If you are still stuck on Challenge 9B, then you might want to read the brand new BOSS Technical Note 008 on Nihilist ciphers and how to break them. You will find it in the BOSS Library. It is by Madness and is an expanded version of Unit 80 in his fantastic codebreaking book, which you will also find there (BOSS Technical Note 004). Happy reading! Harry
