README

secp256k1-go

golang secp256k1 library

Implements cryptographic operations for the secp256k1 ECDSA curve used by Bitcoin.

Installing

GMP library headers are required to build. On Debian-based systems, the package is called libgmp-dev.

sudo apt-get install libgmp-dev

Now compiles with cgo!

Test

To run tests do

go tests

func GeneratePubKey

func GeneratePubKey(seckey []byte) ([]byte, error)

func RecoverPubkey

func RecoverPubkey(msg []byte, sig []byte) ([]byte, error)

recovers a public key from the signature
