A special National Cipher Challenge for extraordinary times › Forums › Bureau of Security and Signals Intelligence Forum › Challenge 6
Hello Harry,
When are we going to get a hint for challenge 6
You already did (assuming you read the solution to Challenge 5A!)
Harry
@Harry What do you mean? Are you talking about 6A or 6B? [I was talking about 6B. Were you asking about 6A? Harry
PS, Ah, I see, when I said 5A in the hint, I meant 6A. Holiday hat on, sorry! Harry]
Will we get a hint for 6A? I have an idea of how it has been encrypted and made a start but I don’t know where I can go from here
Try decrypting the start and the finish of the cipher text, trusting what you think you know, and see if you spot anything a bit familiar!
Harry
OH thank you
I’m still extremely stuck and I can’t see what challenge 5 is meant to reveal
Apologies, the earlier hint had a typo, and meant to say that Challenge 6A gives a hint for 6B.
How about this for a hint for 6A: try REFLECTING on the cipher text and see if that helps!
Harry
Hi Harry, I am on 6b and I’m stuck. I think it is a transposition cipher, but it doesn’t seem to be working. I have also tried(which I’m pretty sure is not the right cipher) the Vignere Shift cipher, but that doesn’t work either. Any tips?
What did Phil say about it?
thank you
What do you mean by reflecting like looking back or literally reflecting.
@Harry I know the Nazis are using [Edited by Harry] but the Allies are using [and again] but I am unsure if the next message is between the Nazis or the Allies. [Well don’t expect me to tell you! You should be able to work that out using frequency analysis! Harry]
Thank you Harry for the hint for 6A! I thought I’d never get it, now I did it!
Thanks Harry! It was quite obvious when I read through it carefully again! 🙂
