I have a bunch of pdf's I want to remove passwords from. Note that I know the password, so no need for brute forcing. I am working on a mac, so I would like to make an app to remove those passwords.
I have seen apps like wondershare's pdf password remover, so I know it is possible.
Is there a solution/library in the obj-c environment to remove passwords from PDF's?
ok. Here is the easy solution.
Open the pdf with google chrome.
Enter the password.
Print document using ctrl+p.
Choose Save as pdf option.
Done.
I think this would work for you. Both answers seem valid, I personally would opt for the second one.
Transcribed:
do shell script "pdftk secured.pdf input_pw foopass output unsecured.pdf"
I think you are looking for PSPDFkit. See this documentation here Documentation
You can do it in a way by iterating through all the pdf's and unlocking one by one.I am not sure if you are exactly looking for this type of solution, but may be helpful.
Iterate through all the PDf's and create a CGPDFDocument by passing the exact path of the pdf,
there is a method on CGPDFDocumentRef to check whether the document is password protected, which is "CGPDFDocumentIsUnlocked". If it is locked then unlock the file using the method:"CGPDFDocumentUnlockWithPassword".
save the unlocked document to a path and from then on you need not unlock each time you access it.
TNQ
Using Adobe Acrobat 9 Pro:
Open the document by putting the password.
Advanced -> Security -> Remove Security
Save the document
close and reopen with no password.
This is what i tried:-
Open the PDF file.
Enter the password for the first time.
Now to remove password "ctrl+p", then select this "Microsoft Print To PDF".
Then click on print,it will ask for location to save, give the details where you want to save and save it.
Done.
Note:-
To be more precise we don't need any browser for this it can be done in your local system.
Sometime you get some bank documents like form-16 etc, it will be password protected and you will not be having permission to modify due to security reason, due to some reason or might be you are using some organization system, so in that case this is helpful.
Steps to remove password security:
Right-click on the PDF file and select “Google Chrome” from the “Open with” menu or drag any password-protected PDF file (bank
statement) into your Google Chrome browser.
Now go to the File menu in Google Chrome and choose Print (or press Ctrl+P on Windows). Choose the destination printer as “Save as PDF”
and click the Save button.
Provide the file name and the file location and your duplicate PDF file will be saved in the specified location. Now upload the saved PDF
file.

I've been tasked with updating a .xlsm file with VBA that is accessed via the Citrix Workspace application. The previous author has left the company and did not leave behind any further documentation on it.
The VBA is password protected. I've broken and readjusted VBA passwords with a hex editor before, and would gladly try that. Only thing is that the author of this current project also threw in some VBA which prevents the file from being saved as which is then password protected.
Any idea of how I can get through the save prevention VBA? Or perhaps get the file saved as a .zip to my computer?
SOLVED! Despite me flipping "disable macros" and ActiveX components I was still being prevented from saving the file. What I did, however, was navigate to the file's location, did a right click copy, and then just pasted it to the desktop. From there I was able to adjust the file extension to a .zip, and then cracked the password protection via the Hex editor method.
I am looking to facilitate the users of my website with a google-doc like text editor, where the user can write and format text in the context of an A4-page rather than a HTML textbox, which can be saved on server later on.
The idea is that, later I can proceed to print the file on server-side, without asking the user to go through the File->Print from his browser and then re-upload the locally saved PDF, instead I would generate a printable format of the input.
A simple WYSIWIG editor won't do I believe, as it will not be able to edit address fields inside it, but feel free to prove me wrong!
Thanks!
I've got a form that I downloaded, I'd like to prefill some content on the form (this is easy using cfpdfform).
Where it gets tricky is I would like to allow the user to modify the contents of that form, and then somehow have those modified contents accessible to me. I didnt build the source PDF so I dont know how to allow the user to "save" the new contents so they can be read.
Any ideas on where I might start on this one?
You can also use the cfpdfform tag to read/write data to a PDF file which has a form. The important thing is that the PDF document already have the form fields available, or that you add them.
I just recently completed a task where I had to have a user fill out a normal web form, and then create a filled version of an existing PDF document. It worked like a breeze!
I think that depending on what you are trying to accomplish, having the user fill out the data in a web form is less confusing than serving up a PDF and expecting them to save that to update a file on a remote server. Just my opinion, though.

It's possible for users to complete most PDF forms in Adobe Reader, but when user's try to save the changes they get a popup prompting them that the PDF cannot be saved and would need to upgrade to Adobe Acrobat to have this functionality.
Since Acrobat 7 (or possibly) 8 it's possible to create a form so that it can be completed and saved in reader. In Acrobat open your PDF, and select Advanced -> Enable usage right in reader from the menu. This will prompt you to save the form and then anyone using Adobe reader can complete it.
Once that's done you can open the form in ColdFusion, populate some of the fields and serve it up to the user. Once they fill it in, save it and get it back in ColdFusion you can read the contents using the PDF related tags.
Please note: It's currently not possible to set the "enable usage rights in reader" flag from ColdFusion, you need a copy of Adobe Acrobat or access to Adobe LifeCycle server to do this.

How do I programmatically open a password protected PDF. I want to use ruby to open a password protected PDF and read its content.
I would like to know whether its possible and if it is possible guidance on the right way to do it
not sure if you got anywhere with this but pdf-reader supports this functionality.

PREFACE: Yes we're moving away from VSS in the next few months.
One of my web projects contains, as one of its files, a PDF. The PDF on our QA site is being pulled from VSS.
A QA tester recently told me he's being prompted for a password when he tries to open it. VSS says the file I have on disk is different than the one it has, so I updated it, but afterwards it's still being shown as different.
So basically VSS is mangling my PDF and the results are so wobbly that Adobe Acrobat Reader is confused and thinks it has a password.
I've tried adding it as Auto-Detect and as Binary. Same results.
Why does my PDF ask for a password after being retrieved from Visual SourceSafe and how can I prevent it?
Do you have the SourceSafe 2005 Update installed?

The PDF bug was one of the most commonly requested hotfixes: http://support.microsoft.com/kb/925234
I've tried adding it as Auto-Detect and as Binary. Same results.
To be clear, are you adding a version of the file you know is not already corrupted? Even so, there are plenty of other bug fixes on the list above which can cause random file corruption -- try that first.
