将参数传递到控制台程序steghide [英] Pass parameters to the console program steghide

问题描述

我有Steghide程序，

I have program steghide,

Steghide is a steganography program that is able to hide data in various kinds of image- and audio-files. The color- respectivly sample-frequencies are not changed thus making the embedding resistant against first-order statistical tests.

我尝试设置参数

System.Diagnostics.Process.Start("steghide.exe"，"-sf""picture.jpg");
我运行程序.它显示

http://steghide.sourceforge.net[^]

I try set parameters

System.Diagnostics.Process.Start("steghide.exe", "-sf" "picture.jpg");
I run the program. And it shows

steghide extract -sf picture.jpg
  Enter passphrase:
  wrote extracted data to "secret.txt

".

如何传递参数密码

How to pass parameter password

推荐答案

首先，阅读"steghide.exe"的文档.您需要能够将密码短语作为另一个参数传递.如果此命令行参数不可用，则解决方案仍然可行，请参见下文.

但是首先，请查看

First, read the documentation of "steghide.exe". You need to be able to pass a pass phrase as another parameter. If this command line parameter is not available, the solution is still possible, see below.

But first, look at all of the methods System.Diagnostics.Process.Start at http://msdn.microsoft.com/en-us/library/system.diagnostics.process.start.aspx[^].

There is not such signature you are trying to use, the code won''t compile. You can use Process.Start(string, string):

System.Diagnostics.Process.Start("steghide.exe", "-sf picture.jpg");

在这种用法中，所有参数都放在一个字符串中，并用空白字符分隔: http://msdn.microsoft .com/en-us/library/h6ak8zt5.aspx [ ^ ].

现在，回到密码短语没有命令行参数的情况:

更糟糕的是，那么您需要模拟用户输入.这是通过使用System.Diagnostics.Process.StandardInput完成的.您将需要重定向.为此，您将需要使用流程Start(ProcessStartInfo)方法.

确保在流程启动信息中指定重定向选项，请参见:
http://msdn.microsoft.com/en-us/library/system. diagnostics.process.startinfo.aspx [ ^ ]，
http://msdn.microsoft.com/en-us/library/system.diagnostics. processstartinfo.aspx [ ^ ].

您将在此处找到具有重定向的代码示例: http://msdn.microsoft. com/en-us/library/system.diagnostics.process.standardinput.aspx [

In this usage, all parameters go in one string, separated with the blank character: http://msdn.microsoft.com/en-us/library/h6ak8zt5.aspx[^].

Now, coming back to the situation when there is no a command line parameter for your pass phrase:

It''s worse, then you need to simulate the user input. This is done by using System.Diagnostics.Process.StandardInput. You will need to redirect it. Do do this, you will need to use the process Start(ProcessStartInfo) method.

Make sure you prescribe redirection option in your process start info, see:
http://msdn.microsoft.com/en-us/library/system.diagnostics.process.startinfo.aspx[^],
http://msdn.microsoft.com/en-us/library/system.diagnostics.processstartinfo.aspx[^].

You will find a code sample with redirection here: http://msdn.microsoft.com/en-us/library/system.diagnostics.process.standardinput.aspx[^].

You need to write your value of the pass phrase to the redirected string where required.
