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')
...
