indy-bls 0.1.0

Python wrapper for the Indy BLS signatures implementation

indy-bls-wrapper-python

A Python wrapper for Hyperledger Indy BLS Signatures Rust as used by Hyperledger Indy Node.

This package implements a version of the BLS signature scheme. The implementation doesn't match up with the BLS signatures specification at the IETF. It uses the BN254 curve defined here (sometimes called BN254N), and should not to be confused with the one used in Ethereum.

This package is NOT recommended for new projects. It would be preferable to use a BLS signatures implementation based on the IETF draft, on a curve with a stronger security estimation (such as BLS12-381).

Installation

The package may be installed by using:

pip install indy_bls

No additional dependencies are required for installation. Python 3.6 and higher are currently supported.

Building

The primary build dependency is the Rust crate: Hyperledger Indy BLS Signatures Rust, which requires a Rust compiler toolchain. Python packaging requires setuptools and wheel.
