hash.sh returns just the sha256sum of its input file checkhash.sh uses ha.sh to get the sha256sum of its first argument and then validates that the checksum matches the value provided in its second argument hash.sh isn't currently fully portable since sha256sum isn't present by default on macOS, but it provides a single point around which we can do hashing to validate checksums Signed-off-by: Ashley Davis <ashley.davis@jetstack.io>
