highwayhashsum

This is minio/highwayhash, a blazin' fast hash algorithm for large files. This implementation is built to behave like the more well-known hashing tools from coreutils (md5sum, sha512sum etc.).

Note that highwayhash uses an arbitrary "key" seed for hash generation. This implementation uses 12345678901234567890123456789012 and will thus generate different hashes to implementations with other seeding keys.
