Luke Parker	9b52cf4d20	Generalize out the FROST test for signing/signing with an offset ... Moves Schnorr signature tests from test_curve to the new test_schnorr, which is more a test_frost. Relevant to https://github.com/serai-dex/serai/issues/9.	2022-06-03 19:08:25 -04:00
Luke Parker	f8d127bf8a	Add FROST Ed25519 test vectors	2022-06-03 03:56:17 -04:00
Luke Parker	b4cd29f49a	Finish implementing FROST v5 ... Identity check for P256 and H4 was all that was needed.	2022-06-03 02:00:38 -04:00
Luke Parker	44452d9bfe	Verify being FROST v5 compliant ... No functional changes have been made to signing, with solely slight API changes being made. Technically not actually FROST v5 compatible, due to differing on zero checks and randomness, yet the vectors do confirm the core algorithm. For any valid FROST implementation, this will be interoperable if they can successfully communicate. For any devious FROST implementation, this will be fingerprintable, yet should still be valid. Relevant to https://github.com/serai-dex/serai/issues/9 as any curve can now specify vectors for itself and be tested against them. Moves the FROST testing curve from k256 to p256. Does not expose p256 despite being compliant. It's not at a point I'm happy with it, notably regarding hash to curve, and I'm not sure I care to support p256. If it has value to the larger FROST ecosystem...	2022-06-03 01:25:46 -04:00
