Encrypt PDF
encrypt() is a PyPDF2 function that allows developers to add password-based encryption to a PDF file. It's useful for protecting sensitive information in a PDF document, restricting access to a PDF file, and ensuring that only authorized users can view or modify the contents of a PDF file. With encrypt(), developers can automate the process of adding encryption to a PDF file in Python.
