Spire.PDF.Security with licensed Spire.Doc

[demoore80]

I have a licensed version of Spire.Doc

My requirement is to produce a pdf file from an rtf file, then apply Spire.PDF.Security to the pdf file.

Unfortunately, Spire.PDF.Security is not supported by Spire.Doc.

Can I use the free version of Spire.PDF with a licensed version of Spire.Doc to apply Spire.PDF.Security?

Or, do I have to use a licensed version of Spire.PDF?

Thanks!

Dear demoore80,

Thanks for your inquiry.
Kindly note that alone two libraries can't be used in the same project, if you want to use two products or more in the same project, please download Spire.Office and reference the corresponding dlls from it. Also, there is no need for you to purchase Spire.Office, you only need to purchase the product you want.
If there is any question, welcome to get it back to us.

Sincerely,
Betsy
