Crate dkg

A collection of implementations of various distributed key generation protocols. They all resolve into the provided Threshold types intended to enable their modularity. Additional utilities around them, such as promotion from one generator to another, are also provided.

Modules

• encryption
  Encryption types and utilities used to secure DKG messages.
• frost
  The distributed key generation protocol described in the FROST paper.
• promote
  Promote keys between ciphersuites.
• teststests
  Tests for application-provided curves and algorithms.

Structs

• Participant
  The ID of a participant, defined as a non-zero u16.
• ThresholdCore
  Keys and verification shares generated by a DKG. Called core as they’re expected to be wrapped into an Arc before usage in various operations.
• ThresholdKeys
  Threshold keys usable for signing.
• ThresholdParams
  Parameters for a multisig.
• ThresholdView
  View of keys passed to algorithm implementations.

Enums

• DkgError
  Various errors possible during key generation/signing.

Functions

• lagrange
  Calculate the lagrange coefficient for a signing set.
