我在使用 tls 和 psk 的 spongycastle 实现时遇到问题。

我从网络服务中获得一个 psk 并尝试连接到网络服务器。在我的HttpTransportLayer课堂上，我创建了一个带有服务器地址和端口的套接字。然后我创建一个TLSIdentity获取sessionIdentifier和共享密钥。

try {
    socket = new Socket(hostAddress, port);
}catch(UnknownHostException e){
    e.printStackTrace();
}

TlsPSKIdentity identity = new BcTlsPSKIdentity(sessionID.getBytes("UTF-8"), Util.hexStringToByteArray(psk));
BcPSKTlsClient pskTlsClient = new BcPSKTlsClient(identity);

this.tlsClientProtocol = new TlsClientProtocol(socket.getInputStream(), socket.getOutputStream());
this.tlsClientProtocol.connect(pskTlsClient);

outputStream = tlsClientProtocol.getOutputStream();

当我尝试连接服务器时出现异常。有谁知道如何解决这个问题？非常感谢！
