	  You can use either absolute or relative path.

	  In case relative path is used, the build system assumes that it starts

	  from the directory where the MCUBoot KConfig configuration file is

	  located. If the key file is not there, the build system uses relative

	  path that starts from the MCUBoot repository root directory.

	  The key file will be parsed by imgtool's getpub command and a .c source

	  with the public key information will be written in a format expected by

	  MCUboot.
