What are Random Tokens?
Random tokens are cryptographically secure random strings used for various security purposes in web applications. They must be unpredictable and unique to prevent security vulnerabilities like session hijacking, CSRF attacks, and unauthorized access.
Common Use Cases
- API Keys: Unique identifiers for API authentication
- Session Tokens: Identify user sessions securely
- CSRF Tokens: Prevent cross-site request forgery attacks
- Password Reset Tokens: Secure password reset links
- Email Verification: Verify email addresses
- Invitation Codes: Generate unique invitation links
Token Format Comparison
| Format | Characters | Best For |
|---|---|---|
| Hexadecimal | 0-9, a-f | General purpose, database storage |
| Base64 | A-Z, a-z, 0-9, +, / | Compact representation |
| Base64URL | A-Z, a-z, 0-9, -, _ | URL-safe tokens, query parameters |
Security Best Practices
- Use at least 32 bytes (256 bits) for security-critical tokens
- Always use cryptographically secure random number generators
- Set appropriate expiration times for tokens
- Store tokens securely (hashed in database)
- Use HTTPS when transmitting tokens
- Implement rate limiting to prevent brute force attacks
