Felix Lange	5f7826270c	all: unify big.Int zero checks, use common/math in more places (#3716) ... * common/math: optimize PaddedBigBytes, use it more name old time/op new time/op delta PaddedBigBytes-8 71.1ns ± 5% 46.1ns ± 1% -35.15% (p=0.000 n=20+19) name old alloc/op new alloc/op delta PaddedBigBytes-8 48.0B ± 0% 32.0B ± 0% -33.33% (p=0.000 n=20+20) * all: unify big.Int zero checks Various checks were in use. This commit replaces them all with Int.Sign, which is cheaper and less code. eg templates: func before(x *big.Int) bool { return x.BitLen() == 0 } func after(x *big.Int) bool { return x.Sign() == 0 } func before(x *big.Int) bool { return x.BitLen() > 0 } func after(x *big.Int) bool { return x.Sign() != 0 } func before(x *big.Int) int { return x.Cmp(common.Big0) } func after(x *big.Int) int { return x.Sign() } * common/math, crypto/secp256k1: make ReadBits public in package math	8 years ago

Felix Lange	1b29aed128	crypto/secp256k1: verify recovery ID before calling libsecp256k1 ... The C library treats the recovery ID as trusted input and crashes the process for invalid values, so it needs to be verified before calling into C. This will inhibit the crash in #1983. Also remove VerifySignature because we don't use it.	9 years ago
