Enigma-CLI

Welcome to Enigma Machine.

What is it?

The Enigma machine is a cipher device developed and used in the early- to mid-20th century to protect commercial, diplomatic, and military communication. It was employed extensively by Nazi Germany during World War II, in all branches of the German military. The Germans believed, erroneously, that use of the Enigma machine enabled them to communicate securely and thus enjoy a huge advantage in World War II. The Enigma machine was considered to be so secure that even the most top–secret messages were enciphered on its electrical circuits.

This project is emulator of real enigma machine. For more information and enigma works please read wikipedia.

Information

The Wehrmacht used the following abbreviations:

• KLAM = Parenthesis
• ZZ = Comma
• X = Full stop (end of sentence)
• YY = Point or dot
• X****X = Inverted commas
• Question mark (Fragezeichen in German) was usually abbreviated to FRAGE, FRAGEZ or FRAQ.
• Foreign names, places, etc. are delimited twice by "X" as in XPARISXPARISX or XFEUERSTEINX
• The letters CH were written as Q. ACHT became AQT, RICHTUNG became RIQTUNG
• Numbers were written out as NULL EINZ ZWO DREI VIER FUNF SEQS SIEBEN AQT NEUN. It was prohibited to encipher the word "NULL" several times in succession, so they used CENTA (00), MILLE (000) and MYRIA (0000). Some examples: 200 = ZWO CENTA, 00780 = CENTA SIEBEN AQT NULL

Authentic Wartime Message from the Russian Front

The message was sent by the commander of the SS-Totenkopf Division (SS-T), also known as 3 SS-Panzergrenadier-Division Totenkopf, a division of the Waffen-SS. The message was destined to the LVI (56) Armee Korps. In April 1941, SS-T was ordered east to join Heeresgruppe Nord, which formed the northern wing of operation Barbarossa, the campaign against Russia. SS-T saw action in Lithuania and Latvia, and breached the Stalin Line in July 1941. The message from July 7 contains a situation report on SS Panzer Regiment 3 and its 1st Battalion.

The settings as recovered by the CSG codebreakers:
