David Garske
4cbfec1c7d Implemented ksdk_port fixes to handle mp_ response codes. Added KSDK support for normal math. Regression testing against K82 hardware (MMCAU/LTC) and software with normal and fast math. 2017-02-21 14:03:21 -08:00
David Garske
3008c888bf Fix mp_cmp_d logic to handle a->used == 0. Revert mp_copy and mp_set 0 size workarounds. 2017-02-21 14:03:21 -08:00
David Garske
9c7407d18c Added return codes to wc_InitDhKey, wc_InitDsaKey and mp_set. Added missing return code checks on mp_copy in ecc.c. Fixed build with DSA and no ECC where mp_set function def would be missing. 2017-02-21 14:03:21 -08:00
David Garske
da5825b94d Normal math speed-up to not allocate on mp_int and defer until mp_grow. Added memory tracker support to ./tests/unit.test. Fix memory leak with curve cache enabled, by adding to wolfSSL_Cleanup. 2017-02-21 13:59:38 -08:00

4f53761faf Fix naming for integer.c min/max local variables to resolve reported “error: declaration of 'min' shadows a global declaration”. 2017-02-09 15:52:25 -08:00

6d5485b88f Fix to "mp_init_multi" so failure ensures a later "mp_clear" won't free on un-initialized pointer. Applies to !USE_FAST_MATH only. No measurable benchmark difference. 2016-11-11 20:03:58 -08:00

dd52af0872 ECC cleanup / fixes. Improvements to ECC with fast math enabled to avoid mp_clear on stack variables. Refactor of ECC failure cleanup (fixes possible mem leaks with small stack enabled). Refactor of "fp_is*" response checks to use FP_YES or FP_NO. Pulled libtom enhancement/cleanup of fp_isprime. Fix for compressed keys import with custom curves (still having some issues though). 2016-06-21 15:27:51 -07:00
David Garske
aa1a405dd1 Fixes for compressed keys. Fix to fast math "mp_cnt_lsb" to return proper value, which fixes "mp_jacobi", which fixes "mp_sqrtmod_prime", which fixes compressed keys for 224-bit key. Removed workarounds for compressed keys. Added new configure option "--enable-compkey". Fixed issue with normal math and custom curves where "t2" could be free'd and used. Fixed issue with mp_dump in integer.c, with not allocating correctly sized buffer for toradix. 2016-06-21 14:06:02 -07:00
David Garske
5703e5eadb ECC changes to support custom curves. Added new "WOLFSSL_CUSTOM_CURVES" option to support non-standard ECC curves in ecc_is_point and ecc_projective_dbl_point. Refactor to load and pass curve "a" parameter down through ECC functions. Relocated mp_submod and added mp_addmod. Refactor to pass mp variable directly (not pointer) for montgomery variable. Fix in mp_jacobi to also handle case of a == 0. Cleanup of *_ecc_mulmod and wc_ecc_make_key_ex error handling. Cleanup of ecc_map for handling normal, fast and alt_ecc math for optimization of performance and allowing reduced ecc_size. 2016-06-15 08:41:51 -07:00
David Garske
87c00eb3f3 Math updates from libtom. Fixes in mp_read_radix for to include char 36 and clear the destination before checks. Fix to clear tmp value on fp_sub_d and fp_add_d. Fixes in assembly for x86-32 INNERMUL, PPC32 INNERMUL and PROPCARRY and x86-64 SQRADD. Added mp_isneg. Refactor of mp_iszero, mp_iseven, mp_isodd and mp_isneg to check using MP_YES or MP_NO. Changed fp_read_unsigned_bin "b" arg to const. Removal of the "register" on stack variables to let compiler determine best optimization. 2016-06-14 16:56:22 -07:00
David Garske
2ad9d41641 Performance improvement for fast math mp_clear to use fp_zero (memset) instead of fp_clear(ForceZero). Added new mp_forcezero function for clearing/free'ing sensitive private key data. Changed ECC and RSA to use mp_forcezero to explicitly handle private key clearing. 2016-05-12 11:50:34 -07:00
David Garske
440956f8d4 Fixed new issue with ecc_projective_add_point not free'ing the local x, y, z if fast math was disabled. Formatting cleanup in integer.c. 2016-05-11 08:47:30 -07:00
David Garske
5cbc4bdf29 Added new "WOLFSSL_DEBUG_MATH", which enables use of "mp_dump" to display information about an mp_int. 2016-05-09 09:51:11 -07:00
