9B

[Sofia_Dey_Choudhury]

Maybe trifid cipher? I was so close yet so far when solving it. HELP!!! PLEASE SEND HELP!!

[Sofia_Dey_Choudhury]

I was thinking that cipher as well. It’s not working for me, any advice?
Edit: wdym “Slow Down” Missus Forum, I wrote oNe meSsAgE

I thought I understood the type of cipher used thanks to the case files, but the output is nonsense… is it fair to assume this decrypt is a little more layered than I originally thought?

Definitely fair to think that! Not sure “layers” is the right word, but keep going! Harry

Does the current case file help much with 9b? Because I don’t think that they are that related as you need two slashes per group of five and it doesn’t seem to show a consistent pattern of this…

Also what does the final slash at the end mean?? It doesn’t seem like it’s part of a group

Is it twisted in some way like 8A?

It is twisted in some way like Harry! Harry

I don’t know if Harry will let this go through but here it is anyway:

One of your ideas is what I did to solve it

[CodeKitten]

I don’t think Harry realizes the amount of trouble he has caused for computer programs by putting back slashes in lol

You don’t? How long have you known me? Harry

My first brainwave moment here was to count up the number of each symbol and compare them. This helped me confirm something, but I am unsure on how to proceed from here.

I think it’s a substitution cipher but idk

As someone who has solved 9B I will say that researching something mentioned in 8B really got the ball rolling for me 😉

[The_Pi-thon_Person]

Its no-where near as hard as it appears to be. I cracked it straight away. My advise is to look up madness’s book on cryptography, then head to section 8. Madness’s book on cryptography can be found in BOSS resources… and it is my actual best friend, it is the most informative and useful information on cryptography anywhere. (I don’t think i’ve given anything away here so hopefully Harry will post this comment soon)

Using Word with copy and replace, there is no problem with back slashes. 🙂

[Moses]

On the matter of the backslashes being tricky to work with, in Python I had to make my program accept an input and then run it and copy-paste the cipher into the input each time I ran it, because I couldn’t make it a string. But hey, we got there eventually.

So relatable
