btcec: convert package into go module, alias to dcrec In this commit, we turn the package into a new Go module (version 2), and then port over the current set of types and functions to mainly alias to the more optimized and maintained dcrec variant. Taking a look at the benchmarks, most operations other than normalization (which IIRC is a bit slower now due to constant time fixes) enjoy some nice speeds up: ``` benchcmp is deprecated in favor of benchstat: https://pkg.go.dev/golang.org/x/perf/cmd/benchstat benchmark old ns/op new ns/op delta BenchmarkAddJacobian-8 464 328 -29.20% BenchmarkAddJacobianNotZOne-8 1138 372 -67.27% BenchmarkScalarBaseMult-8 47336 31531 -33.39% BenchmarkScalarBaseMultLarge-8 42465 32057 -24.51% BenchmarkScalarMult-8 123355 117579 -4.68% BenchmarkNAF-8 582 168 -71.12% BenchmarkSigVerify-8 175414 120794 -31.14% BenchmarkFieldNormalize-8 23.8 24.4 +2.39% BenchmarkParseCompressedPubKey-8 24282 10907 -55.08% ``` 2021-11-18 18:25:56 -08:00			`module github.com/btcsuite/btcd/btcec/v2`

btcec/v2: create new ecdsa package In this commit, we create a new package to house the ECDSA-specific logic in the new `btcec/v2` pacakge. Thsi c hange is meant to mirror the structure of the `dcrec` package, as we'll soon slot in our own custom BIP-340 implementation. 2021-12-02 18:33:04 -08:00
