2016-11-21rsa: Verify RSA padding programaticallyAndrew Duda
Padding verification was done against static SHA/RSA pair arrays which take up a lot of static memory, are mostly 0xff, and cannot be reused for additional SHA/RSA pairings. The padding can be easily computed according to PKCS#1v2.1 as: EM = 0x00 || 0x01 || PS || 0x00 || T where PS is (emLen - tLen - 3) octets of 0xff and T is DER encoding of the hash. Store DER prefix in checksum_algo and create rsa_verify_padding function to handle verification of a message for any SHA/RSA pairing.

2014-06-19includes: move openssl headers to include/u-bootJeroen Hofstee
commit 18b06652cd "tools: include u-boot version of sha256.h" unconditionally forced the sha256.h from u-boot to be used for tools instead of the host version. This is fragile though as it will also include the host version. Therefore move it to include/u-boot to join u-boot/md5.h etc which were renamed for the same reason. cc: Simon Glass <sjg@chromium.org> Signed-off-by: Jeroen Hofstee <jeroen@myspectrum.nl>
2014-05-12lib/sha256: fix compile on some hostsAndreas Bießmann
Commit 2842c1c24269a05142802d25520e7cb9035e456c introduced lib/sha256 into mkimage. Since then it will be compiled with HOSTCC which may produce errors on some systems. Most BSD systems (like OS X for me) do not ship a linux/string.h which will lead to take the U-Boot provided include/linux/string.h in the end. This header howver is completely wrong here. Just take the string.h if compiling with HOSTCC and linux/string.h when not.

2012-12-11sha256: Use const where possible and add watchdog functionSimon Glass
In preparation for making the hash function common, we may as well use const where we can. Also add a watchdog version of the hashing function. Signed-off-by: Simon Glass <sjg@chromium.org>
2010-04-13Rename lib_generic/ to lib/Peter Tyser
Now that the other architecture-specific lib directories have been moved out of the top-level directory there's not much reason to have the '_generic' suffix on the common lib directory. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
