Cryptographic methods and development stages used throughout history

Throughout history the need for secrecy has been important. This need for secrecy brought about the invention and the art of concealment, coding and code making [1]. As early as 1900 B.C., Egyptian scribes used hieroglyphs in a non-standard fashion, presumably to hide the meaning from those who did not know the meaning [2]. Cryptography is the effect of designing privacy requirements systems in communication [3]. From the past to the present, many classical encryption methods such as Caesar, Vigenere, and Enigma have been replaced by more powerful modern new encryption methods such as DES, RSA, PGP, AES, and SHA-3.

This study aims to present chronologically together about major cryptography methods and developmental stages in the history of cryptology.
