Frequently asked questions

Are these keys cryptographically secure?
Yes. Keys are generated using window.crypto.getRandomValues() which is a CSPRNG (cryptographically secure pseudo-random number generator) built into modern browsers.
How long should an API key be?
For most use cases, 32 bytes (64 hex chars) provides 256 bits of entropy which is more than sufficient. For higher-security tokens, use 48 or 64 bytes.
