Variables ¶
var Altbn128 = &altbn128{}
Altbn128Inst is the instance for the altbn128 curve, with all of its functions.
var Bls12 = &bls12Curve{}
Bls12 is the instance for the bls12 curve, with all of its functions.
Functions ¶
func AltbnBlake2b ¶
AltbnBlake2b Hashes a message to a point on Altbn128 using Blake2b and try and increment The return value is the x,y affine coordinate pair.
func AltbnKeccak3 ¶
AltbnKeccak3 Hashes a message to a point on Altbn128 using Keccak3 and try and increment Keccak3 is only for compatability with Ethereum hashing. The return value is the x,y affine coordinate pair.
func AltbnSha3 ¶
AltbnSha3 Hashes a message to a point on Altbn128 using SHA3 and try and increment The return value is the x,y affine coordinate pair.
func EthereumSum256 ¶
EthereumSum256 returns the Keccak3-256 digest of the data. This is because Ethereum uses a non-standard hashing algo.
Types ¶
type CurveSystem ¶
type CurveSystem interface {
Name() string
MakeG1Point([]*big.Int, bool) (Point, bool)
MakeG2Point([]*big.Int, bool) (Point, bool)
UnmarshalG1([]byte) (Point, bool)
UnmarshalG2([]byte) (Point, bool)
UnmarshalGT([]byte) (PointT, bool)
GetG1() Point
GetG2() Point
GetGT() PointT
GetG1Infinity() Point
GetG2Infinity() Point
GetGTIdentity() PointT
HashToG1(message []byte) Point
GetG1Q() *big.Int
GetG1Order() *big.Int
Pair(Point, Point) (PointT, bool)
// Product of Pairings
PairingProduct([]Point, []Point) (PointT, bool)
// contains filtered or unexported methods
}
CurveSystem is a set of parameters and functions for a pairing based cryptosystem It has everything necessary to support all bgls functionality which we use.
type Point ¶
type Point interface {
Add(Point) (Point, bool)
Copy() Point
Equals(Point) bool
Marshal() []byte
MarshalUncompressed() []byte
Mul(*big.Int) Point
ToAffineCoords() []*big.Int
}
Point is a way to represent a point on G1 or G2, in the first two elliptic curves.
func AggregatePoints ¶
AggregatePoints takes the sum of points.
