Cryptography - Edward Knapp

Title: Implementing cryptography at scale 

Abstract: Many cryptographic primitives have rough edges which make them difficult to use properly (by both experts and non-experts). We can mitigate this by encapsulating dangerous primitives in higher-level APIs and protocols. We survey various modern crypto primitives, discussing where they're used, why they're used, how they've been historically misused, and what goes wrong when they're misused.
