walt.farrell Posted August 7, 2020 Share Posted August 7, 2020 To possibly help others who don't speak German, here that is in English: Here's what Acrobat Reader says about the document's properties: And here are the security details: I'm not sure what aspects of that Publisher can't handle. Acrobat Reader and the PDF reader in Firefox open it just fine.

MikeW Posted August 7, 2020 Share Posted August 7, 2020 It's that it is password protected. With the password restriction removed, it will open in APub just fine. This is not a bug. Quote Link to comment Share on other sites More sharing options...

Thank you, Walt and Mike, for your comments. That's what also confuses me a bit. Firefox and Foxit Reader open the file just fine without the need for entering a password. Scribus also seems to be able to import it successfully. Quote Link to comment Share on other sites More sharing options...

How else would someone fill out a form? Ok. I'll remove the password and open it in APub... Quote Link to comment Share on other sites More sharing options...

Garfield Posted August 7, 2020 Author Share Posted August 7, 2020 Well done May I ask how you were able to remove the mysterious password protection? Does one need to have an Adobe license for that? By the way, I got around the problem by simply printing the PDF with Foxit Reader PDF printer (which might not be the best approach of course).

Your method generally works fine. I use one if a couple applications to do it because there are methods for actually encrypting that requires a more brute force method. 2 minutes ago, walt.farrell said: Thanks, Mike.

I dunno what, if any, APub's capabilities are for password/security is. I never pw protect a pdf. Quote Link to comment Share on other sites More sharing options...

It has no capabilities to password protect a PDF, and I'm not sure if it can Open a PDF that is password protected. I was mainly curious about whether you kept the encryption (which is separate from the password, from what I can see in the PDF properties), since it was the encryption that Publisher was complaining about.

MikeW Posted August 7, 2020 Share Posted August 7, 2020 If APub cannot open for editing a pdf that has a user password, I seriously doubt it could open a pdf that is actually encrypted via 256/512 encryption--which is what is used for an open password. Even a brute force attack on such a password can take from hours to weeks (or more) to break the encryption password. As far as I know, nothing can open such a pdf.

Staff Jon P Posted August 11, 2020 Staff Share Posted August 11, 2020 It's using an encryption method we don't currently support. I've logged it as an improvement. Thanks! Quote Serif Europe Ltd. - www.serif.com Link to comment Share on other sites More sharing options...

Gigatronix Pete Posted April 29, 2021 Share Posted April 29, 2021 Hello @walt.farrell@Jon P I have been opening our company's pdf's in Affinity (to amend) for the past couple of years since we started using the product & they were all password protected. My boss even remarked how pointless it was us putting passwords on them if it's this easy to open them using Affinity, but it was very useful More recently I've had to type the password into the PDF Options box (image 1) to be able to open them ...which was ok & still usable. I've just tried to open some today (first time in a few weeks) & now they are all coming up with the "This file uses an encryption method that is not supported" as you guys have chatted about above. Do you have any idea why Affinity has just decided to stop letting me open our own pdfs? To my knowledge we haven't changed how we create pdf's/passwords in many years. I have been updating Affinity as the new versions come out & am currently using 1.9.2.1035 so I don't know if that's anything to do with this scenario? Cheers in advance Pete Quote Link to comment Share on other sites More sharing options...
Staff Jon P Posted April 30, 2021 Staff Share Posted April 30, 2021 Hi @Gigatronix Pete, Off the top of my head i don't think anything changed pdf encryption wise in that version. There are still some encryption methods we don't support. If you want to upload the pdf here I can take a look Quote Serif Europe Ltd. - www.serif.com Link to comment Share on other sites More sharing options...

That one uses 128-bit AES encryption, which is not supported by Affinity based on my experiments. It's listed as for Acrobat 7 and later, but Affinity seems to support only 128-bit RC4 (Acrobat 6) and earlier.

Arte Posted May 1, 2021 Share Posted May 1, 2021 On 8/7/2020 at 10:50 PM, Garfield said: Thank you, Walt and Mike, for your comments. That's what also confuses me a bit. Firefox and Foxit Reader open the file just fine without the need for entering a password. Scribus also seems to be able to import it successfully. The reason is that the password protection only applies to editing the document, not to opening the document, printing, copying or filling out the form. When I try to edit it in Adobe Acrobat it asks for a password, the same applies to Affinity apps, CorelDraw, Bluebeam and other programs that try to open it for editing or as editable content because they can also generate PDF forms I guess. Because it does not prevent printing/copying it is possible to reprint it to a new PDF and then open that PDF if that gets rid of the password protection. Whether the fillable form fields remain intact is something else, most likely not. Inkscape opens it as a PDF document for viewing, at least it seems that way, and after ungrouping you can change the text content but the form fields etc. are lost so the document is not the same as the original PDF. Meaning the password protection does do what it is supposed to do to some extent, though it can be cracked because PDF password protection is not really bulletproof to put it nicely.

Famppent Posted October 21, 2021 Share Posted October 21, 2021 As i know. Open Password- Enter the correct open password to access the PDF. Permission Password- You can edit, print, copy and export PDF files after entering the correct password. Either the opening password or the permission protection password of PDF can be cracked. This is also a solution for users who suddenly forget the password. Quote Link to comment Share on other sites More sharing options...

About the Adobe, the password on the PDF can only be removed by upgrading to the advanced version of Adobe, it is not free help. If you are interested in free programs, maybe https://www.sodapdf.com/unlock-pdf/ will be what you want, as a free online service website that can remove any known password from the PDF. Or, try https://www.bestpdfpasswordremover.com/ It once reset the complicated opening password on the PDF for me. Not only that, the permission password can also be easily cracked by it.
