Token Generator
Generate API tokens, NanoIDs and calculate password entropy
About Token Generator
How Token Generator Works
Generate random bytes via Web Crypto and calculate Shannon entropy and brute-force crack time estimates.
The API Token & Secret Key Generator creates cryptographically secure random API keys, bearer tokens, NanoIDs, and passwords using the Web Crypto API. It features Shannon entropy calculation to measure brute-force resistance and estimated crack time.
Frequently asked questions
Are keys generated using cryptographically secure random bytes?+
Yes. Random values are generated using CSPRNG (Cryptographically Secure Pseudo-Random Number Generators).
What is Shannon entropy in password strength?+
Entropy measures the unpredictability of the secret in bits. Over 75 bits represents strong brute-force protection.
Limitations
Always store generated production API keys in encrypted secret managers or environment variables, never in client-side code.
