  12 #                     VPN for this client (included in
  13 #                     /ssl-vpn/getconfig.esp response)

  16 #          exactly what this is the md5 digest *of*, but all that
  17 #          really matters is that the value in the HIP report
  18 #          submission should match the value in the HIP report check.
