libss is a Rust library for secret sharing.
WARNING: This implementation has not received any audit and is NOT ready for production use.
Overview
libss provides an impelmentation of shamir secret sharing over the field GF(2**8), supporting arbitrary size secrets with up to 255 shares.

This library comes with unit tests for each of the provided crates. Run the tests with:
To perform the benchmarks, run the following command:
Future Goals
- improve interpolation algorithm
- wrap Share struct into a SignedShare struct so integrity of shares can be verified with a public key
- implement Feldman Secret Sharing Scheme, a verifiable secret sharing scheme
- guarantee constant-time cryptographic operations
