# Modular FROST

A modular implementation of FROST for any curve with a ff/group API.
Additionally, custom algorithms may be specified so any signature reducible to
Schnorr-like may be used with FROST.

A Schnorr algorithm is provided, of the form (R, s) where `s = r + cx`, which
allows specifying the challenge format. This is intended to easily allow
integrating with existing systems.

This library offers ciphersuites compatible with the
[IETF draft](https://github.com/cfrg/draft-irtf-cfrg-frost). Currently, version
15 is supported.

This library was

culminating in commit
[669d2dbffc1dafb82a09d9419ea182667115df06](https://github.com/serai-dex/serai/tree/669d2dbffc1dafb82a09d9419ea182667115df06).
Any subsequent changes have not undergone auditing. While this audit included
FROST's definition of Ed448, the underlying Ed448 ciphersuite (offered by the
ciphersuite crate) was not audited, nor was the minimal-ed448 crate implementing
the curve itself.
Rename FROST's official package name and update documentation 2022-06-19 09:21:22 +00:00			`# Modular FROST`
Initial commit Combines the existing frost-rs, dalek-ff-group, and monero-rs repos into a monorepo. Makes tweaks necessary as needed. Replaces RedDSA (which was going to be stubbed out into a new folder for now) with an offset system that voids its need and allows stealth addresses with CLSAG. 2022-04-22 01:36:18 +00:00
