Wrong checksum

Hello, I have the same problem with https://github.com/sshnet/SSH.NET/issues/212
with sourceforge.net
but WinCSP works correct
Local sha256 is diff with server sha256

private static void HandleKeyEvent(object sender, AuthenticationPromptEventArgs e)
        {
            foreach (AuthenticationPrompt prompt in e.Prompts)
            {
                if (prompt.Request.IndexOf("Password:", StringComparison.InvariantCultureIgnoreCase) != -1)
                {
                    prompt.Response = "anypass";
                }
            }
        }
  KeyboardInteractiveAuthenticationMethod keybAuth = new KeyboardInteractiveAuthenticationMethod("jjjj");
            keybAuth.AuthenticationPrompt += new EventHandler<AuthenticationPromptEventArgs>(HandleKeyEvent);
            ConnectionInfo conInfo = new ConnectionInfo("frs.sourceforge.net", 22, "iikk", keybAuth);
            using (var sftp = new SftpClient(conInfo))
            {
                sftp.Connect();
 using (FileStream fs = new FileStream(zip_path, FileMode.Open))
                {
                          sftp.UploadFile(fs, "file.zip");
                }
}

从提供的 SftpClient.UploadFile 调用开始，跟踪 SSH.NET 如何处理上传的文件，并将本地存档的校验和与服务器结果进行比较。完成的标准是重现不匹配问题并确定已确认的原因，或记录为何无法处理该报告。
