Struct DirtyKeyInfo 

pub struct DirtyKeyInfo<E>
where
    E: Curve,
{
    pub curve: CurveName<E>,
    pub shared_public_key: NonZero<Point<E>>,
    pub public_shares: Vec<NonZero<Point<E>>>,
    pub vss_setup: Option<VssSetup<E>>,
    pub chain_code: Option<[u8; 32]>,
}

Public Key Info

Contains public information about the TSS key, including shared public key, commitments to secret shares and etc.

Fields

curve: CurveName<E>

Guard that ensures curve consistency for deseraization

shared_public_key: NonZero<Point<E>>

Public key corresponding to shared secret key. Corresponds to X in paper.

public_shares: Vec<NonZero<Point<E>>>

Public shares of all signers sharing the key

public_shares[i] corresponds to public share (or public commitment) of $\ith$ party.

vss_setup: Option<VssSetup<E>>

Verifiable secret sharing setup, present if key was generated using VSS scheme

chain_code: Option<[u8; 32]>

Available on crate feature hd-wallet only.

Chain code associated with the key, if HD wallets support was enabled

Implementations

impl<E> DirtyKeyInfo<E>

where E: Curve,

pub fn share_preimage(&self, j: u16) -> Option<NonZero<Scalar<E>>>

Returns share preimage associated with j-th signer

• For additive shares, share preimage is defined as j+1
• For VSS-shares, share preimage is scalar $I_j$ such that $x_j = F(I_j)$ where $F(x)$ is polynomial co-shared by the signers and $x_j$ is secret share of j-th signer

Note: if you have no idea what it is, probably you don’t need it.

impl<E> DirtyKeyInfo<E>

where E: Curve,

pub fn is_hd_wallet(&self) -> bool

Available on crate feature hd-wallet only.

Checks whether the key is HD-capable

pub fn extended_public_key(&self) -> Option<ExtendedPublicKey<E>>

Available on crate feature hd-wallet only.

Returns extended public key, if HD support was enabled

pub fn derive_child_public_key<Hd, ChildIndex>( &self, derivation_path: impl IntoIterator<Item = ChildIndex>, ) -> Result<ExtendedPublicKey<E>, HdError<<ChildIndex as TryInto<NonHardenedIndex>>::Error>>

where Hd: HdWallet<E>, NonHardenedIndex: TryFrom<ChildIndex>,

Available on crate feature hd-wallet only.

Derives child public key, if it’s HD key, using HdWallet algorithm
