## Projektgeschichte und Nutzung

checkpwn is a Rust CLI for querying Have I Been Pwned account, paste, and password-breach data. It is small, but source-backed enough to document as a package-manager convenience wrapper around a security API.

### Projektgeschichte

The brycx/checkpwn repository was created in May 2018. The README describes checkpwn as a tool to check Have I Been Pwned and determine whether passwords need changing.

The Cargo metadata identifies it as a command-line utility with password, security, and HIBP keywords. The project continued to receive releases through 0.6.0 in March 2026, when it moved to Rust Edition 2024 and updated dependencies.

### Adoptionsgeschichte

The README documents installation through Cargo and Homebrew, while the batch metadata also lists Nix. This is typical adoption for a focused Rust CLI: cargo install first, then package-manager formulas for repeatable workstation setup.

Adoption appears niche rather than ecosystem-defining, with modest GitHub star counts, but the tool solves a clear packageable task: local HIBP checks without writing API glue.

### Wie es verwendet wird

Users register a Have I Been Pwned API key with checkpwn register, which writes checkpwn.yml in the user's configuration directory, then use checkpwn acc for accounts or lists and checkpwn pass for passwords.

For account checks, the README says checkpwn queries both the HIBP paste and account databases. Password checking is separated from account checking, matching the common operational distinction between exposed accounts and compromised password material.

### Warum Paket-Nerds sich dafür interessieren

checkpwn is package-nerd interesting as a compact Rust security CLI with Cargo, Homebrew, and Nix distribution. It shows the pattern of wrapping a popular web security service in a local command that stores minimal configuration and can be scripted.

Its config-path behavior also matters to packagers because API keys are user state, not package state.
