CSRF Token Generator

About CSRF Tokens

Cross-Site Request Forgery (CSRF) tokens protect your web applications by ensuring that requests come from legitimate users and not from malicious sites.

Token Types

Random Token

Generates a completely random string using cryptographically secure random values. These tokens are unpredictable and suitable for most CSRF protection needs.

Timestamp-Based

Combines a timestamp with random data to create a token that can be validated for freshness. Useful when you need to enforce token age limitations.

HMAC-Based

Uses a Hash-based Message Authentication Code approach to generate tokens that can be cryptographically verified. Best for high-security applications.

Expiry Times

15m

15 minutes - For sensitive operations that should be completed quickly

1h

1 hour - Standard for most web applications

24h

24 hours - For longer user sessions

7d

7 days - For extended access needs

FAQ

What is CSRF (Cross-Site Request Forgery)?

CSRF is an attack that forces authenticated users to submit unwanted requests to a web application where they're currently logged in. CSRF tokens help prevent these attacks by requiring a unique, unpredictable value with each request.

How do CSRF tokens work?

CSRF tokens are unique, random values generated for each session or form submission. When a form is submitted, the server validates that the token matches the one associated with the user's session, ensuring the request came from a legitimate source.

What makes a good CSRF token?

A good CSRF token should be: random and unpredictable, unique per session/request, sufficiently long (at least 32 bytes), cryptographically secure, and time-limited. It should also be validated server-side before processing any request.

Where should I include CSRF tokens?

CSRF tokens should be included in all state-changing requests (POST, PUT, DELETE) through either a hidden form field, custom HTTP header, or as part of the request body. They should never be included in URLs as they might be leaked through Referer headers.

How long should CSRF tokens be valid?

Token validity period depends on your security requirements. Common practices include: per-request tokens (most secure), per-session tokens, or time-limited tokens (e.g., 1-24 hours). Shorter validity periods provide better security but may impact user experience.
