PDF manager to lock or unlock your PDFs

This python program allows the user to unlock or lock several PDFs in one click. It uses a configuration file to set where the original PDFs are, where the locked/unlocked PDFs will be saved and the password. This program reads the config.txt file or uses the command line configuration. In the config.txt file is used, the first line of config.txt is the name of the source folder where the original PDFs are, the second line is the name of the destination folder where the locked/unlocked PDFs will be saved and the third line is the password. The default names are "Original PDF", "Modified PDF" and "password". Next, a folder named "Modified PDF" will be created if it doesn't already exist. Finally, the program prints out the number of PDF unlocked.
