isxsecp256k1

Documentation

Overview

isxsecp256k1 provides a wrapper around the secp256k1 package from dcrec --which is an actively maintained codebase built from btcd.

Since Ethereum uses secp256k1 in special ways, this package exists to encapsulate the special ways so that it is easier to use the secp256k1 code in the 'right way.'

Sign and Recover are constructed from the secp256k1 author's advice: https://github.com/decred/dcrd/issues/2889, https://go.dev/play/p/gIbvbly7n9h
