Just like with the physical Enigma machine, a key sheet containing daily settings is required.

You are now ready to start using your Python Enigma machine.

Enter the following command to install speak:.

This will install py-enigma, your Pi will notify you of completion with вЂњSuccesfully installed py-enigmaвЂќ The following commands will install py-enigma which is written in Python and the text-to-speech synthesizer, speak.

It will also show how to convert text-to-speech so that decoded messages can be heard through a speaker.

The project uses a software simulator written in Python to encrypt and decrypt messages in a similar way to that used in the original machine. Each time a key was pressed to encode a character, the rotors moved so that the same letter was never encoded the same way twice. Operators were provided with a copy of a monthly вЂњkey sheetвЂќ which contained initial settings for the machineвЂ™s rotors and plugboard, which were changed on a daily basis. The resulting ciphertext character was lit up by a lamp on the board between the rotor and keyboard. Each character was first passed to a plugboard where it was mapped to an alternate character before being fed through a series of rotors, each with 26 characters which produced a further transformation, before feeding it back again by a reflector. It will also demonstrate how to convert text-to-speech using a synthesizer.ДЄn estimated 100,000 Enigma machines were constructed in different versions and this project will simulate the 3 rotor type used by the German army in World War II.Д®nigma machines consisted of a keyboard for typing messages to be encrypted.

This project will turn your Raspberry Pi 400 (or any other Raspberry Pi) into a simulation of an Enigma cryptography machine so you can send encrypted messages to your friends.
