Can no longer digitally sign documents

We have been using Active Directory based cetificates to digitally sign adobe pdfs for years. All of sudden after some recent updates we can no longer sign documents. When you click on a signature field and click "sign" on the pop up box, nothing happens (no error, no nothing) and pop up box stays there. I have checked and the certifcate is still valid and trusted. Everything seems to be valid. This is happening with clients that have Adobe x and Adobe 9 Reader. I tried to go back in to Adobe Professional 9.5 and certify the document but the same thing happens there! I simply can not sign anything. I have confirmed that this is an issue on other computers in our domain as well. Without an error or something else to go on, I am at a loss on how to troubleshoot. Our certificate authority is a 2008 R2 box and the clients are Windows 7.

Support information has a value as long as the product is supported. I believe Adobe ended Acrobat 9 support about a year ago. Even if there is a problem in the product (and the support information usually indicates a problem in the product) it will not be fixed since the support for this product has ended. Upgrade to Acrobat XI, it is so much better for digital signing than 9.

HELP - Can no longer digitally sign documents on Adobe Acrobat Pro ver 9 ?

Was able to for the last 8 - 10 months then 2 weeks ago it stopped (intermittently). Now when I go to sign I get through the process and can see my signature on the docuemnt but then I get this error "creation of this signature could not be completed" unknown error - support information CSigDict-1938" and cannot save it.
I deleted my signature and re did it but that has not helped. I am running Windows 7
thanks

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.

Stringing a number of Digitally signed documents together

Hi, I am currently running a project to convert my companies hard copy documentation packs to fully electronic, digitally signed documents.
The final document will be a string of several digitally signed documents combined together in one final document for presentation to our customers. I am currently having diffuculty retaining the original digital signature of the documents when they are combined.
I am using Acrobat Pro XI and have tried Certifying and just digitally signing but the original signatures appear to be deleted in the final document.
The real world application will be the initial company signing their docs for authentication and email it to their customer, this company will add docs to this first file and sign it then forward this on to their customer, etc until it reaches me when the completed document file will be locked.
Can anyone point me in the right direction?

Thanks, I finally worked it out. However, it's not an ideal format for how I originally visualised the outcome. From what I have read on the Adobe site and the discussion threads it doesn't appear that you can combine several digitally signed documents together to make a single document pack.
I had hoped that there was some way to have, say, 3 documents digitally signed by different people then merge these together into a single document but still retaining their individual signature details. This final document could then be certified by myself as the final recipient.
This final document pack could then be added to the final customers portfolio with many other documents.
The only way i can see to do this at the moment is to "sign" the documents with an annotation (ie. a JPG or PDF stamp), or use the built in stamps in COMMENTS, combine these into a single document and then digitally sign / certify this completed pack.
Has any one encountered this situation before and managed to solve it?
I understand that, because a change has been made to the original document this nullifies the orignal digital signature. I could live with this as long as I could retain the signatories details on that document.

Installed both 10.1.4 and 11.0.08 updates this week and now I can't use the Digital "Sign" document feature. It's been completely removed. Need it back. Please help..

I installed both 10.1.4 and 11.0.08 updates this week and now I can't use the Digital "Sign" document feature. It's been completely removed. Need it back. Please help.. Can't sign or add text to any pdf document. Even when security properties allow it.

I would remove Reader and repair or reinstall Acrobat.
Having different major versions can cause some users issues. Reader is not necessary if one has Acrobat installed. Even though Adobe has improved the capability of having both Reader and Acrobat with the same major version level there are still user configurations that have problems with this setup.

How can I apply page watermarks to digitally signed documents

When printing a digitally signed PDF I need to apply a watermark across each page that states the hardcopy is an uncontrolled version of the document. I understand how to allow updates to specific form fields after the document has been signed, but cannot find a way to allow the application, removal, or modification of page level watermarks after the document has been signed.

I do not want to invalidate the digital signature when applying a watermark.
The use case is when a user prints a hardcopy of a digitally signed SOP, a watermark needs to be placed on the page that states the hardcopy is an un-controlled document, the print date, and an expiration date.
I realize that any change to a digitally signed document is normally considered to be an operation that invalidates the signatures. However, it is possible to specify fields that may be changed AFTER the signatures are applied without invalidating the signature. I am looking for the same capablity with watermarks.

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.

Password protecting digitally signed documents in Adobe Acrobat X Pro

I am looking for the combination of steps to get my digitally signed documents to be password protected for secure distribution. My documents contain new "user password" information and a number of "areas" which require digital signatures to be added.
Any input as to how one would construct a document with :
one to three --> digitally signed signatures fields in one document
Password "opening" protection for the document containing the fields; both signatures and sensitive data fields
suggestions on how to make the document open to accepting more signatures without it demanding the creation of a newly saved document after being digitally signed by one signature
I have worked at this a couple of different ways but am having problems finding the right combination/sequence of steps to make it all come together.
Please assist.....
Thanks....

......meaning.......
I can't do locking of the printing or editing of the sheet after i have encrypted and signed it. Trying to do so, wipes out out signatures. Yes, it is a great fullproof to have people be unable to change something someone has signed but if there is an ammendment, can't the creator reserve that right and in an automated sense notify the signers of the rights of the author ?
Maybe I am looking for too much but, it would be great to know if that is the reality of the whole event.
Thanks,
Robert

Why is the validity of my digitally signed document displayed as unknown?

Why is the validity of my digitally signed document displayed as unknown?
Adobe X version 10 1.4
What exactly do I have to do under Preferences-Windows Integration?

Hi amyemia,
The signer's identity is unknown because it has not been included in the list of trusted identities and none or its parent certificates are trusted identities" indicates your recipients needs to add something to their copy of Acrobat/Reader. What the recipient of the document is missing is a certificate and only you can provide him with a copy of the certificate you created to sign the PDF. After you send him or make available a copy of the certificate, then he will need to import that certificate into his copy of Acrobat
Please refer : http://helpx.adobe.com/acrobat/kb/validity-digital-signature-displayed-unknown.html
If you want your PDF signature to be valid on your / co-worker's computer, you need to supply them with your Public certificate. To do this you need to export it out as an .fdf file, if in Acrobat X, choose Edit – Protection – Security Settings, select your ID that you used to sign the PDF with and choose Export, you can then either save it to disk, or directly email your certificate, get your co-worker to double click it in Adobe Reader and follow the prompt, when you see Set Contact Trust, select it and check Use Certificate as Trusted Root. Then click OK. Now open the PDF and it should now be valid.

Printing Digitally Signed Documents

I need to be able to print digitally signed documents and would like to know if there is a way to restrict the ability to print the documents that have invalidated digital signatures. Essentially, I want to be able to email a document for remote printing and only allow the document to be printed if the digital signature is valid. It would be of additional value to me if there was a way to place a "voided" watermark across the document if the digital signature was invalid. Any thoughts or suggestions would be greatly appreciated.

Thank you.
Is there a tutorial online that would show me how I can do this?
Process Description:
1) Create pdf document from AutoCAD. I generally am required to create one pdf file per drawing sheet so I may have 100 pdf files that I am working with.
2) Assign an RM policy to each file (Could this be a batch process since I may have 100 files I am working with) that would revoke the file if the digital signature was invalid.

Without the iPad connected, open up iTunes on your computer. Go to iTunes/Preferences/Devices and delete the backups that you're absolutely certain do not have the documents. Refer to figure below.
iTunes, select the iPad and then select the Summary tab. Follow directions for Restore and be sure to say "NO" to creating a backup. (You don't want to create a new backup that does not have the docs.) You will then be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finishes, you will be asked if you wish the contents of the backup to be copied to the iPad. This time, say "yes."
Repeat all of the above as required until you get the docs.

winmail.dat files usually mean the email has been sent in rich text format - you could either the person who sent it to send it in a different format e.g. plain text or HTML, or there are a few apps in the store that support it (search for winmail.date in the store).

How do I undo an update to pages 2.1 on an iPad 2? I can no longer open a document previously saved, even when I try to open it in the iCloud and on my Mac.

How do I undo an update to pages 2.1 on an iPad 2? I can no longer open a document previously saved, even when I try to open it in the iCloud and on my Mac.

With IOS Pages v2.0 and v2.1, Apple introduced a new document format that is incompatible with prior Pages versions on IOS or OS X Pages ’09. Opening older documents with these recent versions of Pages will permanently prevent the document from opening in earlier versions of Pages on IOS or OS X.
Nice of Apple to warn people.
There is no undo of an iTunes application update, short of forcing iTunes to restore IOS v6 back on that iPad 2. Even if you did that, you won't find the IOS Pages v1.7.2 in the iTunes store now.
IOS Pages v2+ will allow you to export content in Word .docx format. You do this by first tapping the box with an up-arrow in it (next to the left-most +). A menu will slide up — choose Send a Copy. Select a document icon. Pick Mail, and then Word. Your Pages v2.1 document will now be converted to Word .docx, and attached to an email body. Fill in the to address and send.

I can no longer print any document in PDF format. Not sure why

I can no longer print any document in PDF format. Not sure why? When I try to print, the document saves to my hard drive as a PDF and will not allow me to print? Never had this issue before. Any thoughts?

Print to file is in the main print dialog (on Acrobat 9.x) as opposed to under Advanced

Before the reset quit Pages like this:
Double click the Home button to show the screen with running and recently used apps. Each app icon will have a sample page above it. Flick up on the page (not the app icon) and the page will fly away and the app icon will disappear. This quits that app.
