Cracking Codes with Python: An Introduction to Building and Breaking Ciphers
Dedicated to Aaron Swartz 1986 2013 Aaron was part of an army of citizens that believes democracy only works when the citizenry are informed when we know about our rights and our obligations An army that believes we must make justice and knowledge available to all not just the well born or those that have grabbed the reins of power so that we may govern ourselves more wisely When I see our army I see Aaron Swartz and my heart is broken We have truly lost one of our better angels Carl Malamud
