      -a {a}, --algo {a}      set hashing algorithm to {a}, default is sha256
                              options: see -A

      -H, --hashes            display all available hashing algorithms and exit

                              options: hex, latin1, base64

      -i, --input             print input along with hash, seperated by tab
