This cryptographical collection originates from the year 1475 and was penned by Francesco Tranchedino, an associate of the renowned Cicco Simonetta, who led the Sforza's private secretariat in Milan and was also among the earliest significant theorists in cryptography. Originating from the library of Philip Edward Fugger, the manuscript is partially inscribed by Tranchedino himself. It encompasses six deciphered ciphers, alongside 287 complete and four partial "keys" that were utilized within the aforementioned chancellery. However, not all entries qualify as actual keys; the manuscript also uses arbitrary symbols to represent the plaintext alphabet, digraphs, trigraphs, and more.

Included is a code or lexicon, predominantly composed of proper nouns, accompanied by their coded equivalents. Interspersed within the genuine ciphers are numerous "dummies" — meaningless symbols included to thwart deciphering efforts. Notably, the vowels are assigned more cryptographic symbols than consonants, reflecting their anticipated higher occurrence in Italian text.

International social justice movements and the debates that ensued prompted us to start considering the contents of our website from a critical point of view. This has led us to acknowledge that most of the texts in our database are Western-centered. We have asked the authors of our content to be aware of the underlying racial and cultural bias in many scholarly sources, and to try to keep in mind multiple points of view while describing the manuscripts. We also recognize that this is yet a small, first step towards fighting inequality.

If you notice any trace of racist or unjust narratives in our communications, please help us be part of the change by letting us know.
