A day early, fully tested with GCC 3.4.4 and ICC 8.0 [on an AMD64 and Prescott P4] … LibTomCrypt 1.03 has been <a href=download.html>released</a>. As to why this took so long, well just check out this sort of function <a href=http://libtomcrypt.com/der_encode_integer.png>[img]</a> or <a href=ecc_map.png>[img]</a> or <a href=invmod.png>[img]</a>. You can make the full 1370 page reference <a href=refman.pdf>manual</a> (<a href=refman.pdf.bz2>bz2 pdf</a>)with “make doxy” and see the size of the library for yourself [while admiring how small the compiled code is… ;-)].
