The Enigma Room

[HM.Medico]

I created a thread a fair while ago (about 10 months ago or so) on the same topic, problem was it never kicked off. Anyway, I found an Enigma machine on the internets and thought I might share. I decided to screw around and re-download the enigma machine from here and have some fun with you guys. Let's play a game. Rules;

1. You must give your starting reel. (for example, the one used in my message was AAA)
2. If you change your reflectors and such, you must give details (just provide all the info)
3. If you bridge circuits, tell us which ones you bridged
4. Have fun

My message

Starting reel: AAA
No reflectors or altered reels
No circuits bridged

Hope i did this right..

use reel ZAB

message is as follows...

Wicked. I was thinking of doing something like this. Lets up the ante for anyone interested.

I used the Enigma Codebook Generator program to create a code book for April of 07.

Download it here. Its a notepad file.

And read this to figure out how to operate the machine. http://users.telenet.be/d.rijmenants/en/enigmahelp.htm

I used the Kriegsmarine 4 rotor reflector. The code adds to the chore of decoding significantly.

Now my message.

Following standard procedure for enigma operators there are two key letter groups at the beginning which are important, those being the 4 starting reel letters. After you set up your Enigma machine for today you take the first set of 4 letters and use them as your starting reel. Then you decode the second 4 letter group. The decoded letters form the starting reel for the rest of the message. Complicated enough for you?

The operators would select the random starting reel so that it was more random. With these two starting reels you effectively code the code.

Here goes.

not sure i understand the plugboard...

in your code book it says for the 27th... for the plugboard settings

BN CW DV ES FI HO JY KU LR PQ

does this mean we should connect B to N, then C to W, then D to V etc etc?

everything makes sense up to that point.

HA! got it! nice work on the codes P_Funk!

No problem.

Glad you got it to work. Now give us a message of your own. You can use the same codebook. And when it hits May, if we're all still doing this, I'll make another one.

[GoldenRivet]

LOL Well here you go... although i think you read my mind hahaha

EDIT. I've created and uploaded Enigma Codebooks for the remainder of 2007 on my filefront page. I also uploaded the Enigma Simulator and the Codebook Generator.

haha i was just 10 minutes ago saying to myself "man this is so cool.... im such a nerd"

P funk, i'm confused, how do I know which tag to use on your codebook?

do I use 27 and the Beta reflector due to it being the 27th today?

I understand how to set everything up, just not sure on which tag to use from your codebook

You use the 27th yes. Its a monthly code book. The column titled 'Tag' is the day.

[rb4door]

yay I got it



The scarey part is how complicated the setup for the rotors / reflectors and bridged circuits is. Just one incorrect setting on anything and you are going to get nothing at all. I'm assuming thats a "realistic" setup P funk?

Your coded reel settings for the main message seem to be in line with what the manual says they actually did in real life.

[P_Funk]

Yes when I found all this a few months ago I did some shallow research into the official procedures for encoding messages. But the way we're doing this is far from the official way. There were actually manuals that explained how to word messages and how to abbreviate certain non-alphabetical symbols.

But I do find this fun enough for the moment.

[P_Funk]

Okay just a silly little one here.

hmmm, do you do any troubleshooting for the Enigma? :p


I just started decoding Goldenrivet's message - I got this:

"WHY NOT GO AHEAD AND GPVZ JNKX ZRTZ OTHD GQLR UBFR WWBY XGTU VQES SAJX LNAU KQXJ IDPS ECTU DXIM THRM JKNJ RDFA KMPT QOQW OLFJ UAPQ HZES JLJT UJYN HTXY DDZB EDTI XRID QXEE VDWM DLCE "


Edit: disregard,tried again and decipehered it perfectly - no idea what went wrong there.....
