About this tool
Plan rotation dates, overlap windows and revocation steps for AI API keys based on their exposure level.
This planner turns an API key's creation date and exposure level into a concrete rotation schedule: the next due date, a dual-key overlap window, and a six-step revocation runbook. It applies the cryptoperiod concept from NIST SP 800-57 and the 90-day rotation baseline that AWS and Google Cloud publish for long-lived access keys. It is built for developers and small teams running OpenAI, Anthropic or other AI API keys without a dedicated secrets-management platform.

Presets from 30 days for client-exposed keys to a 365-day hygiene ceiling, anchored to published provider guidance.
Every scheduled rotation shows the date the old key must be revoked after the dual-key overlap window.
Six steps — issue, deploy, verify, revoke, audit, record — so revocation is never done before the new key is live.
At least every 90 days for server-side production keys — the baseline AWS and Google Cloud recommend for long-lived access keys — and closer to 30 days for keys that ever touch client-side code, notebooks or shared machines. NIST SP 800-57 frames this as limiting a key's cryptoperiod: the shorter the key lives, the smaller the window an undetected leak can be exploited.
Run both keys in parallel for a short overlap window: create the new key, deploy it to every secret store and environment, verify in the provider dashboard that traffic has moved to it, and only then revoke the old key. A 7-day overlap is a common default; the overlap must always be shorter than the rotation interval itself.
Revoke it immediately — do not wait for a scheduled rotation. Then issue a replacement with the narrowest scopes the workload needs, redeploy, and audit the old key's usage logs for unfamiliar IPs, spikes or endpoints during its lifetime, since a leaked key may have been used before you noticed. Most providers (OpenAI, Anthropic, AWS) let you disable a key instantly from the console.
No. Expiry stops future use but revocation is the explicit act of disabling the credential in the provider's console, and it should be a recorded step in every rotation. The runbook in this tool puts revocation after deployment and verification of the new key, followed by a usage audit and a log entry with the next due date.
