Hebern: 3rd Problem

Washington May 6, 1924

Dear Laurence,

The next challenge is more complex.

You don't know the rotor wiring. On the other
hand, you know the plaintext of an encrypted
message. You need to find the plain of a second
message.

The Lampboard and keyboard are equal to the
identity permutation.

Good luck !
