secp256k1 bindings for Go

General info

The Go API mirrors the API of the C implementation. Therefore, please consult c-secp256k1/include/secp256k1.h for documentation. Going forward I plan to implement a new API that is more aligned with the APIs from Go's standard lib crypto packages. Then, it makes more sense to add a standalone documentation, and hopefully breaking changes in the C implementation can be abstracted away.

How to get and build

go get -d github.com/toxeus/go-secp256k1
cd $GOPATH/src/github.com/toxeus/go-secp256k1
git submodule update --init # not needed for Go >= 1.6
cd c-secp256k1
./autogen.sh && ./configure && make
cd ..
go install

How to update

cd $GOPATH/src/github.com/toxeus/go-secp256k1
git submodule update
cd c-secp256k1
make distclean && ./autogen.sh && ./configure && make
cd ..
go clean && go install
