Dave Collins 08498b8b24 secp256k1: Avoid inversion in sig verify. ... This modifies signature verification to perform the final equality check in Jacobian projective space to avoid an extra expensive field inversion by taking advantage of the fact the R component of the signature can be converted to Jacobian projective space and compared directly so long as the two possible cases that arise from R being mod N and the original x coordinate used to create it being mod P. The following is a before and after comparison of verification of a typical signature: benchmark old ns/op new ns/op delta ----------------------------------------------------- BenchmarkSigVerify 189505 177147 -6.52% benchmark old allocs new allocs delta ----------------------------------------------------- BenchmarkSigVerify 34 34 +0.00% benchmark old bytes new bytes delta ----------------------------------------------------- BenchmarkSigVerify 1633 1633 +0.00%		2020-03-24 11:12:40 -05:00
