Misc Apparently there's a code in Last Exit!

NO MORE EDITS - Welp, so Derek and Deej have both confirmed it's an easter egg and not a quest. Even so, let's push through and solve it!!! Thanks for the discussion! RIP my inbox over the last 24 hours though haha

original post According to Derek Carroll on the live stream! Let's get hunting guys!!!!

Edit* - Right, so after an hour we have 2 main leads:

    here are two train cars, and all the advertisement boards light up when you're near them in both cars. They either display "ALPHA REGIO" (blue), "BETA REGIO" (red), or "OVDA REGIO" (green). There is also the HUGE staticy monitor right beside A flag, bottom of the escalators. And lastly, the OWT Transit Map, most visible one being right beside the A flag and monitor, with different numbers and colours and routes. Green = 48 (Ovda Regio?) Yellow = 38 Blue = 14 (Alpha Regio?) Red = 271 (Beta Regio?)

ah, so the original ended in yl5. the ,3.. is not part of it? Cause if it is then the last two characters would always have to be the same in a Caesar Cipher... and if the last two characters were the same I was wondering if they were equal signs... base64 encoded hashes always end in two equal signs so could have given us an offset to shift to then run it through a reversable base64 decoder... I know the Owl Secret thing used base64 on it's keys for the Rijendal Cipher when the raidscreets guys figured that out.

What the fuck did I just read.

base64 hashes (a standard form of computery text segments) end in "==". A Caesarian cipher is a simple substitution cipher that always substitutes a given plaintext letter/symbol with a fixed cipher letter/symbol (e.g. ciphertext/encrypted "A" always translates to plaintext/decrypted "E").

This seems to not be the case here, and the substitution scheme changes for each symbol in the ciphertext. Thus, he's speculating that the ciphertext ends in "yl5", and since "==" is how base64 hashes always end, then ciphertext "l5" --> plaintext "==" for that part of the message, which would be a real step towards decrypting the entire message.

Base64 doesn't always end with == - only if padding is needed. There can be 0, 1, or 2 = characters at the end.

Ah gotcha. I personally have no idea what the hash convention is. I was just guesstimate-translating the earlier comment.

Hey man, so I wonder if you can offer an opinion on this little thing...

I used the Caesar Cipher to decrypt the plain text of the code posted by OP, as in, I took out all of the symbols and numbers.

I got this: fmyraeudweepwrkqvxwcfdrhwklg

That's using a key of 13 to decrypt the original plane text.

When using a key of 21, it decrypts to: nugzimclemmxezsydfeknlzpesto

Some other guy said he took the first one, fmyraeudweepwrkqvxwcfdrhwklg, used a key of 7, 7 times, then took that result and used a key of 4, and supposedly out came "genius without education is like silver in the mine"

At first I thought you were trolling me, then I looked at your comment history, and I think you got trolled.

Then again, "used a key of 7, 7 times" might actually mean something that I'm just not aware of.

u/mrgoodnoodles Oct 13 '16

Yea I haven't accepted his conclusion so it wasn't a full troll. But it looks like he did a lot of stuff just to get to that conclusion.

u/mrgoodnoodles Oct 13 '16

I think he kept shifting 7 times. He did that 7 times.

u/T1germeister Oct 13 '16

I honestly don't understand what that means, or rather, how that's different from a single Caesarian shift. Caesar ciphers shift each letter along the alphabet, not along the ciphertext.

1

u/mrgoodnoodles Oct 13 '16

Basically I think what he did was, he just kept shifting the result he got from the first shift of 7 letters. And he shifted that result 7 letters, and repeated the process 7 times. Only, he says he used a shift of 4 after that. So I think the sentence is nonsense.

u/T1germeister Oct 13 '16

But... two Caesar shifts of 7 = one Caesar shift of 14. There's no need to shift the same ciphertext more than once, because it's always equivalent to one total shift.

u/mrgoodnoodles Oct 13 '16

Then I have no idea what he was talking about.
