2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>
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.

2015-01-29rsa: Use checksum algorithms from struct hash_algoRuchika Gupta
Currently the hash functions used in RSA are called directly from the sha1 and sha256 libraries. Change the RSA checksum library to use the progressive hash API's registered with struct hash_algo. This will allow the checksum library to use the hardware accelerated progressive hash API's once available.

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>
