After I recently mentioned Bellaso’s set of seven challenge ciphers from 1564 on this blog, Augusto Buonafalce very kindly emailed me with scans of Bellaso’s three challenge ciphers from 1555. I’ve now transcribed these (as best I can) and have added them to the existing Bellaso cipher transcriptions page.

I do acknowledge that the font that my theme currently uses for “preformatted” text is too small (thanks Dennis!), but the ciphertexts are only really there to be cut-and-pasted into whatever hacky cryptanalysis package you choose. Incidentally, one neat little online crypto cipher package is John’s Javascript Secret-Code Systems webpage, which has a number of unsolved ciphertexts, such as the three “Richard Feynman” challenge ciphertexts (copied onto a Cipher Mysteries page).
