The official site describes it as small, dependency-free, and intended for GNU/Linux and other POSIX-compatible systems. ### プロジェクトの歴史 PDFCrack was written by Henning Noren after he lost access to a PDF he owned and wanted to learn more about PDF document security. The official FAQ says the project continued because there was no open-source or free PDF password recovery program that met that need. The SourceForge project page records the project as registered on 2006-05-26, with GPLv2 licensing, C as the programming language, and a console/terminal user interface. ### 採用の歴史 PDFCrack became a common package-manager security utility because it is narrow, portable, and easy to build. Its presence across Unix-like package ecosystems reflects the demand for a simple CLI that can run wordlist and brute-force recovery jobs without a larger cracking framework. ### 使われ方 The official feature list covers standard security handler revisions 2, 3, and 4, owner and user password recovery, wordlist and brute-force modes, simple permutations, benchmarking, and save/load of running jobs. The FAQ frames supported use as recovering passwords or content the user owns but has lost access to. It explicitly says PDFCrack is not for changing or overriding copy, print, or permission restrictions. ### パッケージ好きにとっての重要性 For package nerds, PDFCrack is the archetypal tiny security CLI: a single-purpose C tool, no external dependencies, packageable across POSIX systems, and useful in forensics or recovery contexts where a full GPU cracking suite is unnecessary. ### タイムライン - 2006: SourceForge records the project registration date as 2006-05-26. - 2008: The official website and FAQ show a last modified date of 2008-07-08. - 2025: SourceForge records a project last update date of 2025-09-14. ### Related projects - PDFCrack is related by domain to broader password-recovery tools and PDF utilities, but the official project materials present it as a standalone command-line tool for PDF password recovery. ### ソース - - - ## セキュリティノート escape, surveillance, or offensive capability signal. - **Geiger リスク:** red / 中 - escape, surveillance, or offensive capability signal ## ソースデータベース詳細 - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** pdfcrack - **Version Scheme:** 0 - **Revision:** 0 - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** stable ## 他のパッケージマネージャ記録 - Debian apt - pdfcrack - 0.20-1: normalized package name match | Debian stable package indexes: pdfcrack from https://deb.debian.org/debian/dists/stable/main/binary-amd64/Packages.xz | PDF files password cracker | http://pdfcrack.sf.net - Nix - pdfcrack: normalized package name match | nixpkgs package indexes: pkgs/by-name/pd/pdfcrack/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 - Ubuntu apt - pdfcrack - 0.20-1: normalized package name match | Ubuntu 24.04 LTS package indexes: pdfcrack from https://archive.ubuntu.com/ubuntu/dists/noble/universe/binary-amd64/Packages.gz | PDF files password cracker | http://pdfcrack.sf.net - apk - pdfcrack - 0.21-r0: normalized package name match | Alpine Linux edge package indexes: pdfcrack from https://dl-cdn.alpinelinux.org/alpine/edge/testing/x86_64/APKINDEX.tar.gz | Command line, password recovery tool for PDF-files. | https://pdfcrack.sourceforge.net/ - dnf - pdfcrack - 0.21-2.fc44: normalized package name match | Fedora Rawhide package metadata: pdfcrack from https://dl.fedoraproject.org/pub/fedora/linux/development/rawhide/Everything/x86_64/os/repodata/e5ca8ce900cd68f5419e1c39ae517343100b306336cbaeb70a3c153121d95094-primary.xml.zst | A Password Recovery Tool for PDF files | http://pdfcrack.sourceforge.net/ - pacman - pdfcrack - 0.21-1: normalized package name match | Arch Linux sync databases: pdfcrack from https://geo.mirror.pkgbuild.com/extra/os/x86_64/extra.db.tar.gz | Password recovery tool for PDF-files | https://pdfcrack.sourceforge.net/ ## 関連リンク - [Secret-risk packages](https://www.automicvault.com/ja/pkg/secret-risk-packages/) - Has protected-tool coverage, approval-gate, or non-low Geiger security signals. - [Terminal utility packages](https://www.automicvault.com/ja/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Networking and protocol packages](https://www.automicvault.com/ja/pkg/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [Media and graphics packages](https://www.automicvault.com/ja/pkg/media-graphics-tools/) - Matched media, image, audio, video, or graphics metadata. - [hashcat](https://www.automicvault.com/ja/pkg/brew/hashcat/) - Shares av.db curated category or tags: cli, password-recovery, security. - [pdfalyzer](https://www.automicvault.com/ja/pkg/brew/pdfalyzer/) - Shares av.db curated category or tags: cli, pdf, security. - [pdfrip](https://www.automicvault.com/ja/pkg/brew/pdfrip/) - Shares av.db curated category or tags: cli, password-recovery, pdf, security. - [fcrackzip](https://www.automicvault.com/ja/pkg/brew/fcrackzip/) - Shares av.db curated category or tags: cli, password-recovery, security. - [truecrack](https://www.automicvault.com/ja/pkg/brew/truecrack/) - Shares av.db curated category or tags: cli, password-recovery, security. - [wirouter_keyrec](https://www.automicvault.com/ja/pkg/brew/wirouter-keyrec/) - Shares av.db curated category or tags: cli, password-recovery, security. - [botan](https://www.automicvault.com/ja/pkg/brew/botan/) - Shares av.db curated category or tags: cli, cryptography, security. - [gnutls](https://www.automicvault.com/ja/pkg/brew/gnutls/) - Shares av.db curated category or tags: cli, cryptography, security. ## Combined YAML source View the package source record on GitHub.
