Dear Mr Hilton,
Here is an encrypted
message thanks to the Tunny machine.
We have restored the internal key through other messages.
We have also reconstructed the table for coding the message
key.
In conclusion it is a
good exercise for you. You can decrypt
it manually without using the Tunny machine. To help you, I
give you the current version of our report
on Tunny.
Good luck !
William Thomas Tutte
