Por el momento solo funciona para claves de 104 bits pero en cualquier caso parece que cada vez estamos m\u00c3\u00a1s cerca de poder sacar claves WEP en tiempo real y en cualquier caso demuestra una vez m\u00c3\u00a1s que el protocolo WEP est\u00c3\u00a1 herido de muerte y que todos deber\u00c3\u00adamos estar usando el WPA<\/a> desde hace bastante tiempo.<\/p>\n
