wordsToBytesChunk static method

List<int> wordsToBytesChunk(
  1. String word1,
  2. String word2,
  3. String word3,
  4. MnemonicWordsList wordsList, {
  5. Endian endian = Endian.big,
})

Converts a sequence of three words into a byte chunk using a specified word list.

Implementation

static List<int> wordsToBytesChunk(
  String word1,
  String word2,
  String word3,
  MnemonicWordsList wordsList, {
  Endian endian = Endian.big,
}) {
  final n = wordsList.length();
  final word1Idx = wordsList.getWordIdx(word1);
  final word2Idx = wordsList.getWordIdx(word2) % n;
  final word3Idx = wordsList.getWordIdx(word3) % n;

  final intChunk =
      word1Idx +
      (n * ((word2Idx - word1Idx) % n)) +
      (n * n * ((word3Idx - word2Idx) % n));

  return IntUtils.toBytes(intChunk, byteOrder: endian, length: 4);
