PDF encryption?
Hello list,
I'm using apache-FOP to generate PDF-reports from XML data. These
reports contain enumerations of network information of many host.
To supply a fast and orderly navigation mechanism we use bookmarks.
Furthermore, we use URL's within the PDF-report that point to
external recourses. So far so good...
Because the content of the reports is confidential I use the
buildin 40bit RC4 PDF encryption mechanism with a user and owner
password. Everything works great, except the bookmarks and URLs
won't work anymore after decryption within Acrobat.
When I look in the Bug report of FOP (2004/05/30) is see one entry
that might describe this problem:
"20480|Ass|Nor|2003-06-04|PDF outline texts are garbled when PDF
encryption".
Does anyone know if this is the bug report for this exact problem?
Or is this problem already solved in a recent snapshot release?
Because I'm highly dependent on PDF-encryption and PDF-bookmarks
within the reports, I am willing to contribute, if possible, into
solving this problem. I've mailed Patrick C. Lankswert
(PLankswert@InsightBB.COM) who implemented the encryption mechanism
with the question if he can provide me with more details on how to
realize this. Haven't heard anything from Patrick so far. Maybe
I've used an outdated e-mail address?
Hopefully someone on the list can provide me with more details on
how to get involved, what the exact problem is, or maybe a
workaround for encrypting without loosing the bookmarks etc?
Thanks for your time,
Kind regards,
--

You've found the right bug. I've added a comment when I've fixed the bug
in CVS HEAD:
http://nagoya.apache.org/bugzilla/show_bug.cgi?id=20480
Unfortunately, using a dev snapshot won't help you since FOP 0.20.5 is
based on our old maintenance branch which has been frozen and CVS HEAD
is not ready for production. If you fix the bug for 0.20.5 it probably
won't make it into our CVS.
A work-around is to use a third-party tool to encrypt the generated PDF
files.
BTW, normally, you shouldn't mail any developer directly, but to ask on
this list first.

This is more of an XSLT question that would be better made on an XSLT
list, which you'll find on The FOP Mailing List page [1]. In
particular, you want the XSLT List on the bottom of the page, but
you'll find other good information there which you can use in the
General Information section. Good luck!

p.s. Even better, you may not have to ask the question. The answer to
your question is probably accessible from the FOP Resources page[2] in
Dave Pawson's XSLT FAQ[3]

Parsing string or numbers after x characters
Posted by Julien Barbin <jb...@epo.org>.
Hello
I'm quite new to the fop mailing list so I have no idea if this problem
occurred already and I was unable to find solutions on the web.
My problem is that I receive for example a date in a concatenated format:
Ex: 20041207
And I have to retrieve it in a readable format through my xslt-fo
transformation.
Ex: 12 July 2004
I tried using substring for that, but I don't have any reference character
to look for in order to parse.
Is there a function which parses strings or numbers after a certain amount
of characters directly.
Thanks in advance for those which will respond.
Julien
