Struct blsttc::SecretKeySet

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.

pub fn poly(&self) -> &Poly

Returns a reference to the polynomial

pub fn secret_key(&self) -> SecretKey

Returns the secret master key.

pub fn derive_child(&self, index: &[u8]) -> Self

Derives a child secret key set for a given index.

pub fn to_bytes(&self) -> Vec<u8>

Serializes to big endian bytes

pub fn from_bytes(bytes: Vec<u8>) -> Result<Self>

Deserializes from big endian bytes
