+You don't have to figure out the whole key to solve the challenge. Some file formats make better oracles than others.

+Inspired by: http://pthree.org/2012/02/17/ecb-vs-cbc-encryption/
+
+First need to recreate a 54 byte header version of all the files just because it's faster and you don't need to solve for the whole files:
+
+for file in *; do dd if=$file bs=1 count=54 of=$file.small; done
+
+ My solution: write up the helper utils below, piecewise discover what the files are and build out a working header for one of them (and thus the key) until you can examine the encrypted BMP, find the original, then decrypt all the files.
+
+ First try: attempt = 'GIF89'
+ Find the following: key of 62b7de6117
+ And files:
+
+Trying GIF89 against file5.enc.small produes key: 62b7de6117.

+0000   25 50 44 46 2D             %PDF- //PDF
+
+
+But I wanted to do it with an "in the wild" BMP to make it easier to solve. 
+
+
+Nevermind -- word docs are like cheating:
+
+d0 cf 11 e0 a1 b1 1a e1 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 3b 00 03 00 fe ff 09 00 06 00 00 00 00 00 00 00 00 00 00 00 02 00 00 00 9a 00 00 00 00 00 00 00 00 10 00 00 02 00 00 00 01 00 00 00 fe ff ff ff 00 00 00 00 00 00 00 00 80 00 00 00 ff ff ff ff ff ff
+
+That produces the following BMP header: 
+
+0000000: 424d 3e7e 0400 0000 0000 3e00 0000 2800  BM>~......>...(.

+0000020: 0000 007e 0400 c40e 0000 c40e 0000 0000  ...~............
+0000030: c900 0000 0000                           ......
+
+From there, you can either replace, view the image and figure out what it is, or you can just extract the size. That plus the google search: 
+
+https://www.google.com/search?biw=1664&bih=908&tbs=ift%3Abmp%2Cisz%3Aex%2Ciszw%3A1452%2Ciszh%3A1600&tbm=isch&sa=1&q=bmp&oq=bmp
+
+Produces the original unmolested BMP, then you use that to extract the 256 byte key, then decrypt everything.

+## Description
+We've found the source to the Arstotzka spies rendevous server, we must find out their new vault key.
+## Flag
+`We'd all be so much safer if all primes were so free and germane`
+## Solution
+`slurpclient solver.py`
+It's a fucked up, modified implimentation of SRP that requires a user without credentials to authenticate themselves.  So this won't be done til monday, but essentially the field prime -1 is fairly smooth, in this case though it's a schnorr group.  The group is seeded with 9001, so you can use this to find a generator which generates a group of order 4502.  This means that given two different attempts to login, with a generator which i supply as the user index, there will be an easy system of equations, that allow me to derive k * v, where k is already known, once i have this value I can solve for v, then do the servers key derivation algorithm, and send an authenticator as the server, without ever knowing the actual password.
+## Setup
+Attached are two files, one to distribute to players, one to run, this thing is written in python so running it on a beefier machine might be good
