I'm adding a copy of the EWCG newsletter here. You may get a link if you are registered as a contact on the EWCG website. For the November/December newsletter I plan to have messages in the following formats:
1. Werhmacht/Luftwaffe 3-wheel no Kenngruppen
2. Wehrmacht/Luftwaffe 3-wheel with Kenngruppen
3. M4 Kriegsmarine in advanced format
4. M4 Kriegsmarine Offizier to Offizier in advanced format
5. M4 Kurzsignale message (Short message format)
6. Wetterkurzsignal (Short weather message)
You'll see I'm also looking for pictures of actual Enigma machines, Replicas of Enigma machines, Simulators (like my S&T Geotronics) of Enigmas, codebooks, or any other historically significant picture of the Enigma or people or places (BP as an example). You must have permission to share it, and you must grant permission for me to publish it.
I'm open to adding a message encrypted using the RHV.
I will also be working on Code books for TRITON, HYDRA, THETIS, and the bigram tables for 2019. These will be available on the EWCG website before years end.
To help people decipher my messages, I will answer the messages with their same respective key so the inner and outer settings do not have to be changed between messages and answer..You only have to find out the start position.
So for message #1....with key from Bruce's keys Sept 3rd 1944 (I do use a Kenngruppen though)
As far as Weather messages are concerned, I am not a big fan of those. From what I could gather, it seems that in Irland, the weather was constant, rather nice, windy but calm sea. I find it wierd however that box 10 indicates light snow falls (I have an N as decrypted letter) while box 18 gives a temperature of 18 degrees (K as decrypted letter). But then again, I could have made a mistake and I am not very talented in meteorology.
LOL! Not to worry the weather messages. I just got a very clear copy of the WKS book from the NSA National Cryptologic Museum and spent several long nights doing translations. Turns out, the weather instructions on the website are for version 2 and the version I got from NSA and what you see online is version 3! Guess what? As of version 3 the header starts with QQ not WW. The other really BIG surprise was as of version 3, it is all M4, M3 is gone and the machine settings are based on the Schlusseltafeln M Allgemein (standard daily key for the radio net)! There is a separate keysheet for settings the rotors prior to encryption. And they are 4 character settings. I will have a new book uploaded in the DropBox and the new keysheets. I haven't decided how to handle the current setup on the web page but it will have to be changed. Probably some time when I can't sleep and I can work on it overnight.
Not sure how you got an 'N' in column 10, should be a 'H'. Ireland is correct. 18C is correct.
I did not have the time to try the short messages yet.
I'd like to ask about the numbers you used in the above message.
The decoded Kennengruppen stripped of the dummy letters are (according to me) AFF and NAV Their respective numbers are 619 (Triton) and 615 (RHV)
this RHV Procedure group made me, at first, think it was and RHV message....I know that the key characteristic group should have been between 201 and 250 to also be RHV.
So...maybe my question is how do you choose between column Schlussel M and RHV in the Allotement List My understanding was that Schlussel M was for regular use and RHV was to indicate that RHV procedure was to be used.
The answer is this, only the Schlusselkenngruppe defines what radio net to use. If you look at the Zuteilungliste, the acceptable range for “all users” is very large for the Verfahrenkenngruppe. So, it could be from any radio net. But to verify what cipher (Schlüssel) key is in use, you look to the first group (Schlüsselkenngruppen). The Verfahrenkenngruppe is chosen to create the Message key and you use a much bigger pool of values (up to 17,576) to build it.
EDIT: I went back and re-read your message. You are correct, my choice for the Verfahrenkengruppe was incorrect and made my message void. The correct range was 1-400 and I chose a number outside that range. But my point above is still valid, as the intent is to have as large a pool of values for the second group as possible. But, I should have been more careful as to my choice for second group.
