Macro to export to pdf with certificate

[pilatos]

Hi all
I'm starting with macro programming in oo and I would like to know if it's possible to export a sheet to pdf and give it a name automatically and using a certificate, either requested when exporting or predefined by code.
I have found how to export a sheet to pdf but I can't figure out how to sign the pdf using a digital certificate.
thanks.

PDFBox can help you, paired with ooRexx and BSF4ooRexx you don't need to compile java code, just use it straight away.
