Struct threshold_crypto::SecretKeySet

pub struct SecretKeySet { /* fields omitted */ }

A secret key and an associated set of secret key shares.

Methods

impl SecretKeySet

pub fn random<R: Rng>(threshold: usize, rng: &mut R) -> Self

Creates a set of secret key shares, where any threshold + 1 of them can collaboratively sign and decrypt. This constructor is identical to the SecretKeySet::try_random() in every way except that this constructor panics if the other returns an error.

Panic

Panics if the threshold is too large for the coefficients to fit into a Vec.

pub fn try_random<R: Rng>(threshold: usize, rng: &mut R) -> Result<Self>

Creates a set of secret key shares, where any threshold + 1 of them can collaboratively sign and decrypt. This constructor is identical to the SecretKeySet::random() in every way except that this constructor returns an Err where the random would panic.

pub fn threshold(&self) -> usize

Returns the threshold t: any set of t + 1 signature shares can be combined into a full signature.

pub fn secret_key_share<T: IntoFr>(&self, i: T) -> SecretKeyShare

Returns the i-th secret key share.

pub fn public_keys(&self) -> PublicKeySet

Returns the corresponding public key set. That information can be shared publicly.
