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. Currently, version 11 is supported.

This library was audited by Cypher Stack in March 2023, culminating in commit 669d2dbffc. While this 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.
