Super quick and dirty script to call "qpdf --decrypt" on all PDF files that pdfinfo deems encrypted.

1. Ensure you have the required dependencies installed:

   • Python 3.x
   • qpdf
   • pdfinfo (usually part of the poppler-utils package)

2. Install the Python dependencies:

   pip install fire tqdm send2trash
   

3. Run the script with the path to the directory containing PDF files:

   python PDF_batch_decryptor.py /path/to/pdf/directory
   

4. The script will:

   • Check each PDF file for encryption
   • Ask if you want to decrypt each encrypted file
   • Decrypt the files you choose to decrypt
   • Move the original encrypted files to a trash directory
   • Generate a JSON file with information about the processed PDFs

Note: Make sure you have the necessary permissions to read and write files in the specified directory.
