parseHandshakeMessage method

@override CryptoPeerCapabilities parseHandshakeMessage(Map<String, dynamic> message)

Parses a handshake message from the remote peer.

Implementation

@override
CryptoPeerCapabilities parseHandshakeMessage(Map<String, dynamic> message) {
  final keyExchange = (message['keyExchange'] as List<dynamic>)
      .map((e) => _stringToKeyExchangeAlgorithm(e.toString()))
      .where((e) => e != null)
      .cast<KeyExchangeAlgorithm>()
      .toList();

  final asymmetric = (message['asymmetric'] as List<dynamic>)
      .map((e) => _stringToAlgorithm(e.toString()))
      .where((e) => e != null)
      .cast<CryptoAlgorithm>()
      .toList();

  final symmetric = (message['symmetric'] as List<dynamic>)
      .map((e) => _stringToAlgorithm(e.toString()))
      .where((e) => e != null)
      .cast<CryptoAlgorithm>()
      .toList();

  return CryptoPeerCapabilities(
    peerId: message['peerId'].toString(),
    keyExchange: keyExchange,
    asymmetric: asymmetric,
    symmetric: symmetric,
  );
