Dear HikaShop team,

We are currently using the PDFSubscription and PDF serial plugin to generate and send personalized PDF tickets to our customers. This works very well for our needs — thank you!

We would like to know if there is currently a way to secure the generated PDFs against editing or modification. Specifically, we're interested in features such as:

Disabling editing of the PDF content
Restricting copying or modification
(Optionally) setting a password for changes[/li]

If this is already possible using the existing plugin or through template customization?, we would appreciate some guidance or an example of how to implement this.

If this functionality is not yet supported, would you consider adding it in a future version of the plugin? We believe it would be a valuable addition for many users who wish to protect the integrity of their generated documents.

Looking forward to your feedback.

Best regards,
Lumiga

Kind regards,
Lumiga

Hello,

It requires a specific development in the plugin in order to add such feature.
It is possible to set the protection in TCPDF. For FPDF it requires to add an extra "plugin" for that.
Since the "PDF Serial" plugin can use both libraries, handling the "protection" should be available for the two implementation.
Unfortunately, it is not possible to do so via an override ; if you want to add it yourself, best would be to "duplicate" the actual plugin and force the usage of TCPDF (which is easier for the protection support).
