Short Description: I replaced a certain letter with newlines

8to16 the 11th of the Ciphers Topic

Just me who solved it.

Scratch is a programming language

You just gotta replace the newlines with a.

I had to. I'm sorry but I had to.

Oh what???? You…but…it…Did you at least give it some time after you updated it?

They submitted this 96 seconds after updating it.

Difficulty Level: 2
Short Description: Don't bruteforce, or I will take all your decoins

Cipher Solvers: Me (@MonkeyBean2)
Solution: (words are separated by null (id 0) characters, I guess these are meant to be spaces, but the encoding was done slightly wrong?)

EVILKUMQUATSWILLBESENTTOYOURLOCATION

Here's it with the null characters replaced with spaces ‘ ’ in case you can't see them or they get filtered out:

EVIL KUMQUATS WILL BE SENT TO YOUR LOCATION

Method: Per byte XOR with key 219
Code (python) (note: text has been encoded as hexadecimal so encodings won't mess up the data when pasting it into a python REPL):

cipher = bytes.fromhex('9e8d9297db908e968a8e9a8f88db8c929797db999edb889e958fdb8f94db82948e89db9794989a8f929495')
result = bytes([c ^ 219 for c in cipher])

see OP: https://scratch.mit.edu/discuss/post/8203958/

Diff: 5 (3 if you know the research tool used to make this ciphertext)
Desc: I always wonder if we'll ever have a plain text, voice file format. I think this might be close. Shame it doesn't encode the pitch as well.

Short Description: I'm worried I'll give it away if I say too much, but what can 13² be written as?

Solution: The number (169)
Method: The sum of each number adds up to 169, which is equal to 13^2.

was this made with ARSS?
i imported the values into audacity but it makes a weird beep noise

They also don't interact directly, ie. you shouldn't xor the cipher and corpus (or anything similar)

If you want more of a challenge, use this corpus: (the cipher and answer should be the same as with the first corpus. Be warned, I haven't tested that this one works)
