Modules
Crypto errors.
Utilities for distributed key generation: uni- and bivariate polynomials and commitments.
Serialization and deserialization implementations for group and field elements.
Structs
An encrypted message.
A decryption share. A threshold of decryption shares can be used to decrypt a message.
Represents an element of the scalar field $\mathbb{F}_q$ of the BLS12-381 elliptic
curve construction.
This is an element of $\mathbb{G}_1$ represented in the affine coordinate space.
It is ideal to keep elements in this representation to reduce memory usage and
improve performance through the use of mixed curve model arithmetic.
This is an element of $\mathbb{G}_1$ represented in the projective coordinate space.
This is an element of $\mathbb{G}_2$ represented in the affine coordinate space.
It is ideal to keep elements in this representation to reduce memory usage and
improve performance through the use of mixed curve model arithmetic.
This is an element of $\mathbb{G}_2$ represented in the projective coordinate space.
Bls12-381 engine
A public key.
A public key and an associated set of public key shares.
A public key share.
A secret key; wraps a single prime field element. The field element is
heap allocated to avoid any stack copying that result when passing
SecretKey
s between stack frames.A secret key and an associated set of secret key shares.
A secret key share.
A signature.
A signature share.
Constants
The domain separator tag
The size of a key’s representation in bytes.
The size of a signature’s representation in bytes.
The size of a secret key’s representation in bytes.
Traits
A conversion into an element of the field
