[$] Zinc: a new kernel cryptography API

We looked atthe WireGuard virtual privatenetwork (VPN)back in August and noted that it is built on top of a newcryptographic API being developed for the kernel, which is calledZinc. There has been some controversy about Zinc and why a brand new API was needed when the kernel already has an extensive crypto API. A recenttalk by lead WireGuard developer Jason Donenfeld at Kernel Recipes 2018 would appear to be a serious attempt to reach out, engagewith that question, and explain the what, how, and why of Zinc.
