Struct threshold_crypto::SecretKeyShare

pub struct SecretKeyShare(_);

A secret key share.

Implementations

impl SecretKeyShare

pub fn from_mut(fr: &mut Fr) -> Self

Creates a new SecretKeyShare from a mutable reference to a field element. This constructor takes a reference to avoid any unnecessary stack copying/moving of secrets field elements. The field element will be copied bytewise onto the heap, the resulting Box is stored in the SecretKey which is then wrapped in a SecretKeyShare.

WARNING this constructor will overwrite the pointed to Fr element with zeros once it has been copied into a new SecretKeyShare.

pub fn public_key_share(&self) -> PublicKeyShare

Returns the matching public key share.

pub fn sign_g2<H: Into<G2Affine>>(&self, hash: H) -> SignatureShare

Signs the given element of G2.

pub fn sign<M: AsRef<[u8]>>(&self, msg: M) -> SignatureShare

Signs the given message.

pub fn decrypt_share(&self, ct: &Ciphertext) -> Option<DecryptionShare>

Returns a decryption share, or None, if the ciphertext isn’t valid.

pub fn decrypt_share_no_verify(&self, ct: &Ciphertext) -> DecryptionShare

Returns a decryption share, without validating the ciphertext.

pub fn reveal(&self) -> String

Generates a non-redacted debug string. This method differs from the Debug implementation in that it does leak the secret prime field element.

Trait Implementations

impl Clone for SecretKeyShare

fn clone(&self) -> SecretKeyShare

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SecretKeyShare

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

Formats the value using the given formatter.

impl Default for SecretKeyShare

fn default() -> SecretKeyShare

Returns the “default value” for a type.

impl PartialEq<SecretKeyShare> for SecretKeyShare

fn eq(&self, other: &SecretKeyShare) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Rand for SecretKeyShare

fn rand<__R: Rng>(__rng: &mut __R) -> Self

Generates a random instance of this type using the specified source of randomness.
