 *
 * @params content Is only necessary to inform if the PKCS7 package is NOT
 *         ATTACHED type. If it is of type attached, this parameter will be
 *         replaced by the contents of the PKCS7 package.
 * @params signedData Value in bytes of the PKCS7 package, such as the
 *         contents of a ".p7s" file. It is not only signature as in the
 *         case of PKCS1.
