Secret Key Generator
Generate cryptographically secure random keys for API tokens, encryption, JWT secrets, and more. All keys are generated locally in your browser.
Generate Secret Key
Hexadecimal key - Perfect for encryption keys, session tokens, and database IDs
Adding a salt will hash the generated key with SHA-256
Common Use Cases
API Authentication
Generate secure API keys for authenticating requests to your services
Encryption Keys
Create strong encryption keys for AES, RSA, or other cryptographic algorithms
Session Tokens
Generate unique session identifiers for user authentication systems
JWT Secrets
Create high-entropy secrets for signing JSON Web Tokens
Security Best Practices
- •Never commit secrets: Keep API keys and secrets out of version control
- •Use environment variables: Store secrets in environment variables, not in code
- •Rotate regularly: Change API keys and secrets periodically
- •Minimum length: Use at least 256-bit (32 byte) keys for production systems
- •Secure storage: Use a secret management service like AWS Secrets Manager or HashiCorp Vault
- •Limit scope: Grant API keys only the minimum required permissions
