when I first watched the video I thought the gambled messages were simple ciphers where randomness was dominant, but something just never fit... characters had to overlap and connect to make cohesive sentences and it just caused multiple issues for almost every file, so I let the programmer in me to take the helm and use a fresh set of eyes on the cipher... and then it hit me... using statistics and the available data we have we can find the ciphers solution AS A SIMPLE LAYER OF ENCRYPTION!!

So I wrote the following program to use the data an Ai model I developed and generally use found after analysing the text patterns and the results were AMAZING, sadly some letters which could not be read by me nor the Ai model are unknown to me, or at least I'm not sure that they are the correct letters so keep that in mind maybe you can fix them... anyway here is the program and here are the results of running it!

def decipher_text(ciphertext, substitution):
    plaintext = ""
    for char in ciphertext:
        if char in substitution:
            plaintext  = substitution[char]
        else:
            plaintext  = char
    return plaintext

def main():
    substitution = {"K": "H", "R": "O", "V": "S", "W": "T", "O": "L", "H": "E", "D": "A", "N": "K", "G": "D", "F": "C", "L": "I", "B": "E", "S": "P", "Z": "W", "P": "M", "M": "J", "E": "B", "Q": "N", "J": "G", "I": "F", "U": "R"}
    ciphers = ["SKDVH RQH", "FRPSOHWH", "KRVW VKRZV", "QR UHVLVWDQFH", "R HU", "HGLWLQJ", "MRE", "SKDVH WZR", "FRPSOHWH", "VSRUH SODQWHG", "KRVW OHDNHG", "FODWLILHG", "LPPHGLDWH", "SVBFKRORJLFDO", "SUHWXUM", "UHTXLUHG"]
    for item in ciphers:
        plaintext1 = decipher_text(item, substitution)
        print(f"Deciphered Text {ciphers.index(item)}:", plaintext1)


if __name__ == "__main__":
    main()
