Implementing API Key Security Controls When to Use - Designing secure API key generation with sufficient entropy and identifiable prefixes for leak detection - Implementing server-side API key hashing (never storing keys in plaintext) with SHA-256 or bcrypt - Building key rotation workflows that allow zero-downtime key replacement for API consumers - Configuring per-key scoping to limit each API key to specific endpoints, IP ranges, and rate limits - Setting up automated monitoring for API key leakage in GitHub repos, logs, and client-side code Do not use API keys as the sole authentication m…
