Frequently Asked Questions
What's the difference between key formats?
Hex uses 0-9 and A-F (great for encryption), Base64 is compact and URL-safe, alphanumeric is human-readable, UUID follows standard format, and custom lets you define characters.
How secure are these generated keys?
All keys use cryptographically secure random generation (crypto.getRandomValues()) and are generated locally in your browser - never sent to servers.
What length should I use for different purposes?
API keys: 32-64 chars, Encryption keys: follow algorithm requirements (256-bit = 32 bytes), JWT secrets: 64+ chars, Database tokens: 32+ chars.
Can I use these keys in production?
Yes! These keys are suitable for production use. However, always follow your organization's security policies and consider key rotation schedules.
What's the difference between API keys and encryption keys?
API keys authenticate and authorize access to services, while encryption keys protect data. API keys are often longer and alphanumeric, encryption keys follow specific algorithm requirements.
Should I store generated keys?
Never store sensitive keys in plain text. Use environment variables, key management services, or encrypted configuration files. Avoid committing keys to version control systems.
