C#调用GPG命令进行加密解密文件操作

public void GPG()
{
string password = "1234567890";

System.Diagnostics.ProcessStartInfo psi = new System.Diagnostics.ProcessStartInfo("cmd.exe");
psi.CreateNoWindow = true;
psi.UseShellExecute = false;
psi.RedirectStandardInput = true;
psi.RedirectStandardOutput = true;
psi.RedirectStandardError = true;

psi.WorkingDirectory = @"D:\sofe\GnuPG";
System.Diagnostics.Process process = System.Diagnostics.Process.Start(psi);

//解密
string sCommandLine = @"gpg --passphrase 1234567890 --output C:\Users\LWP\Desktop\cc.txt --decrypt C:\Users\LWP\Desktop\cc.txt.gpg";

//加密
//string sCommandLine = @"gpg -r liwenping -e C:\Users\LWP\Desktop\cc.txt";

process.StandardInput.WriteLine(sCommandLine);

process.StandardInput.Flush();
process.StandardInput.Close();

process.WaitForExit();

string result = process.StandardOutput.ReadToEnd();
string error = process.StandardError.ReadToEnd();
process.Close();
process.Dispose();
}

//使用前先安装好GPG
