      tools, fit_check_sign: verify a signed fit image · 29a23f9d
      Heiko Schocher authored
      add host tool "fit_check_sign" which verifies, if a fit image is
      signed correct.

      rsa: add sha256-rsa2048 algorithm · 646257d1
      Heiko Schocher authored
      based on patch from andreas@oetken.name:
      commit message:
      I currently need support for rsa-sha256 signatures in u-boot and found out that
      the code for signatures is not very generic. Thus adding of different
      hash-algorithms for rsa-signatures is not easy to do without copy-pasting the
      rsa-code. I attached a patch for how I think it could be better and included
      support for rsa-sha256. This is a fast first shot.
      aditionally work:
      - removed checkpatch warnings
      - removed compiler warnings
      - rebased against current head

      image: Add RSA support for image signing · 19c402af
      Simon Glass authored
      RSA provides a public key encryption facility which is ideal for image
      signing and verification.
      Images are signed using a private key by mkimage. Then at run-time, the
      images are verified using a private key.
      This implementation uses openssl for the host part (mkimage). To avoid
      bringing large libraries into the U-Boot binary, the RSA public key
      is encoded using a simple numeric representation in the device tree.
