Creates a file with checksums / hashes of all files in a directory (recursively) using extremely fast xxHash algorithm. You can create 64 bit and 128 bit (new XXH3) hashes.
Installation: place the file in ~/.local/share/kservices5/ServiceMenus
This project uses xxHash. Please, make sure 'xxhash' package is installed. XXH3 became stable in version 0.8.0, so I recommend this version or newer.
If your distro has old version, you can get newer one from Arch package (better check package signature before unpacking):
wget -qO xxhash.tzst https://www.archlinux.org/packages/community/x86_64/xxhash/download/ && sudo tar -C / -xvf xxhash.tzst usr/bin
See https://rurban.github.io/smhasher for comparison with other hash algorithms.
