Hebern cipher machine
=====================

The 1st Problem
-----------------
This problem is not difficult.... Except that it is necessary 
to create a simulator of the Hebern machine (paper or computer). 
To achieve this goal, one must have read carefully the text 
accompanying the problem.

The 2nd problem
-----------
The rotors order and the beginning of the message are known. 
You can try all message keys. In an other hand, it is possible 
to find the fast rotor by isomorphs method. Then no computer
is needed.

The 3rd problem
---------------
You need to calculate IC for each possible rotor. Manual 
calculations are still possible but using computer is easier.

The 4th problem
---------------
The beginning of the message is known but the are many rotors
orders to try. A computer is (almost) needed.

The 5th problem
---------------
Calculate IC seems the right solution ... but perhaps you will
find a short cut?

The 6th problem
---------------
The starting positions of the rotors are known. It is possible
to recover the wiring of the unknown rotor without computer.

The 7th problem
---------------
This problem is the same that W.F. Friedman solved in 1924. 
Are you as gifted as him?
