github.com/btcsuite/btcd/btcec/v2
Package btcec implements support for the elliptic curves needed for bitcoin. Bitcoin uses elliptic curve cryptography using koblitz curves (specifically secp256k1) for cryptographic functions. See http://www.secg.org/collateral/sec2_final.pdf for details on the standard. This package provides the data structures and functions implementing the crypto/elliptic Curve interface in order to permit using these curves with the standard crypto/ecdsa package provided with go. Helper functionality is provided to parse signatures and public keys from standard formats. It was designed for use with btcd, but should be general enough for other uses of elliptic curve crypto. It was originally based on some initial work by ThePiachu, but has significantly diverged since then.
Readme
Package btcec implements elliptic curve cryptography needed for working with Bitcoin (secp256k1 only for now). It is designed so that it may be used with the standard crypto/ecdsa packages provided with go. A comprehensive suite of test is provided to ensure proper functionality. Package btcec was originally based on work from ThePiachu which is licensed under the same terms as Go, but it has signficantly diverged since then. The btcsuite developers original is licensed under the liberal ISC license.
Although this package was primarily written for btcd, it has intentionally been designed so it can be used as a standalone package for any projects needing to use secp256k1 elliptic curve cryptography.
$ go install -u -v github.com/btcsuite/btcd/btcec/v2
Sign Message
Demonstrates signing a message with a secp256k1 private key that is first
parsed form raw bytes and serializing the generated signature.
Verify Signature
Demonstrates verifying a secp256k1 signature against a public key that is
first parsed from raw bytes. The signature is also parsed from raw bytes.
Package btcec is licensed under the copyfree ISC License except for btcec.go and btcec_test.go which is under the same license as Go.
