xksProxyUriEndpoint

Changes the URI endpoint that KMS uses to connect to your external key store proxy (XKS proxy). This parameter is valid only for custom key stores with a CustomKeyStoreType of EXTERNAL_KEY_STORE.

For external key stores with an XksProxyConnectivity value of PUBLIC_ENDPOINT, the protocol must be HTTPS.

For external key stores with an XksProxyConnectivity value of VPC_ENDPOINT_SERVICE, specify https:// followed by the private DNS name associated with the VPC endpoint service. Each external key store must use a different private DNS name.

The combined XksProxyUriEndpoint and XksProxyUriPath values must be unique in the Amazon Web Services account and Region.

To change this value, the external key store must be disconnected.
