libsecp256k1-rb

A Ruby FFI binding for bitcoin's secp256k1 library, superseding ruby-bitcoin-secp256k1.

In order to use this gem, bitcoins's secp256k1 dynamic library (libsecp256k1.dylib) must be discoverable.

Use Homebrew on macOS or apt on Debian/Ubuntu:

brew install secp256k1
apt install libsecp256k1-dev gcc

Or build locally:

git submodule update --init --recursive
./make.sh
./test.sh

gem i libsecp256k1

Then require "secp256k1" in your source code.

You need to set C_INCLUDE_PATH and LD_LIBRARY_PATH (or SECP256K1_LIB_PATH) environment variables, see test.sh for usage.

Check test for examples.
