Station X,
May 21, 1940
Dear friends,
Yesterday you accomplished an incredible feat:
you have successfully reconstructed the Enigma
daily key manually from methods of Knox and
Herivel, well done! I know you are exhausted, but
you must repeat your feat.
You're not starting from scratch this time around.
The yesterday's decryption we confirmed the use
of the "CILLIES" type messages keys: HIT, LER, CIL,
LIE, DIE, UHR,
ASD, QWE,…
On the other hand the CSKO key rules are used as
well the rule which involves that a rotor
necessarily occupies a different place the day
after. Yesterday the Walzenlage was V-I-III which
we allows you to eliminate a lot of possibilities at
once.
Good luck!
