## Zig-SM3 

zig-sm3 is a SM3 hash function for Zig.


### Env

 - Zig >= 0.16.0


### Adding zig-sm3 as a dependency

Add the dependency to your project:

```sh
zig fetch --save=zig-sm3 git+https://github.com/deatil/zig-sm3#main
```

or use local path to add dependency at `build.zig.zon` file

```zig
.{
    .dependencies = .{
        .@"zig-sm3" = .{
            .path = "./lib/zig-sm3",
        },
        ...
    },
    ...
}
```

And the following to your `build.zig` file:

```zig
    const zig_sm3_dep = b.dependency("zig-sm3", .{});
    exe.root_module.addImport("zig-sm3", zig_sm3_dep.module("zig-sm3"));
```

The `zig-sm3` structure can be imported in your application with:

```zig
const zig_sm3 = @import("zig-sm3");
```


### Get Starting

~~~zig
const std = @import("std");
const SM3 = @import("zig-sm3").SM3;

pub fn main(init: std.process.Init) !void {
    _ = init;

    var out: [32]u8 = undefined;
    
    var h = SM3.init(.{});
    h.update("abc");
    h.final(out[0..]);
    
    // output: 66c7f0f462eeedd9d1f2d46bdc10e4e24167c4875cf2f7a2297da02b8f4ba8e0
    std.debug.print("output: {x}\n", .{out});
}
