        Build a bootloader with the secure boot flag enabled.

        Secure bootloader can be one-time-flash (chip will only ever
        boot that particular bootloader), or a digest key can be used
        to allow the secure bootloader to be re-flashed with
        modifications. Secure boot also permanently disables JTAG.

        See docs/security/secure-boot.rst for details.

       bool "Disabled"

config SECURE_BOOTLOADER_ONE_TIME_FLASH
       bool "One-time flash"
       help
           On first boot, the bootloader will generate a key which is not readable externally or by software. A digest is generated from the bootloader image itself. This digest will be verified on each subsequent boot.

           Enabling this option means that the bootloader cannot be changed after the first time it is booted.

config SECURE_BOOTLOADER_REFLASHABLE
    bool "Reflashable"
    help
        Generate the bootloader digest key on the computer instead of inside
        the chip. Allows the secure bootloader to be re-flashed by using the
        same key.

        This option is less secure than one-time flash, because a leak of the digest key allows reflashing of any device that uses it.

       Path to the key file for a reflashable secure bootloader digest.
       File must contain 32 randomly generated bytes.

       Path is evaluated relative to the project directory.

       You can generate a new key by running the following command:
       espsecure.py generate_key secure_boot_key.bin

        Path to the key file used to sign partition tables and app images for secure boot.

        Key file is an ECDSA private key (NIST256p curve) in PEM format.

        Path is evaluated relative to the project directory.

        You can generate a new signing key by running the following command:
        espsecure.py generate_signing_key secure_boot_signing_key.pem

        See docs/security/secure-boot.rst for details.
