# Random String Generator

> Generate random alphanumeric strings with a charset and length you choose. Handy for tokens, test IDs, and dummy keys. Uses local randomness so generated values are not logged by a hosted generator.

Runs in your browser. Nothing is uploaded.

## About this tool

Build a random string from letters, digits, dash/underscore, and extra characters you type. Length is capped; values come from crypto.getRandomValues, not Math.random. Hit Generate when you want a new token without changing length. If every charset toggle is off and the extra box is empty, output is empty rather than a fake default.

How to use: set length, toggle charsets, add any extra symbols, copy. Good for test IDs, nonces, and dummy API keys. Do not treat this as a password generator if you need entropy estimates and ambiguous-character filters; use the password tool instead.

Example: length 24 with letters and numbers is a typical test token. Extra '!@' adds those two symbols to the pool. Generated values are not stored and are not shown to anyone else.

RNG is Web Crypto in this browser. Tokens never go to a hosted generator that might log them. Related: UUID generator for RFC identifiers, random number for numeric samples.

## FAQ

### Is this a password generator?

It can make random tokens, but the dedicated password tool adds charset guidance and an entropy hint. Use that for secrets you will type often.
