openssl zig package

This is openssl ported to the Zig Build System.

Artifacts

Two, matching upstream's own division:

const openssl = b.dependency("openssl", .{ .target = target, .optimize = optimize });
module.linkLibrary(openssl.artifact("crypto")); // libcrypto.a — primitives
module.linkLibrary(openssl.artifact("ssl"));    // libssl.a — the TLS stack

They emit libcrypto.a and libssl.a, so a consumer whose linker asks for -lcrypto resolves it by name. ssl links crypto itself; the dependency runs one way and never back.

Link only what you use. A consumer that implements TLS itself and wants the primitives links crypto alone and never compiles the 95-file TLS protocol stack — which is the point of two artifacts rather than one archive the linker is trusted to prune.

Upgrading from the single artifact("openssl"): that name is gone. Pins are by content hash, so nothing breaks until you move your pin, and when you do it is one line per consumer.

Status

I was able to use this to build CPython for x86_64-linux.

Adding support for other operating systems and CPU architectures is straightforward and will require fiddling with the build script to take into account the target.

Anti-Endorsement

I do not endorse openssl. I think it is a pile of trash. My motivation for this project is because it is a dependency of CPython, which is a dependency of the most active YouTube downloader, ytdlp.
