[PATCH v9 04/11] tools: mkeficapsule: add firmware image signing

AKASHI Takahiro takahiro.akashi at linaro.org
Tue Jan 18 05:39:47 CET 2022


With this enhancement, mkeficapsule will be able to sign a capsule
file when it is created. A signature added will be used later
in the verification at FMP's SetImage() call.

To do that, we need specify additional command parameters:
  -monotonic-cout <count> : monotonic count
  -private-key <private key file> : private key file
  -certificate <certificate file> : certificate file
Only when all of those parameters are given, a signature will be added
to a capsule file.

Users are expected to maintain and increment the monotonic count at
every time of the update for each firmware image.
