 When modules invoke the IoT Edge daemon's workload API to encrypt data, the encryption key is derived using the module ID and module's generation ID. A generation ID is used to protect secrets if a module is removed from the deployment and then another module with the same module ID is later deployed to the same device. You can view a module's generation ID using the Azure CLI command [az iot hub module-identity show](/cli/azure/iot/hub/module-identity).
