A 32-byte token contains 256 random bits before encoding; HEX produces 64 characters.Generate cryptographically random API keys and tokens in batches.
Prepare your input
Choose 16–64 random bytes, output encoding and a label prefix.
Generate up to 100 independent keys using Web Crypto.
Review and export
Copy the keys or download a text file.

Scope and privacy
These are random tokens, not issued API credentials or public/private key pairs. A prefix does not add entropy.
