CSRF Token Generator
Generate cryptographically secure CSRF tokens as hex with configurable byte length (16–128). Code never leaves your device — generation runs locally in your browser.

Generate random tokens in hex, base64, or alphanumeric formats for secrets and sessions. Hex and base64 draw from Web Crypto (alphanumeric uses Math.random — see format notes). The API-key preset mints 64-char secrets in one click — local generation, free, no signup.
API Key Generator
Generate secure API keys with configurable length, character set, and optional prefix. Use with any authentication scheme.
String Inspector
Inspect any string — view character count, byte length, word count, line count, Unicode code points, and non-ASCII character breakdown.
MAC Address Generator
Generate random MAC addresses for labs and testing — pure random hex, no OUI or unicast-bit management. Fill virtual networks credibly — local generation, free, no signup.

Generate OTP codes — numeric, alphabetic, or hex — in batches of your chosen length. Make verification codes fast — free, local, no signup.
Frequently Asked Questions
What is a CSRF token?
A CSRF (Cross-Site Request Forgery) token is a unique, unpredictable value embedded in forms to verify that submissions originate from your site, not a malicious third party.
How are these tokens generated?
The tool uses the Web Crypto API to generate cryptographically secure random bytes, rendered as hex. The output is suitable for production use.
What encoding should I choose?
Hex only — no encoding picker. Convert the hex with your own code if a transport needs base64url.
What token length is secure?
32 bytes (256 bits) is the recommended minimum for cryptographic security. This provides 2^256 possible values, making brute-force attacks computationally infeasible.
Is the token generation done locally?
Yes. Tokens are generated using the browser's Web Crypto API. No token data is sent to any server.
