Citing Ben Morgan:

We will look at publishing these hashes for the source/data bundles on
the website, but cmake/Modules/Geant4DatasetDefinitions.cmake will
have to remain using MD5 for know because that is all CMake supports
in ExternalProject and file over the cmake version range we have to
support. We'll keep that under review though.

(It seems that only CMake 2.8.10 or 2.8.11 - not sure which one -
supports hashes other than MD5, see
https://github.com/Kitware/CMake/commit/beb8a8309bc0ce08e4884a59329607ac09c322ac.
And that version is relatively new.)
