Digitally signing with Acrobat 7.10 Pro

Is there a way to digitally sign several/many pdf's?
E.a. bulk wise.
With the Batch tool, javascript or something else.

Hi,
Yes, you could use the Batch tool to digitally sign all of the files in an input folder. Because there is not build-in signature functionality in the Batch feature, you would have to create a JavaScript (which is included in the Batch feature) to find and sign the signature field. My recomendation would be to save the signed file to a separate output folder.

Update 9.1.2 breaks digital signing documents in Adobe 9 Pro on Windows XP

I am able to digitally sign documents using an Aladdin eToken Pro 64k with a fresh copy of Adobe 9 Pro for Windows. However when I update to version 9.1.2 digital signing fails with an "error encountered while BER decoding". Signing still works on Vista and Adobe 9.1.2 Pro. I've checked to make sure none of the settings relating to digital signing changed during the update and none have. Anyone have any ideas on how to correct the problem?

Hi Nick,
First up, there was a small error in my previous post. I said the version of Acrobat (and whenever I say Acrobat I really mean both Acrobat and Reader, but I'm too lazy to type both) that was modified to fix the bug in SHA-1 fallback was 9.1.3, but I really meant 9.3. Sorry about that.
I saw your post from yesterday (http://forums.adobe.com/thread/563601) where you broached the BER decoding error, but in the post above you said signature creation isn't failing any more, so hopefully some update has fixed the problem.
Here's a little bit about the BER Decoding error. During the signing process Acrobat writes the entire file to disk (which is why you always get the Save As dialog as part of the signing process) in the signed state with everything but the actual signature. However, it does leave a hole in the file where the BER encoded cryptographic data will reside once it's be computed and formatted. One thing that is created before the actual signature is the signature appearance. The signature appearance in the form field isn't really the signature proper, but just a graphic representation of the actual signature. The reason that the signature appearance is written to disk before the signature is created is because it too is part of the signed data and must exist before the actual signature is created.
In a perfect world, after the file is written to disk, the cryptographic signature is created and written into the hole in the PDF file, and the signing process completes without any problem. However, if we get to the point that the file has been written out, but during the actual signature creation the process fails, that hole I mentioned isn't filled in. It's not really a hole per se, but a block of zeros that act as a placeholder for the BER encoded data. Because there was some sort of failure and Acrobat didn't get the signed data back from the hardware device what you end up with is a PDF file with a signature appearance, but no real signature in the file. When you click on the signature field Acrobat tries to validate the actual signature, it finds the block of zeros where the signed data was supposed to be, it tries to decode the zeros and gets (as you might well imagine) nothing back and displays the BER Decoding error.
Let leaves us with why didn't Acrobat get the signed data back. When using hardware devices, such as tokens or smart cards, the actual cryptographic signing (the encryption of of the digest with the users private key) takes place on the device. Acrobat (nor any other application) doesn't have access to the private key, which is what makes hardware devices more secure. It's up to the device to sign the data and send it back. If there is any kind of breakdown in that communication channel (which I mentioned in my previous post) the signature creation doesn't reach fruition and you're left with an unsigned file that looks like it was signed because there is a signature appearance.
This is a case where we are providing technically correct, and utterly useless information. It's true that we can't decode a bunch of zeros, but what we should be telling the user is there is no signature (it's kind of like the Matrix where there is no spoon ).
I hope this helps explain what you're seeing. If the the signing process breaks down again please make sure you are using the latest version of Acrobat/Reader and the token software is up-to-date. If everything is current and the problem returns please let me know.

Digitally signing using Acrobat XI and Mac OS 10.9.2- won't let me type signature- the box appears but can't adjust font or any other aspect of text.

I just purchased Acrobat XI pro for Mac. I have OS 10.9.2 When I got to digitally sign, it only allows me to sign using certificate- which does not render a legible name- and is an apple authorization certificate. Or if I go to "type text" the only type showing in the box is Helvetica 12. I can't adjust that. then I put my name in and that's it. It does not look like a signature. I was hoping to insert an image
or at least have it look like a signature.
What can fix this?
Darcy

When I click "place signature" I only have one option.
It asks me "How would you like to create your signature?
The only option available to me is "use a certificate- When I attempt to use another option there are some but they are not available to me."use an image" draw my signature, or type my signature
are not available.
For that reason I went to preferences to see what I could do to change the settings- and all I could do was manage the certificate signature- so that it looks better than it did.
As an aside- after doing that- the document went on and the person couldn't sign because it had an "open password" If you also know about that- that would be great.
This is the only reason I purchased the Adobe XI so I could draw my signature or type it and have it appear as a signature.

Error 2148073513 When Attempting To Digitally Sign In Acrobat 11 Standard

I'm attempting to use Acrobat 11 Standard to digitally sign a PDF document with a 2048 bit certificate from our internal certificate authority, and I'm receiving the following error:
Error encountered while signing:
The Windows Cryptographic Service Provider reported an error:
The requested operation is not supported.
Error Code: 2148073513
The operating system is Windows 7 Enterprise x64. When I remove Acrobat 11 Standard and install Acrobat 9 Standard on the same Windows 7 system, I am able to successfully sign the document using the same certificate that was giving the error with 11. Also we have been using Acrobat 9 on Windows XP with these same certificates for a long time and never encountered issues with digitally signing.
Any ideas of what might be causing this issue?
Thanks in advance
Josh

Hi Josh,
The error message comes from Windows (not Acrobat), but Acrobat 11 is probably asking Windows to do something that it can't. What it is I don't know because the error message is too vague. One thing we can do is to take Windows out of the picture and see if you can sign when Acrobat accesses the digital ID itself as opposed to asking Windows to do the work. This is a two step process, first, export the digital ID from Windows into a file, and then import the file into Acrobat (it's not really an import, but I'll leave it at that for now).
Step 1 - Export the Digital ID
Launch Acrobat
Select the Edit > Preferences menu item
Select Internet from the Categories list box
Click the Internet Settings button
Select the Content tab on the Internet Properties dialog
Click the Certificates button
Highlight your digital ID and then click the Export button
Click the Next button on the Welcome panel of the Certificate Export Wizard
Select the Yes, export the private key radio button, and then click the Next button. If this radio button is disabled you can stop here and let me know that the private key is not exportable
Select the Include all certificates in the certification path if possible checkbox & the Export all extended properties checkbox and then click the Next button. Only select the top and bottom checkboxes, DO NOT delete the private key!
Create passwords for the file and then click the Next button. You will need this password to sign with so make sure it is something you can remember.
Pick a file name and location. Browse for a location you can remember as you will need to know where you put the file in order to use it to sign with. Click the Next button.
Click the Finish button
Click the OK button on the confirmation dialog
Click the Close button on the Certificates dialog
Click the OK button on the Internet Properties dialog
Step 2 - Add the file to Acrobat
Select Signatures from the Categories list box
Click the More button in the Identities & Trusted Certificates group box
Click the Add ID toolbar button
Click the Next button
Click the Browse button
Navigate to and select the file you exported above and then click the Open button
Enter the password you used above and then click the Next button
Click the Finish button
You will see two items in the list box with the same name. Highlight the one whose Storage Mechanism is "Digital ID File"
Click the Usage Options toolbar button and then select Use for Signing
Close the Digital ID and Trusted Certificate Settings
Click the OK button on the Preferences dialog
The next test is to see if you can sign a file. Please let me know if it works or not.
Thanks,
Steve

I am working with Acrobat 9 Extended Pro. How do you edit 3rd party pdf files?? Some do not allow.

I've been attempting to modify a 3rd party, original form purchase agreement -- so I may complete it with answers and save in my system for future submital or more editing. The form I'm attempting to complete with my laptop .. turns blue (converts to photo storage?) and makes it impossible for me to edit.
How do I edit under Acrobat 9 Extended Pro software -- Please advise ASAP.
Paul Johnson

You could add form fields or comment annotations. If you want to modify the text directly you may need to OCR the pdf and convert it to a text or Word document, edit the text, then make a new PDF.

Files encrypted and digital signed with cFolders

Dear all,
Currently I'm involved on a PPS project with cFolders. This project has legal requirements that consist in implementing encryption and digital signature in files which will be uploaded to cFolders. I've been searching on SAP Help, SDN and Service Marketplace about APIs to work with cFolders with encryption and digital signatures, but I didn't find related documents. It seems there is no documentation regarding such scenarios...
Anyone has experience in cFolders with files encrypted and digital signed?
Thanks in advance & regards,
Ricardo.

Hi Federico
If I understood your solution you are signing your documents in a Webservice provided from a CA. For that youu2019ve created an RFC dest type G over ssl (https) and used the class CL_HTTP_CLIENT. So your requirement is only to sign documents, right?
Well my scenario seems a little bit different as Iu2019ve to encrypt the file and also sign it. The signature is done on useru2019s laptop trough a smartcard (hardware device connected via USB that reads the chip the certificate assigned to our identity card) and cannot be signed from other entity than the user itself.
Did you explore the PGP alternative? cFolders supports this kind of files (*.pgp). The PGP (Pretty Good Privacy) is a popular program used to encrypt and decrypt files, e-mails, etc.
Today I installed a trial version of a PGP tool. I tested the encryption/signature with files on my desktop and it works fine. I tested a Public Key scenario where the owner publishes his PK in cFolders and the requester gets this PK in cFolders as well. The requester now can encrypt documents and upload them to cFolders with the public key provided by the owner; the owner itself has the private key to open the encrypted file (extension .pgp) after upload. But over the encrypted file the requester must sign it with his private key (another certificate) provided by a CA and here starts the second challenge...
In cFolders after the file upload the system should gets the requester digital signature and sends it to CA for validation, only after that we know if the requester is a trusted partner or not. To do this we are thinking to use a Webservice provided by the CA, however I don't know how to extract/get the signature in the file encrypted/signed from PGP and uploaded to cFolders.
Do you have any idea?
Thanks & regards,
Ricardo.

Serial number won't work with Acrobat 7.0 Pro

I'm trying to re-install my Acrobat 7.0 Pro on a new computer (Win 8.1) after a major crash. I successfully downloaded the new .exe file but installation won't accept the serial number listed for the download.

How do I digitally sign with reader XI when the fill and sign functions are grayed out?

I am using Adobe Reader XI. I am suppose to digitally sign a fillable .pdf document for online submission. However, the fill and sign functions are grayed out.
What are my options to put a signature in the signature box of the document?
Thank you in advance!

Pat Willener,
Thank you for replying.
Here is an image capture of the properties.
The document is part of a job application that is suppose to be digitally signed and submitted soon. I have thought about printing, signing, and redigitizing to submit, however, the cells are statically sized and do not expand to include all of the information when printed.
Any suggestions will be appreciated.

Help in putting movies into pdf with Acrobat 8.0 Pro for a free textbook

For the next version of my free 1500 page
physics text ( download at www.motionmountain.net )
I have big problems. I need to use Acrobat Distiller,
I have bought it for this reasons,
but I do not get embedded movies to work. Distiller
does not find the mpg files; the competing
freeware ps2pdf does.
This few line tex demo file works fine with ps2pdf
(using relative path to the mpg file)
www.motionmountain.net/testdir/filmtest.tex
www.motionmountain.net/testdir/filmtest.aux
www.motionmountain.net/testdir/filmtest.log
www.motionmountain.net/testdir/filmtest.dvi
www.motionmountain.net/testdir/filmtest.ps
www.motionmountain.net/testdir/filmtest.pdf
but this simple tex file for Acrobat Distiller,
with absolute paths, as Acrobat wants,
does not work:
www.motionmountain.net/testdir/filmtest2.tex
www.motionmountain.net/testdir/filmtest2.aux
www.motionmountain.net/testdir/filmtest2.out
www.motionmountain.net/testdir/filmtest2.dvi
www.motionmountain.net/testdir/filmtest2.ps
This is the Acrobat Distiller error text:
%%[ Error: undefinedfilename; OffendingCommand: file ]%%
Stack:

(/Users/christophschiller/Desktop/aFys-tex-6/Films/gyroprec.mpg)
{fstream1}
-mark-
%%[ Flushing: rest of job (to end-of-file) will be ignored ]%%
%%[ Warning: PostScript error. No PDF file produced. ] %%
(Found in www.motionmountain.net/testdir/filmtest2.log)
I use Mac OSX 10.4.11, Adobe Acrobat 8.1.2 Pro.
Mac OSX has no Unix "strace" command.
Somebody told me to start Distiller with the -F flag.
This might solve the problem. How is this done on MacOSX?
The OSX command structure I know of is
open -a Distiller.app filename.ps
This does not allow to add a -F flag for Distiller,
or am I wrong?
Any help is greatly appreciated !
Best regards
Christoph

Don't use Distiller to input the movie files, use Acrobat. Even if you
get the files into the pdf, the chances are they won't play properly in
Acrobat or Reader on the Mac.
Additionally, I don't think you can use mpg files. I think you are
restricted to .mov or Flash files on the Mac on Acrobat 8. I used to be
a .mov type of guy, but Flash player is available to more people. My
recommendation is to upgrade to Acrobat 9 for its new Flash abilities
which do not require either Flash or Quicktime. If you don't upgrade to
Acrobat 9, then go with Quicktime .mov files. Acrobat 8 and earlier will
only handle flash version 4 or earlier if my memory serves.
BTW, you avoid all these issues is you use the attachment tool, rather
than the movie tool, but then they cannot play within Acrobat, but will
launch a separate process. They you can use your mpgs.

Can't create a digital signature with acrobat 8

We have acrobat 8. My husband has a digital signature but when I try to electronically sign, his digital signature pops up and does not give me the option to create my own. How can I create my own digital signature on this software?

I don't have Acrobat 8, but in Acrobat 7 & 9 it's under "Advanced > Security Settings", which prings up a window where you can add a digital ID.

Adobe Reader 8 compatible with Acrobat Standard and Pro 7?

Our organization has Adobe Reader 7 deployed to all users. Some users also have Acrobat Standard 7 or Acrobat Pro 7. We want to upgrade all users to Adobe Reader 8 (or maybe 9) but do not want to upgrade Standard and Pro users yet.
I have not been able to find any information about compatibility issues with Reader 8 and older versions of Acrobat, but last time we did an upgrade in similar fashion we experienced issues. Any insight?

Thanks for the reply. I stumbled across something today after posting. I had already known that If the ARX user also had one of the other products (AAXS or AAXP), then they would get the dialog box. Here is what I just figured out: if the user uninstalled ARX and re-installed (still having both ARX and AAXS or AAXP in the end) then they no longer get the dialog box. It seems like perhaps its an issue the AAXP and AAXS are overwriting something in the registry.

File size increases dramatically after digital signature with Acrobat X

I signed a PDF file using Acrobat X.
File size of unsigned document: 200 k
File size of signed document: 3200 k (more than ten times bigger)
Any idea?
BR
Harald

Finally I found the solution.
The file size increase is a result of the embedded information used for long-term signature validation.
If you do not need this feature, you can turn it off:
Preferences > Security > Advanced Preferences > Creation tab
disable "Include Signature’s Revocation"

How to edit a PDF created with Acrobat XI Pro after signatures have been applied (like I can in 7, 8.0

I have a major issue that I need to resolve before we can purchase Acrobat XI Pro:
Currently, with Acrobat 8.1 Pro, after all signatories sign a document, we add an Effective Date (we add it after they sign since we don't know when the last signature will be acquired and we can't have an Effective Date that is before the date of the last signatory, otherwise, it would be effective before they signed it, which is not possible). I'm also allowed the latitude (as stated in our Documentation Control procedure) to make spelling corrections, hyperlink updates and minor formatting changes (by using the typewriter tool and also by replacing a page that is NOT the signed page if the change repaginates the document or involves modifying a hyperlink that has changed).
In all of the previous versions of Acrobat that we've used (7 Pro, 8 Pro and 8.1 Pro) , this has been easily possible and all changes would be listed under the Signatures tab, which is exactly what we want, which is traceability.
I'm using the trial version of Acrobat XI Pro now but am getting the message "This document is signed and can not be edited." If I bring the same PDF that was created from Word 2003 & 2013 using Acrobat XI Pro into 8.1 Pro, though, I CAN add the date, use the typewriter tool and replace non-signed pages, save it and exit without clearing or losing any signatures.
My question is this: How can I do this in Acrobat XI Pro, as XI Pro (in the Signature pane) also lists the changes made to the document when it was edited using 8.1 Pro? (It's OK that the changes made to the PDF then mark the signatures as "invalid", as the reason why they were invalidated is also listed in the Signature pane, e.g. "Form Field Added", which is usually the applied Effective Date.)
Thanks for any help!

Acrobat versions prior to 9 had a bug which allowed you to do what you did. In Acrobat 9 this bug was fixed. In order to do what you want you need to certify (apply special certification digital signature with your certificate -- it is "Certify (Visible/Invisible)" choice in the "Work with Certificates") your document first. In the process of certification you can specify which modification permissions you allow the users of your document to make after signing. Certification signature must be the first signature in the document.

I need to digital sign a document using Acrobat Reader. Is it possibile?

I am an IT Manager for a little city in northern italy.
I have almost 50 clients with smart cards enabled for what concerns digital signage.
I use flawlessy the software of the firm who provides the smart card. (infocamere.it).
This uses sha256 crypt, no problems about it.
The problem I have is:
The final file is a "p7m" envelope.
I would prefer to use a "pdf" envelope. One only file.
I tried to follow this video
http://tv.adobe.com/watch/acrobat-x/how-to-digitally-sign-a-document-with-adobe-reader/
Simply it doesn't work.
I have also a couple of Acrobat Standard.
I can "pdf-sign" with Acrobat Standard 9.
I am not able to do the same with reader 9 or X.
There is a way to do it?
Thank You.

You can sign a PDF using Adobe Reader 9 or X, but the document must be "Reader Extended" to enable this functionality, This can be done using ADEP\LiveCycle Reader Extensions (server product) or Acrobat Professional 9 (Advanced > Extend Features in Adobe Reader) or Acrobat X Professional (File > Save As > Reader extended PDF)
For some more info... http://www.adobe.com/eeurope/products/server/readerextensions/ or http://help.adobe.com/en_US/enterpriseplatform/10.0/Overview/WS92d06802c76abadb2c8525912dd cb9aad9-7ffa.html
