2015-08-08Add framework to eventually support SHA3.Werner Koch1-0/+11
* src/gcrypt.h.in (GCRY_MD_SHA3_224, GCRY_MD_SHA3_256) (GCRY_MD_SHA3_384, GCRY_MD_SHA3_512): New. (GCRY_MAC_HMAC_SHA3_224, GCRY_MAC_HMAC_SHA3_256) (GCRY_MAC_HMAC_SHA3_384, GCRY_MAC_HMAC_SHA3_512): New. * cipher/keccak.c: New with stub functions. * cipher/Makefile.am (EXTRA_libcipher_la_SOURCES): Add keccak.c. * configure.ac (available_digests): Add sha3. (USE_SHA3): New. * src/fips.c (run_hmac_selftests): Add SHA3 to the required selftests. * cipher/md.c (digest_list) [USE_SHA3]: Add standard SHA3 algos. (md_open): Ditto for hmac processing. * cipher/mac-hmac.c (map_mac_algo_to_md): Add mapping. * cipher/hmac-tests.c (run_selftests): Prepare for tests. * cipher/pubkey-util.c (get_hash_algo): Add "sha3-xxx". -- Note that the algo GCRY_MD_SHA3_xxx are prelimanry. We should try to sync them with OpenPGP. Signed-off-by: Werner Koch <wk@gnupg.org>
2013-12-05Remove macro hacks for internal vs. external functions. Part 1.Werner Koch1-1/+1
* src/visibility.h: Remove almost all define/undef hacks for symbol visibility. Add macros to detect the use of the public functions. Change all affected functions by prefixing them explicitly with an underscore and change all internal callers to call the underscore prefixed versions. Provide convenience macros from sexp and mpi functions. * src/visibility.c: Change all functions to use only gpg_err_code_t and translate to gpg_error_t only in visibility.c. -- The use of the macro magic made if hard to follow the function calls in the source. It was not easy to see if an internal or external function (as defined by visibility.c) was called. The change is quite large but hopefully makes Libgcrypt easier to maintain. Some function have not yet been fixed; this will be done soon. Because Libgcrypt does no make use of any other libgpg-error using libraries it is useless to always translate between gpg_error_t and gpg_err_code_t (i.e with and w/o error source identifier). This translation has no mostly be moved to the function wrappers in visibility.c. An additional advantage of using gpg_err_code_t is that comparison can be done without using gpg_err_code(). I am sorry for that large patch, but a series of patches would actually be more work to audit. Signed-off-by: Werner Koch <wk@gnupg.org>
