About This Tool

What does this tool do?

A cryptographic entropy generator powered by `crypto.randomBytes()`. Generate high-entropy API keys, passwords, session tokens, hex strings, and formatted license codes (e.g. `XXXX-XXXX-XXXX`). Customize character sets (uppercase, lowercase, numbers, symbols), prefixes (`api_live_`), suffixes, and batch counts up to 100 tokens.

When should you use it?

Use this tool to generate secure API keys for developer platforms, create strong administrative passwords, generate webhook secret keys, or produce license activation codes.
