    Funny, I swear Agricola was also a word in a certain language…

    I can’t see a way to translate death of farmer that has 15 letters instead of 14.

    @strider hint: it’s not nominative

    OFFICIAL HINT: The key word for the vigenere is “Agricolae mortem”. Once you have decoded this, you need to decode the affine shift too.

    How do I find which part of the cipher is Vigenere and which is affine shift?

    Stuck on the same thing… just tried doing it layer by layer (Vigenere then affine shift) but it yielded utter nonsense…

    OFFICIAL CLUE: It was encoded first by an affine shift of x -> 7x. Then the result of this was encoded with a vigenere. Hope this solves the problems.

    how would this be written as in key form?

    What does x->7x mean??

    It means if you convert a letter (say, d) into its number equivalent (4), then multiply it by 7 (28) and then find the remainder when it is divided by 26 (2), then convert that number back into a letter (b) then every time it (d) occurs in the plaintext it is represented by that letter you just calculated (b) in the ciphertext.

    Hope this helped!

    Check page 10 of Prof. Graham A. Niblo’s “A beginner’s guide to codebreaking” on this site.
