Sicilian Mafia boss Bernardo Provenzano is among those best known for using pizzini, most notably in his instruction that Matteo Messina Denaro become his successor. The pizzini of other mafiosi have significantly aided police investigations.{{Cite news|author=Palazzolo, Salvo|date=13 November 2007|title=Palermo, nei "pizzini" del boss Lo Piccolo i nomi dei "soldati" delle cosche (Palermo, "pizzini" of boss Lo Piccolo name the "soldiers" of the mafia clan)|newspaper=La Repubblica|location=Rome, Italy|language=it|url=http://www.repubblica.it/2007/11/sezioni/cronaca/arrestati-lo-piccolo/vertici-boss/vertici-boss.html|archive-url=https://web.archive.org/web/20080623234420/http://www.repubblica.it/2007/11/sezioni/cronaca/arrestati-lo-piccolo/vertici-boss/vertici-boss.html|archive-date=23 June 2008|url-status=live}}
Provenzano case
Provenzano used a version of the Caesar cipher, used by Julius Caesar in wartime communications. The Caesar code involves shifting each letter of the alphabet forward three places; Provenzano's pizzini code did the same, then replaced letters with numbers indicating their position in the alphabet.{{cite web|url=http://dsc.discovery.com/news/briefs/20060417/mafiaboss_tec_02.html|title=Secret Mafia Notes Reveal New 'Godfather'|last=Lorenzi|first=Rossella|date=2006-04-25|work=Discovery News|publisher=Discovery Channel|access-date=26 June 2010|archive-url=https://web.archive.org/web/20060430111351/http://dsc.discovery.com/news/briefs/20060424/mafianote_tec.html|archive-date=2006-04-30}}
For example, one reported note by Provenzano read "I met 512151522 191212154 and we agreed that we will see each other after the holidays...". This name was decoded as "Binnu Riina".
