Hi all,
 
I recently finished my Doppekastenschluessel-Hex project,
which is a simplified version of the original German WWII
cipher, with hex notation.
 
For more details check my previous thread 'Seriation'
 
Your task is to crack the provided message, which uses
only one key for encryption, instead of two (default)
or more.
 
The message:
 
75 A2 85 D1 84 59 85 2D 25 CB 85 1C 24 70 27 6C
C5 3C 65 2E 87 6C 8E E7 89 E9 C9 3E 8E 7D 8E D6
 
Please note: The message is written as normal text and
not like plaintext messages from the old days and with
padding applied.

 
Perhaps we need a larger amount of ciphertext?

That would make cryptanalysis easier, right?

BTW. For drawing the winners, should they been drawn from
a random pool of entries, or by first come first serve?
