Encrypt Pdf using a X.509 certificate

I googled for a tutorial on using a x.509 certificate to encrypt a pdf. But
I did not find any good source.  What is the benefit of using an X.509
certificate version using owner/user passwords ?

I used a self-signed certificate created with openssl.  I got this error:

Encrypt failed with the following exception:
org.apache.pdfbox.exceptions.COSVisitorException: 1.2.840.113549.3.2

Am I missing a dependency (bouncy castle perhaps ) or am I using the wrong
certificate ?

Thanks
