>Description:
The import of libsodium into the kernel, under sys/crypto/sodium and sys/external/isc/libsodium, has some glue code that needs review, and as a crypto component the functionality needs self-tests.

Fortunately nothing uses it besides the still-experimental-and-not-production-ready wg(4).
