## プロジェクトの歴史と使われ方
John the Ripper is a classic open-source password security auditing and recovery tool. Its core identity is a fast Unix password cracker, but the Openwall documentation also presents it as a cross-platform tool for many Unix-like systems, macOS, Windows, DOS, BeOS, and OpenVMS.
### プロジェクトの歴史
According to Solar Designer on the Openwall john-users list, John the Ripper 1.0 was released in 1996 as a DOS replacement for Cracker Jack, built with DJGPP and optimized for 486 and Pentium systems. The same account says the incremental-mode prototypes date to 1995, the project became open source in 1997, and the 1.5 rewrite in 1998 formed the basis of later releases.
Openwall's project page separates core John from Jumbo: the core release is the smaller, more conservative line, while Jumbo carries broader community functionality. The openwall/john GitHub repository was created in 2011 and serves the development source referenced from the official homepage.
### 採用の歴史
John became part of Unix security practice because it automated weak-password detection against common crypt(3) hashes and later gained support for Kerberos/AFS, Windows LM, DES tripcodes, and many additional formats. Openwall notes that John is included in Owl, Debian, Fedora, Gentoo, Mandriva, SUSE, and BSD ports or packages.
Homebrew keeps a separate john formula for the core package, conflicting with john-jumbo so users choose between the conservative package and the enhanced branch.
### 使われ方
The core workflow is to feed John password hashes, let it identify or be told a format, crack with wordlist, single, or incremental modes, and save cracked values to john.pot. Related tools such as unshadow and unique support the Unix password-auditing workflow around the main john executable.
### パッケージ好きにとっての重要性
John is one of the packages that makes Unix security tooling feel like a package-manager canon item: tiny command name, long history, distro ubiquity, and a split between core stability and Jumbo reach. For maintainers, it is also a reminder that packaging security tools means preserving documentation, wordlists, CPU optimizations, and legal/licensing details alongside the executable.
