The standard CryptoQuip, as it appears in the comics, is a simple substitution cypher where one part of the solution is provided, and it's up to the player to figure out the rest from the provided cyphertext and the clue. It's a fun little puzzle to play, but that doesn't stop a more analytical approach.
This project is about a few different attacks on solving the general CryptoQuip puzzle in as short a time as possible. There are other versions of this same attack, and there are several different attack schemes. This just happens to be the fastest we've found.
At this time we have a limited web server in the server namespace, and it can
handle a few requests. To start it, simply:
$ lein run weband then hit:
GET localhost:8080/info
and you'll see the hello output:
{
"app": "cryptoquip solver",
"code": "unknown commit",
"hello?": "World!"
}The goal is to have the uberjars include the git hash, and then have this in the response. I've got the code for extracting it, I just need to work in the code for renaming the uberjar.
To see the benchmark code, hit:
GET localhost:8080/benchmark
and you'll see the cyphertext, the clue, and the plaintext:
{
"clue": { "b": "t" },
"cyphertext": "fict o ncc bivteclnbklzn o lcpji ukl pt vzglcddp",
"plaintext": "when i see thunderstorms i reach for an umbrella"
}The log file has all the details about what's being called, etc.
More endpoints to be added soon.
We have added a simply jQuery/Bootstrap front-end to the solver so that it can be easily run by anyone simply going to localhost:8080/ on the main site. It looks something like this:
You can simply enter your cyphertext, and then enter your key, and hit Solve!, and if there's a solution, it will be presented. Simple.
Right now, there are tests that run a standard quip, and the main also runs
a standard quip - directing the output to log/cq.log for debugging and
monitoring purposes. Simply:
$ lein run blockand then the log will have something like:
