--------------------------------------

hi Xiao,
this is a good feature and +1 for the feature itself.
However, I had a couple of suggestions.
* It would be great if this was made as a REST API endpoint along with the other key creation/management
REST API.
* May be we can add a new parameter to the key roll REST API saying something along the lines
of roll all the zones with given key, or change it to :
{code}

{
  "material"    : "<material>",
  "reencrypt"	: "True", // setting this to true will cause re encryption to begin.
  "zones"		: "a,c,b" // This will start it in the order of a->c->b
}
{code}
* Create an endpoint to check the status or reencryption.

> Currently when an encryption zone (EZ) key is rotated, it only takes effect on new EDEKs.
We should provide a way to re-encrypt EDEKs after the EZ key rotation, for improved security.
