PDF Decryptor

PDF Decryptor Skill

This skill removes password protection from encrypted PDF files, creating unlocked copies that can be freely accessed.

Dependencies

• Python 3.7+
• pikepdf library (see requirements.txt)

Installation

Install dependencies:

pip install -r skillset/pdf-decryptor/requirements.txt

Usage

Decrypt a single PDF

python skillset/pdf-decryptor/decrypt_pdf.py --input "path/to/encrypted.pdf" --output "path/to/decrypted.pdf" --password "your-password"

Decrypt multiple PDFs with the same password

python skillset/pdf-decryptor/decrypt_pdf.py --input "file1.pdf" "file2.pdf" "file3.pdf" --password "your-password"

When multiple input files are provided without --output, the script will automatically generate output filenames by appending _unlocked to the original filename.

Script Options

• --input or -i: Input PDF file path(s). Can specify multiple files.
• --output or -o: Output PDF file path (optional for single file, auto-generated for multiple files).
• --password or -p: Password to decrypt the PDF(s).
• --overwrite: Overwrite output files if they already exist.

Notes

• Output files are saved with the same directory as input unless a full output path is specified
• For multiple files, output names are automatically generated as {original_name}_unlocked.pdf
• The script validates that input files exist and are readable before processing
• Uses pikepdf which handles various PDF encryption types reliably
