Struct phron_finality::abft::crypto::Keychain

pub struct Keychain {
    id: NodeIndex,
    authority_pen: AuthorityPen,
    authority_verifier: AuthorityVerifier,
}

Keychain combines an AuthorityPen and AuthorityVerifier into one object implementing the AlephBFT MultiKeychain trait.

Fields

id: NodeIndex

authority_pen: AuthorityPen

authority_verifier: AuthorityVerifier

Implementations

impl Keychain

pub fn new( id: NodeIndex, authority_verifier: AuthorityVerifier, authority_pen: AuthorityPen ) -> Self

Constructs a new keychain from a signing contraption and verifier, with the specified node index.

fn index(&self) -> NodeIndex

fn node_count(&self) -> NodeCount

fn sign(&self, msg: &[u8]) -> Signature

fn verify<I: Into<NodeIndex>>( &self, msg: &[u8], sgn: &Signature, index: I ) -> bool

fn is_complete(&self, msg: &[u8], partial: &SignatureSet<Signature>) -> bool

Trait Implementations

impl Clone for Keychain

fn clone(&self) -> Keychain

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Index for Keychain

fn index(&self) -> NodeIndex

impl Index for Keychain

fn index(&self) -> NodeIndex

impl Keychain for Keychain

type Signature = Signature

fn node_count(&self) -> NodeCount

Returns the total number of known public keys.

fn sign<'life0, 'life1, 'async_trait>( &'life0 self, msg: &'life1 [u8] ) -> Pin<Box<dyn Future<Output = Signature> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Signs a message msg.

fn verify(&self, msg: &[u8], sgn: &Signature, index: NodeIndex) -> bool

Verifies whether a node with index correctly signed the message msg. Should always return false for indices outside the node range.

type Signature = Signature

fn node_count(&self) -> NodeCount

Returns the total number of known public keys.

fn sign<'life0, 'life1, 'async_trait>( &'life0 self, msg: &'life1 [u8] ) -> Pin<Box<dyn Future<Output = Signature> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Signs a message msg.

fn verify(&self, msg: &[u8], sgn: &Signature, index: NodeIndex) -> bool

Verifies whether a node with index correctly signed the message msg. Should always return false for indices outside the node range.

impl MultiKeychain for Keychain

type PartialMultisignature = SignatureSet<Signature>

fn bootstrap_multi( &self, signature: &Signature, index: NodeIndex ) -> Self::PartialMultisignature

fn is_complete(&self, msg: &[u8], partial: &Self::PartialMultisignature) -> bool

Checks if enough signatures have beed added.
