Can you break Enigma?

Welcome to Anoraks Corner, this is the real stuff

Here are a series of intercept scenarios. In each case if your really brave you can just get the raw intercept. On some if you need some hints to get started you have another option. If you are really stuck and give up, on some there is a complete description of how each scenario was broken.

Scenario 1.

This is a group of intercepts taken in Poland on 15th March 1935.
Previous analysis has shown that the expected wheel order is 132 also that the left hand indicator letter was in the range F to G. What is required is the complete Enigma configuration for that day (rings and six steckers) and a decrypt of the one cipher text quoted.

Scenario 2.

This is a group of intercepts taken in Poland on 26th March 1935.
Previous analysis has shown that the expected wheel order is 132 also that the left hand indicator letter was in the range F to G. What is required is the complete Enigma configuration for that day (rings and six steckers) and a decrypt of the one cipher text quoted.

You should be able to do this now. (One hint, for the ANX search start at GAA on the rings or ZAA on the wheels with the message key on the rings.)

Scenario 3.

This is a group of intercepts taken in Poland on 24th November 1938.
The expected wheel order is 132 also that the left hand ring letter is B. What is required is the complete Enigma configuration for that day (rings and ten steckers) and a decrypt of the one cipher text quoted.

Scenario 4.

This is a group of intercepts taken in Poland on 6th December 1938.
The expected wheel order is 132 also that the left hand ring letter is F. What is required is the complete Enigma configuration for that day (rings and ten steckers) and a decrypt of the one cipher text quoted.

You are on your own with this one!.

Scenario 5.

An intercept on 5th November 1944, probaby German Air Force, with the suspected original German message text derived from another message.

What is required is the complete Enigma configuration for that day (wheel order, rings and ten steckers) and a decrypt of the one cipher text quoted which is on the same base configuration.

If you know it all this is the one for you!.

Scenario 6.

An intercept on 2nd November 1944, of two three part messages probaby German Air Force, with a suspected ending crib derived from another message. (Note: if you tried this before 1st March 2003 there were some errors in the crib and cipher text of part 3, sorry about that, now corrected).
What is required is the complete Enigma configuration for the first message (wheel order, rings and ten steckers) and a decrypt of the second cipher text which is on the same steckers but different wheel order and rings.
