Generador de tokens aleatorios

A random token is a cryptographically random string used for authentication, authorization, or as a one-time code. Tokens can be hex, base64, or base64url encoded.

Use hex for compact string representation, base64 for shorter tokens (more bits per character), and base64url for tokens that appear in URLs.

For security tokens, use at least 32 hex characters (128 bits). For API tokens, 32-64 characters provides strong security.
