Struct SecretShare 

pub struct SecretShare<S: CurveScalar> {
    pub index: u32,
    /* private fields */
}

A secret share from DKG

Security

This struct holds secret key material. It implements ZeroizeOnDrop to ensure the scalar is zeroed when the share goes out of scope.

Fields

index: u32

Shareholder index (1-indexed, as per Shamir convention)

Implementations

impl<S: CurveScalar> SecretShare<S>

pub fn new(index: u32, scalar: S) -> Result<Self, Error>

Construct a share.

Errors

Error::InvalidIndex if index is 0 — Shamir indices are 1-indexed, and index 0 is the secret itself. This returns rather than panicking: a node parsing an index off the wire must not be abortable by a peer.

pub fn scalar(&self) -> &S

Access the secret scalar (use sparingly, avoid logging/debugging)

pub fn public_share<P: CurvePoint<Scalar = S>>(&self) -> P

Derive public key share y_i = g^{x_i}

Trait Implementations

impl<S: Clone + CurveScalar> Clone for SecretShare<S>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<S: CurveScalar> Debug for SecretShare<S>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<S: CurveScalar> Drop for SecretShare<S>

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
