Code Issues Releases Wiki Activity

Finally removed the "bug" with the bad encryption; It was a known anomaly in the historical enigma machine that I oversaw. So I added this "historical bug" as a feature to the enigma. Thanks to the author of the java script version of the enigma machine for the hint :)
