* tools, fit_check_sign: verify a signed fit imageHeiko Schocher2014-03-21-8/+22
| | | | | | | | add host tool "fit_check_sign" which verifies, if a fit image is signed correct. Signed-off-by: Heiko Schocher <hs@denx.de> Cc: Simon Glass <sjg@chromium.org>
* rsa: add sha256,rsa4096 algorithmHeiko Schocher2014-03-21-16/+69

* rsa: add sha256-rsa2048 algorithmHeiko Schocher2014-03-21-64/+129
| | | | | | | | | | | | | | | | | | | | | based on patch from andreas@oetken.name: http://patchwork.ozlabs.org/patch/294318/ 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 Signed-off-by: Heiko Schocher <hs@denx.de> Cc: andreas@oetken.name Cc: Simon Glass <sjg@chromium.org>

| | | | | | | | | | | | | Interfaces exposed by error.h seems not to be used in rsa-sig.c, remove it. This also fixes an compile error on OS X: ---8<--- u-boot/lib/rsa/rsa-sign.c:23:19: error: error.h: No such file or directory --->8--- Signed-off-by: Andreas Bießmann <andreas.devel@googlemail.com> Acked-by: Jeroen Hofstee <jeroen@myspectrum.nl> Tested-by: Lubomir Popov <lpopov@mm-sol.com>
* image: Add RSA support for image signingSimon Glass2013-06-26-0/+893
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. Signed-off-by: Simon Glass <sjg@chromium.org>
