Best Practices for API Secret Generation

In backend cloud infrastructure, API keys authenticate server-to-server requests without requiring interactive two-factor authentication. Consequently, API keys are prime targets for automated scanners crawling public GitHub repositories.

  • Use Base62 Alphanumeric: Stripping symbols prevents URL encoding bugs and JSON escaping issues when passing keys in Authorization: Bearer <TOKEN> headers.
  • Store Hashed in Database: Treat API keys like passwords on your backend: store only their SHA-256 or bcrypt hashes in your database so that a database breach does not expose active keys.

Frequently Asked Questions

Why should API keys include prefixes like 'sk_live_'?

Prefixes allow secret scanning tools (such as GitHub Secret Scanning and Trufflehog) to immediately identify leaked credentials in source code. They also allow internal routers to route requests to test versus production environments.
