b2sum

This is a simple tool to create BLAKE2 hashes of files or streams. For more usage information refer to the manpage, e.g., man b2sum.1.

Building and Installing

To build b2sum, just run make. To install, run make install. The install path can be altered using the PREFIX variable, which defaults to /usr/local. Use PREFIX=/some/path make install to install somewhere else.

b2sum makes use of OpenMP by default. Some compilers do not support this technology, in which case b2sum can be built without it using the NO_OPENMP variable. Use NO_OPENMP=1 make to build without OpenMP.

For OS X, there is a prebuilt Homebrew formula which may be installed with brew install b2sum.
