Modules

error

Crypto errors.

poly

Utilities for distributed key generation: uni- and bivariate polynomials and commitments.

serde_impl

Serialization and deserialization implementations for group and field elements.

Structs

Ciphertext

An encrypted message.

DecryptionShare

A decryption share. A threshold of decryption shares can be used to decrypt a message.

PEngine

PublicKey

A public key.

PublicKeySet

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

PublicKeyShare

A public key share.

SecretKey

A secret key; wraps a single prime field element. The field element is heap allocated to avoid any stack copying that result when passing SecretKeys between stack frames.

SecretKeySet

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

SecretKeyShare

A secret key share.

Signature

A signature.

SignatureShare

A signature share.

Constants

PK_SIZE

The size of a key’s representation in bytes.

SIG_SIZE

The size of a signature’s representation in bytes.

Traits

IntoFr

A conversion into an element of the field Fr.

Functions

hash_g2

Returns a hash of the given message in G2.
