This is a good addition, but as the OP says, this is a workaround. Eventually in the future the simple check in Parser::parseContent() should be modified to check if the document actually cannot be read.

        if (isset($xref['trailer']['encrypt'])) {
            throw new \Exception('Secured pdf file are currently not supported.');
        }

It should be taken into account that a future fix for this would obsolete the use of the config option being added here. That's probably the only thing I don't like about this change.

@DivineOmega Are you still with us here?

Hi. Sorry for the delayed response. Things have been busy recently.

I didn't end up actually using this functionality myself. I found that a majority of the PDFs I ignored the encryption check for would actually be parsed as containing no text or limited useful text. I'm not sure why this is and so my workaround here ended up not being useful for my use case.

This library still provides some of the best parsing I've found. My solution was to use an alternative parser if this one detected an encrypted PDF.

@k00ni Can you please reopen and merge this, as in some cases the PDFs are from a predictable origin and are readable but are marked as encrypted. I believe it is up to the caller to test that the data they get is valid.

I am willing to write the test (using test.pdf from #488) and the docs. But first I would need agreement that the merge would be done if those conditions are met.

Thanks.

@unixnut Thank you for your interest. You have my full support. It would be great if we could agree on the following list:

• Create a new PR, with a reference to this one. This way we have a clean start.
• Add at least 2 (very simple) tests: one with new option active and one with not active
• Please add a note to the function header of the new Config options. Something like "this is a workaround, don't rely on it, may change in the future, further information in the following PR XXX" (see comment Add ability to ignore PDF encryption check #632 (comment)) (I can do that, if you want)
• A note in the documentation (I can do that, if you want)
