ChronosCrack is a lightweight Python tool for recovering password-protected PDF files using date-based brute-force patterns. It is designed around the common habit of some government or banking PDFs use the document holder’s date of birth as the password.
- Attempts PDF passwords based on calendar dates
- Starts from the current date and moves backward in time
- Prioritizes recent dates for faster results
- Simple and minimal terminal experience
- Brute-forces date-based password patterns
- Saves an unlocked copy of the PDF
