v1.0.0 — Metal-accelerated PDF password recovery

First tagged release.

What it is: Recover passwords from encrypted PDFs on macOS — all encryption revisions (R2–R6), 15+ attack modes (dictionary, brute-force, mask, rules, hybrid, PRINCE, Markov, smart multi-phase), GPU acceleration via Metal, ARM NEON SIMD, and distributed cracking. No external dependencies.

Asset: pdfcrack-macos-arm64 — native Apple Silicon (arm64) binary, built against the macOS Metal toolchain.

Run:

shasum -a 256 -c pdfcrack-macos-arm64.sha256   # verify
xattr -d com.apple.quarantine pdfcrack-macos-arm64   # clear Gatekeeper (unsigned binary)
chmod +x pdfcrack-macos-arm64
./pdfcrack-macos-arm64 -f secret.pdf --smart -d wordlist.txt

The binary is unsigned (no Apple Developer identity), so macOS Gatekeeper requires clearing the quarantine attribute as shown. Or build from source: make pdfcrack (requires Xcode + Metal toolchain).
