Quick start


Ubuntu Linux (64-bit) is the primary development platform for sdhash; this means that any alpha stage releases may only be available on Linux. However, all beta and regular releases are supported on all three platforms.

The code base has largely been decoupled from the underlying platform dependencies by using appropriate high-level libraries. (All libraries have compatible licences–Apache, BSD, MIT, or similar–no GPL.) One of the big benefits is that the code has become cleaner and there are no conditional compilation statements.


Everything related to sdhash–code, documentation, presentations, etc.–is maintained at The code repo is publicly available at


We provide 32-/64-bit both deb and rpm packages, which are tested on recent versions of Ubuntu and Fedora (as indicated). There is also a deb package for Apache Thrift, which can simplify the build for the client/server version.

You can also build from source and that tends to work reliably (let us know otherwise!).


Since version 2.2, we provide 32-/64-bit native executables for MS Windows, which should worked on current versions of Windows.

The Windows port of the code is built with MSVC and come as a self-contained executable with all libraries bundled in. It supports parallel processing and measured performance is comparable to Linux. Build instructions are provided, if you need to experiment.


Mac users need to build from source (for now); we test the build process on Mac before release, and it works reliably.
