There’s a suit bag in that shack. Could this guy be G-Man?
NEWS: 3914 is a possible value for d as well - too much of a coincidence imo… hoping a coder wakes up soon and can do something with this
EDIT: Completely stuck now, if anyone has experience of modulus operations then work out the qinv[/SIZE] value from the wiki, it seems like it should be really simple maths, but I don’t know the right technique so I’m basically facing ? hours of trial and error to do it - I tried running the less efficient way method by hand (and calculator) and ended up with unusably large numbers because of the c^3914 
EDIT 2 - Found a java applet which might help: https://www.holowczak.com/rsademo/
plugging in some numbers now
EDIT3!! - java applet sucks for what I’m trying to do, asking around in IRC to try and get some help with calculating this
Um, 27 is not prime. Or at least it wasn’t last time I checked.
And modulus is a division remainder. So 10 mod 3 = 1 for example.
23 and 37 are prime though…which is what I typed. And yeah I worked out the basic modulus operations, but a little confused by indices and multiplication within them
Oh, well if I could actually read the numbers it would help, wouldn’t it. 
I had to go back and check I hadn’t made a typo 
I dont know if this helps much, but I remember seeing “271” written in blood on the floor next to a dead scientist.
I dont remember what chapter it was, so…
It was 247, and it’s the order of the portals you have to jump into in Lambda Core. Not related to this ARG.
Not sure if this is related to the ARG.
Each console at the beginning of QE has the following three numbers in random order:
976 512 348
Of any use to the discussion ?

Hey I was going to test what you suggested in matlab real quick just now but there is a problem.
e and phi(n) need to be coprime. If e = 9, and phi(n) = (23-1)(37-1) = (792), then both e (9,) and phi(n) (792,) have a common factor of 3, so they’re not coprime.
I don’t know for sure but considering how ubiquitous pigpen code is I’m thinking you guys might be over analysing some of this.
Well, we already solved the pigpen cipher and we’re not questioning that. The Cascade cipher is something else that we found.
saph, that’s using the standard version - if you use the version with the lambda symbol (PKCS#1) then there’s no such issue - I’ve just finished crunching all the original cypher text through a spreadsheet, will upload onto google docs for people to have a look (2mins I hope)
EDIT: Google doc …struggling to get modulus formulae working in google docs so have just uploaded the raw numbers from my spreadsheet - if someone wants to verify using the chinese remainder algorithm from (RSA article on wiki) then please do - I already found one error and corrected it.
Interesting result is the number 93599 in the third block of ciphertext which comes out as a 0 in decryption - might have been a fluke, but it’s a number which would have revealed the two factors used in the encryption
So, when you decrypted it, what did you get? More nonsense?
Edit: I see, it was nothing.
Pyro, I have no prior knowledge of making text into numerical data, but I’m 99.999999% sure that this is the correct form of encryption - I’m sure it’s not a coincidence that 3914 is one a possible d value (1 in 400 chance) when the other two figures are used for e and n
But as for converting numbers into text and for finding out the ‘message padding’ algorithm as mentioned on RSA wiki, I have no idea
Well as long as it works.
But what to do with whatever it is that you got?
Yeah it looks like more nonsense (which if it’s made to have multiple cypher passes it should.) While it’s interesting, it’s not enough to convince me that we’re on the right track.
Really this is what I’m thinking: Many of the times we find the pizza box throughout the game chapters, it’s next to the biodome symbol (the latin DNA thing.) I think these are meant to be hints to look in the QE chapter. Everything we’ve found has been there already.
I’m only really happy with the A and C codes. The solutions were very direct, always saying “This is the code” there was nothing iffy about it. The tic-tac-toe possible solution I’m not happy with, and while I am very confident that the cafeteria picture overlay (0581) is relevant, we’re missing something because we didn’t get the message we got with the others (ie, “This is the X code:”) The Tic Tac Toe thing probably converts to something like “Code B Cafeteria,” but that’s just my guess.
Judging from the Dr Bottomly message, I’m willing to bet we can decipher (not decrypt) that into a message, which has a code in it. If it was encrypted we wouldn’t see the very non-random distribution of numbers 0-9 in it. Proper encryption yields a very flat character frequency, coding does not. And that message has a very biased distribution of numbers.
EDIT:
Here’s what I mean. This is the number frequency from the Bottomly message. The blue line is the actual frequency, the green line is that of a random sequence of equal length. Anything encrypted should look just like the green line. Anything encoded would not.

Yeah, sounds about right. Which means we’re back to square one, again.
Edit: and yeah, the frequency is a very good point; we were discussing that earlier.
Hey, been looking at all your progress so far, and thought I’d pitch something: https://i.imgur.com/dixsE.png
There’s quite a few of these signs dotted about. I found it right at the end of Q.E, when the scientists let you out. Just an easter egg though. The Dr. Horn Plaque moves as well when you go outside; probably a bug.
The Plaque moves? What do you mean?
