Flash encryption is intended for encrypting the contents of off-chip flash memory.
What does that exactly mean? Does it only make sense for an ESP chip that has a separate flash chip attached via SPI?
Or is it also necessary for ESP chips that have "internal" flash in a SiP configuration, like a ESP8684H4 for example?
I would guess that the latter is already protected by the package and the flash is not accessible from the outside.
What is the general recommendation here? Any thoughts or experience from the forum?
Thanks for all helpful feedback.
