In my work I use the Command Line, and wanted to improve the work in my company. To do this, I thought about creating a C # program for people who do not know how to work with the command line.

I thought of putting a button to open a CNF file, and with another button (built-in command), and saved in CSR file on Desktop.

That is, the button would open the command line and put the following formula:

cd desktop
openssl -req -new -config cert.cnf -out "cert.csr" out.

That is, the file myfile.csr will be on the desktop, and through the command line, will change to myfile.cnf .

Suggestions?

c# cmd openssl

Do you want to do the same as cmd procedure inside an application written in C #? If this is it, then you can use System.Diagnostics.Process .

You will have to join the command cd with openssl using & , see an example:

System.Diagnostics.Process process = new System.Diagnostics.Process();
System.Diagnostics.ProcessStartInfo startInfo = new System.Diagnostics.ProcessStartInfo();

//Oculta cmd
startInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;

//Chama CMD
startInfo.FileName = "cmd.exe";

//seu comando
startInfo.Arguments = "/C cd Desktop& openssl \"myfile.csr\" -req -new -config myfile.cnf out.";

process.StartInfo = startInfo;
process.Start();

For simplicity you can pass the arguments to Start() , as is the response from SOen :

const string strCmdText = "/C cd Desktop& openssl \"myfile.csr\" -req -new -config myfile.cnf out.";
...
process.Start("CMD.exe", strCmdText);

Here is a variation of posted by Guilherme Nascimento :

public void ExecutarComandoSSL(string arquivoCNF, string arquivoCSR) {
    using (System.Diagnostics.Process processo = new System.Diagnostics.Process()) {
        processo.StartInfo.FileName = Environment.GetEnvironmentVariable("comspec");
        processo.StartInfo.WorkingDirectory = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);
        processo.StartInfo.Arguments = string.Format("/c openssl req -new -config {0} -out \"{1}\"", arquivoCNF, arquivoCSR);

        //processo.StartInfo.CreateNoWindow = true;
        processo.Start();
        processo.WaitForExit();
    }
}

Note : The command will execute in the current user's desktop directory. Information .

Do the following, in the form, put:

Two buttons, one to fetch the CNF , and another to save in CSR format.
Place a OpenFileDialog component.

Create a class to retrieve and save information about the files:

public static class VariaveisGlobais 
{
    public static string CNF { get; set; }
    public static string CSR { get; set; }
}

In the button responsible for searching the CNF file, place:

DialogResult resposta = openFileDialog1.ShowDialog();
if (resposta == DialogResult.OK) {
     string arquivo = openFileDialog1.FileName;

     VariaveisGlobais.CNF = arquivo;
     VariaveisGlobais.CSR = "cert.csr"; // Leia a sugestão
}

Hint : You can use the SaveFileDialog component to allow the user to save the file to location of your choice.

In the CSR button, save the file:

string arquivoCNF = VariaveisGlobais.CNF;
string arquivoCSR = VariaveisGlobais.CSR;

// Aqui você poderia tratar o conteúdo das variáveis
ExecutarComandoSSL(arquivoCNF, arquivoCSR);
