Is it safe to check my password using this tool?

Yes. This agent uses the K-Anonymity model. Only the first 5 characters of your password's SHA-1 hash are sent to the HIBP server. The full password or full hash never leaves your local environment, making it cryptographically safe.

Where can I get an API Key?

You can purchase an API key directly from the [HIBP website](https://haveibeenpwned.com/API/Key). It requires a small monthly subscription to prevent mass scraping and abuse.
