Acrobat X Signature

I am woking with Acrobat Pro 10.1.7 on mac OS 10.6.8.
I made a new ink signature by scanning my signture and importing it in to Acrobat > Preferences > Security > New. That worked and I can see that signature under Preferences. When I try to sign a document, however, I cannot find that new signature when I go to Tools Panel > Sign and Certify > Sign Document. Why not?
Marc

Tools Panel > Sign and Certify > Sign Document is for PKI-based (certificate) signatures, not for image-based signatures. What you did, you specified appearance for your PKI-based signatures. What you want to do is to use Comments Panel->Add stamp->Show Stamps Pallete. Select "Sign Here" and "Import" to import the image of your signature. Then use Comments Panel->Add stamp->Sign Here to apply your signature as a stamp. Keep in mind that this signature is not a PKI-based signature that has support behind it. It is just an image that you add to PDF.

Adobe Acrobat 9 Signatures

I have set up a signature in Adobe Acrobat 9 and when you draw the box for placing your signature everything behind it is "whited" out. Is there a way to change the settings so you can see where you are placing your signature? I have to sign a lot of documents (i.e. contracts) where I have limited place to place it and I need to not cover up the wording where I placing my signature. Is there any way to do this? Any offered suggestions to solving my problem??
Thanks

Hi Amy,
I'm a bit surprised you are seeing this because it is not the default behavior. Normally, when you add a signature field to the document both the fill and border are turned off. But, since it is looks like fill is enabled what you could do is:
Select the View > Toolbars > Advanced Editing menu item
Click on the Select Object tool (it's the arrow that points to the upper left on the Advanced Editing toolbar)
Right mouse click on the signature field that is obscuring the underlying text or image
Select Properties from the pop-up menu
Select the Appearance tab on the Digital Signature Properties dialog
Click the button next to Fill Color and then select No Color from the pop-up pallet
Click the Close button on the Digital Signature Properties dialog
That should get you fixed up. I hope this helps,
Steve

Adobe Acrobat - Digital Signatures Security

Hi,
The business I am working for is making a push for online fill in forms for simplicity and less paperwork. At the moment they are using word docs with fill in sections that are terrible to deal with and still require you to print them out to sign it.
I have developed a PDF fill in form using Adobe LiveCycle that uses digital signatures. My only worry is how the digital signatures are created. It seems it is fairly easy to create a digital signature for someone else and use it without it being authenticated.
I have done some reading around and it seems to suggest that you are able to intergrate windows user accounts with adobe security somehow, but I am unable to find how to do this. I also don't have access to any of the windows security certificates so I will need to pass on information to the external IT company that manages it for them to do.
So, more specific question: How do I intergrate Adobe Acrobat signatures/security with windows user accounts so that only a specific list of users are able to sign forms.
Or if there is a better way of doing this let me know.
Thanks

Hi,
You don't need to do anything. If the user has loaded their digital ID into the Windows Certificate Store (or the Mac Keychain) then Acrobat (and when I say Acrobat I mean both Acrobat & Reader) will pick up the digital ID and make it available at signing time in the Sign Document dialog, "Sign as" drop-down menu.

Adobe Acrobat Reader Signature Field not Accessible

I created a form using Adobe Acrobat Pro XI. It has a signature field. The security settings are off, and according to Pro, all abilities including adding a signature are allowed. When I open the document in Reader XI, I cannot sign it. The Sign tab is available, but all options in that tab are grayed out. I cannot double click on the field or click the signature icon. What settings am I missing?

Here are three documents that i down loaded, there are others

Certifying and Locking file Invalidates Certification and Signatures in Acrobat 9.0.0

I am running Adobe Acrobat Professional 9.0.0. After creating a PDF document from within Microsoft Word, and it opens in Adobe Acrobat Professional, I performed the following steps:
Select Forms => Add or Edit Forms.
Select the digital signature tool and create three forms.
Select Close Form Editing.
Right click the first form and select Certify with Visible Signature.
Set Permitted Actions After Signing to Form Fill in and digital signatures.
Select Sign.
Save the document, replacing the original file.
Click on the second field, to sign it, and select sign.
Save the document, replacing the original file.
Click on the third field, to sign it.
Select Lock Document After Signing, and select sign.
Save the document, replacing the original file.
I then find that the certification and the first signature are invalid. Only the last field to be signed is valid. Why is the previous signature and certification invalid? This only appears to occur if I both certify and lock the document when signing the last field. If I view the document in Adobe Reader 9, the result is the same. However, if I view the document in Adobe Reader 8 the certification and all the signatures are valid, as expected.
Any assistance much appreciated.

David,

Thanks for the responses Geo & Atin,
Geo,
Maybe I'm misunderstanding what you're saying, but http://www.adobe.com/devnet/reader/articles/reader_compatibility/readercomp_digitalsignat ures.pdf seems to indicate otherwise. Specifically:
"In Acrobat 9, when additional signatures are applied to a document, the earlier signatures continue to have the Valid status, subject to the certificate validation rules that have been part of Acrobat's signature processing for a number of releases.
In Acrobat 8, all signature appearances except the last one would have changed their status to "Valid with subsequent changes" (green check with a yellow warning triangle) if their certificate was still valid."
So I read this that in neither version should the signature be "invalidated" by simply applying another signature, but in version 8 it showed the triangle warning, and in version 9 nothing would change. Indeed nothing does change in version 9 and it works EXACTLY as described above providing I don't both certify AND lock the document. I still don't understand why just the extra locking step violates the "certificate validation rules".
Atin,
I carried out the steps that you described, and it works thank you. I notice that the lock option is not present when I sign the last field now, but presumably this is because by the time the last field in signed, with the settings you describe the document is effectively fully locked anyhow?
Now my problem is, is there any way of setting up templates of the signature fields laid out in the correct position, with the settings that you describe that I can use repeatably on many documents? I wish to use this function to electronically sign technical drawings which are drawn in a CAD package using a template based title block with 'drawn by', 'checked' and 'approved' fields etc. Each drawing may also have many sheets, each with the same fields in the title block. My concern is that to manually place digital signature fields in these 3 spaces in every title block after creating the PDF's, and then apply the settings you describe before certifying (at 'drawn by') and distributing for sign off at 'checked' and 'approved' is going to be a very time consuming and inefficient process. Am I missing something?
Regards & thanks again,
David.

Place signature & DigSigHFT (Acrobat Plug-in [C++])

Hello All
I have problems with operation "Place signature" in Adobe Acrobat Prof
I get sigField==null in callback function DSNewSigDataWithParams after user place signature inside document with help of "Place signature" button.
I see only DigSigBBox in parameters with size of new signature.
How I can get position of new signature from Acrobat?

Example of code:
ACCB1 DSSaveType ACCB2 DSNewSigDataWithParams(DigSigNewSigDataParams sigParams, void **pSigData)
if (CosObjEqual(sigParams->sigField, CosNewNull()))
//I need to create new signature field here, but I don't know positon of new signature in document
//I only know size of new signature (I can get it from sigParams->bb)
1. Is it bug in Acrobat?
2. Maybe can I use other callback functions to get position of new signature?
3. Maybe must Acrobat create signature by self and put it to DSNewSigDataWithParams?

When filling a Digital Signature field from a mobile app, signature does not show Reader or Acrobat

Scenario :
1. Receiving a pdf form with digital siganture field.
2. Signing form using various pdf apps. " PDF EXPERT for iPad/iPhone"
3. After signing and emailing the document, opening in reader or Acrobat, the signature does not display but the field is gone, as if it was signed.
* Is reader /acrobat requiring a validation that it is not receiving to show the signature?
Did verify that the signature shows in Chrome, using chromes default pdf viewer.

Acrobat Upgrade and Signature Appearances

We're about to upgrade our Acrobat users from X to XI. We've got a number of users who have created custom signature appearances they use when signing documents. In the past when we upgraded Acrobat these signature appearances were lost. Is there a way to move existing signature appearances to the new version when upgrading so that they don't need to be recreated by users?

Search the system for a file called "appearances.acrodata". It should be in the Acrobat user folder, in the Security subfolder. The specific location depends on the version of Acrobat/Reader and OS. For example, on Windows XP:
C:\Documents and Settings\user\Application Data\Adobe\Acrobat\11.0\Security\appearances.acrodata

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

Signing with digital id in Acrobat Reader DC

We have been using Acrobat Digital Signatures for long time. I have just installed Reader DC and I am trying to find out how it can be done in this new version. In the Edit / Preferences I am able to create digital ID and setup it's appearance but I cannot find how to sign the pdf document with this signature. Is it still possible ? How it should be done ??

Restricting application of Digital Signatures

Hello,
I am trying to determine what options are available natively in Acrobat for restricting the type of certificate that is used for applying a digital signature. As far as I can tell, Acrobat, by default, seems to allow the use of any certificate which has the "Digital Signature" extension. This has the potential to create large problems in a regulated environment.
In my organization, our users receive multiple certificates for different applications. For instance, a user may have a certificate for VPN access, one for SMIME email and finally, one that is specifically for applying eSignatures. There is a more robust vetting process for obtaining an eSignature certificate, and it also prompts for a passphrase each time the private key is accessed. Each type of certificate comes from a separate CA.
We've configured the Trusted Identities in each user's Acrobat by deploying an addressbook file to them. We've only defined our eSignature CA as a trusted CA in Acrobat (along with some other universally trusted authorities). The result is that when a signature that has been applied using any other CA, Acrobat will not verify the signature. This is good, but it is not good enough since the dynamic images that come with Acrobat digital signatures do not appear on printed or flattened documents.
Basically, I'm trying to determine whether there is a way to configure Acrobat (natively, out-of-the-box) such that it will only allow application of digital signatures using certificates that are issued from a CA that is defined as a Trusted Identity.
Has anyone encountered this before?

Hi Mike,
The short answer is yes, you can restrict signing to a certain type of certificate. However, you do need to be able to edit each PDF file that needs to be signed.
To expand a bit, the process is know as applying a Seed Value. There are two different types of PDF files and they each have a different method of applying Seed Values. If the PDF is an XML template that was created using LiveCycle Designer, then you can apply the Seed Value to the signature field using the Designer software. On the other hand, if the PDF file is the more ubiquitous AcroForm (e.g. you converted a Word Doc to PDF), then you have to use JavaScript to apply the Seed Value.
Before I get into the specifies of applying a Seed Value, first here is what a Seed Value can do. Among other things, you can use Seed Value to restrict signing to:
a specific user's digital ID
digital IDs issued by a specific CA
a digital ID that has a specific key usage value (it sounds like this is what you are looking for)
If you need to use JavaScript you are doing to want to review the published JavaScript guide. You can find the guide online at http://livedocs.adobe.com/acrobat_sdk/9.1/Acrobat9_1_HTMLHelp/wwhelp/wwhimpl/js/html/wwhel p.htm?href=JS_API_AcroJSPreface.87.1.html#1515775&accessible=true and search search for Seed Value. More specifically, you are looking for the JavaScript call signatureSetSeedValue and the section (about half way down the page) CertificateSpecifier Object. At the bottom of the page are examples of how to set the certspec object.
If you are using LiveCycle Designer you need to display the Object pallet. Select the Window > Object menu item to get the Object pallet to display. Then, select the signature field that you want to apply the Seed Value to, select the Signature tab in the Object pallet, and then click the Settings button. This is the dialog you use to apply the Seed Value.
Good luck and let me know if you need more help,
Steve

How can I integrate a Topaz signature pad to place the signature on the document? It is a certificate signature on the pad that isn't going onto the document.

Adobe doesn't support a signature pad for Adobe Acrobat but the Topaz pad sees and registers the signature on the computer but not on the document? Suggestions would be greatly appreciated.

Hi Mary,
Did you not get software from Topaz along with the signature pad? You should have gotten a file called signplus.exe (or gemsignplus) that installs the software that integrates the Topaz signature pad with Acrobat. Then you need to go to the Signature Creation preference and select Topaz as the default signing method. You can also select Always ask and then you would be prompted to select either Topaz or the traditional Acrobat digital signature when you click on a signature field.
How to get to the signature preference depends on the version of Acrobat you are using. If you let me know I'll give you the exact steps.

Scan.api error after scanning and then clicking no for no more pages. Acrobat x pro then closes.

I never had a problem scanning and saving the file before. But now I receive an error after I finish scanning, then hit "no" for no more pages to be scanned. Error message is as follows: Adobe acrobat error signature: AppName: acrobat.exe AppVer: 10.1.10.18 ModName: scan.api ModVer: 10.1.10.18 Offset: 00033117.
Then the program closes.
This is really driving me crazy because I haven't done anything different to my computer or the scanning process. Please help.

Hi Charlene Luong,
Could you please let me know if you are on Windows or MAC.
Also, restart your computer and check for your system updates.
Hope to get your response.
