About this tool
Keys come from crypto.getRandomValues, the browser CSPRNG. A recognisable prefix such as sk_live_ makes leaked keys detectable by secret scanners and easy to attribute.
How long should a key be
At least 128 bits of entropy — 22 base62 characters. 32 characters is a comfortable default.
Store hashes, not keys
Persist a SHA-256 of the key plus a short display prefix. You can still verify at auth time but a database leak exposes nothing usable.

Best practices
- Treat every result as a snapshot — configuration drifts, so re-check after each deploy.
- Fix the highest-impact finding first rather than chasing a perfect score.
- Apply changes at the shared layer (proxy, CDN, base image) so every service inherits them.
- Document what you changed and when; auditors and future teammates will ask.
Secure API Key Generator — Why it matters
Infrastructure and security misconfigurations are among the most common root causes of real incidents, and almost all of them are cheap to fix once visible.
Leaving them unaddressed means failed audits, blocked enterprise deals, and avoidable exposure.
