Jan 17th, 2003 v0.12 -- re-wrote the majority of the makefile so its more portable and will install via "make install" on most *nix platforms -- Re-packaged all the source as seperate files. Means the library a single file packagage any more. Instead of just adding "bn.c" you have to add libtommath.a -- Renamed "bn.h" to "tommath.h" -- Changes to the manual to reflect all of this -- Used GNU Indent to clean up the source Jan 15th, 2003 v0.11 -- More subtle fixes -- Moved to gentoo linux [hurrah!] so made *nix specific fixes to the make process -- Sped up the montgomery reduction code quite a bit -- fixed up demo so when building timing for the x86 it assumes ELF format now Jan 9th, 2003 v0.10 -- Pekka Riikonen suggested fixes to the radix conversion code. -- Added baseline montgomery and comba montgomery reductions, sped up exptmods [to a point, see bn.h for MONTGOMERY_EXPT_CUTOFF] Jan 6th, 2003 v0.09 -- Updated the manual to reflect recent changes. :-) -- Added Jacobi function (mp_jacobi) to supplement the number theory side of the lib -- Added a Mersenne prime finder demo in ./etc/mersenne.c Jan 2nd, 2003 v0.08 -- Sped up the multipliers by moving the inner loop variables into a smaller scope -- Corrected a bunch of small "warnings" -- Added more comments -- Made "mtest" be able to use /dev/random, /dev/urandom or stdin for RNG data -- Corrected some bugs where error messages were potentially ignored -- add etc/pprime.c program which makes numbers which are provably prime. Jan 1st, 2003 v0.07 -- Removed alot of heap operations from core functions to speed them up -- Added a root finding function [and mp_sqrt macro like from MPI] -- Added more to manual Dec 31st, 2002 v0.06 -- Sped up the s_mp_add, s_mp_sub which inturn sped up mp_invmod, mp_exptmod, etc... -- Cleaned up the header a bit more Dec 30th, 2002 v0.05 -- Builds with MSVC out of the box -- Fixed a bug in mp_invmod w.r.t. even moduli -- Made mp_toradix and mp_read_radix use char instead of unsigned char arrays -- Fixed up exptmod to use fewer multiplications -- Fixed up mp_init_size to use only one heap operation -- Note there is a slight "off-by-one" bug in the library somewhere without the padding (see the source for comment) the library crashes in libtomcrypt. Anyways a reasonable workaround is to pad the numbers which will always correct it since as the numbers grow the padding will still be beyond the end of the number -- Added more to the manual Dec 29th, 2002 v0.04 -- Fixed a memory leak in mp_to_unsigned_bin -- optimized invmod code -- Fixed bug in mp_div -- use exchange instead of copy for results -- added a bit more to the manual Dec 27th, 2002 v0.03 -- Sped up s_mp_mul_high_digs by not computing the carries of the lower digits -- Fixed a bug where mp_set_int wouldn't zero the value first and set the used member. -- fixed a bug in s_mp_mul_high_digs where the limit placed on the result digits was not calculated properly -- fixed bugs in add/sub/mul/sqr_mod functions where if the modulus and dest were the same it wouldn't work -- fixed a bug in mp_mod and mp_mod_d concerning negative inputs -- mp_mul_d didn't preserve sign -- Many many many many fixes -- Works in LibTomCrypt now :-) -- Added iterations to the timing demos... more accurate. -- Tom needs a job. Dec 26th, 2002 v0.02 -- Fixed a few "slips" in the manual. This is "LibTomMath" afterall :-) -- Added mp_cmp_mag, mp_neg, mp_abs and mp_radix_size that were missing. -- Sped up the fast [comba] multipliers more [yahoo!] Dec 25th,2002 v0.01 -- Initial release. Gimme a break. -- Todo list, add details to manual [e.g. algorithms] more comments in code example programs
