Methods

add(Point other) → Point

Point addition: P+Q, complete, exception

affinePoint() → AffinePoint

Convert point to 2d xy affine point.

assertValidity() → Point

Checks if the point is valid and on-curve

copy() → Point

Make a copy of the point

double() → Point

Point doubling: P+P, complete formula.

equals(Point other) → bool

Equality check: compare points

mul(BigInt n, [bool safe = true]) → Point

Point scalar multiplication.

mulAddQUns(Point R, BigInt u1, BigInt u2) → Point

to private keys. Doesn't use Shamir trick Unsafe: do NOT use for stuff related

multiply(BigInt n) → Point

Aliases to compress code

negate() → Point

Flip point over y coord

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

ok() → Point

toHex([bool isCompressed = true]) → String

Encode point to hex string.

toRawBytes([bool isCompressed = true]) → Uint8List

Encode point to Uint8Array.

toString() → String

A string representation of this object.
