I’ve constructed a weak cipher and made a sample implementation of it, and now I have a challenge for you: Find the key with which this file has been enciphered. You can find the characters supported by the cipher in this file.

To help you out a bit you’ll also get the sample program which can encipher and decipher text using a specified key. Please note that it’s not intended to reverse engineer the program.

If no-one has reported progress (or success) after one week I’ll post the source code to the librarary, and if there’s still no progress after yet another week I’ll also post the non-enciphered version of the text. Then I’ll wait a month or so untill I post the answer.

I intend to release the library and sample application later, but for now you are not allowed to modify or redistribute them.

Good luck!
