Agregar un campo de firma invisible adding-an-invisible-signature-field
Las firmas digitales aparecen en los campos de firma, que son campos de formulario que contienen una representación gráfica de la firma. Los campos de firma pueden ser visibles o invisibles. Los firmantes pueden utilizar un campo de firma preexistente o se puede agregar un campo de firma mediante programación. En cualquier caso, el campo de firma debe existir antes de que se pueda firmar un documento PDF. Puede agregar mediante programación un campo de firma mediante la API de Java del servicio de firma o la API del servicio web de firma. Puede agregar más de un campo de firma a un documento PDF. Sin embargo, cada nombre de campo de firma debe ser único.

Modificar campos de firma modifying-signature-fields-nbsp
Puede modificar los campos de firma que se encuentran en un documento PDF. La modificación de un campo de firma implica la manipulación de sus valores del diccionario de bloqueo de campos de firma o valores del diccionario de valores de semillas.
Un diccionario de bloqueo de campos especifica una lista de campos que se bloquearán cuando se firme en el campo de firma. Un campo bloqueado impedirá que los usuarios lo editen. Un diccionario de valores semillas contiene información de la restricción que se utilizará en el momento en que se aplique la firma. Por ejemplo, puede cambiar los permisos que controlan las acciones que se pueden producir sin invalidar una firma.
Si modifica un campo de firma existente, podrá editar el documento PDF para reflejar los cambios en los requisitos empresariales. Por ejemplo, un requisito empresarial nuevo requiere bloquear todos los campos del documento después de firmarlo.

/**
* You can modify signature fields that are located in a PDF document by using the Java API and web service API. Modifying a signature field involves
* manipulating its signature field lock dictionary values or seed value dictionary values.
* A field lock dictionary specifies a list of fields that are locked when the signature field is signed. A locked field prevents users from making
* changes to the field. A seed value dictionary contains constraining information that is used at the time the signature is applied.
* For example, you can change permissions that control the actions that can occur without invalidating a signature.
* By modifying an existing signature field, you can make changes to the PDF document to reflect changing business requirements. For example,
* a new business requirement may require locking all document fields after the document is signed.
* This section explains how to modify a signature field by amending both field lock dictionary and seed value dictionary values.
* Changes made to the signature field lock dictionary result in all fields in the PDF document being locked when a signature field is signed.
* Changes made to the seed value dictionary prohibit specific types of changes to the document.
*

Certificar documentos PDF certifying-pdf-documents-nbsp
Puede proteger un documento PDF certificándolo con un tipo de firma concreto denominada firma certificada. Una firma certificada se distingue de una firma digital de las siguientes maneras:
- Debe ser la primera firma aplicada al documento PDF. Es decir, cuando se aplica la firma certificada, los demás campos de firma del documento deben estar sin firmar. Solo se permite una firma certificada en un documento PDF. Para firmar y certificar un documento PDF, debe certificarlo antes de firmarlo. Después de certificar un documento PDF, puede firmar digitalmente en los campos de firma adicionales.
- El autor o el creador del documento pueden especificar que el documento se puede modificar de determinadas formas sin invalidar la firma certificada. Por ejemplo, el documento puede permitir rellenar formularios o realizar comentarios. Si el autor especifica que no se permite una modificación determinada, Acrobat impedirá que los usuarios modifiquen el documento de esa manera. Si se realizan estas modificaciones, la firma certificada no será válida. Además, Acrobat emitirá una advertencia cuando cualquier usuario abra el documento. (Con las firmas no certificadas no se evitan las modificaciones y las operaciones de edición normales no invalidan la firma original).
- En el momento de la firma, el documento se analizará para detectar tipos de contenido específicos que puedan hacer que el contenido de un documento sea ambiguo o engañoso. Por ejemplo, una anotación podría complicar algún texto de una página que sea importante para comprender qué se certifica. Se puede proporcionar una explicación (autenticación legal) sobre dicho contenido.

/**
* You can secure a PDF document by certifying it with a particular type of signature called a certified signature.
* A certified signature is distinguished from a digital signature in these ways:
*
* It must be the first signature applied to the PDF document; that is, at the time the certified signature is applied, any other signature fields in the document must be unsigned.
* Only one certified signature is permitted in a PDF document. If you want to sign and certify a PDF document, you must certify it before signing it.
* After you certify a PDF document, you can digitally sign additional signature fields.
*
* The author or originator of the document can specify that the document can be modified in certain ways without invalidating the certified signature. For example,
* the document may permit filling in forms or commenting. If the author specifies that a certain modification is not permitted, Acrobat restricts users from modifying the document
* in that way. If such modifications are made, such as by using another application, the certified signature is invalid and Acrobat issues a warning when a user opens the document.
* (With non-certified signatures, modifications are not prevented, and normal editing operations do not invalidate the original signature.)
*
* At the time of signing, the document is scanned for specific types of content that could make the contents of a document ambiguous or misleading. For example, an annotation could
* obscure some text on a page that is important for understanding what is being certified. An explanation (legal attestation) can be provided about such content.
* You can programmatically certify PDF documents by using the Signature service Java API or the Signature web service API. When certifying a PDF document, you must reference a security
* credential that exists in the Credential service.
*
* Note: When certifying and signing the same PDF document, if the certify signature is not trusted, a yellow triangle appears next to the first sign signature when you open the PDF document in Acrobat or Adobe Reader.
* The certifying signature must be trusted to avoid this situation.
*
* The following Java code example certifies a PDF document that is based on a PDF file.
*
* PreRequisites - Digital certificate for certifying the document has to be uploaded on AEM Key Store.

Proteger documentos securing-documents
secureDocument le permite cifrar, firmar/certificar y leer un documento PDF, ya sea de forma individual o en cualquier combinación en un orden determinado. Para acceder a cualquiera de estas funcionalidades, apruebe el argumento correspondiente. Si es nulo, se supondría que el procesamiento en particular no es necesario.
Cifrar documentos PDF con contraseña
Cuando se cifra un documento PDF con una contraseña, cualquier usuario deberá especificar la contraseña para abrir el documento PDF en Adobe Reader o Acrobat. Además, antes de que otra operación de los servicios de documentos de AEM Forms utilice el documento, se deberá desbloquear un documento PDF cifrado con contraseña.
Cifrar documentos PDF con certificados
El cifrado basado en certificados permite cifrar un documento para destinatarios específicos mediante tecnología de clave pública.
Se pueden otorgar permisos a varios destinatarios diferentes para el documento. Muchos aspectos del cifrado son posibles gracias a la tecnología de claves públicas.
Se utiliza un algoritmo para generar dos números grandes, conocidos como claves, que tienen las siguientes propiedades:
- Se utiliza una clave para cifrar un conjunto de datos. Posteriormente, solo se puede utilizar la otra clave para descifrar los datos.
- Es imposible distinguir una clave de la otra.
- Una de las claves actúa como clave privada de un usuario. Es importante que solo el usuario tenga acceso a esta clave.
- La otra clave es la clave pública del usuario, que se puede compartir con otros.
Un certificado de clave pública contiene la clave pública y la información de identificación del usuario. Se utiliza el formato X.509 para almacenar certificados. Los certificados los suele emitir y firmar digitalmente una autoridad de certificación (CA), que es una entidad reconocida que proporciona confianza en la validez del certificado. Los certificados tienen una fecha de caducidad tras la cual ya no son válidos.
Además, las listas de revocación de certificados (CRL) proporcionan información sobre los certificados revocados antes de su fecha de caducidad. Las listas CRL las publican periódicamente las autoridades certificadoras. El estado de revocación de un certificado también se puede recuperar mediante el Protocolo de estado de certificado en línea (OCSP) a través de la red.
Aplicar derechos de uso a documentos PDF
Puede aplicar derechos de uso a documentos PDF mediante la API de cliente Java y el servicio web de ampliación de Reader. Los derechos de uso pertenecen a una funcionalidad que está disponible de forma predeterminada en Acrobat pero no en Adobe Reader, como la capacidad de agregar comentarios a un formulario o rellenar los campos del formulario y guardarlo. Los documentos PDF a los que se les han aplicado derechos de uso se denominan “documentos con derechos activados”. Un usuario que abre un documento con derechos activados en Adobe Reader puede realizar las operaciones que están habilitadas para ese documento específico.
Antes de poder ampliar un documento PDF con un certificado, Reader debe asegurarse de agregar el certificado al repositorio de claves de AEM.
Firma digital de documentos PDF
Las firmas digitales se pueden aplicar a documentos PDF para proporcionar cierto nivel de seguridad. Las firmas digitales, como las firmas manuscritas, proporcionan un medio para que los firmantes se identifiquen y hagan declaraciones sobre un documento.
La tecnología utilizada para firmar documentos digitalmente ayuda a garantizar que tanto el firmante como los destinatarios tengan una idea clara de lo que se firmó y estén seguros de que el documento no se ha alterado desde que se firmó.
Los documentos PDF se firman mediante tecnología de clave pública. Un firmante tiene dos claves: una clave pública y una clave privada. La clave privada se almacenará en las credenciales del usuario, que deberán estar disponibles a la hora de realizar la firma.
La clave pública se almacenará en el certificado del usuario, que deberá estar disponible para que los destinatarios validen la firma. La información sobre los certificados revocados se encuentra en las listas de revocación de certificados (CRL) y en las respuestas del Protocolo de estado de certificado en línea (OCSP) distribuidas por las autoridades de certificación (CA). La hora de la firma se puede obtener de una fuente de confianza conocida como Autoridad de marca de tiempo.
Certificar documentos PDF
Puede proteger un documento PDF certificándolo con un tipo de firma concreto denominada firma certificada. Una firma certificada se distingue de una firma digital de las siguientes maneras:
Debe ser la primera firma aplicada al documento PDF; es decir, en el momento en que se aplique la firma certificada, cualquier otro campo de firma del documento debe estar sin firmar.
Solo se permite una firma certificada en un documento PDF. Si desea firmar y certificar un documento PDF, deberá certificarlo antes de firmarlo.
Después de certificar un documento PDF, puede firmar digitalmente en los campos de firma adicionales.
El autor o el creador del documento pueden especificar que el documento se puede modificar de determinadas formas sin invalidar la firma certificada.
Por ejemplo, el documento puede permitir rellenar formularios o hacer comentarios. Si el autor especifica que no se permite una modificación determinada,
Acrobat impedirá que los usuarios modifiquen el documento de esta manera. Si se realizan dichas modificaciones, como por ejemplo utilizar otra aplicación, la firma certificada no será válida y Acrobat emitirá una advertencia cuando cualquier usuario abra el documento. (Con las firmas no certificadas no se evitan las modificaciones y las operaciones de edición normales no invalidan la firma original).
En el momento de la firma, el documento se analizará para detectar tipos de contenido específicos que puedan hacer que el contenido de un documento sea ambiguo o engañoso.
Por ejemplo, una anotación podría complicar algún texto de una página que sea importante para comprender qué se certifica. Se puede proporcionar una explicación (autenticación legal) sobre dicho contenido.

Verificar varias firmas digitales verifying-multiple-digital-signatures
AEM permite verificar las firmas digitales en los documentos PDF. Un documento PDF puede contener varias firmas digitales si está sujeto a un proceso empresarial que requiera firmas de varios firmantes. Por ejemplo, una transacción financiera requiere las firmas del responsable del préstamo y del administrador. Puede utilizar la API del servicio de firma para comprobar todas las firmas del documento PDF. Al comprobar varias firmas digitales, puede comprobar el estado y las propiedades de cada firma. Antes de confiar en una firma digital, Adobe recomienda verificarla.
Sintaxis: verifyDocument(Document doc, RevocationCheckStyle revocationCheckStyle, VerificationTime verificationTime, ValidationPreferences prefStore, ResourceResolver resourceResolver)
Parámetros de entrada
El siguiente código de ejemplo utiliza DocAssuranceService para verificar los campos de firma de un documento PDF ya cifrado.
