jpdfkit encrypted PDF file can’t be opened because permission denied problem in SUSE and CentOS Linux systems

Posted on

Find if permission denied errors are caused by SELinux for VeryUtils Java PDF Toolkit (jpdfkit) software.

VeryUtils Java PDF Toolkit (jpdfkit) can run on Linux systems, VeryUtils Java PDF Toolkit (jpdfkit) can be downloaded from following web page,

https://veryutils.com/java-pdf-toolkit-jpdfkit

However, we recently noticed an issue where we used the following command line to encrypt PDF files on SUSE Linux system,

java -jar /Encrypt-PDF/jpdfkit_1/jpdfkit.jar /Encrypt-PDF/jpdfkit_1/Manual.pdf output /Encrypt-PDF/jpdfkit_1/Manual-output.pdf owner_pw 123 user_pw 456 encrypt_128bit allow printing

The encrypted PDF file couldn't be opened because permission denied problem, even if we tried to copy encrypted PDF file to another file, we still encounter permission denied problem,

cp /Encrypt-PDF/jpdfkit_1/Manual-output.pdf /Encrypt-PDF/jpdfkit_1/Manual-output2.pdf

After we researched this problem for some days, we sure this problem caused by "SELinux" in Linux system, here is the solution.

SELinux, short for Security Enhanced Linux, is a Linux security module that is part of many Linux server distributions. While SELinux increases server security (despite being created by NSA), it often results in some unexpected access/permission denied errors.

If you get one of such errors on a server with SELinux enabled, and there are no obvious file permission issues, you should check if the issue is caused by SELinux. To check the status of SELinux, run:

sestatus

You should get something like this:

SELinux status: enabled
SELinuxfs mount: /sys/fs/selinux
SELinux root directory: /etc/selinux
Loaded policy name: targeted
Current mode: enforcing
Mode from config file: enforcing
Policy MLS status: enabled
Policy deny_unknown status: allowed
Max kernel policy version: 28

"Current mode: enforcing" indicates that SELinux is running.

To temporary disable SELinux, run:

setenforce 0

If this resolves the problem, and you no longer get "permission denied" errors, it means the issue was caused by SELinux. Re-enable it with setenforce 1 and try to find the root cause.

To help with troubleshooting, you can check SELinux log files located in /var/log/audit/audit.log

Very often, the issue is caused by incorrect security context (also called security label) assigned to the affected files or folders. To view security context that SELinux has applied to files or folders, run one of the following commands (they all display security contexts, just in different formats):

ls -Z or ls --context
ls --lcontext
ls --scontext

To modify the security context, you can use chcon command, i.e:

chcon -R -t httpd_sys_content_t /www/sites

httpd_sys_content_t - Apache Read-Only access
httpd_sys_rw_content_t - Apache Read/Write access
httpd_log_t - Apache log files
httpd_cache_t - Apache caching

or use reference directory:

chcon -R --reference=/var/www/html /www/sites

Capture Printed Documents and Save them to Cloud based MySQL database

Posted on

I need to create a software (preferably IN DELPHI 10.x) that monitors printers and looks for receipts and invoices. It should allow me to configure different businesses and everything should be saved to my hosted cloud based MySQL database.

Now, the critical thing is this: when each business is first configured, the system should allow me to print an initial invoice/receipt which is captured. It should then allow me to define certain fields on the invoice: Invoice Number, Date, Item Number, Description, Qty, price, Discount (if applicable) and total, for each line of the invoice/receipt. It should also allow me to define the total of the invoice and payment. All this will be stored in the cloud database.

After this, the software should run automatically in the system tray, and access be password protected. This config is also stored in the cloud. Whenever anyone prints any invoice/receipt, the software should capture the details and store it in the cloud database.

The final part of the software is the admin part which is installed on a different system. The admin part will allow me to configure each business, and run several reports, which will show details of transactions printed during requested periods, with the option to drill down to the individual invoice details. I should also be able to setup different users to access the admin part with various levels of access.

How can I intercept and capture the content’s of a window’s spool file, and convert this SPL file to PDF file?

Posted on

I have files being printed from a client's computer and would like to intercept and archive the printed file as text or pdf. The client will most likely be using a specific software to print and I do not want to integrate with each of the different software's any client could be using.

Is there a way to intercept the content's of the print job, whether programmatically (python's win32print or wmi, c#, etc) or by converting the spool file (.spl & .shd) that is created in the C:\Windows\system32\spool\PRINTERS directory during print queuing.

Customer
------------------------------------------
All print files in Windows are kept in the folder C:\Windows\System32\spool\PRINTERS, which requires Administrator permissions to access.

The files are in the format of .SPL files, which require a viewer.

As intercepting these files while they are being printed is hard, you may instead ask Windows to keep them after printing, for you to copy afterward. This depends on your printer having the option of "Keep printed documents" in the printer Properties, usually in the Advanced tab.

You can use "VeryPDF SPL to PDF Converter Command Line" software to convert from SPL files to PDF files,

Capture documents from any printer and store them as .pdf

Posted on

I need a program to intercept print jobs from any printer driver on my system (not a single custom one) and store the contents of the print job as a .pdf, .png, or most likey .bmp, do you have a software to do this job?

Customer
---------------------------------------
The company I work for currently uses a black box shipping system. Each morning our shipping manager prints out shipping tickets for his drivers. I would like to save a copy of each ticket printed as a PDF. The action of saving to a PDF should be done behind the scenes.

Note: The PDF copy would be in addition to the hard copy, however, I would like to generate the PDF copy when the hard copy is printed (or directly after if I can use the saved print job).

End Result: The manager prints a hard copy and a PDF gets saved to an archive folder without any interaction from the manager.
