Generador de cadenas aleatorias

Utilidades para desarrolladores

Genera cadenas aleatorias seguras con longitud, conjuntos de caracteres y filtro de caracteres ambiguos personalizados.

Cómo usar

Generate strings

Set the length and count, choose which character sets to include and optionally remove characters that look alike.

  1. Set the length and how many strings you need.
  2. Select uppercase, lowercase, digits or symbols.
  3. Copy the generated lines.

Randomness

The generator uses crypto.getRandomValues when available, which is suitable for tokens and one-time codes.

Preguntas frecuentes

Why exclude ambiguous characters?

Characters such as I, l, 1, O, 0 and o are easy to confuse when read aloud or typed from paper.

Is the output safe for passwords?

It uses cryptographically strong randomness, but check the length and character sets required by your security policy.
