finite_field_math

Pure Dart GF(2^m) Galois field arithmetic for symbol sizes 2 <= m <= 16.

Usage

import 'package:finite_field_math/finite_field_math.dart';

final finiteField = FiniteField(
  symbolSizeInBits: 8,
  primitivePolynomial: 0x11D,
  primitiveElement: 2,
);

final sum = finiteField.add(0x53, 0xCA);
final product = finiteField.multiply(0x53, 0xCA);

Features

• Independent field instances (no process-wide mutable tables)
• Log/exp table based multiply/divide for efficient arithmetic
• Validated configuration: symbol size, primitive polynomial, primitive element
