feldman_vss	Fast Multiparty Threshold ECDSA with Fast Trustless Setup In a verifiable secret sharing scheme, auxiliary information is published that allows players to check that their shares are consistent and define a unique secret. Feldman’s VSS is an extension of Shamir secret sharing in which the dealer also publishes vi=gai inGforalli∈[1,t]andv0=gσ inG. If the check does not hold for any player, it raises a complaint and the protocol terminates. Note that this is different than the way Feldman VSS was originally presented as it assumed an honest majority and could recover if a dishonest player raised a complaint. However, since we assume dishonest majority in this paper, the protocol will abort if a complaint is raised.
keys	Keys to the kingdom Schnorr signatures on the 2-tortsion free subgroup of ed25519, as provided by the Ristretto point compression.s
signature	A Rust implementation of Schnorr signing
threshold

BatchVerifier	Batch signature verifier for use with `Signature::verify_batched`.
Multimessage	MuSig multimessage context
Signer	Entry point to multi-party signing protocol.
SignerAwaitingCommitments	State of the party when awaiting nonce commitments from other parties.
SignerAwaitingPrecommitments	State of the party when awaiting nonce precommitments from other parties.
SignerAwaitingShares	State of the party when awaiting signature shares from other parties.
SigningContext	A Signing Context Provides an abstraction for signature protocol Merlin Transcript
SingleVerifier	Single signature verifier that implements batching interface.

Internal errors. Most application-level developers will likely not need to pay any attention to these.

BatchVerification	Trait for a batch verification of signatures. If you are only verifying signatures, without other proofs, you can use concrete implementation `BatchVerifier` without rolling out your own.
MuSigContext	The context for signing - can either be a Multikey or Multimessage context.
Multisignature	Extension trait for `schnorr::Signature`.

Perform a Diffie-Hellman key agreement to produce a SharedSecret.

Alias type for a shared secret after ECDH
