Hi I'm trying to encrypt the zip using the GPG im able to do that from a command line. When i integrated that in a C# application it worked well. But when i integrated it with a Windows service i got Error as gpg2.exe closed

Following are the exception details

Following is the code i'm using to encrypt

public bool Encrypt(string inRecipient, string sourceFile, string destinationFile) {

/// File info
FileInfo fi = new FileInfo(sourceFile);

ProcessStartInfo s = new ProcessStartInfo("cmd.exe");
s.CreateNoWindow = true;
s.UseShellExecute = false;
s.RedirectStandardInput = true;
s.RedirectStandardOutput = true;
s.RedirectStandardError = true;
s.WorkingDirectory = new FileInfo(pgpPath).DirectoryName;

bool processExited = false;

using (Process p = Process.Start(s))
{

    string recipient = " --recipient \"" + inRecipient + "\"";
    string output = " --output \"" + destinationFile + "\"";
    string encrypt = " --encrypt \"" + sourceFile + "\"";
    string homedir = " --homedir \"" + HomeDirectory + "\"";
    string cmd = "\"" + PgpPath + "\" " + recipient + output + encrypt;

    p.StandardInput.WriteLine(cmd);
    p.StandardInput.Flush();
    p.StandardInput.Close();
    processExited = p.WaitForExit(3500);
    p.Close();
}
return processExited;

}

Im not able to find anything using the Problem signature. Please help

Thanks in advance!!

Answer 1

This is most likely caused by a user context problem. Probably the user account the services is running under doesn't have access to the file you are trying to encrypt.

To test this theory, go to the service properties and in the 'Log On' tab enter an account that you know has access to the file. Preferably the same account/password that you are using to run the C# application

You should also be sure that your code is using a full path to the file to encrypt and not a relative path.
