It clearly *should* be possible to make crypto API call into zinc for synchronous software operations, but a demonstration of how this actually works and that there isnât some change to zinc to make it would well would be in order, I think.

It turned out to be fairly straight forward and quick to do. I'm on a
transatlantic plane so the connection is super spotty, but you can
check out the three commits added to:
<https://git.kernel.org/pub/scm/linux/kernel/git/zx2c4/linux.git/log?h=jd/wireguard>
-- the two "crypto:" commits and the one "random:" commit.
Alternatively, you can look directly at
<https://git.kernel.org/pub/scm/linux/kernel/git/zx2c4/linux.git/tree/crypto/poly1305_zinc.c?h=jd/wireguard>
and <https://git.kernel.org/pub/scm/linux/kernel/git/zx2c4/linux.git/tree/crypto/chacha20_zinc.c?h=jd/wireguard>.
I'll be refining and checking these over the next week or so, but the
basics were super easy to do.
