Yes. After the initial page load, CSRF Token Generator runs entirely on your device with no internet connection needed. All processing is done locally.
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.
The tool uses the Web Crypto API to generate cryptographically secure random bytes, then encodes them in your chosen format (hex, base64, or base64url). The output is suitable for production use.
Base64url is recommended for URL-safe tokens in form fields. Hex is human-readable and easy to debug. Base64 is compact but may need URL-encoding in some contexts.
32 bytes (256 bits) is the recommended minimum for cryptographic security. This provides 2^256 possible values, making brute-force attacks computationally infeasible.
Yes. Tokens are generated using the browser's Web Crypto API. No token data is sent to any server.
