## How to lock and protect PDF files on a special USB disk or a hard disk? How to protect your PDF files on a USB disk drive?

How about USB stick distribution, how does this work?

"Yes, VeryPDF Cloud DocSafe can be locked on special USB disk, it will read USB Disk's serial number, if current USB Disk's serial number is not equal to predefined USB Disk's serial number, you will not able to view this VPDF file."

I've put a Kingstom USB stick in my computer to test the ability to lock VPDF to USB stick, it's not working.

Program does not provide me with USB neither it doesn't lock VPDF to that USB stick if I manually insert it's ID:

Another question: if I want to lock VPD to Hard disk ID, is there any utility that I can send to customer in order for him to provide me with his HD ID?

Thanks for your message, in order to lock a VPDF file to a USB disk or a Hard disk, you need get the USB Disk or Hard Disk series number first, you may run following command line in a CMD window by manual to get series numbers for USB Disk and Hard Disk,

wmic diskdrive get PNPDeviceID

PNPDeviceID
IDE\DISKHITACHI_HTS725050A7E630_________________GH2ZB390\4&15A50E0B&0&0.0.0
USBSTOR\DISK&VEN_GENERIC&PROD_EXTERNAL&REV_1.14\365644413254395620202020&0

For the report we create emf files, so the can be show on screen and printed without re-calculate all report.

Our problem is convert these files in pdf, we are looking for a library that allow us to takes these emf files and put it inside one pdf.

I see your command line tool emf2pdf,

It works very well with our prints.

Is there a EMF to PDF Converter SDK version for C/C++?

Many thanks,
Customer

int _tmain(int argc, _TCHAR* argv[])
{
string command = "D:\\VeryPDF\\emf2pdf.exe D:\\test.emf D:\\out.pdf";
system(command.c_str());

return 0;

## VeryPDF DocSafe, VeryPDF Cloud PDF DRM Protector, Convert normal PDF files to DRM Protected VPDF files online, View DRM PDF files on iPhone/iPad/Android/Windows/Mac devices

I tried trial version of your product and have several questions!

MAIN GOAL: I would like to protect my PDF book on a user level or group level, so I can add users and/or groups, which will have access to different PDF files - complete book or individual chapters.

• on Trial I can't see backend, what are the options that I can apply to specific users/groups?
• I never managed to lock VPDF to USB ID in case of offline distribution? nor did I find any support for it on your knowledge base
• can specific user open VPDF on PC, MAC, Android... simultaneously or only once on each device
• if I distribute VPDF offline, can I disable user from opening it if I want to?
• if I lock VPDF to specific computer and user replaces that computer with new model, what is the procedure to renew access to VPDF?
• can I host VPDF files on my server or is it better to use your cloud system?
• can users download VPDF offline so then don't have to load VPDF from cloud every time they want to read it? My whole PDF is 300MB+, 7000+ pages.
• what is the procedure to upload offline VPDF to iPhone/iPad devices?
• do the customers have to be online at all times to read secured VPDF?
• can I set user access to more than 1 computer in case of bigger companies, like multiple computers assigned to one account, for example: company buys 3 licenses of my VPDF and they want to use it on 10 devices, but they cannot open VPDF more than 3 times simultaneously?
• can I lock VPDF to IP range, example: 192.168.1.*
• are there any securities for VPDF regarding screenshot software and remote view (virtual machines)?
• after customer buys licence/licences to access my VPDF/VPDFs, is there any automation for providing him user/pass/rights that can be implemented?
• what are total cost per month and per year for such service?

Until now I used PDF to EXE converter, now I want to put PDF online so I can apply changes to PDF for all customers at once. Is there an option to fully test your DRM system for a day or two so I can easily decide if your solution is suitable for my needs?

Thank you,
best regards!

I have ordered a full license for the products "PDF Toolbox Shell for Linux" and "PDF to image converter command line for Linux". I have a Problem with the Registration. I have both tools installed as root on the server, registered with the appropriate keys and then attached via /.profile to the PATH variable. It works as root over SSH. In PHP I call it as a user "www-data", whose PATH variable unfortunately is not so easy to adjust, but which is not further tragic, since I hold there the entire path and call (/ opt / pdftoolbox / bin / pdftoolbox and according to pdf2img) which also works so far. But the registration with the key did not affect the user "www-data", here the trial is still running. For pdf2img I could use the key for the web user (www-data) in the same way (as for root) after logging in via SSH as "www-data". If I want to do the same for pdftoolbox, I get "memory access error". Do you have any suggestions? Thank you very much in advance! Customer ------------------------------------------ Thanks for your message, you may pass your license key to pdftoolbox every time when you call it, for example, /opt/pdftoolbox/bin/pdftoolbox -$ XXXXXXXXXXXXXX /www-data/sample_verypdf.pdf /www-data/sample_testcmd.pdf -merge -outfile /www-data/_out.pdf

You can also call pdftoolbox binary with command line options from your PHP code, for example,

<?php

$strCmd = '/opt/pdftoolbox/bin/pdftoolbox -$ XXXXXXXXXXXXXX /www-data/sample_verypdf.pdf  /www-data/sample_testcmd.pdf -merge -outfile /www-data/_out.pdf';
$answer = shell_exec($strCmd);
