无法通过套接字编程传输AES加密文件

Question

我尝试通过套接字编程传输AES加密文件，但是当我指定文件路径时，它会出现以下异常，当我尝试传输未加密的文件时，它可以正常工作。

java.io.FileNotFoundException: salt.ecn (The system cannot find the file specified)
    at java.io.FileInputStream.open0(Native Method)
    at java.io.FileInputStream.open(FileInputStream.java:195)
    at java.io.FileInputStream.<init>(FileInputStream.java:138)
    at java.io.FileInputStream.<init>(FileInputStream.java:93)
    at nigam.Front.server(Front.java:52)
    at nigam.Front$7.run(Front.java:621)

代码：

public class SocketFileExample {
    static void server() throws IOException {
        ServerSocket ss = new ServerSocket(3434);
        Socket socket = ss.accept();
        InputStream in = new FileInputStream("salt.ecn");
        OutputStream out = socket.getOutputStream();
        copy(in, out);
        out.close();
        in.close();
    }

    static void client() throws IOException {
        Socket socket = new Socket("localhost", 3434);
        InputStream in = socket.getInputStream();
        OutputStream out = new FileOutputStream("C:\\Users\\SIDDHARTH\\Documents\\NetBeansProjects\\Nigam\\salt.ecn");
        copy(in, out);
        out.close();
        in.close();
    }

    static void copy(InputStream in, OutputStream out) throws IOException {
        byte[] buf = new byte[8192];
        int len = 0;
        while ((len = in.read(buf)) != -1) {
            out.write(buf, 0, len);
        }
    }

    public static void main(String[] args) throws IOException {
        new Thread() {
            public void run() {
                try {
                    server();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }.start();

        client();
    }
}
