bchunk (binchunker) splits a .bin/.cue CD image into .iso for the data track and .wav files for each audio track. The canonical tool for turning a mixed-mode BIN/CUE into something you can mount or burn.
fcrackzip is a small, old, command-line tool that recovers passwords on classic-ZipCrypto-encrypted .zip files. Brute-force or dictionary, runs everywhere, still useful in 2026 — with hashcat/john as the modern follow-up when it isn't fast enough.
pdfcrack is a small, single-threaded CPU tool for recovering lost PDF user and owner passwords. Fine for 40-bit RC4 and small dictionary attacks; for 128/256-bit AES PDFs, migrate to pdf2john + hashcat on a GPU.
