FROST (Flexible Round-Optimised Schnorr Threshold signatures) Rerandomized

Base traits and types in Rust that implement 'Two-Round Threshold Schnorr Signatures with FROST' generically for frost-core::Ciphersuite implementations, with support for Zcash-compatible RedDSA re-randomized signatures.

Status ⚠

The FROST specification is not yet finalized, and this codebase has not yet been audited or released. The APIs and types in frost-rerandomized are subject to change.

Usage

frost-rerandomized is similar to frost-core, but provides different sign() and aggregate() functions adding support for re-randomized signatures. End-users should not use frost-rerandomized if they want to sign and verify signatures, they should use the crate specific to their ciphersuite/curve parameters that uses frost-rerandomized as a dependency, such as reddsa.

Example

See ciphersuite-specific modules, e.g. the ones in reddsa.
