 * This project supports `Linux`, `macOS`, `Windows` and other operating systems.
   * `Windows` version is currently released as an independent branch, using `iocp` to implement asynchronous networking. All user interfaces are consistent with the `Linux` version.
 * Supports all CPU platforms, including 32 or 64-bit `x86` processors, big-endian or little-endian `arm` processors.
-* Relies on `OpenSSL`; `OpenSSL 1.1` and above is recommended. If you don't like SSL, you may checkout the [nossl](https://github.com/sogou/workflow/tree/nossl) or the [stduy](https://github.com/sogou/workflow/tree/study) (no upstream) branch. But still need to link `crypto` for `md5` and `sha1`.

 * Uses the `C++11` standard and therefore, it should be compiled with a compiler which supports `C++11`. Does not rely on `boost` or `asio`.
 * No other dependencies. However, if you need `Kafka` protocol, some compression libraries should be installed, including `lz4`, `zstd` and `snappy`.
