From 646257d1f4004855d486024527a4784bf57c4c4d Mon Sep 17 00:00:00 2001 From: Heiko Schocher Date: Mon, 3 Mar 2014 12:19:26 +0100 Subject: rsa: add sha256-rsa2048 algorithm 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 Cc: andreas@oetken.name Cc: Simon Glass --- common/image-sig.c | 38 ++++++++++++++++++++++++++++++++++++++ 1 file changed, 38 insertions(+) (limited to 'common') diff --git a/common/image-sig.c b/common/image-sig.c index 973b06d505f..8b6f49bb38e 100644 --- a/common/image-sig.c +++ b/common/image-sig.c @@ -14,15 +14,53 @@ DECLARE_GLOBAL_DATA_PTR; #endif /* !USE_HOSTCC*/ #include #include +#include #define IMAGE_MAX_HASHED_NODES 100 +#ifdef USE_HOSTCC +__attribute__((weak)) void *get_blob(void) +{ + return NULL; +} +#endif + +struct checksum_algo checksum_algos[] = { + { + "sha1", + SHA1_SUM_LEN, +#if IMAGE_ENABLE_SIGN + EVP_sha1, +#else + sha1_calculate, + padding_sha1_rsa2048, +#endif + }, + { + "sha256", + SHA256_SUM_LEN, +#if IMAGE_ENABLE_SIGN + EVP_sha256, +#else + sha256_calculate, + padding_sha256_rsa2048, +#endif + } +}; struct image_sig_algo image_sig_algos[] = { { "sha1,rsa2048", rsa_sign, rsa_add_verify_data, rsa_verify, + &checksum_algos[0], + }, + { + "sha256,rsa2048", + rsa_sign, + rsa_add_verify_data, + rsa_verify, + &checksum_algos[1], } }; -- cgit v1.2.3
