Compiling from main DOES work.

So it is just a matter of releasing new version...

Notice that

This formula is referencing

url "https://github.com/rnpgp/rnp/archive/refs/tags/v0.16.3.tar.gz"

and not 0.17.0

However, 0.17.0 does NOT work either, and it will not solve the problem.

What we need is hopefully soon, a new release from Main.

this will probably solve #33 also

Thanks

@shemeshg thanks for opening this issue. Botan3 support was added only recently to the main, and will be included into the next release. Sometimes homebrew rushes with including only the latest version of libraries/tools.

@ni4 perhaps it's time to update this formula!
