    OFFICIAL CLUE: Follow the standard cipher breaking techniques you have been using so far. If you have broken all the ciphers up until now then you can solve this one too.

    @shredha Take a break, you won’t solve anything if you can barely type! If you stare at a cipher text too long you spot ‘patterns’ which aren’t actually there.

    OFFICIAL CLUE: The keyword is different, but the cipher is the same type as last week. Calculate the ioc to see the keyword length, then do frequency analysis on each bit in turn to figure out the keyword/caesar shift.

    Please could the next hint be to do with the keyword because that’s what we are the furthest away from figuring out.

    @Ushie_Baby786 IOC is the index of coincidence, a quick google should tell you what this is, how to calculate it, and why it’s useful!
