使用AES传输大文件

Question

我想在服务器和客户端之间传输一个大文件，我知道如何做到这一点:对于客户端，代码如下:

OutputStream output = sk.getOutputStream();     
    FileInputStream fileInputStream = new FileInputStream(file);
    byte[] buffer = new byte[1024*1024];
    int bytesRead = 0;
    while((bytesRead = fileInputStream.read(buffer))>0)
    {
        output.write(buffer,0,bytesRead);
    }
    fileInputStream.close();

服务器端:

InputStream input = sk.getInputStream();
    file = new File(filename);
    FileOutputStream out = new FileOutputStream(file);
    byte[] buffer = new byte[1024*1024];
    int bytesReceived = 0;
    while((bytesReceived = input.read(buffer))>0) {
        out.write(buffer,0,bytesReceived);
        System.out.println(bytesReceived);
        break;
    }

现在的问题是，服务器和客户端都同意使用128位AES密钥，所以我想充分利用会话密钥来保证文件传输过程的安全。我的问题是，我可以在哪里插入AES加密过程在我的客户端和服务器?谢谢你！

我认为您可以使用javax.crypto.CipherInputStream/javax.crypto.CipherOutputStream。使用示例http://www.flexiprovider.de/examples/ExampleCrypt.html
