🔐 Generated API Key

⚠️ Security Best Practices

Never commit to version control: Keep API keys out of Git repositories and public code. Use environment variables: Store keys in .env files or secure configuration systems. Implement key rotation: Regularly generate new keys and deprecate old ones. Restrict permissions: Limit API key access to only necessary resources and operations. Monitor usage: Track API key usage for suspicious activity. Use HTTPS only: Always transmit API keys over encrypted connections.

📋 Format Guidelines

Alphanumeric: Most versatile, works in all systems (32-64 chars recommended). Hexadecimal: Compact, efficient for binary data (32-64 chars). Base64: Good for data transmission, URL-safe variants available (32-88 chars). UUID v4: Standardized format, excellent for unique identifiers (36 chars fixed).
