Hi everyone,

I’ve recently added support for custom SSL libraries in [`nginx-build`](https://github.com/cubicdaiya/nginx-build) as of version **v0.16.0**.

You can now build nginx with SSL libraries like **[OQS-Provider](https://github.com/open-quantum-safe/oqs-provider)** and **[BoringSSL](https://github.com/google/boringssl)** using the new `-customssl` option.

### 🛠 Example: Build with OQS-Provider

```bash
nginx-build \
  -d work \
  -customssl https://github.com/open-quantum-safe/oqs-provider.git \
  -customsslname oqs-provider \
  -customssltag 0.9.0

```

This mechanism is generic and flexible, so you can try any custom SSL implementation that works with nginx.

Because the potential use cases are quite broad, I’d really appreciate any feedback if you try this in a real-world setup—or even just let me know what libraries you’re experimenting with.

Thanks!

This is so cool! Thanks for showing us, @catatsuy. I love that the use cases are broad. Also curious how folks will use it.

I’ll be sure to pass this along to other folks in NGINX too–perfect example of these great community efforts.
