progamerz Posted October 16, 2017 Posted October 16, 2017 (edited) Hello, recently i bought an ebook which has an offline app for android phones, i found out the .pdf file but it is currently restricted opening it without password, is it possible to unlock it? The reason i want to do this, is to be able to print as many copies as i want.

Jammer Posted October 16, 2017 Posted October 16, 2017 Google: free pdf password remover online. I think one of those should do the trick.

Already tried, as this pdf is password protected so i can't even view it or anything i will need password to unlock the pdf to do anything with it
Hi G00gle Posted October 16, 2017 Posted October 16, 2017 (edited) Hi, Maybe this link can help you: https://www.google.nl/amp/s/www.howtogeek.com/299457/how-to-remove-a-password-from-a-pdf-file/amp/ It’s also possible with Adobe Acrobat Pro, but I’d doubt you want to pay for the solution. (You should also be able to remove the restricted access with the first option). Edited October 16, 2017 by Hi G00gle 1
Fruity Posted October 16, 2017 Posted October 16, 2017 (edited) If you're on mac open it up on preview, enable thumbnails then just drag the thumbnail to desktop and boosh not protected. If not, send me file and i can do Edited October 16, 2017 by Fruity 1
Zappster Posted October 16, 2017 Posted October 16, 2017 If it's propperly encrypted, then you'll have to brute the password. https://github.com/kholia/RC4-40-brute-pdf 1

Dex Posted October 16, 2017 Posted October 16, 2017 The whole point of putting a password on a pdf file is securing it. I'm pretty sure you're going to have to bruteforce this one. 1
Okabe Posted October 16, 2017 Posted October 16, 2017 Your best bet is giving us the pdf and the apk. Or using John The Ripper to try and brute the password on the PDF TIP: extract strings from the apk and load these into JTR as a wordlist.
