Encrypt PDFs In Access 2000

My Access 2000 application is generating a PDF from a snapshot of a report using ReportToPDF.

After I have the PDF fil开发者_运维知识库e generated, I am converting it to binary and saving to MS SQL Server. I'm looking for a way to encrypt it before I save it to the server.

What are my options as far as encryption?
