Generating Secure API Tokens and Secrets
Key Takeaways
- API tokens and secrets must be generated using cryptographically secure random number generators, not predictable algorithms.
- Token length and character set directly impact security — a 32-character hex token provides 128 bits of entropy.
- All tokens are generated in your browser using cryptographic randomness — they are never stored or transmitted.
API tokens and secrets are the keys to your application's kingdom. They authenticate services, authorize access to resources, and protect sensitive endpoints. Generating tokens with sufficient randomness and entropy is critical — predictable tokens can be guessed or brute-forced, leading to unauthorized access and data breaches.
API key leaks exposed in public repositories lead to an average of $1.2 million in damages per incident.
Cost of Compromise
Common Use Cases
API Key Generation
Generate high-entropy API keys for service-to-service authentication, ensuring each key is cryptographically random and unique.
Webhook Signing Secrets
Create strong shared secrets for HMAC-based webhook signature verification between your application and third-party services.
Session Token Creation
Generate unpredictable session identifiers that resist brute-force guessing and session hijacking attacks.
Environment Variable Secrets
Produce strong random values for JWT signing keys, encryption keys, and other secrets stored in environment configuration.
Pro Tips
Use at least 128 bits of entropy (32 hex characters or 22 Base64 characters) for any security-sensitive token.
Prefix tokens with a service identifier (e.g., 'sk_live_') to make it easier to identify token types and rotate them.
Store tokens securely — use environment variables or secret management services, never hardcode them in source files.
Implement token expiration and rotation policies to limit the window of exposure if a token is compromised.
All tokens and secrets are generated entirely in your browser using the Web Crypto API's secure random number generator. Generated values are never stored, logged, or transmitted to any server.
