pad static method

Uint8List pad(
  1. Uint8List bytes,
  2. int blockSizeBytes
)

PKCS7 padding before AES-CBC encryption.

Implementation

static Uint8List pad(final Uint8List bytes, final int blockSizeBytes) {
  final int padLength = blockSizeBytes - (bytes.length % blockSizeBytes);
  final Uint8List padded = Uint8List(bytes.length + padLength)
    ..setAll(0, bytes);
  PKCS7Padding().addPadding(padded, bytes.length);
  return padded;
}
