As suggested in the comments on the Telegraph article, it would would seem likely that this message was encrypted with a one-time pad, making it essentially unbreakable. Unless the key is found in some MoD vault (and released to the public).
- andyjohnson0 14y agoProbably correct. Another option is that the message was produced using a cipher machine, which were in use by the allied forces at that time. If a machine and records of the pre-arranged keys still exist then decryption might be possible.
- tomjen3 14y agoIf we can find records of how that machine worked, then we should be able to build a program to break the encryption.
