Free S/MIME certificate to digitally sign .pdf with Acrobat Reader

Good morning,
does anyone have idea where to obtain free S/MIME certificate for personal use and TRUSTED by Adobe Reader to digitally sign documents with own digital signature ? (Comodo S/MIME certificates released by GlobalTrust https://www.globaltrust.it/modulo_reg_smime.asp are free but aren't trusted automatically by Adobe)

Thanks Ben,
Unfortunately, that video is for acrobat X or above and I cant find the "save as reader extended" option in Acrobat Pro 9.
Can this be done from this version?
Thanks again
Matt

FF 19 for Mac. changed preferences to open PDFs with Acrobat Reader. Now when I click on a pdf link, an about:blank FF window opens (pdf then opens)

The change in preferences opens the pdf appropriately with Acrobat Reader, as desired, but before it does, FF opens a brand new blank window (about:blank). How can that action be stopped?

Yes, I mean the eternal application.
Ctrl-click does open the dialog, but that does not cause new/blank FF window to show up.....however shift-click opens the new/blank window, then opens another FF window with a "New Tab" heading, then opens the pdf with Acrobat Reader.....
If open the dialog and select "open in new tab" (open in Acrobat Reader is not an option), a new tab is opened, and the the pdf come up in Reader (without opening a new FF window). In earlier FF, it just opened directly in Reader (or acrobat) without opening a new tab or window.
Thanks

Form edit a signed pdf with Acrobat X

I would like to know how to convert an already signed pdf into a form and add more fields to it, please.
I know Acrobat 9 can do this, but X cannot.

I'm afraid so. My best bet is to pdf-print it and insert fields again. The problem with this is that whatever other field/bookmark gets lost.
I find this puzzling because Acrobat 9 allows playing more with the fields, and if doubt arrises, then you can always highlight the fields. Anyhow, thanks for the reply and I hope the guys at Adobe get something effective for every instance.
cheers,
Alex

Open PDF with acrobat reader not preview

Hi everyone:
I have been creating cross platform projects for a while now.
I just noticed that opening PDF from director tend to open up in
"preview" not in Acrobat. Is there a way I can tell my Mac project
to open the PDFs in Acrobat, if Acrobat doesnt exist then open them
in "preview." On PC they open in Acrobat (I guess this is due to PC
not having anything that can read PDFs naively.)
By the way, I create the projects on PC, and then test them
on the Mac.
thank you,
Rafael.

Is this how it is supposed to be on Mac? Maybe I am just
asking something that I outta know...(like PDFs only open on
Preview on Macs?)

Acrobat 9 Pro - Add watermark to digitally signed pdf?

Greetings,
Is there a way to add a watermark to a digitally signed pdf using Acrobat 9 Pro? I was able to do this using Acrobat 8, but Acrobat 9 restricts this change.
Invalidating the signatures is not an issue as the watermarked copies would be considered uncontrolled.
Thank you.

A - if you add XMP-based metadata (which has bene the preferred method of metadata since PDF 1.4) in "append mode", that will not invalidate any signatures on the document.
B - Yes.

Where should the Green Tick get displayed in digitally signed pdf files in whom the Signature has been validated ?

I have Windows 7 & Adobe 11 installed on my P.C (Apart from other Software) . Recently I downloaded Digitally Signed .pdf files & validated the Signature with Trust Certificates . However , the Green Tick Mark is coming on the left-hand side of a blue panel situated in-between the menu bar & the document . Shouldn't it be coming at the bottom right side of the document (Just above the name of the signatory) ? Is there anyway I can get the green tick to display at the bottom right side of the document or is this just the way the green tick gets displayed in current versions of adobe reader ?
This is the way it gets displayed on the top - left portion of the screen :
However , it does not get displayed in the below manner :

First of all, you need an app on the iPad that can read those files that you want to transfer. Adobe Reader and iBooks are two free apps that will read PDF files. Adobe Reader is much more robust than iBooks as it offers so many more features like renaming files, creating folders, annotating, highlights, etc.
Download Adobe Reader in the App Store. Then read this about file sharing with iTunes.
iOS: About File Sharing - Support - Apple
There are other ways to get files to the iPad, like email, DropBox and some other apps that let you mount your iPad like a flash drive.
This should be helpful as well.

Best practice to verifing digitally signed PDF (signed using localley generated ceritificates)

Hi,
I have signed a PDF using a locally created Microsoft Digital Certificate inside my organization.
As part of the approval workflow, I emailed the signed PDF document to another person in my organization (within the same network) for review and final acceptance.
The issue I'm facing is that when the other person opens the PDF, my signature status will show as not verified. Even though, I have created it while I'm connected on the network.
What are the steps that the other person need to follow so (s)he can verify locally generate digitally signed PDF either manually or in an automated manner?
Is there a server-side tools provided by Microsoft to do the verification automatically? Or, I have to do it manually? Any 3rd party plugins you recommend to ease this verification process?
Appreciate your help,
Yasser

There are several preference setting related to this, depending on what version you're using. For example,
Acrobat 9: Edit > Preferences > Security > Digital Signatures > Verify signatures when the document is opened
Acrobat 11: Edit > Preferences > Signatures > Verify signatures when the document is opened
To fully validate, they will need to add your certificate to their list of trusted certificates or you can set up the Windows Integration feature under Preferences.

Create digitally signed PDFs

Is there a way to create digitally signed PDFs by using the options at the "Print" menu to "Save as PDF" that is available at certain apps ?
If there is no built-in solution by Apple, which applications do you use to digitally sign PDFs ? I searched the discussions, but haven't found an appropriate solution so far...
Thanks for your help

Is PortableSigner a professional tool that really works ?
I have no idea how good it is, and I don't really have any benchmark to compare it to. It's hosted at Sourceforge, which might explain why the web site is a big crude-looking. On the other hand, the site says it's a project of the Municipality of Vienna, so I'd say that it appears it's good enough for at least one government.
My feeling is that a lot of the software at Sourceforge is written for a specific, fairly specialized purpose, and sometimes not a lot of time is spent on the GUI or user-friendly features. But if your purpose happens to meet up with the purpose of the creators, the software can be a life-saver.
Really, I'd say just download it and try it. Only you know if it's good enough or not. And you've got nothing to lose since it's free.

Can no longer digitally sign PDF's with Adobe Reader 9

On our government network some of us have been upgraded to Adobe Reader 9 but now we can no longer digitally sign some PDF files.
People with Adobe Reader or Pro 8 can. Here is a link to one of the documents:
www.unl.edu/nrotc/Nc3065.pdf
I'm also attaching the document.
The document security shows as "Digital signing allowed" in Adobe Reader 8 but "Not allowed" in Adobe Reader 9.
Is there something wrong with Adobe Reader 9 or something we need to change?
Any constructive advice would be appreciated.

I cannot say for sure, but some of the technology the government uses (like the IRS) uses older technology that is no longer support in version 9. For example the IRS tax forms cannot be fillied in and saved using Reader 9. My bet your seeing a similar problem. There is no workaround. You will need to go back to Reader 8 or get Acrobat 9 Pro or Standard.

How to automate digital signing PDF Files in batch

I am trying to find a way to automate as much as possible the placing of a digital signature on a set of PDF documents. We have Adobe Acrobat Pro 8.1 and the machine has MS Office 2003 with Vista Business. Here's a scenario: A set of documents exist in a TO-BE-SIGNED folder, each unsigned. The user uses MS Access 2003 form with a button with VBA code to open and show the first document in the folder. The AcroExch.App, AcroExch.AVDoc, and AcroApp.Show APIs are used to do this. I found code on the internet to do that. Rather than having my client now have to go through all the manual steps to place a digital signature on the document, I want to streamline it to a single click if possible. Right now he has to click Advanced > Sign and Certify > Place Signature > then click and drag > then enter his password > then click sign > then save and close the doc. Can all this be automated? An added bonus would be automatically saving or moving the signed doc to a different folder when it is signed.
I have created a stamp that allows me to add a stamp with just two clicks. Can such be done to add a digital signature? Is it possible to add a button to the toolbar to do this? Can it be done in Access VBA using some Acrobat API calls? Another feature I want to include is moving quickly from one document to the next in the TO-BE-SIGNED folder. Like the arrow buttons take you from page to page, can a button be added to the Acrobat toolbar to take you from doc to doc in a particular folder? Or can that be done using VBA and some Acrobat API calls? To maintain the security of the password protection and yet cut down on clicks and keystrokes, I would like to input the password just once at the beginning of the session and have it remembered or applied to all the docs that get signed as long as that session is open.
I've found some software that purports to do much of the above, but they are all very expensive and assume a big business with big bucks. If anyone knows of inexpensive software that will REALLY do this, I'm open to that as well, though I'd like to control the process myself if possible. I consider myself a beginner with Acrobat and using API calls and would appreciate any help anyone can give. Is the above clear and even possible?
PS: I'm new to this site and using SDK. I posted this under Security (thinking digital signatures) and was asked to post it here, which I'm glad to do.
Thanks much!

Our workflow is such that on infrequent occasions, we have a digitally signed PDF file and the doctor wants to append a scanned note to it. In the past, we could do this, but not now. In the past, when we added the scanned doc, we received a message saying that the doc is already signed and asking if we want to overrwrite the doc. If we respond Yes, then Acrobat would allow it and the signature would indicate that the original part of the document was not modified, but that something had been changed--namely, a doc had been appended. The signature indicated that something had changed since it was added, but it still allowed the append. The signature would have an exclamation point in a yellow triangle indicating the doc had been updated since signed. For our purposes, that was okay because we know what the change is based on the original doc and we know what is appended. Now, however, we cannot append at all. The only thing that is different that I know of is that the doc was signed with software that is not Adobe Acrobat, even though the other software uses an Adobe Acrobat self-created digital signature.
I hope I've explained that clearly enough.
Thanks for your help.

Enable Adobe Reader to Digitally Sign PDF created with Acrobat Pro 9

Hi All,
I am trying to figure out how to enable adobe readers to digitally sign PDFs I create. I currently have Acrobat Pro 9.
Customer Support said that I need to save it as a "Reader Extended" format, but I cant find this option anywhere.
Any help would be appreciated.
Thanks
Matt

Digitally Signed PDF crashes Mail and Preview

I've run into an odd situation - if I try to send a digitally signed PDF file using the Mail app or even view that file in the Preview app, those apps crash. The PDF files are created in Adobe Acrobat Pro version 9.1.0 (for the Mac). My Mail and Preview apps are right up to date.
The same PDF file still opens just fine in Adobe Acrobat. If I create exactly the same file, but don't go through the digital signature step, the files open (in Preview) and send (in Mail) just fine.
Anyone else run into this problem and/or have a suggestion on how to avoid it?
(P.S. By "create", I mean I have printed to the "Adobe PDF 9.0" print driver, which creates the base PDF file. Then I have also "secured" the file by requiring a password be entered to change anything. The final step, which seems to be causing the problem, is digitally signing the file.)

The problem may be related to asking Acrobat 9 to output a file format "compatible" with older versions -- along with adding security.
If you check the Console log, I think you will find that the "mdworker" task is also crashing -- even when you open the file successfully with Adobe Reader. I presume this is Spotlight trying to index the file.
Safari will also crash when attempting to view such a PDF. It puts out a Console message indicating invalid AES block size or some such. Presumably this is related to the 128 bit AES security in the PDF file. Using 128 bit RC4 results in a file that doesn't crash Preview, but the document content is garbled by Preview so it's just as bad.

Can I open reader and digitally sign pdf in flash?

First off let me say, I have 0 experience with Adobe Flash or Adobe Air, so this may be a dumb question or I may not even be asking in the right place. I currently have an application which uses Adobe Reader to digitally sign PDF files. The PDFs are displayed inline within a webpage. The user must use Adobe Reader because it needs to be FIPS 140 certified. The issue we are running into is with browsers like Chrome and Firefox bunding their own PDF reader, it brakes our application. I am looking for a way to force users to use Adobe Reader. From reading on the web, it looks like this isn't really possible and we are at the mercy of the PDF plugin the user has installed. The idea I thought of, though, would be to write an Adobe Flash application which would display the PDF. I am hoping doing it this way, I could force the use of Adobe Reader and not the PDF plugin of the browser. Does anyone know if this will work? And if it does, will I have all functions of Adobe Reader available (specifically digitally signing)?

for a web based app, you can't easily display a pdf in flash. even for an air app (or any other platform), you can't force anyone to use adobe reader (especially, because not everyone has adobe reader).

Problems printing a digitally signed PDF

Hi
I'm having problems printing a digitally signed PDF on a dell 968 AIO printer. It works fine on the a majority of printers but we have had reports of issues with other models as well as the dell printer.
The PDF prints fine when opened in Adobe Reader 9 (blue bar appears at top to indicate signed pdf).
When opened in Adobe Acrobat 7 on the same PC the first pages prints correctly but the rest of the pages print only a few lines in a huge font and the characters are backwards.
The pdf does not always open in reader when accessed through the web it will sometimes open with acrobat is there anyway to control this?
Does anyone know why this maybe happening?
Thanks
Claire

Thanks for the reply Mike. I think I've got a little further with this problem now. There seems to be a problem printing the signed PDF in adobe reader 7 as well as acrobat 7.
I have uninstalled acrobat from the machine but the problem still happens with reader 7.
Does anyone know if reader 7 and below has any known issues printing signed pdf's. It works fine on 8 and above.
thanks
Claire

Digitally signing pdf documents

We want to digitally sign pdf documents that are generated in the printing service / AS. (rwclient is used on the client machines to access the printing service.)
The digital sign should be on all generated pdf documents, with no intervention by the end users. The digital sign should hence be on behalf on the organisation, not the individual user issuing the pdf dokument.
In addition we would like to lock the pdf documents in order på prevent manipulation of the content.
Any surgestions on how to achieve this?
Regards

Hello,
You can create your own destination .
An example is available on OTN :
