Understanding Applying Digital Signatures to PDF Report Output
BI Publisher for PeopleSoft report output in PDF format can be digitally signed to verify the authenticity of the report output that you send and receive, and to validate that the output has not been altered since the PDF was created and digitally signed.
Note:
As of the PeopleTools 8.54 release you can apply digital signatures to BI Publisher for PeopleSoft PDF output only.
This feature digitally signs PDF report output using Personal Information Exchange (PFX) certificates.
