Activate secure boot and flash encryption on recorded ESP32

[CamargoF]

I create a batch file that upload the binary file directly to ESP32 using esptool.

Now I would like to now how can I use the esptool to activate the secure boot and the flash encryption on preloaded ESP32 firmware, using a random key. For security reason I don't to get the key, just protect the code against external attacks.

I appreciate any help.

Best regards,

Fernando
