Secure boot + flash encryption + Arduino BIN file

[greddy]

Hey - did you guys figure out a way to do this?

Specifically, looking for step-by-step instructions for taking a XXX.bin from an Arduino-compiled ESP32 project,
and using only the command line tools (esptool.py, espefuse.py, espsecure.py) to
1) set up secure boot (V2?)
- creating keys
- sign binaries
2) set up file encryption
- create keys
- sign firmware
3) create signed and encrypted OTA firmware files (.bin)
