This talk will present the new NetBSD kernel entropy subsystem after it was rewritten in 2020. The talk will cover the design and rationale of the new implementation, how it addresses various performance and security concerns, a high-level overview of the underlying cryptography, and issues with userland APIs and the repercussions of blocking.
