Cryptography; Ancient and Futuristic

When we think about secret codes, images of military intelligence agents in smokey basements decoding the Enigma probably come to mind. However, for as long as there has been the need to transmit information in secret, thereโ€™s been a way to do it โ€” however rudimentary.

In this article, I’ll explore how the ancient methods of encryption have evolved, the security of WhatApp’s end-to-end encryption, and the political anxiety working against progression in the field of encryption.
