In the input package metadata it appears across Alpine, Homebrew, Fedora-style dnf, MacPorts, Nix, Arch pacman, and openSUSE zypper, reflecting its long role as a reusable system security component. ### How it is used The package ships command-line helpers such as `cracklib-check`, `cracklib-format`, `cracklib-packer`, `cracklib-unpacker`, `cracklib-update`, and `create-cracklib-dict`, alongside the library used by password policy integrations. ### Why package nerds care CrackLib matters to package nerds because it is shared security plumbing: distributions can package the library, dictionary builder, and utilities once, then let login stacks, account tools, and local policy scripts reuse the same weak-password checks. ### Timeline - 2019: The upstream repository recorded tag-mapping problems after a SourceForge migration. - 2024: The GitHub releases page listed the 2.10.x release line. ### Related projects - CrackLib is commonly adjacent to PAM and distribution password-policy tooling, although the upstream repository itself focuses on the library, dictionaries, and helper programs. ### Sources -
