Secure authentication for REST APIs and web services.
Secret Keys
Encryption keys, JWT secrets, and signing keys.
Access Tokens
Session tokens, refresh tokens, and verification codes.
Why Use Random Key Generator?
Secure applications require cryptographically random keys that are impossible to guess. Our generator uses the Web Crypto API to create truly random keys suitable for API authentication, encryption, and security tokens. Never use predictable patterns for sensitive keys.
Frequently Asked Questions
Are these keys truly random?
Yes. We use the Web Crypto API's crypto.getRandomValues() which provides cryptographically secure random numbers, suitable for security-sensitive applications.
Which format should I use?
Hex is common for encryption keys. Base64 is compact but includes special characters. Alphanumeric is URL-safe. Base58 avoids confusing characters (0/O, I/l).
How long should my keys be?
For API keys, 32-64 characters is common. For encryption (AES-256), use 32 bytes (64 hex characters). Longer keys are more secure but harder to manage.
Are these keys stored anywhere?
No. Keys are generated entirely in your browser and are never sent to any server. Refresh the page and they're gone forever.
Can I use these for production?
Yes! These keys are cryptographically secure and suitable for production use. Just make sure to store them securely and never expose them in client-side code.
