I Decrypted an Enigma Message Transmitted by Radio

#cryptology, #cryptography, #cryptanalysis On Saturday the 23rd July 2022, the Maritime Radio Historical Society (MRHS) and the Cipher History Museum sent an Enigma-encrypted radio transmission via the KPH stations. I was able to receive the message and decrypt it using CrypTool 2. Message was sent via Morse (CW) frequencies and radioteletype (RTTY) frequencies. In this video, I explain how I received the message using KiwiSDR and how the Morse decoding in KiwiSDR and the decryption process in CrypTool 2 worked. I thank Tom Perera from the cryptocollectors group for providing the playbacked parts of the original audio recording of the transmission. I recorded the wrong audio device, thus, I only had the video recording of what I did. - For the MRHS, please go to: - For the Cipher History Museum go to: - For KiwiSDR go to: I received and decoded the following message using KiwiSDR: FQ CQ DE KP
