kyber-bls12381

Kyber wrapper around kilic/bls12381 library.

Note: GT does not fully support the kyber.Point interface yet.

Previous library

This repository is the successor of the previous library bls12381 which was a complete fork of the upstream library.

Functions

func DefaultDomainG1 added in v0.3.0 

func DefaultDomainG1() []byte

func DefaultDomainG2 added in v0.3.0 

func DefaultDomainG2() []byte

func NewBLS12381Suite 

func NewBLS12381Suite() pairing.Suite

NewBLS12381Suite is the same as calling NewBLS12381SuiteWithDST(nil, nil): it uses the default domain separation tags for its Hash To Curve functions.

func NewBLS12381SuiteWithDST added in v0.3.0 

func NewBLS12381SuiteWithDST(DomainG1, DomainG2 []byte) pairing.Suite

NewBLS12381SuiteWithDST allows you to set your own domain separation tags to be used by the Hash To Curve functions. Since the DST shouldn't be 0 len, if you provide nil or a 0 len byte array, it will use the RFC default values.

func NewGroupG1 

func NewGroupG1(dst ...byte) kyber.Group

func NewGroupG2 

func NewGroupG2(dst ...byte) kyber.Group

func NewGroupGT 

func NewGroupGT() kyber.Group

Types

type GroupChecker 

type GroupChecker interface {
	kyber.Point
	IsInCorrectGroup() bool
}

GroupChecker allows to verify if a Point is in the correct group or not. For curves which don't have a prime order, we need to only consider the points lying in the subgroup of prime order. That check returns true if the point is correct or not.
