Calcular tamaíño de Diccionario con Crunch

[D3M0N]

Encontre este script navegando por internet, y he decidido compartirlo con vosotros.

Este script funciona de la siguiente manera (x^y) * (y+1) = tamaíño en bites donde:

x = es el numero de caracteres que vamos a usar
y = es el numero de lineas que tendra nuestra wordlist

tambien podemos calcularlo sin el script usando este comando en nuestra terminal:

echo "(16^8)*(8+1)" | bc


y sin mas demora les pego el script que espero que les sea de utilidad.

Código: php
