我在 Windows 上运行 uftp，在 qnx Rtos 上运行 uftpd。当我发送未加密的数据时，它对我来说很好。我正在使用以下命令发送未加密的数据。
UFTP: uftp -Y none -h sha1 -r 0.5:0.5:0.5 -t 20 -s 10 -M 230.4.4.1 -P
230.5.5.1 -p 32322 D:\FTPServer\automationbuild\options-350-19-
01B_7830_7835none.dat
UFTPD: "/usr/bin/uftpd", "uftpd", "-M",
(const char )m_puftpfiletransferparams->m_MulticastIp, "-p",
(const char )m_puftpfiletransferparams->m_iPort, "-D",
"/ram/tmp",NULL
它工作正常，我正在获取日志

我没有得到使它工作所需的其他东西。我是否需要在两边都添加 -k 或 -K ，如果我不添加它会不起作用吗？我的理解是，如果我不使用 -k 它将默认生成 512 位 rsa 密钥。
我没有得到任何帮助。请帮助我更好地理解它。
