Trying to decode a cipher but need assistance.

In this cipher previously posted by DrJacoby, you're given 2 hints which are both an audio file and an image. The audio file (when viewed in a spectrogram) gives you "-s 7 -m 153". Because of the name of the file and how that looks, you can see they're command parameters for this crypter.py file. This means your final command will look something like this "python3 .\crypter.py -i .\decrypt_msg.txt -o output.txt -c X -s 7 -m 153". That X is where this last image comes in. I believe both these hints are command parameters where the audio file tells you the shift and mode to use, whereas, the image file tells you what cipher to use. please look at the image and let me know what you get from it. So far I have established 2, 3, 5 and 6 are all wonky and have rings on them, giving you the new number sequence 2, 3, 4, 1. All help is appreciated!

Damn, I have no idea lmfao. I'll try to give it some thoughts but I'm not good at puzzles like this. They're not practical. What does the -c switch even do? Also is it just me or do the numbers "rotate right", so to speak?

Yeah you are right they do seem to be rotating right the -c picks the type of cipher you're doing You can see all the options in the code

functions = {
                    1: cipher.caesar_decoded,
                    2: cipher.caesar_encoded,
                    3: cipher.xor_execute,
                    4: cipher.base64_decoded,
                    5: cipher.base64_encoded,
                    6: cipher.reverse
                }

functions = {
                    1: cipher.caesar_decoded,
                    2: cipher.caesar_encoded,
                    3: cipher.xor_execute,
                    4: cipher.base64_decoded,
                    5: cipher.base64_encoded,
                    6: cipher.reverse
                }

What's strange is that the numbers in that image that are altered don't go above 6 and then the command also only allows up to the number 6 This is why I believe the image is telling you what cipher to use

w33t•2y ago

Part of me wants to say 4 because 4 is the only "right" one so it'd be right haaaaaahahahaaa idfk, I'm bad at this.

James Charles•2y ago

Lmao, it's such a strange cipher

w33t•2y ago

Why don't you just try each one and see what happens lol.

James Charles•2y ago

I have indeed done that My theory is that our tutor has used multiple

w33t•2y ago

ohhhhh

James Charles•2y ago

If you look at the original code being

It looks like a very strange cipher

w33t•2y ago

That's why I'm not a big fan of these, they aren't too practical unless you're doing some really specific type of work.

James Charles•2y ago

Having lots of ws It just looks weird I'll update you on anything I find I tried to reverse engineer it by creating my own cipher This is my Cipher

Looks pretty similar I did that by following the numbers on the 12days.jpg so now I'll do that but with the original cipher backwards @weet i did it I'll give you the full process when Jacob figures it out

DrJacob•2y ago

I did it whoop

Muta•2y ago

At this point i better shit myself with AES documentation and crack TLS and then be known as a man who hacked internet litterally, than doing these, ig some of them proves some kind of concept? But most true ones uses math and algorithms so you better learn those
