Dolphin service menu: xxHash - extremely fast directory checksum / hash

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.

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.

xxHash 0.8+ is available in Ubuntu 20.10+, Debian 11+, Fedora 32+, Arch, openSUSE Tumbleweed, etc.

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 SMhasher for comparison with other hash algorithms.
