Jekylman: Remove Q's, and then anagramize among the word islands

...and that's as far as I got


You were headed in the wrong direction.  It's a simple 13 column, 11 row transposition cipher with the Q's acting as nulls:

It's just another JPG.
If you do what DuudeStanky said:

Search for hex FF D8 FF E0. Search twice.
The second image starts at the second set of those bytes. Select to the end of the file, copy, paste into a new file and save as comp4jpg

GoSlash27: The 5 letter grouping is a giveaway that it's a transposition cypher. The groups must be stacked and read downwards by columns. With 5 columns and no available key, there are 5! (120) possible orders to read them in. Perhaps looking at the original release for a 5 letter word will make it easy.
 After that, it's probably a monoalphabetic substitution cypher. I'll have to print it out and play with it today, but I'm not hopeful.


Wrong, wrong, wrong.

Ignore the 5 letter grouping.  The grouping has nothing to do with the encryption method, period.  Ciphertext is generally placed into groups like that to make it easier for the people responsible for sending and receiving them to work with them.  Historically, it allowed radio operators to "pause" a brief second to read the next group before sending it, which you have to do when sending random letters and/or numbers instead of intelligible plaintext.  That goes for typing a message into a teletype, sending it via Morse code, or reading it out on voice.

secured was the final answer for me


The funny thing is that I'm not sure if you're supposed to just guess and enter the word or if there's actually some encoded clue included in the standard's page.


paleryder69
it is obvious they embedded some kind of whitespace code in the javascript section of the html 5k lines worth...

Then again, 100s of lines of whitespace are also typical for websites using JSPs because *everything* between JSP tags will end up in the HTML and that includes the whitespace like line-breaks and tabs added to separate the Java from the HTML blocks.
So if you write bad JSPs with lots of Java code and want to keep the source JSP readable, you'll end up with tons of empty lines and strange line breaks in the HTML if you aren't paying special attention to avoiding it (and who really cares how the source of a generated webpage is formatted).
A typical sign for a JSP-backed website (which the standard's site shows) is that there are several empty lines before the first HTML or even the DOCTYPE.
That's where IDEs like Eclipse will insert the import-directives for all the classes used by the embedded Java code.

Head_Shot: Sometimes my fellow farkers impress the hell out of me.

This one was fairly easy.  Don't be too impressed.

The columns weren't shuffled via a key, which would have made it more difficult, and the total length was the factor of two primes.  A real message wouldn't be exactly that length, so you'd have to jigger the column lengths until it came out right.

netweavr: A computer would deserve to be called intelligent if it could deceive a human into believing that it was human www.metro.co.uk/turing?


That's it.

It actually stymied me a bit because I'm not used to working with transposition ciphers, but two things clued me in, both from  Theaetetus:

You may be on to something. If you pull out the Q's, the frequency distribution is exactly what you'd expect for English.

As an additional clue, minus those Qs, it's 123 characters, which is 41*3.


Pulling the Q's gives the right frequency distribution for English, but Theaetetus made the mistake of pulling them when checking the factors.  When I saw the factor thing, combined with the distribution, it made me think "TRANSPOSITION!".
