A multithreaded PDF password cracking utility with structured search builders, checkpoint/resume, and optimized performance.
PDFRip is a multithreaded PDF password cracking utility written in Rust, designed to efficiently recover passwords from encrypted PDF documents. It supports various attack methods including dictionary attacks, bounded masks, date/number generators, and brute-forcing, with features like checkpoint/resume and JSON output for automation. The tool specifically targets the PDF Standard Security Handler's password-based encryption.
Security professionals, penetration testers, forensic analysts, and researchers who need to test or recover passwords from encrypted PDF files as part of security assessments or data recovery.
Developers choose PDFRip for its optimized performance through a prepared verifier architecture, exact progress tracking, and flexible attack modes. Its multithreaded design, checkpoint/resume capability, and structured search builders make it a reliable and efficient tool for PDF password cracking compared to generic or slower alternatives.

Uses a prepared verifier hot path to avoid rebuilding PDF parsing state per attempt, with benchmarks showing up to 15.5x lower latency for R5 AES-256 encryption compared to legacy methods.
Tracks progress based on verified password attempts, not just queued work, and supports checkpoint/resume functionality for reliable, interruptible sessions without replaying verified attempts.
Offers structured search builders for dictionary attacks, bounded masks, date/number generators, and printable-ASCII brute-forcing, with custom queries like ALICE{1000-9999} for targeted cracking.
Emits machine-readable JSON results and allows command-line tuning of threads and batch size, making it easy to integrate into automated security workflows and scripts.
Only supports the PDF Standard Security Handler (revisions R2-R6), explicitly excluding certificate-based encrypted PDFs, which restricts its use in broader encryption-cracking scenarios.
Lacks a graphical user interface, requiring terminal proficiency and making it less accessible for users who prefer visual tools or need real-time graphical feedback during operations.
Requires Rust and Cargo for source installation or downloading pre-compiled binaries, which can add setup overhead compared to tools with simpler, cross-platform installers or package managers.
