Generador de Contraseñas Seguras y Fuertes
Cree contraseñas aleatorias de alta entropía con números, símbolos y letras sin enviarlas a ningún servidor.
Cómo Usar Generador de Contraseñas Seguras y Fuertes
1. Introduzca Datos o Parámetros
Escriba su texto confidencial o seleccione algoritmos criptográficos y claves secretas.
2. Procesamiento Criptográfico Local
La API nativa W3C Web Crypto ejecuta el hash o cifrado de forma 100% privada.
3. Copie el Resultado Seguro
Copie el hash verificado o el texto cifrado directamente en su portapapeles.
Cómo Funciona Esta Utilidad
Generate truly random, cryptographically secure passwords powered by the hardware Web Crypto API. Offers customizable character sets (uppercase, lowercase, numbers, symbols), ambiguous character exclusion, multi-word memorable passphrases, numeric PINs, and real-time Shannon entropy strength metrics.
Los algoritmos operan mediante la Web Cryptography API en memoria RAM volátil. Claves y datos nunca tocan la nube.
Preguntas Frecuentes
How does this tool guarantee true randomness?
It uses window.crypto.getRandomValues(), the web standard for cryptographic pseudo-random number generation (CSPRNG), which gathers hardware entropy directly from your operating system.
Are the generated passwords saved or sent anywhere?
Never. No network requests are made. Passwords exist only in your browser memory and are discarded as soon as you close or refresh the tab.
What makes a password strong according to entropy?
Entropy measures the unpredictability of a password in bits. A score above 60 bits is considered strong against modern brute-force hardware, and above 80 bits is virtually unbreakable.
