Usage

Basic Usage

# Try built-in common passwords
python readpdf.py protected.pdf

# Try a specific password
python readpdf.py protected.pdf mypassword123

Wordlist Attack

# Use a wordlist (prefix with @)
python readpdf.py protected.pdf @rockyou.txt

# Max speed, unlimited rate
python readpdf.py protected.pdf @rockyou.txt --unlimited

# Custom speed (100 passwords/sec)
python readpdf.py protected.pdf @rockyou.txt -s 100

Output Options

# Save extracted text to file
python readpdf.py protected.pdf password123 -o output.txt

# JSON output with page structure
python readpdf.py protected.pdf password123 --json

# Raw text (no page separators)
python readpdf.py protected.pdf password123 --raw

# View metadata only
python readpdf.py protected.pdf --meta

PowerShell (Windows)

.\spidey.ps1 protected.pdf -Password @rockyou.txt -Unlimited -Json -o result.json

Advanced Options

OPTIONS:
  -s, --speed N          Passwords/sec (default: 10)

  --no-brute             Skip built-in passwords
  -o, --output FILE      Save text to file
  --json                 JSON output

  --meta                 Metadata only
  -q, --quiet            No progress output
  --version              Show version
  --help                 This message

How It Works

1. Password Collection — Direct password or wordlist (via @file.txt). Built-in common passwords (33 entries) are appended unless --no-brute is used.
2. Cracking Engine — For ≤100 passwords, runs sequentially. For >100, uses multiprocessing.Pool with cpu_count - 1 workers for parallel cracking via imap_unordered.
3. Decryption — Uses pypdf.PdfReader.decrypt() to test each password.
4. Extraction — Once unlocked, text is extracted from every page using pypdf.extract_text().
5. Output — Printed to stdout or saved to file in your chosen format (text/raw/JSON).
