ESP32 Forum

I see the ESP32 supports secure boot and flash encryption:

I also see there is an AES based approach and in the ESP32V3 a PKI based approach:

Is the PKI support in the ESP32V3 limited to only these features or can we use this for other features, such as IoT Device Identity with Azure IoT Device Provisioning?

Thanks for the help!

There is no separate secure element hardware with private key storage. If you need that maybe you want wroom32-se? Otherwise just rely on secure boot and flash encryption to protect your keys. You could sign and verify your key partitions with the same PKI.

Sorry just saw your post. If you can use the ESP32-S2 in your application, the Digital Signature Peripheral may be helpful. It is explained here:

Thanks, I was checking if the ESP32 had similar security features as the S2. It does not, as you point out, the S2 is way to go for these needs.

Thank you !
