calculateSCC static method

  1. @visibleForTesting
DESedeSSC calculateSCC({
  1. required Uint8List RNDifd,
  2. required Uint8List RNDicc,
})

Calculates Send Sequence Counter (SCC) from RNDifd and RNDicc.

Implementation

@visibleForTesting
static DESedeSSC calculateSCC({  required final Uint8List RNDifd, required final Uint8List RNDicc }) {
  assert(RNDifd.length == nonceLen);
  assert(RNDicc.length == nonceLen);
  final int suffix = (nonceLen / 2).round();
  final ssc = Uint8List.fromList(RNDicc.sublist(suffix) + RNDifd.sublist(suffix));
  return DESedeSSC(ssc);
