Simple substitutions would likely be most common everywhere, but perhaps other methods clustered in certain areas?Broadly speaking ciphers used outside of politics/diplomacy tend to be simple substitution. Ciphers used by the Italian City States and their representatives tend to be much more complex, although normally still based on substitution. The most complex tend to be ciphers produced by the government of the Duchy of Milan. However, so little survives of the ciphers produced by the government of the Republic of Venice that we can't really say how complex their ciphers were in the early 15th century. The same could be said of the Papacy where so few examples of their ciphers from the early 15th century are known, although when I go to the Vatican Apostolic Archives maybe I will find a few examples. Even for Milan the picture is quite incomplete, although I am doing my best to form a more complete picture.
