By now I’m sure you’re all thoroughly sick of the way I heap superlatives and laurel wreaths onto Tony Gaffney’s hair-bestrewn head every time he cracks yet another of Bellaso’s ciphers… and now he’s broken two more, lifting his tally for the 1564 set of challenge ciphers to 6 out of 7. Though Tony dearly wants to make it 7/7, Bellaso’s remaining 1564 cipher appears to be an awkward one, a real Holmesian three-pipe problem… so let’s keep our fingers crossed Tony can make it a clean sweep. 🙂

Anyway, as compared to #7’s tortuous digrams, #3 turned out to be relatively easy: it involved five rotating reciprocal alphabets (Bellaso’s favourite starting point), with the confounding trick being that the first letter of each group is basically random, and indicates which one of the five rotated alphabets to use (by using the index of the letter within the cipher alphabet). There are asterisks marked at the two places (in lines 1 and 3) where this fails to quite work, but the basic idea seems completely solid.

The (possibly meaningless?) keyword here is “QUA(C)EHTBS”, yielding a cleartext like this:-

La sumita de monti se conserva perche l’acque ot neve
che sopra de esi speso cadono in si contengono le esalationi
et vageri terestri asesi ne l’aria ox virtu solare et cosi
la tgu che per le piogie scorgzoso de monti xe piogie et nevi
la repone sopra deti monti.

And so we move onto Bellaso’s 1564 challenge cipher #4, which is also a bit of a pussycat (yes, it has five rotating reciprocal alphabets) – the secondary trick here is the autokey, wherein the last plaintext letter of each group indicates which of the five alphabets to start the next group with.

The (once again, somewhat mysterious) keyword here is “SPAFXOT”:-

et per il contrario si marre conserva la sua profocsita (profundita)
et grandeza perche fluctrbu vien a sotiliare la rena et parte

mescolati sono sala virtu solare in aria levati et da li venti

Observant cryptologers will be pleased to note that Tony managed to crack both of these even though neither contained the word proportione. 🙂

Praise aside, all that I can say now is “Go, Tony, Go!” – good luck with the final cipher in the set!

    To me the codes above are impossible to solve, ive put my keys to solve the Beale treasure location codes on different sites and had little response there are no book keys, the keys are in the preceeding number to the one you want to decode, i have six related keys and here is the easiest example.
    71= 7+1= 8+7 = 15= O
    194=1+9+4=14+7=21=U
    38=3+8=11+7=18=R
    1701added=9+7=16=

    P,now ive pressed the wrong button and im giving upi know ive got farther than anyone else on finding the keys to decode Beals treasure location code i gave some keys on other sites in the hope someone will finsh the decode and verify im right there is a message to be found and a burial vaultand i know its IN THE COUNTY OF BEDFORD, JOINTLY OWNED,and the message ends, ON THE BALWONY,
    but i think the W for code number 820
    should be 826 which decodes to C
    making it ON THE BALCONY

    Hey Nick, some German guy deciphered the last cipher that Tony missed. Its a fairly short Latin prayer.

  4. Shurupag: cool – do you have a link etc?

    Nick: Here is the link:

    http://scienceblogs.de/klausis-krypto-kolumne/2016/04/05/blog-leser-loest-top-25-verschluesselungsraetsel/2/

    Some random wandering around the internet looking at ciphers led me a lad’s blog who mention it. I googled the solver’s name and sure enough I found that link.

    Hey Nick, as a matter of fact, I posted my solutions of 1555 #1, and 1564 #5, on your site some hours before I did on Klaus Schmeh’s blog:

    But I am glad to see that you heard about it, well, indirectly 🙂
