| 09:35:00 | gmaxwell: | Epic ECC fail, some random PHPECC code linked in #bitcoin |
| 09:35:26 | gmaxwell: | implements a generic point addition that should work on Weierstrass curves. |
| 09:35:41 | gmaxwell: | starts off with this gem: |
| 09:35:59 | gmaxwell: | if (gmp_Utils::gmp_mod2(gmp_cmp($p1->x, $p2->x), $p1->curve->getPrime()) == 0) { |
| 09:36:03 | gmaxwell: | if (gmp_Utils::gmp_mod2(gmp_add($p1->y, $p2->y), $p1->curve->getPrime()) == 0) { |
| 09:36:12 | gmaxwell: | cmp()% Fp wtf?! |
| 09:38:25 | dsnrk: | at the risk of revealing my complete lack of knowledge with EC; what's the end result? |
| 09:38:38 | gmaxwell: | I think its actually harmless by chance but its still a WTF |
| 09:39:41 | otoburb_: | otoburb_ is now known as Guest98694 |
| 09:40:27 | gmaxwell: | dsnrk: what it's trying to do is tell if p1 == p2 or if p1 == -p2 in the first case the x,y will match, in the latter case x will match but the sum of the y's mod Fp will be 0. |
