  # Please Note:
  # We are currently adding two signatures to the msi.
  #
  # Microsoft compatable Signatures are composed of three different
  # elements.
  #   1) The Certificate used to sign the package. This is the element that
  #     is attached to organization. The certificate has an associated
  #     algorithm. We recently (February 2016) had to switch from a sha1 to
  #     a sha256 certificate. Sha1 was deprecated by many Microsoft
  #     elements on 2016-01-01, which forced us to switch to a sha256 cert.
  #     This sha256 certificate is recognized by all currently supported
  #     windows platforms (Windows 8/Vista forward).
  #   2) The signature used to attach the certificate to the package. This
  #     can be a done with a variety of digest algorithms. Older platforms
  #     (i.e., Windows 8 and Windows Vista) don't recognize later
  #     algorithms like sha256.
  #   3) The timestamp used to validate when the package was signed. This
  #     comes from an external source and can be delivered with a variety
  #     of digest algorithms. Older platforms do not recognize newer
  #     algorithms like sha256.
  #
  # We could have only one signature with the Sha256 Cert, Sha1 Signature,
  # and Sha1 Timestamp, but that would be too easy. The sha256 signature
  # and timestamp add more security to our packages. We can't have only
  # sha256 elements in our package signature, though, because Windows 8
  # and Windows Vista just don't recognize them at all.
  #
  # In order to add two signatures to an MSI, we also need to change the
  # tool we use to sign packages with. Previously, we were using SignTool
  # which is the Microsoft blessed program used to sign packages. However,
  # this tool isn't able to add two signatures to an MSI specifically. It
  # can dual-sign an exe, just not an MSI. In order to get the dual-signed
  # packages, we decided to switch over to using osslsigncode. The original
  # project didn't have support to compile on a windows system, so we
  # decided to use this fork. The binaries on the signer were pulled from
  # https://sourceforge.net/u/keeely/osslsigncode/ci/master/tree/
  #
  # These are our signatures:
  # The first signature:
  #   * Sha256 Certificate
  #   * Sha1 Signature
  #   * Sha1 Timestamp
  #
  # The second signature:
  #   * Sha256 Certificate
  #   * Sha256 Signature
  #   * Sha256 Timestamp
  #
  # Once we no longer support Windows 8/Windows Vista, we can remove the
  # first Sha1 signature.
