Encrypting device specific data
Posted: Mon Jul 23, 2018 2:12 pm
hello,
I need to load multiple esp32 devices with different data like certificates, configuration files etc. and encrypted them.
In a previous attempt I tried to use spiffs.. That went pretty much as expected.. easy build and flash
on each esp32..
When I enabled the encryption the spiffs partition didnt got encrypted because that is the way flash encryption works.
I need to have same firmware but different configuration data and all of them to be encrypted.
Embedding the configuration data (certs and files) in firmware is an option but this will add delay in production line because of the
different build for each esp32..
Has someone else encountered such a problem ?
Thanks,
Chris..
