我使用命令行来加密我发送的文件，但我试图找出如何用同样的方法对其进行解密。如果我运行命令它得到提示输入密码，但我不明白的方式来传递中使用命令行的密码。下面是我如何加密文件：

I'm using the command line to encrypt files that I am sending out but I am trying to figure out how to use the same method to decrypt them. If I run the command it get prompted for the passphrase, but I don't see a way to pass in the passphrase using the command line. Here is how I am encrypting the file:

var proc = new Process();
proc.EnableRaisingEvents = false;
proc.StartInfo.WorkingDirectory = "C:\\";
proc.StartInfo.FileName = @"C:\Progra~1\GNU\GnuPG\gpg.exe";
proc.StartInfo.Arguments = @"-e -u ""user1@example.com"" -r ""user2@example.com"" ""C:\file.csc""";
proc.Start();
proc.WaitForExit();

推荐答案

属性的 Process.StandardInput 应该给你，你可以用它来提供标准输入的密码中使用StreamWriter。

The property Process.StandardInput should give you a StreamWriter that you can use to provide the passphrase on standard input.
