Enigma is fatally flawed in its current design, AFAIK. Due to the nature of
how its rotors operate, it can't encrypt a letter to itself, introducing a
statistical bias into the ciphertext.
Enigma would need to be modified so all letters have equal probabilities.
Someone who knows the intricacies of these rotor machines better than me
might know what's involved.
