secp256k1

Crystal bindings for the Bitcoin Core implementation of secp256k1 library.

Prerequisites

Applications that using these bindings must have access to the installed libsecp256k1 library.

Since these bindings are designed for the Bitcoin Core implementation, there is no guarantee of working with others.

Installation

1. Add the dependency to your shard.yml:

   dependencies:
     secp256k1:
       github: qualterz/secp256k1.cr

2. Run shards install

Usage

require "secp256k1"

• Native bindings. See native examples.
• Crystal wrapper. See wrapper examples.

Documentation

In case of using native bindings, original examples and documentation can be used for reference.

Deprecated library functions will not be wrapped, so if there is need to use them, they can be used natively.

Development

The bindings are generated automatically by executing make generate_lib shell command.

The libgen is used as a bindings generator.
