There's a RFP for this package from 2019 (#946635) already.

Monocypher is a small crypto library that provides a good selection of
primitives in ~2kloc.  The closest comparison would probably be
libsodium23, but that aims for a more higher-level API - and it's also
much larger, which isn't ideal for audit purposes.

This library is actually already in use by some Debian packages that
have vendored it: openttd, and a bunch of the tillitis-* stuff.

Personally, I'm interested in this package because I want to develop
software against it (it seems like the most sensible choice for my
needs), and I prefer installing dependencies via apt.

I've thus started working on a package.  I'm not a Debian developer but
I was told to submit an ITP anyways :)
