encode method

@override Uint8List encode()

Encode into bytes.

Implementation

@override
Uint8List encode() {
  final bytes = <int>[];

  // The "openssh-key-v1" null terminated

  // ignore: cascade_invocations
  bytes
    ..addAll(latin1.encode(magicVersionId))
    ..add(0); // null terminate

  // Values with a length before them:

  // ignore: cascade_invocations
  bytes.addAll(BinaryLengthValue.encode([
    BinaryLengthValue.fromString(cipherName),
    BinaryLengthValue.fromString(kdfName),
    BinaryLengthValue(kdf)
  ]));

  // ignore: cascade_invocations
  bytes.addAll(Uint8List.fromList([0, 0, 0, 1])); // number of keys: no length

  // Keys: also values with a length before them

  // ignore: cascade_invocations
  bytes.addAll(BinaryLengthValue.encode([
    BinaryLengthValue(publicKeyBytes),
    BinaryLengthValue(privateKeyBytes)
  ]));

  final result = Uint8List.fromList(bytes);

  return result;
}
