 		I'm back in after a day off - this game moves STUPID fast! So we know it's the enigma encoding?

 		Wow, things have progressed a lot since yesterday. Great, working on the enigma code as well now. Anybody having any luck with it yet?

 		I worked alot with enigma Codes and have some progs.

Without the configuration of Reflector, inner Cylinder, outer Cylinder and the Plugs its not possible to Decode.

Do we have some clues for that?

This is all we have Notromo. Any help would be greatly appreciated!

 		I've tried it but nothing makes a readable word.

Is this the right Input?

 		There are to many configurations.
First the Reflector: B or C
The Rotors have a special Position: Left,Middle,Right so where is 2,4,and 5

It's the only thing we got so far.

One thing I found out is, that when using an enigma encoded message there used to be 2 "keys" or ring positions.
Usually a first operator would select 3 rotors (I,IV,V) and initial position for each rotor (A,K,X), a 3 letter key for the shift inside the rings (A,A,A) and some stecker positions.
A second operator would then select another 3 letter key, write it 2 times (if the second key is ABC, he would take ABCABC) and encrypt it with the enigma (result would look like PGODNY).
The message would then be encoded with the new 3 letter key/shift (A,B,C) and the (with AAA) encoded 6 letter key would be put in front of the (with ABC) encoded message and transmitted.

Thus to decrypt our message one would have to take the first 6 letters of the message, decrypt them with the initial key (A,A,A) which in our case yields SONSOT unfortunately. I then assumed (dindt check yet) that I had made an error in translating the DTMF and it was actually meant to be SONSON, SON being the key for the message and took these ring positions to try and decrypt the message. Unfortunately this did not yield a legible message for me, meaning that either the PM(s?) did not use this technique to encrypt their sentence or we might have to look for other rotor positions...

TLDR: I learned how people encrypted their stuff in WWII but did not figure out the message..

 		Punxtr said earlier he was thinking there were 2 or 3 trigrams or "keys". Nostromo, is having so many repeated letters (ie. III, AAAA) in the encoded message common? It seems to me that wouldn't happen very often. I've been trying all of those combinations myself and I just can't seem to find it.

 		Maybe there is an intermediate decoding step we are missing. This is frustrating! I've even tried it in reverse. Any suggestions? I'm using this one by the way.

 		New email from Dan:

Sorry it took me a while to update you guys. I had to rest so that I won't go irrational and be stressed out.

Bad news is that Genus is missing. He wasn't in the Explosives Testing Bay.

Good news is that we think he is alive. The blast door override was triggered, so I supposed he found it and got his way out. So maybe that's why we lost contact with him. I wonder where he went though?

Bad news is that we still can't reach LAINSY because she's still several floors down and there's still a biohazard lockdown at levels 50 to 54 according to the systems. We were already able to tap into some of the facility systems however some are still until lockdown by LAINSY.

Good news is that we are already able to get in, and we've set camp inside the facility's level 1. Which is why we can already access some of the facility's systems without any problem.

Furthermore, the employees trapped in the living quarters are all safe. Seems like everyone in this facility except for Genus is there and safe. However, they still remain locked in because levels 50 to 54 are still a biohazard zone so getting to them is still a no go. However, I already requested a hazmat team from the company and they should arrive in a few hours. The in-facility hazmat team is locked in at the living quarters so they can't do a thing, because if ever they were in the facility itself, they could have solved the biohazard problem already.

I've also contacted the other BODs and they have cancelled the 48 hour deadline. Looks like I won't be off this case anytime soon.

 		Basically, you have the starting position (SP). You set it to AKX. The you type in another trigram, maybe the ones in the file name, and you'll get an encoded trigram. Set your position to that encoded trigram, and then decode the full message. Make sure you set your steckers and rings right, though. Remember, the rings don't move, nor do the steckers; only the rotors move changing the position.

So, either we have to decode it twice, or three times using the three trigrams I've found... I've ran a bunch:

Code:
UKW B (Reflector): TIC AKX ARL QRY MOQ OTO
UKW C (Reflector): EAE LWU YUU AKX FGG KLJ VRF BFZ


I spent last night actually doing a giant project for uni, though, so I couldn't devote much time to this. That's all of my work.

Edit--Repeated letters don't mean anything. The enigma machine was so complicated for its time, it's why it was so hard to crack. Patterns were hard to find until they found the limitations of the design.

 		The more and more I learn about Enigma machines, the more I think we've got to be missing something...

I agree. There has to be something more. At least they won't get nuked tomorrow. Very Happy

 		Fearing that we've hit a wall (and we were doing so well!!!), I asked for a bone -- "we're stuck, we've got to be missing something, did you find anything that Genus may have left behind?" kind of request. Got a reply:

Maybe we're missing that's right in our faces and don't see it? I'll try to check back with the programmer who figured out this enigma code and see if he can provide any further help.

And yes, the deadline was cancelled they required me to set foot inside the facility, of which I am already right now. So yes, progress is good.

We MUST be missing something. Bang Head

 		Another email from Dan. This looks to be helpful.

I've got to talk to the programmer and he said something that might be of help.

He says, they are two types of enigma transmission. One is a standard enigma transmission, of which can be decoded using a code book so that one will know what particular settings for the rotors, initial position, and plug board. However, the other type of enigma transmission was used after the WWII and sends in the enigma configuration along with the encoded messages. Usually the settings are sent before the coded message is sent, but they are sent immediately after the other without any gaps to make them seem like an entire coded message. This might have been insecure, however, it was used after the WWII so most people won't really know what it is if ever they have the chance to intercept a transmission. Because, it can be anything of any kind of encryption. So that's what I was able to get from him.

I hope that helps.
