* rsa: Verify RSA padding programaticallyAndrew Duda2016-11-21-4/+0
| | | | | | | | | | | | | | | | | | | 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.

* rsa: Use checksum algorithms from struct hash_algoRuchika Gupta2015-01-29-4/+13
| | | | | | | | | | | | | | | 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.

* includes: move openssl headers to include/u-bootJeroen Hofstee2014-06-19-0/+24
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>
