# LibreSSL
This is [LibreSSL Portable](https://github.com/libressl/portable), packaged for [Zig](https://ziglang.org/).
## Status
This project currently builds the three main LibreSSL libraries as static libraries:
- `libcrypto`: core cryptographic routines
- `libssl`: OpenSSL 1.1 compatibility layer
- `libtls`: LibreSSL's new cryptography API
Operating systems and hardware architectures are supported on a best-effort basis. Building for Linux, macOS, and Windows (mingw64) is directly tested by CI.
The command-line programs `nc`, `ocspcheck`, and `openssl` are not built by default, and building them when targeting Windows is not supported. Building the command-line programs may be enabled by specifing the `-Dbuild-apps` option to `zig build`
## Usage
First, update your `build.zig.zon`:
```sh
# Initialize a `zig build` project if you haven't already
zig init
# replace <refname> with the version you want to use, e.g. 3.9.2
zig fetch --save git+https://github.com/allyourcodebase/libressl#<refname>
```
You can then use `libressl` in your `build.zig` as follows:
```zig
const libressl_dependency = b.dependency("libressl", .{
.target = target,
.optimize = optimize,
.@"enable-asm" = true, // enable assembly routines on supported platforms
});
your_exe.linkLibrary(libressl_dependency.artifact("tls")); // or "ssl", or "crypto"
```
