# Distributed Key Generation

A crate implementing a type for keys, presumably the result of a distributed key generation
protocol, and utilities from there.

This crate used to host implementations of distributed key generation protocols as well (hence the
name). Those have been smashed into their own crates, such as
[`dkg-musig`](https://docs.rs/dkg-musig) and [`dkg-pedpop`](https://docs.rs/dkg-pedpop)

Before being smashed, this crate was [audited by Cypher Stack in March 2023](

), culminating in commit [669d2dbffc1dafb82a09d9419ea182667115df06](
  https://github.com/serai-dex/serai/tree/669d2dbffc1dafb82a09d9419ea182667115df06
). Any subsequent changes have not undergone auditing.
Create a dedicated crate for the DKG (#141) * 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 2022-10-29 03:54:42 -05:00			`# Distributed Key Generation`

Smash dkg into dkg, dkg-[recovery, promote, musig, pedpop] promote and pedpop require dleq, which don't support no-std. All three should be moved outside the Serai repository, per #597, as none are planned for use and worth covering under our BBP. 2025-08-18 01:24:40 -04:00			`A crate implementing a type for keys, presumably the result of a distributed key generation`
