328203 PDF Merger + Encryptor + PHP

Hello,

Please read the requirement very carefully. And bid only if you are confident of providing a robust solution.

We have tried many ready made libraries such as pdftk etc. but they are too much server resource intensive.

We are looking for a standalone library or code with the following requirement.

1.. Must be lightweight and easy to use

2.. Must be less server resource intensive. We are expecting at least 10-20k visitors / members using our system. And we have a 8 core server with 6 GB RAM. Currently with PDFTK our server load goes above 50 with just 500 pdf processing at a time

3.. Should be able to merge 2 PDFs eg. take page 1 from other PDF and merge with current PDF at page #4

4.. Should be able to set 128 bit encryption with password i.e. allow only printing and disable copying etc.

5.. Should be easy to incorporate with any other php application.

6.. We are not interested in existing scripts/libraries, we have tried almost all of them.

7.. We own full copyright of the script/library that you provide us and you may not use any part of it for other projects.

8.. You should be able to loadtest on your server.

9.. We should be able to set the PDF info and metadata i.e. PDFProducer, PDFversion, Application, Author, Keywords etc.

We do not work with html->PDF.. rather we will already have a PDF on our server that we need to manipulate

Here is how it works

Exiting [url removed, login to view] -> move to tmp folder -> get 1st page from another [url removed, login to view] -> put it in [url removed, login to view] at page#4 -> 128 bit encryption -> save [url removed, login to view]

I repeat we need a robust solution that even if there are 20k visitors accessing our application at once should not compromise the server.

If you have any question please PM me.

Thanx

.
