Koordinaterne i denne serie af cacher er ikke koordinaterne på selve cacheboksen, men på en bekvem parkeringsplads i nærheden. For at finde cachen skal man dechifrere en kodet meddelelse hvor den resulterende tekst er på engelsk. Det kan også blive nødvendigt at søge visse informationer på internettet. Da disse informationer næsten udelukkende findes på engelsk, så er man nødt til at kunne læse og forstå engelsk. Resten af cachebeskrivelsen er derfor på engelsk.
This is a Mystery/Puzzle cache. The coordinates of this cache are not the coordinates of the cachebox, but they will lead you to a convenient parking area.
The cachebox is a 2 liter container hidden in “Sandbjerg Østerskov”. It contains a logbook, a pencil, a FFC and some trading items.
Around year 1549, Blaise de Vigenère invented a powerful new cipher. It remained largely neglected for the next couple of centuries, but was later to become known as le chiffre indéchiffrable. The advantage of the cipher was that the sender and the receiver only had to agree on a common key to send secret messages to each other. The key was a relatively short word or sentence that was easy to remember without writing it down. The cipher was broken in 1854 by Charles Babbage (who did not publish his discoveries) and in 1863 by Friedrich William Kasiski.
The ciphertext below is enciphered using this method and the Puzzle is to decipher it with the key in order to get the plaintext leading to the cache. The Mystery is how to find the key.
The logbook contains keys to other caches in the CCC-series. I have decided to make it easier for you: If you can decipher this cache, you can now decipher the text here to obtain the keys without going to the cachesite first.
Thanks to Simon Singh for inspiring this series of caches.
