Before you can implement digital signatures with Oracle BI Publisher output documents, be aware of the following:
A digital ID obtained from a public certificate authority or from a private/internal certificate authority (if for internal use only). You must copy the digital ID file to a secure location of the file system on the server that is accessible by the BI Publisher server.
Use of digital signatures with Oracle BI Publisher output documents has the following limitations:
Only a single digital ID can be registered with BI Publisher.
Only reports submitted through BI Publisher's Schedule Report Job interface can include the digital signature.
The digital signature is enabled at the report level; therefore, multiple templates assigned to the same report share the digital signature properties.
