'Implements secure API key generation with sufficient entropy, server-side

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

When not to use

• Using API keys as the sole authentication mechanism for user-facing applications
