Start with certificates

[cdupont]

I'm trying to follow the README file, but this instruction is not clear:

mosquitto_pub  -h localhost -p 8883 -V mqttv311 \
  --cafile "resources/hummingbird_ca.crt" \
  --cert "resources/mqtt-default.crt" \
  --key "resources/mqtt-default.key" \
  -t "abc/def" \
  -m "asdasd"

Where does come from the files hummingbird_ca.crt and mqtt-default.crt? They are not in the repo and are not generated by the create-self-signed-cert.sh script.
