PyQuorum

Cryptographic library for secret sharing and key management, powered by Rust

Installation

pip install pyquorum

Quick Start

from pyquorum import ShamirScheme, BlakleyScheme, generate_key

k=3 # threshold for combine
n=4 # number of total shares
key = generate_key()
Scheme = ShamirScheme(k, n) # BlakleyScheme(k, n)
shares = Scheme.split(key)
combine = Scheme.combine(shares)

Security

This library does:

• generate key
• split secret
• combine secret

What it doesn't:

• replace encryption packages like cryptography, pyserpent and etc

WARNING - This library is in active development (0.x.x). It has not undergone a professional security audit and contains known vulnerabilities. Do not use in production.

You can review known vulnerabilities in SECURITY_ISSUES_TRACKER.md

If you found a security issue, please refer to SECURITY.md

Roadmap to v1.0.0

• - Shamir Scheme
• - Blakley Scheme
• - Additive Scheme
• - HKDF Key Derivation
• - Threshold ECDSA

Support

If you find this package usefull, you can star repo on github
