HiveAesCipher constructor

HiveAesCipher(
  1. List<int> key
)

Create a cipher with the given key.

Implementation

HiveAesCipher(List<int> key) {
  if (key.length != 32 || key.any((it) => it < 0 || it > 255)) {
    throw ArgumentError(
        'The encryption key has to be a 32 byte (256 bit) array.');
  }

  var keyBytes = Uint8List.fromList(key);
  _cipher = AesCbcPkcs7(keyBytes);
  _keyCrc = Crc32.compute(sha256.convert(keyBytes).bytes as Uint8List);
}
