Add XXH? #1

I've just installed xxhsum, and implementing both 32- and 64-bit will surely not be a problem. When I start working on the new version (see the other thread), it'll be a Platypus application with its own /bin directory containing CLIs for xxHash, IPFS multihash, bencode torrent hash, dbhash (sqlite), rhash for SHA-3 etc.

Question about xxHash regarding checksum file support: do you know a link to demo files bundled with an XXH checksum file, i.e. something like files.xxh? (No rush, though.)

I've not encountered any such XXH checksum files

No problem. According to the man page, the default way to create them is

xxhsum -H0 foo bar baz > xyz.xxh32
xxhsum -H1 foo bar baz > qux.xxh64

So it should be sufficient to manually create them and tell the script how to find & parse them.
