(md_enable): Allocate contexts when flags.hmac is enabled. (md_copy): Remove macpads copying. Add copying contexts. (_gcry_md_reset): When flags.hmac is enabled, restore precomputed context with input pad (md_close): Remove macpads wiping. (md_final): When flags.hmac is enabled, compute hmac by precomputed context with output pad. (prepare_macpads): Prepare precomputed contexts with input pad and output pad for each registered digest entry. (_gcry_md_setkey): Just call prepare_macpads. -- This change is making things straight in HMAC computation. This makes HMAC computation allow multple algorithms in future. Libgcrypt's code has a potential to compute digests for multiple algorithms at once (currently, it's not enabled). HMAC code didn't work well with multple algorithms, because the macpads were only allocated for an algorithm. Now, it's allocated for each algorithm. We now precompute hash contexts, instead of keeping input pad and output pad. This can be performance improvement, which is described in RFC 2104.

2013-12-05Remove macro hacks for internal vs. external functions. Part 1.Werner Koch1-66/+66
* 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().

The test vectors have been produced by sha{1,224,256}sum and the genhashdata tool. A sequence of 'a' is used for them because a test using one million 'a' is commonly used for test vectors. More test vectors are required. Running the large tests needs to be done manual for now: ./hashtest --gigs 256 tests all algorithms, ./hashtest --gigs 256 sha1 sha224 sha256 only the given ones.

2011-12-01Completed switch to a simpler thread model.Werner Koch1-2/+6
This is only a first step. We will need to either implement pthread_atfork or - better - make use use POSIX RT semaphores.
2011-09-15Removed the module registration interfaceWerner Koch1-29/+0
The module registration interface is not widely used but complicates the internal operation of Libgcrypt a lot. It also does not allow for efficient implementation of new algorithm or cipher modes. Further the required locking of all access to internal module data or functions would make it hard to come up with a deadlock free pthread_atfork implementation. Thus we remove the entire subsystem. Note that the module system is still used internally but it is now possible to change it without breaking the ABI. In case a feature to add more algorithms demanded in the future, we may add one by dlopening modules at startup time from a dedicated directory.

2005-04-22ChangeLog:Moritz Schulte1-0/+3
2005-04-23 Moritz Schulte <moritz@g10code.com> * acinclude.m4 (TYPE_SOCKLEN_T): New type definition test; provided by Albert Chin. * configure.ac: Don't use $(CMD) as it's not portable; use `CMD` nstead. Simpler -lnsl/-lsocket test. Use TYPE_SOCKLEN_T test. Don't forget to set `random_modules' correctly. 2005-04-22 Moritz Schulte <moritz@g10code.com> * configure.ac: Added support for pkgconfig; provided by Albert Chin. cipher/ChangeLog: 2005-04-12 Moritz Schulte <moritz@g10code.com> * ac.c (_gcry_ac_io_write, _gcry_ac_io_read): Initialize err to make the compiler happy. Always use errno, now that gcry_malloc() is guaranteed to set errno on failure. (_gcry_ac_data_to_sexp): Don't forget to goto out after error in loop. (_gcry_ac_data_to_sexp): Remove unused variable: mpi_list; (_gcry_ac_data_to_sexp): Always deallocate sexp_buffer. (_gcry_ac_data_from_sexp): Don't forget to initialize data_set_new. (_gcry_ac_data_from_sexp): Handle special case, which is necessary, since gcry_sexp_nth() does not distinguish between "element does not exist" and "element is the empty list". (_gcry_ac_io_init_va): Use assert to make sure that mode and type are correct. Use gcry_error_t types where gcry_err_code_t types have been used before. mpi/ChangeLog: 2005-04-23 Moritz Schulte <moritz@g10code.com> * Makefile.am: Don't assume the compiler will pre-process the .S files. Some compilers, like those from HP and IBM, don't do this. So, we use the same solution gnupg-1.4.0 does. Preprocess first and then compile. * hppa1.1/mpih-mul3.S: Add "level 1.1" directive to disable warning about using PA-RISC1.1 opcodes. * hppa1.1/mpih-mul2.S: Likewise. * hppa1.1/mpih-mul1.S: Likewise. * hppa1.1/udiv-qrnnd.S: Likewise. src/ChangeLog: 2005-04-22 Moritz Schulte <moritz@g10code.com> * Makefile.am (pkgconfigdir, pkgconfig_DATA): New; support for pkgconfig provided by Albert Chin. * libgcrypt.pc.in (Cflags): New file. 2005-04-16 Moritz Schulte <moritz@g10code.com> * g10lib.h (_gcry_ac_init): Declare. * global.c (global_init): Call _gcry_ac_init; don't forget to set err. tests/ChangeLog: 2005-04-22 Moritz Schulte <moritz@g10code.com> * tsexp.c: Include <config.h> in case HAVE_CONFIG_H is defined; thanks to Albert Chin. * testapi.c: Likewise. * register.c: Likewise. * pubkey.c: Likewise. * prime.c: Likewise. * pkbench.c: Likewise. * keygen.c: Likewise. * benchmark.c: Likewise. * basic.c: Likewise. * ac-schemes.c: Likewise. * ac-data.c: Likewise. * ac.c: Likewise. 2005-04-16 Moritz Schulte <moritz@g10code.com> * ac-data.c (check_run): Include new test.
