Enigma/Sample Messages

This page includes various examples of real, contemporary Enigma messages (collected from several sources, acknowledged below). You can decrypt these with the Enigma Simulator app (see the User Guide).

The plain text of the messages is of course in the German language, and may include abbreviations and conventions such as "X" for a space, "J" for a quotation mark or "Q" for the two characters "CH", so further interpretation and translation will be needed to produce an understandable message in English. The decrypts and translations are on another page if you would like to check your results.

Acknowledgements

Thanks to Ralph Erskine for discovering the 1930 example message, published by Frode Weierud. Turing's Treatise on the Enigma was preserved in the US National Security Agency archives and released to the public in 1996; a version transcribed by Ralph Erskine, Philip Marks and Frode Weierud is available. The Operation Barbarossa message was published by Geoff Sullivan and Frode Weierud as part of their project to discover the keys for many unbroken Enigma messages. The machine settings for the U-264 message were discovered as part of Stefan Krah's M4 Message Breaking Project. The Scharnhorst message was also decrypted as part of the M4 Project.
