To Deputy Director
John Tiltman,
Sir,
I adapted the T52
cipher machine manual to create for the
T52e one.
Thanks to it and
thanks to our previous works about this
machine, I managed to encrypt a message. This exercise can be
used by our teams trying to decipher encrypted messages with
this machine.
Best Regards,
Michael Crum.
=========== Example
==========
I have encrypted the
following message with this key:
Inner Key: 3, 1, II, V, 9, 7, I, IV, 5, III
External Key: 19, 27,
28, 21, 39, 20, 32, 4, 47, 40
(From "K" wheel to "A" wheel)
