, authentication, and non-repudiation[4] area unit central to fashionable cryptography. fashionable cryptography exists at the intersection of the disciplines of arithmetic, computing, technology, communication science, and physics. Applications of cryptography embrace electronic commerce, chip-based payment cards, digital currencies, laptop passwords, and military communications. Cryptography before the fashionable age was effectively substitutable with secret writing, the conversion of data from a decipherable state to apparent nonsense. The creator of AN encrypted message shares the secret writing technique solely with meant recipients to preclude access from adversaries. The cryptography literature typically uses the names Alice ("A") for the sender, Bob ("B") for the meant recipient, and Eve ("eavesdropper") for the human.[5] Since the event of rotor cipher machines in war I and therefore the advent of computers in war II, the ways accustomed perform cryptography became {increasingly|progressively|more and additional} complicated and its application more widespread.
