Hi, I have a little issue here. I''m working on an eBook site and need to generate PDFs. I managed it using PDF::Writer and did the trick quite well but now I want to generate PDFs with a password access. After checking on internet, I saw that PDF::Writer encrypt method was removed (for encryption algorithm was cracked or something like that). Had a look at the Prawn plugin but it has no security module and can''t be used to do so. Is there any way to create password protected PDFs with Ruby? Other problem, I want to modifiy the PDF generation to create new PDFs by copying PDF files already existing and adding a front page with the customer name and a little message. I managed read PDF files and copy the content in a new PDF but I''m losing all the format (the result is just a new PDF with the text of the original PDF but with no format...). Anyone know how I can copy a PDF and add this front page?

Anyone know how I can copy a PDF and add this front page?I worked through a very similar set of issues a couple of years ago. Ended up using a system call to pdftk (http://www.accesspdf.com/pdftk/). It''ll do what you need very easily.

Ok, this toolkit seems pretty cool but my problem is that I want todo everything using Ruby, so I need a plugin or something that can connect to ruby in order to do the PDF copy etc using a ruby function...

I agree with Bill. pdftk has been an invaluable tool for me when
working with pdfs, and can easily be wrapped for use in ruby.
Altho you''ll want to add checks to ensure safety of params your
passing to pdftk, and check for errors returned, ..., you could do
something like:
...
def add_user_pw_to_pdf(infile, pw, outfile)
`pdftk #{infile} output #{outfile} user_pw #{pw} 2>&1`
end
def combine_pdfs(infiles, outfile)
`pdftk #{infiles.join('' '')} output #{outfile} 2>&1`
end
...
which you could then call like:
...
add_user_pw_to_pdf(''test.pdf'',
''supersecret'', ''test_with_pss.pdf'')
...
combine_pdfs([''a.pdf'', ''b.pdf'',
''c.pdf''], ''abc.pdf'')
...

Ok, I didn''t understood it could be used with ruby, will check how to do that, thanks again for your help ;) On 20 feb, 18:35, Jeff Lewis <jeff.bu...-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote:> I agree with Bill. pdftk has been an invaluable tool for me when > working with pdfs, and can easily be wrapped for use in ruby. > > Altho you''ll want to add checks to ensure safety of params your > passing to pdftk, and check for errors returned, ..., you could do > something like: > > ... > def add_user_pw_to_pdf(infile, pw, outfile) > `pdftk #{infile} output #{outfile} user_pw #{pw} 2>&1` > end > > def combine_pdfs(infiles, outfile) > `pdftk #{infiles.join('' '')} output #{outfile} 2>&1` > end > ... > > which you could then call like: > > ... > add_user_pw_to_pdf(''test.pdf'', ''supersecret'', ''test_with_pss.pdf'') > ... > combine_pdfs([''a.pdf'', ''b.pdf'', ''c.pdf''], ''abc.pdf'') > ... > > Jeff > > On Feb 20, 3:14 pm, CiriusMex <cirius...-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote: > > > > > Ok, this toolkit seems pretty cool but my problem is that I want todo > > everything using Ruby, so I need a plugin or something that can > > connect to ruby in order to do the PDF copy etc using a ruby > > function... > > > On 20 feb, 16:27, CiriusMex <cirius...-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote: > > > > Thanks a lot, I''m gonna check it right now ^^ > > > > Olivier. > > > > On 20 feb, 15:12, bill walton <bwalton...-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote: > > > > > Hi Oliver, > > > > > On Fri, 2009-02-20 at 11:09 -0800, CiriusMex wrote: > > > > > Hi, I have a little issue here.
