Just to verify, when you add a cert to the supplemental folder mentioned here:

[https://docs.inductiveautomation.com/display/DOC80/Adding+Security+Certificates+into+KeyStores](https://docs.inductiveautomation.com/display/DOC80/Adding+Security+Certificates+into+KeyStores)

When you restart the machine, what actually happens is that the cert is added here:

`Inductive Automation\Ignition\lib\runtime\jre-win\lib\security\cacerts`

Is that correct?

Thanks,

Nick

Yes.

The supplemental location is used, and the certificates remain there, so in subsequent versions of Ignition where we've updated the bundled Java runtime they can be imported again.
