ESP32

Postby dcarvalho » Fri Sep 27, 2019 12:25 pm

Hello,

How does ESP32 saves/stores the private key? Is it secure? Is it hacker proof? And if somehow there is an "code reader" from the microcontroller, does this micro has protective fail safe countermeasure?
Isn't the private key exposed when building, for example, JWT? Or, in last instance, when we send data to the cloud?

Regards,
Daniele

Bad title.

User can store it in encrypted flash or encrypted nvs

Is it secure? Is it hacker proof? And if somehow there is an "code reader" from the microcontroller, does this micro has protective fail safe countermeasure?
Relatively secure, not 100%.

Isn't the private key exposed when building, for example, JWT? Or, in last instance, when we send data to the cloud?
No

Sounds like you need a security consultant
