Methods to secure PDF files against third party releasers

• PDFs from a third-party program causes Windows permissions errors

  I work for a company that has created a software that runs on all versions of Windows and you can create this software PDF reports. I ran into a few people who have our software on a Vista computer and when they run a report creates the file in a location of export and opens on the screen. If it closes the PDF file and run it again, they get an error: could not open file C:\folder\Doc.pdf. Pretty standard error and our usual response to that is, "your windows user doesn't have permissions to overwrite files in this folder." Once they change their permissions, they do not get the error.

  I ran into 3 or 4 of our thousands of customers who are running Vista and get this same error, even if their windows user has full control of that export file and they can manually replace the files in the folder itself. I had to create a simple text doc and crush him, and it replaces without problem.

  Anyone know if there is something that it is Vista that would prevent a 3rd party application to overwrite a file? A PDF file in this case. I've never ran into questions similar to this on XP or 7.

• How to extract pages from a secure PDF file

  How to extract pages from a PDF file secure?

  Adobe would call this hacking and do not allow for discussion in this forum. You should contact the owner of the copyright and see if they are willing to release the password, or a document not guaranteed for you. If it is something done to you, like a bank statement you must notify the Bank how annoying their choices are.

• Research methods save a PDF file in clear text

  Hello

  At least during development, I wish that my PDF to be saved uncompressed files. This format will allow me to grep the files and inspect them. Is there a flag or the utility that will allow me to do this?

  Note: I already know about PDFXML, which isn't what I'm looking for.

  TIA,

  -Ramon

  There is an example in the SDK called "Decompress PDF" that adds a new item to the "save under" list of formats - "PDF uncompressed' that would do what you want.  You could also take the guts of the code and do it yourself before a backup...

• Third-party VPN client

  Cisco ASA is used VPN concentrator and I published that users do not use the CIsco VPN client for instablish a tunnel VPN with the ASA instead they use third-party applications that works when you import the configuration file into it.

  So my question is:

  1-is there a way to prevent this to happen and restrict to use the Cisco VPN client?

  2 - What are the concerns of security to use a third party application?

  Kind regards

  Hesham.Yousry

  There is not a way to avoid this with respect to the third party IPSec client.

  I don't think that there are security problems when using third party IPSec client until it establishes the secure connection.

• can I copy of content impossible when making the word into pdf file conversion?

  When I copy my signature (for paper copies) on a wordfile and I want it to be impossible for third parties to recover from the pdf file.

  How can I achieve this?

  Hi frankv.

  This isn't something that you can do during the conversion process. But with Acrobat, you can apply file security constraints, what would prevent people who look at the PDF of the copy of the content of the PDF file. See Acrobat help | Securing PDF files with passwords for more information. If you do not have Acrobat, we invite you to give it a try. You can download a 30 day trial of http://www.adobe.com/products/acrobat.html.

• A pdf file in Acrobat cloud maybe blocked password?

  I was wondering if we can the password to lock a pdf file that is located in the cloud to Adobe Acrobat? Maybe it's a redundant question, because it is assumed that all the files in the cloud of Adobe are protected in that sense to know the credentials (username and password) to connect to Adobe Cloud?

  Hello

  All files that you have uploaded to Adobe Document cloud are available to you (or the person who signs with the unique credentials: user name & password).  No one else has access to your files in the cloud.

  In addition, you can restrict access to individual PDF documents by setting passwords using the desktop version of Acrobat Professional or Standard DC.

  Securing PDF files with passwords, Adobe Acrobat

  Please note:

  • Acrobat Reader (desktop and mobile) apps don't offer the ability to create password-protected PDF documents.
  • Once the PDF documents are protected by password, you will not be able to make changes (e.g. adding annotations, fill forms) for PDF documents using Acrobat Reader mobile apps (for iOS, Android, and Windows Phone).  There is a limitation in Acrobat Reader mobile apps only.

  Please let us know if you have any additional questions.

  Thank you.

• Anyone know of any way to label a SECURE PDF with the current date when it is opened or printed?

  I tried to add the date in a footer, but which is not updated and I tried to use javascript with a form field, but does not have the javascript code in a secure PDF file.  PDF must be secured in such a way that the content may not be copied, changed, etc..

  Thank you

  Dave

  Another post, I found that allowing the filling form security fields will enable the javascript code to execute.

• What am I missing - it can be difficult to create a PDF file and put in text

  I'm experimenting Acrobat X

  (1) so I want to create a file PDF - ahhh, how is that I need to atually open/import an existing PDF or other document? How do I just start with a blank page. You mean I have to really go and create using another program, or did I miss something, because my definition of creation, is to create, not to modify any other document?

  (2) so that I had a PDF file that I had collected from different sources and added a blank page at the beginning.

  On this blank page, I went to tools | Change the text & objects | Add or change the Tex box. and added a text box. Where can I really format the text, with the exception of the base font and size. How can I make "BOLD" or anything else for that matter. In fact I entered the line, and breaks when I clear the text box, he removed all.

  I looked in the forums, I watched your videos, which ideally stop before explaing the "Add or edit text box.

  I found that I could use the Documents to text editing to change the text that was already there, but seriously its very very and I mean very easy Assembly - it seems to be nothing complicated about this, including any "BOLD", or Itallics. Maybe he has ben that the police was not available, and so I couldn't change the size of the stroke (if that's what is classified as "BOLD").

  Sheesh I have more editing control by using the $ 20 million program, that I bought at another provider, what looks like closely using MS Word and allows me to implement editable forms.

  So what - that I'm missing?  where is the creation, where is the feature? Y at - it another program that Adobe uses to CREATE a PDF file?

  Thank you

  John,

  Acrobat is used to create PDFs from other files. Originally, all files would be printed to the file as a postscript file which would be distilled manually (using Acrobat Distiller). Today, there are two basic methods for creating pdf files. Adobe has simplified things a bit for you that you can print to a virtual printer which will create a temporary postscript file that will be sent to distil for you and create a pdf file. For some programs, such as Microsoft Office programs have a plug-in which will create the PDF directly from the Office program without using the virtual printer to create an Adobe Acrobat PDF file.

  When you have a PDF, the Acrobat program can be used to change the pdf file (create the form fields, write comments, crop the pdf file, combine PDFs etc..). The content of the pdf file must be in paper virtual (or better still stone). You can add emblishments, but not easily change its contents.

• Licenses of PDF files be modified using third-party applications

  I intend on creating editable PDFs (form based) using a third party tool like Foxit PDF editor. I am told that an editable PDF (created using Adobe Acrobat) incur costs of license if more than 500 forms are received from users in return.

  I was wondering if Adobe would still charge fees even if we use a third-party tool?

  Please advice.

  The Acrobat software, licensing restrictions you're referring only applies if activate you reader with Acrobat forms and distribute it to more than 500 recipients. Because you would not be allowing the reader to your forms (since the only software that can is Acrobat and Adobe LiveCycle Reader Extensions), you might not be in violation of the license agreement Acrobat. Note that so that your users to save the form with a desktop version (Win/Mac) of Adobe Reader prior to version 11, the document will have to be activated for the reader. Player 11 and DC, mobile versions of reader and some non Adobe PDF viewers are able to save not compatible PDF Acroforms, but not the forms enabled for the XFA created with LiveCycle name.

  In addition, if you decide that you want to use Acrobat Reader-activation for your forms, if you use Acrobat DC, then there is no licensing restrictions since they were dropped for Acrobat DC. Restrictions apply to Acrobat 8 to 11.

• Security message persistent downloading of email PDF files

  Updates that you have installed the last week did not cause the behavior that you see, so don't "revoke" none of them! I think something was wrong already and install updates only the surface of the problem.

  • 
    Translation: I never had someone to uninstall ("revoke") advise a security update. In other words, the computer must NOT be connected to the internet if KB2957689, KB2957503, KB2957509, KB2939576, KB2957189 and KB2926765 are not listed in the installed updates.
    

  REPOST : Because the computer had a fully functional anti-virus application, installed for several years, there's a chance, but remote, you can see the effects of a 'hijackware infection' and that MSE has never worked correctly.

  That being said...

  Were the emails with PDF attachments sent by people using MS Outlook (not Outlook.com) as their e-mail client?

  If you send an email and attach a PDF file that is saved on your hard disk, you see the same behavior when you open the message received?
  

  If you uninstall Adobe Reader X (v10.1.10) and then perform a new installation of Adobe Reader XI (v11.07) [1] or Foxit Reader, the behavior persists?

  =====================================================
  [1] ATTENTION all pre-selected options for 'drive-by' install unwanted software, third party (for example, that the Google toolbar; Google Chrome)!

  Robear: OK, I'm not updates.

  I can't really ask customers about how they do their email! I've collected PDF documents, I was recently and earlier, and some I downloaded from old newspaper web sites and sent them through several mail clients and browsers and they all show the same problem.

  Your link to Adobe Reader 11.0.7 redirects to a page with 10.1.4 on it, a version earlier than the one I already had. He seems to think of Adobe, I don't deserve to have 11 because my OS is Vista. There are other sites that have, you recommend one, for example. FileHippo?

• Fillable PDF of Acrobat forms do not seem to work with third-party PDF readers. No way to avoid this?

  I wish that adobe would make their more accessible and easy to use PDF forms making them compatible third-party PDF readers. I do extensive PDF forms that have embedded fonts, and they only work with Adobe reader software. Huge problem when there are so many other PDF readers out there. Form is basically corrupt and fonts disappear or is replaced that is not supposed to happen. How to avoid a customer called me to say that the form does not work?

  They ask a Word file at the place where they are able to change fonts, colors, size, etc.. Why Adobe cannot make forms more accessible by allowing the user to change fonts if necessary?

  Also, when I try to add a window where a customer can add their own photos with a bit of javascript and function button, the only eligible image type is a PDF. Why not a jpeg file for more photos are jpeg file?

  It seems to me that engineers do jumps and limits of improvements on programs like Photoshop but kind of not paying attention to the fact of this PDF file are used for current affairs all the time. The PDF format has enormous potential in the place of the market, but the fact that the forms do not work on third party PDF readers and the fact that the fonts in the forms is not modifiable by the end-user in the extended format is a huge problem.

  There's really nothing adobe can do on the functions of the software how not Adobe. The PDF standard is no longer controlled by Adobe, it is controlled by the ISO. Some PDF viewers choose to have no support for forms, some have good enough support, and some (such as preview) are simply malicious. There are a lot of non Adobe software that creates PDF files bad, and that does not almost using Acrobat/Reader. Still, this isn't Adobe can solve a problem.

  With respect, allowing the image with the buttonImportIcon method and the reader formats, I know that sent a feature request for this. Reader 11 is the first release since Reader 5 that supports this, so I have hope for the future. In the meantime, it is pretty easy these days to convert an image in PDF format. Same preview can do.
