Concealing for Freedom: The Making of Encryption, Secure Messaging and Digital Liberties sets out to explore one of the core battlegrounds of Internet governance: the encryption of online communications. Current debates around encryption have fundamental implications for our individual liberties and collective presence on the Internet. Encryption of communications at scale and in increasingly usable ways has become a matter of public concern, especially since Edward Snowden’s 2013 revelations. A new cryptographic imaginary is taking hold, which sees encryption as a necessary precondition for the formation of networked publics. At the same time, there have been major evolutions and accelerations in the field of secure communications, prompted in part by the cryptography community’s renewed efforts to create next-generation secure messaging protocols and applications. It is vital that we unveil the very recent, and sometimes less recent history of these protocols and their key applications. The book takes on this task, in order to show how the opportunities and constraints they provide to Internet users came about, and how both developer communities and institutions are working towards making them available for the largest possible audience.
