• Python 3.x
• pypdf library

Installation

1. Clone this repository:

git clone https://github.com/queenie-lee/Encrypt-PDF.git
cd Encrypt-PDF

2. Install dependencies:

pip install -r requirements.txt

Usage

Command Line Arguments

Encrypt PDFs:

python main.py encrypt -s /path/to/source -d /path/to/destination -p yourpassword

Decrypt PDFs:

python main.py decrypt -s /path/to/source -d /path/to/destination -p yourpassword

With completed directory (optional):

python main.py encrypt -s /path/to/source -d /path/to/destination -p yourpassword -c /path/to/completed

Using a Config File

Create a config.json file with your settings:

{
  "source": "files/input",
  "destination": "files/output",
  "completed": "files/completed",
  "password": "yourpassword"
}

Then run:

python main.py encrypt -f config.json

or

python main.py decrypt -f config.json

Arguments

• mode (required): encrypt or decrypt
• -f, --file: Path to JSON config file
• -s, --source: Source directory containing PDF files
• -d, --destination: Destination directory for processed files
• -p, --password: Password for encryption/decryption
• -c, --completed: Directory to move source files after processing (optional)

Note: Command-line arguments override config file settings.

Examples

Example 1: Encrypt all PDFs in a folder

python main.py encrypt -s ./documents -d ./encrypted -p MySecurePass123

Example 2: Decrypt PDFs and archive originals

python main.py decrypt -s ./encrypted -d ./decrypted -p MySecurePass123 -c ./archive

Example 3: Use config file for encryption

python main.py encrypt -f config.json
