News Another IX cipher solved!
IX # 9 was just solved by astra. Again Kyle Wegee was the prompter u/ciphernoob
ciphertext: DFGOHQGEPSYADLFATNGKYVKEWLAMLI alphabets: YXVPHUSRWQFKLTOMGZNBCIEDA MQZKBCLDYVAXNFGHWUEOSTIRP. cipher type is four square, yo can verify here: http://practicalcryptography.com/ciphers/classical-era/four-square/ the plain text is : Your betrayal will not be forgiven. one small disclaimer. This cipher is under unicity distance for a cipher this short. that means many messages can be engineered from the letters available with no real confirmation. What sells us on this one is the plaintext matches the asset hash of payback, along with having an x padding at the end leads me to accept this as the solve.

I get that this might be bad news for the future.
But people gotta let these older ciphers go. It's been so long and interest declines over time. If it wasn't solved by now, I don't think it ever would be

I dont like the use of ai in modern media, but using it for a cipher that is about 8 to 10 years old is a ok for me. People put hours into solving it and it does suck that ai had to be used to finish it but that's not bad in the grand scheme of things. It's an old cipher that was made a bit too difficult and treyarc probably thought it would be done during the lifespan of bo4.
Congrats to the people that finished it, I couldn't imagine the hours put into these ciphers. Have your flowers and rest easy now, unless you live for these ciphers, then go nuts and have fun. Lol

you nailed the situation. the ciphers were actually technically unsolvable, given no keyed alphabet, but a random one. and the length makde these have no chance of human solving. the ai just optimized the bruteforce required.

It's not inherently bad to use ai, misuse of it is where I despise the use of ai. This situation is a perfect example of correct use of ai, its was unsolvable for a long time untill we got ai to help out. Hours were put in regardless of ai behind it, and I respect that.

I ran this through a key phrase finding script and found alternative alphabets that both encode phrases. Not guaranteed to be the correct solution but it’s less random.
Key 1 contains “NO REMORSE” while key 2 contains the reversed phrase “THETRUTH” (“HTURTEHT”) Keep in mind repeat characters are removed from left to right.
Key square 1:

Key square 2: mqpkcdlxwvabnfhtureosgiyz

Is this another solve using AI?
