cryptography, known as Kautiliyam and Mulavediya. The province of Sassanid, Persia had two kinds of secret scripts: one used for official purpose and one for foreign communication.
Any article about crypto system is incomplete without the mention of the legendary Alan Turing and the famous Enigma Machine. Enigma was the almost flawless German cryptography machine which worked on the principle of electromechanical rotor mechanism. It scrambled all letters present in a word, and the huge number of possibilities generated by it made the decryption process extremely difficult. It was famously used by the Nazis in the German Military during World War II. Excessively complicated and easily portable, it was one of the main weapons of the Germans. In fact, it seemed almost unbreakable. The only possible flaw with the machine was that it never encoded a letter by itself. In other words, the encoding function of enigma had no fixed points. This was a major hint for

the code breakers.
Alan Turing, the brilliant Cambridge
University Mathematician, Computer Scientist, Cryptanalyst, and Philosopher, was the first to break the Enigma code. Victory of the Allied Force in WWII can be credited to Turing for his
pioneering decryption technique, which revolutionized cryptography. Thus, secure encryption techniques that are used in WhatsApp profiles of individuals today were once used as a principle weapon in one of the most deadly wars ever fought in the human history!
