Find password protected PDFs
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
I have a large number of PDFs and would like to find the ones that are password protected.
Tools like pdfinfo can detect password protection but do not have a specific exit status to script this process:
# pfdinfo pwprotected.pdf
Command Line Error: Incorrect password
# echo $?
1
# pdfinfo broken.pdf
<some error messages>
# echo $?
1
Are there any tools that can be used to easily identify password protection on pdfs? Otherwise I can still grep for the "Incorrect password" line and fix up my own script.

I think you can do something like;find -type f -iname *.pdf -exec grep -alP 'R/Encrypt d+ d+' {} ;Though, I'm not sure how performance efficient that is.

@1lastBr3ath that comes with mostly false positives for me, but thanks anyway. I will probably just shellglue something with pdfinfo.
