If you use Pycharm, you can:

* Open the "Run" menu.
* Select the option "Debug...".
* Then a context menu shows up.
* Select the file to debug (in this case, `main.py`).

		outputFileName = strings.Replace(inputFileName, ".enc.", ".", 1) + ".zip"
	default:
		outputFileName = inputFileName + ".decrypted"
	}

	// Open the input and create the output file
	input, err := os.Open(inputFileName)
	fatalErr(err)
	defer input.Close()

	// Decrypt the inspect data
	switch {
	case *keyHex != "":
		// Backup any already existing output file
