Notes
Bogus issue reported for esptool, also see
https://github.com/espressif/esptool/issues/926
Old revisions of one of the supported chipsets were using AES ECB for secure
boot and flash encryption, but newer ones have switched to newer cryptographic
algorithms. esptool keeps support for the older algorithms, in order to keep
the ability to work with older revisions of the hardware.
