Constructors

EDPoint({required CurveED curve, required BigInt x, required BigInt y, required BigInt z, required BigInt t, BigInt? order, bool generator = false})

Constructor for creating an EDPoint with explicit coordinates and optional parameters.

EDPoint.fromBytes({required CurveED curve, required List<int> data, BigInt? order})

Factory constructor to create an EDPoint from a byte representation.

factory

EDPoint.infinity({required CurveED curve})

A factory constructor to create an infinity point on an Edwards curve.

Properties

curve ↔ CurveED

The Edwards curve associated with this point.

getter/setter pair, override-getter

generator ↔ bool

Indicates if this point is a generator point.

getter/setter pair

hashCode → int

Calculates the hash code for the Edwards curve point.

no setter, override

isInfinity → bool

Checks if the Edwards curve point represents the point at infinity.

no setter, override

order ↔ BigInt?

The order of the point (null if not set).

getter/setter pair, override-getter

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

x → BigInt

Get the x-coordinate of the Edwards curve point.

no setter, override

y → BigInt

Get the y-coordinate of the Edwards curve point.

no setter, override

Methods

doublePoint() → EDPoint

Double an Edwards curve point.

override

getCoords() → List<BigInt>

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

scale() → EDPoint

Scale the Edwards curve point.

toBytes([EncodeType encodeType = EncodeType.comprossed]) → List<int>

Converts the elliptic curve point to a byte array with the specified encoding type. The default encoding type is 'compressed'.

inherited

toHex([EncodeType encodeType = EncodeType.comprossed]) → String

Encodes the elliptic curve point as a hexadecimal string with the specified encoding type. The default encoding type is 'compressed'.

inherited

toString() → String

A string representation of this object.

Operators

operator *(BigInt other) → EDPoint

Multiply an Edwards curve point by a scalar.

override

operator +(AbstractPoint other) → EDPoint

Addition operator for two Edwards curve points.

override

operator ==(Object other) → bool

Equality operator for comparing two Edwards curve points.

override

operator unary-() → EDPoint

Negation operator for an Edwards curve point.
