It seems that my predictions were correct. It isn't because the encryption is 70 years old and we now have supercomputers that we can decipher everything.Dirk Rijmenantshttps://www.blogger.com/profile/03973502421787834920noreply@blogger.comtag:blogger.com,1999:blog-15110991.post-34975737324094639272012-11-06T19:56:48.141+01:002012-11-06T19:56:48.141+01:00Hi Pea,

There are several problems that make it unlikely that the message will be deciphered. First of all, since a pigeon (open tranfert) was used (between HQ and commander inside the UK, the encryption algorithm is most likely a complex one. Secondly, although its source and type of encryption might be found in the archives, it's key will not be found in those archives, as keys never were archived (security breach). Thirdly, to mount a succesfull cryptanalytic attac, you need lots of statistical data (read many messages). In this case, there's only a very short message. If the algorithm used is complex and/or when codebooks were used (no longer available), the chance of getting it deciphered are virtually zero.

One can ask how much propaganda vs thruth is in such messages.<br /><br />However, there's an important detail/difference between the two parties:<br /><br />1. The Germans wrote execution orders themselves in their messages (that's black on white)<br />2. The Germans claimed atrocities by the Allies, and in the same time they tell the receiver to make sure that everyone hears about this (this smells like pure propaganda to scare people to continue to fight)<br /><br />It happens all the time in every conflict. These archives do not show Allied messages that order executions. Having said that, we don't have to pretend that all Allied troops were sweathearts. In the end, they did nuke two cities, but, as they said, only to prevent much more casualties.
