All Implemented Interfaces:

public class SMIMEInputStream
extends java.io.InputStream

Clase que transforma un InputStream cualquiera en un InputStream en formato SMIME, estableciendo en la cabecera el content-type que se le pasa como argumento al constructor y codificando los bytes de entrada en base64. Modificacion introducidas por FGU para permitir generacion del SMIME a partir de un PKCS#7 que contiene una firma en paralelo: * Se intoruduce nuevo constructor a partir de un array de bytes que contiene el pkcs#7 y el contentType * Se introduce el atributo contentType para en el metodo fetchContentHeader no tener que obtenerlo de la signature * El constructor que utiliza la Signature da valor al atribute contentType
