Secure Key Generator
Generate cryptographically strong keys, tokens, and UUIDs.
Secure Key & Token Generator
Generate cryptographically secure keys for API authentication, session tokens, or encryption. Our tool uses crypto.getRandomValues() for high-entropy randomness, ensuring your keys are safe for production use.
Supported Formats
Hexadecimal (Hex)
Standard format for API keys and cryptographic secrets (256-bit+).
UUID v4
Universally Unique Identifiers for database primary keys.
WPA2
Maximum security 63-character passwords for WiFi networks.
Base64
Compact encoding for binary data, often used for web tokens.
Security Best Practices
- Never Share Private Keys: Treat generated keys like passwords.
- Use HTTPS: Always transmit keys over secure connections.
- Rotate Keys Regularly: Change your API keys and tokens periodically to minimize risk.
