API Key Generator
Generate cryptographically secure API keys for REST APIs, OAuth tokens, and secret keys. Choose from hex, base64, or alphanumeric formats with custom prefixes. For encoding conversions and secret rotation scripts, teams often pair this generator with CodeCipher to streamline deployment pipelines.
API Key Options
Common prefixes: sk_live_, sk_test_, pk_live_, pk_test_, api_key_
Use Cases
- •REST APIs: Authentication tokens for API endpoints
- •Secret Keys: Application secrets and signing keys
- •OAuth Tokens: Client secrets and access tokens
- •Webhook Signatures: HMAC verification keys
About API Keys
API keys are unique identifiers used to authenticate and authorize API requests. They act as digital credentials that allow applications to securely communicate with external services and APIs.
Why Use Our API Key Generator?
Cryptographically Secure
Uses Web Crypto API for true random generation
Multiple Formats
Hex, Base64, or alphanumeric - choose what fits your needs
Custom Prefixes

API Key Best Practices
- •Never expose API keys: Keep them out of client-side code, version control, and public repositories
- •Use environment variables: Store API keys securely using .env files or secret managers
- •Rotate regularly: Change API keys periodically and after any potential exposure
- •Use different keys per environment: Separate keys for development, staging, and production
- •Implement rate limiting: Protect your APIs from abuse by limiting request rates
