Digitally Signing and Certifying Documents
About the Signature Service
Signature service lets your organization protect the security and
privacy of Adobe PDF documents that it distributes and receives.
This service uses digital signatures and certification to ensure
that only intended recipients can alter documents. Because security
features are applied to the document itself, the document remains
secure and controlled for its entire life cycle. A document remains
secure beyond the firewall, when it is downloaded offline, and when
it is submitted back to your organization.
can create a custom signature handler for the Signature service
that is invoked when certain operations are invoked, such as signing
a PDF document. (See Creating Signature Handlers
Signature field names
Some Signature service operations require
that you specify the name of the signature field on which an operation
is performed. For example, when signing a PDF document, you specify
the name of the signature field to sign. Assume that the full name
of a signature field is form1.Form1.SignatureField1.
You can specify SignatureField1 instead of form1.Form1.SignatureField1.
a conflict causes the Signature service to sign (or perform another operation
that requires the signature field name) the wrong field. This conflict
is the result of the name SignatureField1 appearing
in two or more places in the same PDF document. For example, consider
a PDF document that contains two signature fields named form1.Form1.SignatureField1 and form1.Form1.SubForm1.SignatureField1 and
you specify SignatureField1. In this situation,
the Signature service signs the first signature field that it finds
while iterating over all the signature fields in the document.
there are multiple signature fields located within a PDF document,
it is recommended that you specify the full names of the signature
fields. That is, specify form1.Form1.SignatureField1instead
You can accomplish
these tasks using the Signature service:
