Adobe encrypted pdf not downloading

    Hi
    I have pdf ebooks added on my site for sale. When I add a normal pdf book it is downloaded without any issue upon check out. Recently I added password protected pdf version of the same books. These were encrypted in Adobe using a password to prevent copy and paste. (To open and to print password is not required)

    Unfortunately when downloaded via shopping cart these only download a single blank page both on test mode and live mode. If I go to media on WP these books open normally.

    When replaced them with normal non encrypted books again it will download the full book.
    So it appears that Woocommerce dosn’t allow the encrypted book to be downloaded properly.

    I would be grateful if somebody could shed some light on this or advise me on a workaround please.
    Many thanks
    Harsha

  • Hi there,

    To take a better look, please provide the following:

    * A copy of your site’s System Status. You can find it via WooCommerce > Status. Select “Get system report” and then “Copy for support”.?

    * Error Log: Share a copy of any fatal error log found under WooCommerce > System Status > Logs (if available).

    Thanks.

    If I may pipe in here… It looks like you have the WaterWoo PDF watermarking plugin active, and that could be an important piece of the puzzle here. If you are trying to run WaterWoo PDF on an encrypted PDF that will not work, the plugin does not include libraries to unencrypt the PDF nor have you provided credentials.

    Make sure to exclude that file from watermarking. In the free version the only way to do that currently is to list the files you DO want marked in the settings textarea, and omit that file in the list.

    Hi Little package
    Thank you for your input. That could well be the case. I will try that and get back to you.
    Thanks again
    Harsha

    Easier testing would be to just deactivate WaterWoo for now. ??

    It in deed ease the case when I deactivate waterwoo file downloaded successfully.
    I guess now I will have to choose between two options. prevent copy paste or watermark.

    Thank you very much for both of you for your effort.

    Be safe

    Harsha

    There are more options than that, but you can keep it simple if you like. ??

    WaterWoo requires PDFs be un-passworded, un-encrypted — so that they can be parsed and manipulated. Check the FAQs. FWIW the premium version of the plugin will password and encrypt them for you while watermarking. But neither plugin – nor any plugin yet on the market – will allow for encrypted PDFs. For now, you could try using this code in your functions.php file (or by using the Code Snippets plugin, frontend) to let the unencrypted file pass through despite errors the encryption causes with TCPDI. 

    function my_serve_unwatermarked_file() {
    return true;
}
add_filter( 'wwpdf_serve_unwatermarked_file', 'my_serve_unwatermarked_file', 10, 1 );

    This function allows PDFs that fail watermarking to squeak through to the customer so obviously use it cautiously. I will be adding some parameters for the next release so if you’re interested in using it keep an eye. Any further discussion please open a ticket in the WaterWoo forums here. Thank you.
