+# Introduction
+
+[libsodium](https://github.com/jedisct1/libsodium) is a new, easy-to-use software library for encryption, decryption, signatures, password hashing and more.
+
+**Source**: https://github.com/jedisct1/libsodium
+
+# Building
+
+Please build iwasm and wamrc, refer to:
+- [Build iwasm on Linux](../../../doc/build_wamr.md#linux), or [Build iwasm on MacOS](../../../doc/build_wamr.md#macos)
+- [Build wamrc AOT compiler](../../../README.md#build-wamrc-aot-compiler)
+
+And install [zig toolchain](https://ziglang.org/learn/getting-started), refer to [Install Zig from a Package Manager](https://github.com/ziglang/zig/wiki/Install-Zig-from-a-Package-Manager) for how to install it.
+
+And then run `./build.sh` to build the source code, the libsodium source code will be cloned, and test benchmarks of native version, wasm files and AOT files will be generated under `libsodium/zig-out/bin`.
+
+# Running
+
+Run `./run_aot.sh` to test the benchmark, the native mode and iwasm aot mode will be tested respectively.
+
+# Others
+
+Refer to [Performance of WebAssembly runtimes in 2023](https://00f.net/2023/01/04/webassembly-benchmark-2023) for more about the performance comparison of wasm runtimes on running the libsodium benchmarks.
