• File libtommath/bn_mp_copy.c — part of check-in [c7a3a1452b] at 2016-03-11 17:13:38 on branch gahr-ticket-e6f27aa56f — [e6f27aa56f] Initial import of libtommath-1.0 This commit brings in libtommath-1.0, as of tag v1.0 of the upstream repository at https://github.com/libtom/libtommath. Only the top-level directory has been imported: the demo, etc, logs, mtest, pics, pre_gen, and tombc directories have been removed from our repo. The stubs tables have been regenerated to accomodate for the new function: mp_expt_d_ex(mp_int *a, mp_digit b, mp_int *c, int fast); See https://github.com/libtom/libtommath/commit/e9b1837 for details. Only the unix build system has been modified for now. Windows and Mac OSX will come later. (user: gahr size: 1359) [more...]
