Use el XmlDsigBase64Transform objeto cuando necesite firmar los datos sin procesar asociados al contenido codificado de un elemento.

El identificador uniforme de recursos (URI) que describe el XmlDsigBase64Transform objeto se define mediante el XmlDsigBase64TransformUrl campo .

Para obtener más información sobre la Base64 transformación de descodificación, vea la sección 6.6.2 de la especificación XMLDSIG de W3C.

Constructores

XmlDsigBase64Transform()

Inicializa una nueva instancia de la clase XmlDsigBase64Transform.

Propiedades

Algorithm	Obtiene o establece el identificador uniforme de recursos (URI) que identifica el algoritmo ejecutado en la transformación actual. (Heredado de Transform)
Context	Obtiene o establece un objeto XmlElement que representa el contexto del documento en el que se está ejecutando el objeto Transform actual. (Heredado de Transform)
InputTypes	Obtiene una matriz de tipos que son entradas válidas al método LoadInput(Object) del objeto XmlDsigBase64Transform actual.
OutputTypes	Obtiene una matriz de tipos que son posibles resultados de los métodos GetOutput() del objeto XmlDsigBase64Transform actual.
PropagatedNamespaces	Obtiene o establece un objeto Hashtable que contiene los espacios de nombres que se propagan en la firma. (Heredado de Transform)
Resolver	Establece el objeto XmlResolver actual. (Heredado de Transform)

Métodos

Equals(Object)	Determina si el objeto especificado es igual que el objeto actual. (Heredado de Object)
GetDigestedOutput(HashAlgorithm)	Cuando se reemplaza en una clase derivada, devuelve el algoritmo de síntesis asociado a un objeto Transform. (Heredado de Transform)
GetHashCode()	Sirve como la función hash predeterminada. (Heredado de Object)
GetInnerXml()	Devuelve una representación XML de los parámetros del objeto XmlDsigBase64Transform que son adecuados para incluirlos como subelementos de un elemento <Transform> XMLDSIG.
GetOutput()	Devuelve la salida del objeto XmlDsigBase64Transform actual.
GetOutput(Type)	Devuelve la salida del objeto XmlDsigBase64Transform actual del tipo Stream.
GetType()	Obtiene el Type de la instancia actual. (Heredado de Object)
GetXml()	Devuelve la representación XML del objeto Transform actual. (Heredado de Transform)
LoadInnerXml(XmlNodeList)	Analiza el objeto XmlNodeList especificado como contenido específico de la transformación de un elemento <Transform>; no se admite este método porque el objeto XmlDsigBase64Transform no tiene ningún elemento XML interno.
LoadInput(Object)	Carga la entrada especificada en el objeto XmlDsigBase64Transform actual.
MemberwiseClone()	Crea una copia superficial del Object actual. (Heredado de Object)
ToString()	Devuelve una cadena que representa el objeto actual. (Heredado de Object)
