    $ sha256sum debian-9-turnkey-mumble_15.0-1_amd64.tar.gz
      64c113b31251ea5152fc8a3346f3bfc56627a76ab54abaeec3d9fccc082146c8  debian-9-turnkey-mumble_15.0-1_amd64.tar.gz

    $ sha512sum debian-9-turnkey-mumble_15.0-1_amd64.tar.gz
      c38d33ebec4bba104cb9a52ebdc992bbb680c1ec298986a2d4faa92f1e0686ea2d712504de1dcb772b421e1c416eee3d27091f0fbbb321abde339b975ed8fa72  debian-9-turnkey-mumble_15.0-1_amd64.tar.gz

   Note, you can compare hashes automatically::

    $ sha256sum -c debian-9-turnkey-mumble_15.0-1_amd64.tar.gz.hash
      debian-9-turnkey-mumble_15.0-1_amd64.tar.gz: OK

    $ sha512sum -c debian-9-turnkey-mumble_15.0-1_amd64.tar.gz.hash
