* Add dkg crate * Remove F_len and G_len They're generally no longer used. * Replace hash_to_vec with a provided method around associated type H: Digest Part of trying to minimize this trait so it can be moved elsewhere. Vec, which isn't std, may have been a blocker. * Encrypt secret shares within the FROST library Reduces requirements on callers in order to be correct. * Update usage of Zeroize within FROST * Inline functions in key_gen There was no reason to have them separated as they were. sign probably has the same statement available, yet that isn't the focus right now. * Add a ciphersuite package which provides hash_to_F * Set the Ciphersuite version to something valid * Have ed448 export Scalar/FieldElement/Point at the top level * Move FROST over to Ciphersuite * Correct usage of ff in ciphersuite * Correct documentation handling * Move Schnorr signatures to their own crate * Remove unused feature from schnorr * Fix Schnorr tests * Split DKG into a separate crate * Add serialize to Commitments and SecretShare Helper for buf = vec![]; .write(buf).unwrap(); buf * Move FROST over to the new dkg crate * Update Monero lib to latest FROST * Correct ethereum's usage of features * Add serialize to GeneratorProof * Add serialize helper function to FROST * Rename AddendumSerialize to WriteAddendum * Update processor * Slight fix to processor

# 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
|
|
11 is supported.
