Hi Devs, I have submitted an WIP review (https://review.openstack.org/#/c/97900/) for Heat parameters encryption blueprint https://blueprints.launchpad.net/heat/+spec/encrypt-hidden-parameters This quick and dirty implementation encrypts all the parameters on on Stack 'store' and decrypts on on Stack 'load'. Following are couple of improvements I am thinking about; 1. Instead of encrypting individual parameters, on Stack 'store' encrypt all the parameters together as a dictionary [something like crypt.encrypt(json.dumps(param_dictionary))] 2. Just encrypt parameters that were marked as 'hidden', instead of encrypting all parameters I would like to hear your feedback/suggestions. Thanks, Vijendar
