history

Project history and usage

CrackLib is a password-checking library and dictionary toolchain used to reject weak passwords before they are accepted by account-management software.

Project history

The current upstream repository describes the project as the CrackLib library and dictionaries, with source code under `src` and scripts plus content for building a full-size password dictionary under `words`.

Adoption history

CrackLib became package-manager infrastructure rather than an end-user novelty. 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.
