PDF encryption question

Hi, I was wondering if it was possible to encrypt pdf files with preview in such a way where someone can open the document and print it without needing a password, but not copy or change anything else.
It seems to be an "all or nothing" where either everything is encrypted or nothing is. All I want to be able to do is control whether someone can copy or change anything, but still be able to open and print.
Thanks in advance to anyone who can point me in the right direction with this!

The full version of Acrobat from Adobe allows you to set these various security options on a PDF.

PDF Encryption. How can I encrypt a PDF via the Crystal Report's Export?

Hello,
Is there a way to encrypt PDF files created via Crystal Report's export feature? We need to have such PDFs encrypted so that end users cannot copy information from them (files would be read only).
I have researched in these Forumns and the old Business Objects' forums but could not find information on the topic. Crystal Report's online help does not provide any information either.
Any help is greatly appreciated

SAP 4.7 Encryption questions

Dear SAP on i5 community,
We are running SAP 4.7 and i5 OS 5.3.0 and have the following questions about how encryption works;
Encryption questions
1. How do we determine precisely what encryption algorithm is used to encrypt credit card data in our R/3 system?
2. How are the encryption keys for this algorithm generated or provided?
3. How and where are encryption keys for this algorithm are managed?
4. Is there a way to change the encryption keys?
We look forward to your replies...Thank you!
TMM

Hello Tim,
You could take a look at the following blog and the Notes refered.
Enable Credit Card Encryption
If I am not mistaken...
1. Decided by SAP already
2. You generate the keys through SAP transactions (details in Notes and blog)
3. Keys are saved in a file on the OS level (make sure it is safe)
4. Yes, you can. But all the previous credit cards will be lost.
Hope it helps.
Best regards,
Victor

Printing and Signing PDF Security Questions

Hi,
I noticed one of the PDF security features for Acrobat 8.0 is to set the printing permissions between "None", "150 DPI", and "High Resolution". However, when I print between two PDF's with 150 DPI and max resolution, I honestly can barely notice the difference between the two (the 150 DPI is "slightly" worst, i.e. letters are slightly more jaggedly). I was wondering is this normal, as I was hoping the lower setting would make the printout hard to read, not just a "quick-print" (I used a Laser Printer with 1200 DPI). I don't mean to make a big deal out of it, but I personally do not think this a very useful feature from a security standpoint.
Secondly, I'm having trouble creating signable PDF's. I basically want the file to only allow a user to sign, and nothing else, so I set the "Changes allowed" to just "filling in forms and signing existing signature fields". But doesn't seem to work, because instead I have to set it to allow "any except extracting page". Only then can I sign the PDF, but then this also allows it to be changed (which I don't want). Is there something wrong with what I'm doing? Any help is appreciated!

It's a very common question, and as Michael says there's not a lot you can do. Even doing the imposition yourself is unlikely to help, as most commercial raster image processors (RIPs - the software which turns your document with its fonts, graphics etc into the pattern of dots needed to physically generate the image on the printing drum) need unencrypted files.
If the print shop has an ad-hoc workflow which supports encryption (such as printing direct from Acrobat in the way desktop users do), there are plugins for Acrobat to handle the page imposition; but it's not something native to the application and the printer will have to give you very precise directions as to what layout to create. Many print shops won't entertain that idea unless there's an overriding commercial reason, as it's too much hassle for them to deal with errors in the client plates. Worth asking, but I doubt they'll agree to it.
Given the need to send unsecured files to an external contractor for printing, your "protection" is in the form of the contract, not digital encryption. The former can be settled in court if they break the terms, the latter can be bypassed in ten seconds and you'll probably never know. If the files are truly too sensitive to send to anyone, it's time to get yourself a laser printer - these days the machines many local print shops rely on are in essence a color photocopier, and you can rent them for about the same price.

PDF Encryption

Reading through the 1.7 PDF Reference guide looking at the "Computing an encryption key" and I'm not sure how to translate step 7 to code. It says: "Finish the hash". Can anyone shed some light as to what this exactly means?
Also Here's some pseudo code for the steps. Can you correct me if I'm off base?
MD5(TrimTo32Bytes("User Password string" + "[hard coded bytes]")) + MD5("Owner Password string") + MD5("Massaged Permission value: like 0010") + MD5("Document ID string")
Does Step 7 mean to MD5 hash the resulting value of steps 1-6? or just to concatenate them?
Thanks.

So the MD5 method's argument is a concatenated array of each of the values from the first 6 steps?
Also a further question about the document's ID value. Step 5 quote:
5. Pass the first element of the file’s file identifier array (the value of the
ID entry in the document’s trailer dictionary; see Table 3.13 on page 97) to the MD5 hash function. (See implementation note 26 in Appendix H.)
If this is my ID: /ID[<C21F21EA44C1E2ED2581435FA5A2DCCE><15349106D985DA44991099F9C0CBF004>]
Do we us the literal characters C21F2... or do we convert each pair from hex into a integer array?
C2 1F 21 EA 44 C1 E2 ED 25 81 43 5F A5 A2 DC CE
194 31 33 234 ....
Thanks.

Converting from PDF directly to Java Objects/XML (and PDF format questions)

Hi,
I posted this originally in the Acrobat Windows forums but was told I might have more luck here, so here goes:
I am desperately trying to find a tool (preferably open source but commercial is fine also) that will sit on top of a PDF and allow me to query it's text for content and formatting (I don't care about images). I have found some tools that get me part of the way there, but nothing that seems to provide an end-to-end solution but is quite lightweight. My main question is WHY are there so many tools that go from PDF to RTF, and many tools that go from RTF to XML, but NONE that I can find that go PDF to XML.
To clarify, by formatting I simply mean whether a line/block of text is bold/italic, and its font size. I am not concerned with exact position on the page. The background is that I will be searching PDFs and assigning importance to whether text is a heading/bodytext etc. We already have a search tool in place so implementing a pure PDF search engine is not an option. I need a lightweight tool that simply allows me to either make calls directly to the PDF OR converts to XML which I can parse.
Some tools I have tried:
1) PDFBox (Java Library) - Allows the extraction of text content easily, but doesn't seem to have good support for formatting.
2) JPedal (Java Library) - Allows extraction of text content easily, and supports formatting IF XML structured data is in the PDF (not the case for my data).
3) Nitro PDF (Tool) + RTF to XML (script) - This works quite nicely and shows that PDF to XML is possible, but why do I have to use 2 tools? Also, these are not libraries I can integrate into my app.
4) iText (Java Library) - Seems great at creating PDFs but poor at extracting content.
I don't really expect someone to give me a perfect solution (although that would be nice!).
Instead, what I'd like to know is WHY tools support PDF to RTF/Word/whatever retaining formatting, and other tools support RTF to XML with the formatting information retained. What is it about PDF and RTF/Word that makes it feasible to convert that way, but not to XML. Also, as I found in 3) above, it is perfectly feasible to end up as XML from PDF, so why do no tools support this reliably!
Many thanks for any advice from PDF gurus.

XML doesn't mean anything - it's just a generic concept for structuring
information. You need a specific GRAMMAR of XML to mean anything. So what
grammar would you use? Something standard? Make up your own?
However, there are a number of commercial and open source products that can
convert PDF to various XML grammars - SVG, ABW, and various custom grammars.
But the other thing you need to understand is that most PDF files do not
have any structure associated with them (as you saw when using JPEDAL). As
such, any concepts of paragraphs/sections/tables/etc. Are WILD GUESSES by
the software in question.

PhotoShop CS2 and PDF Presets question.

Hello,
I have installed the recent free release of Adobe Photoshop CS2 on my Win 8.1 PC.
I am creating the artwork for a CD Cover, by using a CYMK template from CD-Baby.
They require that the finished artwork be submitted to them in PDF format, using the [PDF/X-4:2008] preset.
I found that Photoshop CS2 didn't come with this preset, but after searching the web, I came across this forum whereby a user posted a link to a "JobOptions" archive file at...
http://dl.dropbox.com/u/16243351/joboptions.rar
... I downloaded this RAR file and found that there was a file inside called "x4;2008.joboptions"
I installed this preset by the 'EDIT/Adobe PDF Presets/' route, and it seemed to successfully install the preset.
(No errors at least).
Now when I go to save my finished project as PDF, I am given the choice of...
* [PDF/X-1a:2001]
* [PDF/X-3:2002]
* x4;2008
(this is the exact description of each preset).
My only question is, do you think the desired [PDF/X-4:2008] was correctly installed?,
I'm not sure since the naming format is not exactly the same as the first 2 presets descriptions.
Thank you.

thanks for your reply Mylenium.
is it possible that this user preset might not exactly conform to the desired preset I'm after?
is there any way I can get a genuine copy of the factory preset [PDF/X-4:2008]?
thanks.

PDF Encryption using CONTROL File in EBIZ R12 & Decrypting the PDF

Hi All,
We are using BI Publisher BURSTING with R12 ebiz.
We have a requirement to encrypt the file while generating to the filesystem.Then when viewing the File from OAF they went to decrypt before showing to the user.
As per the Documentation , there are some attributes like pdf-security and encryption level .
a) Can we set these attributes in control file while using with R12 ? Is there any documentation available for the same ?
b) Once we encrypt the file , Can we decrypt the file also , any documentation available for the same ??
Regards,
Vamsee.

I can't recommend a solution for that. Tell your management team that this is unnecessary. The file system should be secure, if it's not someone on your unix admin team is in big trouble......
I mean based on that logic all output files should be secured. By the way OAF is secure too so this really unnecessary as well. If the files need to be secured by a particular user, encryption is still a bad idea. You should just generate a relevant report for the user. Thats how we do security in the apps my friend.

Preview PDF encryption is broken in Yosemite

I correct documents saved and distributed as PDF's. They contain personal information and have to be encrypted. In Maverick, and using preview, i could always print to pdf, choose to encrypt and assign a password. Then I could email the document. Now preview will not encrypt. He help command returned instructions to use the "export" command and then choose encrypt. The check box to activate encryption slightly darkens but does not √. Then saving the document does not produce a protected document.
This has been going on for some time and I had hoped todays update would correct this but it has not. Anyone have any ideas?

Please read this whole message before doing anything.
This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
Step 1
The purpose of this step is to determine whether the problem is localized to your user account.
Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
While logged in as Guest, you won’t have access to any of your documents or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this behavior; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
Step 2
The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Please take this step regardless of the results of Step 1.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of Steps 1 and 2.

PDF displays question mark font

I'm trying to study for an exam, but am having trouble viewing certain PDF files. It displays a box-enclosed question mark font. Up till a few days ago, I could read them just fine, but then I ran Onyx and since then I get the weird font. I've tried opening in Preview, Adobe reader, Skim, and in my browsers and they all do this. Can someone please help me out? Thanks

Hello belgremoo, and a warm welcome to the forums!
Sounds like a munged Font or Font Cache.
Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, it will try to repair your Disk Directory while the spinning radian is happening, so let it go. Reboot when all done, it clears Font Caches as well.
Start with Font Book in Applications, Validate Fonts first, if that doesn't fix it then move all your new fonts to a different set & leave only these in the Main set...

Creating a Fillable/Savable PDF: simple question?

Hello-
I'm new to Acrobat and LiveCycle Designer. I have just created my first form with fillable fields in LifeCycle to send to my company's clients for them to fill out, save the form with their responses in the fields for their own records, and then attach the completed PDF form to an email to send back to us with their responses in the fields. I cannot figure out how to do this. The closest I can come to this is putting a "Submit by Email" button in the form which generates and sends an XML document which is not what I'm looking for; I need the actual filled PDF form sent back to me from the client.
I'm sure this is an easy task, but I have been unsuccessful with figuring this out on my own or finding a post in the forum which clearly answers my questions.
I'm using Acrobat 9 Pro and LiveCycle Designer ES version 8
Can you help me? I'm lost.
Thanks-
Michael

Srini-
Thank you for your response, but I'm afraid I'm somewhat confused.
I opened your attached Send CC Email.pdf file in LiveCycle Designer to take a detailed look at it and found the setting you referenced under the Submit tab:
I understand this location and setting the Submit As field to "PDF".
I then opened your form itself to see if/how the submission would work:
This is where my confusion starts. When I click on the Send Email button in your example document, I only get an error message:
What was supposed to happen?
If you reference my original post, I'm looking for a way to create a PDF the user may 1.) Save electronically with the PDF document's fields filled for their own records and 2.) send the completed document back to my company with their responses.
I don't understand how your suggested solution is supposed to work to allow me to accomplish these two objectives.
What am I missing?
Thank you again-
Michael

Credit Card Encryption Question

Question from my customer (on EBS 11i):
I have a question about the Visa VCF 4 Transaction Loader. We are working
on automating this process and have installed a secured storage area to
hold the file. It is my understanding that the bank is going to send us an
encrypted file.
Is the Visa VCF 4 Transaction Loader can process a PGP encrypted file?
Your help is appreciated - thanks!

The answer is that you do not store the ciphertext in the card number field. You create a reference number which is 25 bytes long that substitutes for the card number, and is stored in the card number field. The reference number, in turn, is also stored in a custom table with the ciphertext. The reference number is a unique key to that table.
You then create translation routines to encrypt/decrypt the ciphertext based on the reference number that you stored. These routines would be passed the card number field, which contains the reference number. The input parameter list for these routines are standard. The routines that do the encryption/decryption are configured to be called at the appropriate times.

How to disable a Preview PDF encryption?

I password protected several preview PDF's of mine and I can open them since I set the password; but I want to remove the encryption so they are no longer password protected. . . and I can't. I also can not find any information on this in the Preview Help.
Am I forever going to have to enter my password each time I want to open these files now?
I am the administrator of this machine. I encrypted the files and don't want to rescan them all to regain non-password file access. Help!
iMac Mac OS X (10.4.7) Intel Based Core Duo

I believe you have to open, select Copy, then do a New From Clipboard and save the new file normally. I tried the Password... option from the File menu, but it didn't allow a resave (tried both the Password for the document, and my own admin one, neither seemed to have any effect).

Firefox 19.0 pdf viewer ignores pdf encryption - how do I get it to honor the encryption?

I encrypted a pdf with Adobe Acrobat so that the document's text couldn't be copied. However with the new Firefox pdf reader, the reader completely ignores this encryption so that the document's text can be copied.

I can confirm that problem: http://www.jeffersonscher.com/forumshots/no-copy.pdf
I guess the "security" offered by this feature is not very good if it's up to the viewer to honor it!
You might want to file a "bug" for this (you could do that on https://bugzilla.mozilla.org/enter_bug.cgi -- that's a new registration, separate from this forum). If you do, please note the number here for reference.

Animated Text In Interactive PDF, also question about SWF distribution

Hello Forum.......first post, so hi to everyone
I have created a indesign cs5 document that has some animated text flying in from the left upon mouse clicking, if i export it to a SWF it works fine but if i export it to an interactive PDF the text is already in place. Is it possible to have animated text in an interactive pdf?
Another question I have is regarding swf files, i need to create some presentations for our sales guys to run on their lap tops while out at clients, when i export it you get the resources file and the swf file....rather than just dropping these into a folder on their laptop is there a slicker way to package it in some kind of projector file.
It would also be nice if in the future I could put the presentation onto a CD and have it auto launch the presentation.
If anyone could give me some basic pointers it would be appreciated.
Thanks
James

Hi, George.
Thank you for your help and reply.
It seems that the Lightbox effect may be complicated to achieve with Acrobat in a relatively simple way. Is it possible to accomplish a similar effect using InDesign CS5 and Acrobat Pro 9 ? I would like to click on certain elements of my PDF document (images or text) and have a window of a pre-specified size (approximately 800 wide x 600 high) open in the center of the screen.
Can I do this in InDesign ?
One other things I noticed is the ability to embed html code in Acrobat. Can this be used to accomplish this effect ? Can a window be opened in the center of the screen triggered by a button in a PDF file so that this window functions as a browser and displays another document downloaded from web address (file located on a server) ?
Thank you again,
Joe.
