The docs specify:
However I have tried writing to NVS with encryption enabled, but the contents appear to still be plain-text when I read back the flash dump. I have also seen other threads that indicate that it is not supported yet.NVS is compatible with the ESP32 flash encryption system, and it can store key-value pairs in an encrypted form. Some metadata, like page state and write/erase flags of individual entries can not be encrypted as they are represented as bits of flash memory for efficient access and manipulation.
Just wondering if this is supposed to be working now with the latest IDF (3.0), and if not, what the timeline might be for its support?
Thanks
