ఎన్క్రిప్షన్ ను మొదటగా ఎవరు కనుగొన్నారు?
The Enigma machines are a series of electro-mechanical rotor cipher machines, mainly developed and used in the early- to mid-20th century to protect commercial, diplomatic and military communication. Enigma was invented by the German engineer Arthur Scherbius at the end of World War I. Early models were used commercially from the early 1920s, and adopted by military and government services of several countries, most notably Nazi Germany before and during World War II. Several different Enigma models were produced, but the German military models, having a plugboard, were the most complex. Japanese and Italian models were also in use.
