Backdoor
Summary
After discovering that V called someone at the Academy's Crypto Department, Caine heads over to Crypto to investigate. He runs into his friend Neville Clark, who is talkative, if obfuscating. The Cube Hunters entice Nev into sharing more information by giving him a puzzle, designed by jbd, to solve. Nev takes the bait, and gives us a backdoor that leads to a gridded file system.
Dragging the commands onto the grid to create various configurations yields a series of log snippets. Some of the logs resemble the Perplex City Errorlogs that were found before the puzzle cards were released.
The interface can be accessed at the following URL:
http://events.perplexcity.com/gateway/commandinterface/index.html
As of 17:08, 3 July 2006 (PDT), the puzzle is still being worked on. Join us in #syzygy, or see the discussion on the Talk page or at Unforums.
Commands
Through the combined work of jalapenodude, pelrun, and jbd, #syzygy has determined that the commands appear to work as follows.
The program pointer starts in upper left corner. It moves through the grid one space at a time, as determined by the command in that space.
Generally, the pointer moves in the following directions when it encounters each command. Some exceptions may occur.
popen - east pread - west mount - se pwrite - e switch - se (Are you sure, goes NE on config 5 below?) copy - s flush - s
All of these can go funny in certain circumstances, especially when next to an edge where the next command would normally jump off the grid.
rotate does something different depending on where it is executed, but also (sometimes?) where it comes from. Here are some directions that occur:
e e e e s s ne n n s e n ne n s ne n ne n s ne n ne n n
However, it is possible for r3c5 to go north if entered from the west, for example.
The same goes for zone:
e e e w s s w w n n e e e n w n w w n n n w w n n
End ends execution whenever it gets hit on a specific error message. It is very good for testing where the code is going. Cache seems to only work as an end point. Run can go anywhere that the program pointer isn't reaching.
A configuration is a set of commands placed on the grid so that the grid is valid and a log file is retrieved. The command path is the actual path that the pointer takes through the grid configuration. Different configurations may break down into the same command path.
Configurations and command paths start with ZO-MO, and usually end with either CACHE or FLUSH.
Full Command Path List
The first two numbers are the resulting configuration, the letter after is the variation, and the string is the command path, with each instruction cut to two letters in length. The list is alphabetized based on operation name, as a reference service. Please be sure to also place them above with their respective results, and to sort them in properly when added.

Command/File Mapping
The number of times the zone, switch, and rotate commands appears in a command path determines which file is displayed.

Approached the Master today about begining on an updated and revised edition. V. pleased to discover he considers the idea warmly. He actually said, 'My ideas are in good hands with you, and you will of course receive full credit for the work.' Somehow I expected more of a struggle. V. gracious indeed. He's not quite the glory-hog SOME people have made him out to be, I guess.

To: 55321801 FROM: MANSOOR H. Kiteway's programs are disrupting the entire department. Breeding hostility and distrust among amicable colleagues. The man doesn't belong here anymore, why can't he keep his damned pet projects in his own office? Crypto is mine now, not his. Well, here are the metrics to show he's not minding his own business. Number of times Kiteway has visited dept. offices this year: 78 And in 268: 129 And in 267: 23 Dept. suspicion level on the Howe-Panntonin Index: 8.8 And in 268: 7.3 And in 267: 4.5 Suspect the man has his own agenda and isn't sharing with the proper channels, for example me and you. Suspect he is subverting the time and resources of my faculty without consulting me ahead of time. Behaving as though he can't trust his own senior fellows. Ridiculous. How long must we put up with this childish rigmarole?

Historical Cryptographers
Some of the names mentioned in the logs share the names of historic cryptographers and mathematicians.
- Bazeries
- French military cryptographer, the 'pragmatic man of cryptology'. Famous for breaking the French 'Great Cipher' created in the 17th century.
- Porta
- Giovanni Battista Porta, Italian cryptographer and inventor of the Della Porta cipher - a polyalphabetic cipher with keyword.
- Ashford
- the name of the village in Kent where John Wallis, 17th century mathematician, was born. He wrote among other things, about the quadrature of curves, logic, theology and cryptography.
- Carrick
- the name of a Windows-based encryption application, designed by cryptographer Bruce Schneier.
