### AI overview

This article explains how to exercise ESP32-C3 security features under QEMU before deploying them to real hardware. It describes the risks of irreversible eFuse programming, QEMU's ESP32-C3 system emulation and firmware compatibility, and workflows for testing security configurations.

### Source excerpt

Overview# ESP32 series of SoCs supports multiple security features like trusted boot, flash encryption, secure storage etc. There are also dedicated peripherals to support use-cases like HMAC and digital signature. For most of these features the eFuse storage in the ESP32-C3 is responsible for storing the private keys and also the configuration bits. eFuse memory is one time programmable and hence care must be taken whilst enabling the security features.
