    Defend Dissent is an introduction to cryptography paired with the social impacts of surveillance and the protective potential of encryption, with a focus on US social movements. Each chapter ends with a story that brings social context to the material—from surveillance used against contemporary US protests to the African National Congress’s use of partially manual encryption in fighting apartheid in South Africa in the 80s.

The ancient Greeks, and the Spartans in particular, are said to have used this cipher to communicate during military campaigns. (CC BY-SA 3.0; Luringen via Wikipedia)
