I have a collection of linked Ada programs produced in 2007 by a guy called Joachim Schueth for the decryption of German high command WW2 (AKA Lorenz, after the name of the company who manufactured the machines) messages. The programs were written to win a competition, described on http://tnmoc.org.uk/cipher5.htm. Unfortunately, the encoding modes for messages described there have some inaccuracies e.g. the ITA2 code for " is documented as +. This means that his program either converts the + (when in Figures mode) in the supplied messages to " and thence to the correct ITA2 Bit Code of MSSSM (10001 in binary) or directly to the correct ITA2 bit Code. can any bode tell me what's happening on this point?
Joachim has documented his programs minimally on http://www.schlaupelz.de/SZ42/SZ42_software.html. Unfortunately, Joachim does not seem to be contactable. I can be contacted on johndotaarondotroseatgmail.com in order to send the programs by email.
