CONFIG_BOOT_SIGNATURE_KEY_FILE

MCUBoot PEM key file

Type: string

Help

Absolute path to PEM key file containing the private key corresponding
to the public key included in MCUBoot. This will be used to sign the
image so that it can be verified by MCUBoot. Since MCUBoot is not
built from source, it is not possible for the build system to deduce
what key was used when compiling it. Hence, it is required that the
key is passed to the build system through this option.

Direct dependencies
