Reproducing/verifying a release build

JBlake2's release builds are reproducible/verifiable since version 0.4. This means that you can reproduce the released jar by building JBlake2 from source. For more information on reproducible builds, see the reproducible-builds.org website.

To verify a particular release build, you'll need an x86_64 machine with GNU Bash (4.1+), Docker (17.05+), and, at your option, Mercurial or Git installed. First, clone the repository (either the official Mercurial repository or the Git mirror). Then, checkout the desired version tag. Finally, run the verify-build.sh script located at the project's root. This script recreates the build environment used to release the version, builds the project from source, downloads the released jar from Maven Central and checks that the build output matches (bit for bit) the downloaded artifact.
