ENIGMA MACHINE SIMULATOR

This app simulates coding and decoding of messages with an Enigma machine in Python/Django.

URLS

Two URLS are available in this version: one to encode messages and one to decode messages.

Encoding

To encode messages, go to

enigma/encode/<message>/<date>/<indicator_key>/<message_key>/

In future versions, this may be improved to include a POST message and a nice form, as that seems a more natural fit, but as a proof of concept this is ok for now.

An example would be:

enigma/encode/hello/2021-12-19/anz/bnq/

This will result in a page displaying a message consisting of the following parts (without brakcets):

[AAA][BBB][MESSAGE]

where:

• AAA is the indicator key, encrypted using the day indicator and rotor settings.
• BBB is the message key, encrypted using the indicator key and the rotor
  settings of the day.
• MESSAGE is the message, encrypted using the message key and rotor settings of the day.

Decoding

To decode a message, go to:

enigma/decode/<message>/<date>/

This will decrypt the message using the date settings for that day and the indicator and message indicators that were included the message. This message thus needs to include the [AAA] and [BBB] parts.
