Adobe form Digital Signatures

Hello SDN,
I have to implement Digital signatures in my Webdynpro interactive forms. In sdn I found one example related to online Interactive form security but for offline I couldnt find.
In offline scenario, a user will send pdf form to customer or employee etc to fill the form and send it back.
1) Here how a receiver will know that he got the form, from an authorized person?
2) Once the form is filled and send it back, how receiver can validate whether the filled form came from an authorized person?
3) Also how exactly I can use digital signatures? what are the technical requirements for implementing digital signatures?
4) For implementing digital certificates do I need to have SSL configured for my j2ee?
Can some one guide me on this?
Appreciate your help.
With regards,
Ravi.D

Adobe Form Digital Signature using WDA

Hi,
I have implemented Interactive Adobe Form using WDA, with one Signature Field.
I need to set and verify the status of the Digital Signature.
1) Is it possible to sign the Adobe form without the user selecting the Digital Id, basically what is needed to implement automatic signatures (setting and verifying)?
2) Once the data is filled online, the form is to be distributed or downloaded. How to apply security parameters to Form in this case (like pass protected etc). From SAP documentation, I understand we need to use Adobe Policy Server. Can we install this server on the Java stack of SAP WAS. Are there any other alternatives to implement such features?
Thanks & Regards,
Chitrali Shah

I realize there is quite a bit of crossover between the two topics, but becuase you want to know about digital signature and specifically offline security; this question would probably be better asked in the Adobe Interactive Forms forum:
SAP Interactive Forms by Adobe
However I'm not going to lock the thread, as the WDA forum you will find many Forms experts as well and might find a solution. I just think you might have better luck in the other forum. This is perhas a rare case where double posting would be appropriate as long as you go back and update both threads with any solutions.
It sounds like you may have already found it, but about all I can offer on the subject is the link to the latest version of the online help on the subject:

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.

Xfa Form, Digital Signatures, file attachments and Reader 9

Hi,
In reader 8 and previous, when i wanted to have a form that could be signed, passed to the next persons, added attachement signed, repeat, while maintaining the signatures valid, i could.
Since we updated to reader 9.12 all previously signed documents appear with invalid signatures and if i try to attach a file, the add button just isn't there.
If i follow he following steps:
Server side:
- Create PDF from xdp + xml (using forms).
- Assign Form Fillin, Digital Signatures and File Attachment (using Reader Extentions)
Client side:
- Populate the Form data
- Attach files
- Certifiy
- Sign (multiple Signatures)
It works fine, but it isn't the workflow i had in previous versions.
The workflow i have here is:
Server side:
- Create PDF from xdp + xml (using forms).
- Assign Form Fillin, Digital Signatures and File Attachment (using Reader Extentions)
Client side:
- Populate the Form data
- Attach files
- add Signature (only locks a collections of form fields)
- Repeat until everyone has attached their files and signed.
The problem is that this worked fine in versions before 9 (all digital signatures here validated with the yellow exclamation mark indicating new content), but in 9 and up what i get, after validating the signatures in reader, is a information indicating that the signatures are invalid because the document is either corrupt or has been changed.
Is this a bug or has this been changed from version 8 to version 9?
I've read the changelist of reader 9 and it talks nothing about this situation or Digital Rights other than form fillin, annotations and digital signtatures (the ones we can choose in the certification wizard of Acrobat Pro).
Any idea if its possible to implement the second scenario in reader 9, or even if its possible? Is there a guide on the practices Adobe garaties will allow to validate signatures in the following years? Even if it means usings PDFA.
Thanks in advance.

One last try.
You help would really be welcome in finding out the root cause of the difference in behaviour between reader 8 and 9 in this matter (bug or change).
I have no idea what documentation to read (since i've read the launch documentation and change list documentation) about reader 9, i've contacted Adobe 3 days ago (and the answer is silence, like usuall) and have no clear thought about what to say (without taking a huge risk by giving a uninformed answer) about this issue.
Thanks.

Dynamic xfa form - digital signature becomes invalid

Greetings forum,
I have question regarding dynamic xfa forms and hope, that you can help me.
I filled a pdf form based on a dynamic xfa form (with extended rights for Reader user) using iText. When the content of the PDF is changed, the digital signature becomes unvalid, so that the rights are no longer vaild.
Therefore Adobe Reader (9.0) does not save the PDF. I get the following error message:
"This document contained certain rights to enable special features in Adobe Reader. The document has been changed since it was created and these rights are no longer valid. Please contact the author for the original version of this document."
I tried the following workaround with itext:
PdfStamper stamper = new PdfStamper(reader, new FileOutputStream(RESULT), '\0', true);
(http://1t3xt.info/tutorials/faq.php?branch=faq.itext&node=enabled_form),
but I doesn't seem to work.
As a result, the rights are valid but the content of the PDF wasn't changed.
Is there any workaround for that or does it only work static xfa forms/acroforms?
Many thanks for you support!
Irina2000

Sounds like you tried to fill in a form using Acrobat without the form feature use. Actually iText from what I can see is not using Acrobat, but a third party product. To fill in the form, you simply use the hand tool to move over a form field where the tool will change to an Ibeam or similar pointer tool. Select the field and type in the data. That should not make any changes to the PDF in the sense that has been stated. I have no clue where iText comes into the picture.

Forms, digital signatures, cross platform issues

I am trying to implement pdf forms in an educational environment to utilize digital signatures and reduce paper. The form data does not need to go anywhere. It just stays in the form at this point. Some people on campus have Windows machines, others have Macs. All the Windows machines have Acrobat Pro installed and not Reader. The Mac people are more likely to have Reader. There have been problems with emailing these forms between platforms. Does anyone have any ideas about how to solve this? My IT department will not support Reader on Windows machines, so the forms have to work in Acrobat and Reader! How should the orginal document I put online be saved to work in both programs and platforms? What direction should I give the users about how to save the forms they fill out and sign? I've looked all over for this kind of info, but can't seem to find it. Any and all help is greatly appreciated. FYI, I am not an IT person. Thanks!!!

For Mac users, it will be important that they don't use the Preview application to work with the forms. Preview is the default Mac PDF viewer out of the box, and it corrupts PDF forms when it saves them, so it really needs to be avoided.
In order for Reader to save a filled-in form and apply digital signatures, the forms need to be Reader-enabled, which can be done with Acrobat Pro. Acrobat Standard can Reader-enable documents too, but it doesn't apply the digital signature usage right.
The problem with this is if you will be getting the forms returned to you, you can only use data from no more than 500 instances for the form, including hardcopies. This is an Acrobat License Agreement restriction. If they won't be returned, there won't be a problem. Also, the Acrobat users don't need to use a Reader-enabled version, so you can collect all the forms you want from them.
Email will be most reliable if the user manually attaches the file to an email, as opposed to setting up a button on the forms to submit to an email address. You'll find many threads here discussing the emailing difficulties with forms that are set up this way. The problems can be minimized with user education, as the manual process is available in either case. A submit button provides convenience, unless it doesn't work, and it won't for some users.

Hi friend,
Its not like that the Adobe created using SFP is non interactive.
We can create interactive forms using SFP transaction using java code.
I think it will be the problem with ADS just check with your basis people i think they will configure you the settings which works fine.
To check whether the settings are perfect you can try executing the standard programs FP_TEST_00 and
FP_PDF_TEST_00. If it works fine then some other problem exists else check with your basis team.
Just check this and revert me if you have any issues. I will help you

Interactive Form - digital signature and fields locked

Hi everyone,
Lets say we have 2 input fields in the Interactive Form.
In addition, we have a digital signature field that locks.
How can I specify which fields I want to lock ?
Thanks
Regards.

Hi David,
Lets say you have a digital signature field. What you could do is on the click event of the Signature field, you could Lock the 2 input fields.
Say Text1 & Text2 (Names of the Inputfields respectively) by using the following Commands.
Text1.access = "readOnly";
Text2.access = "readOnly";
Note : Before adding the code set the Language to "Java Script".

Adobe Reader Digital Signature Plugin

Hello All,
We had developed a adobe plugin for digital signature through smart card. The plugin works fine for Adobe Professional. I would like to know the procedure how to make it work for Adobe Reader. I found a URL http://www.adobe.com/devnet/reader/ikla.html which says to buy a license. I'm confused over DRM and non-DRM agreement.
To make it clear, our company shall be distributing the smart card and the plugin in the enterprise market for digital signatures that need to work with both Adobe Professional and Adobe Reader. Our customers shall be probably using Adobe reader.
Can any one let me know the procedure to make reader plugin?

Hi Gatis,
Check out the Security and Digital Signature Admin Guide athttp://learn.adobe.com/wiki/download/attachments/52658564/acrobat_reader_security_9x.pdf?v ersion=1
http://learn.adobe.com/wiki/download/attachments/52658564/acrobat_reader_security_9x.pdf?v ersion=1
Once you get the file open look at section 5.3.4.4
The folder path has to exist, but Acrobat will create the file if it's missing. For example, if you want to save the file to C:\LogFile\digSigLog.txt the folder LogFile would have to exist on the C drive, but the log file itself will get created if it's not there already.
When you type in the file path and name in the Edit Binary Value dialog in regedit, make sure you null terminate the string by typing a zero at the end of the hex data on the left side of the dialog. It will look like a dot on the right side, but it's not really a dot (a dot is 2E in hex).

Digital Signatures with Adobe Reader

So i created an adobe form with acrobat 9 and sent it out for all to digitally sign. about half are getting an error when they try to sign it. "The credential selected for signature is invalid"
We are a government agency and use Common Access Cards (CAC) certificates to digitally sign with.
i was hoping someone out there could either point me to a good recource for adobe and digital signatures or to a possible fix.
now we have narrowed it down to the problem being with the specific machine. the user can digitally sign the document on another machine, but not on thier own machine. Also, no one else can sign the doc on thier machine either.
Thanks in advance!

issue still exists. ive been searching for some info on how adobe handles digital signatures, like what folders are created on the machine. im thinking maybe i can clear out the app data for acrobat or something. im at a loss at the moment.

How to enable digital signature for browser enabled infopath form?

Dear all,
I have designed infopath form and published it into the document library. I want to provide signature option on the browser enabled infopath form.
I have created it using secion and digital signature control.
but I am getting this message.
When i click on Yes . I get following screen.
And it just hang here. I have enabled the active x control feature for IE.
Please tell me where i should install this component and how it can be done?
I have access only to the sharepoint site.
Thanks

Hi,
According to your post, my understanding is that you want to enable digital signature for browser enabled infopath form.
To be able to sign this form, you need to activate two Windows Internet Explorer add-ons. Click the Information Bar in the dialog box, and then click Run ActiveX control to activate each add-on.
Then you need to active the following add-on.
In my environment, after I click the Next button, it open the picture as below.
Once I click the link to add the add-on as above, everthing works well.
For more information, you can refer to:

Digital Signature in ABAP

Hi,
I read some document related to digital signature. Everywhere it is mentioned that thru adobe only digital signature concept is possible.
But in our project we have a requirement, we are supposed to bring the digital signature thru abap itself. that means using module pool or smartforms or sapscripts we have to bring the digital signature.
Is it possible? Pls suggest.

Problem with digital signatures in Acrobat 8

Is it true that the ability to directly create a digital signature field is available in Acrobat 7 & 9 but not in 8?
I have Acrobat Standard 8.0.0 and want to create blank signature fields before I certify a document, but can't find a way to do this directly. I can add a signature then delete it to create a blank field, but this is a very slow way of doing it.
I have read Forum articles saying choose Tools > Forms > Digital Signature Tool to create a blank field, but I have no Forms item in my Tools menu. Am I missing something, or do I need to upgrade to Acrobat 9 (or downgrade to 7!)?

Hi Brian,
It's not that version 8 per se cannot add a signature field, it's that you cannot create or edit form fields in the Standard version. If you had Acrobat 8 Professional, or you buy Acrobat 9 Pro, then you would have the capability to add and edit form fields (a signature fields is just a special purpose form field).

Support for using Digital Signatures

I work in the legal department in a large company. We are considering using Adobe's Digital Signature for our annual reports and financial documents. However, I am unable to find how to get support on using such a feature. Is using this feature pretty simple with Acrobat Pro v. 9? I walked through the step-by-step features to initially set it up, but are there additional things I need to do to make sure the signature is completely secure? Do I need to purchase additional features or add-ons? Is it possible to get someone to come to our company and provide a training on this feature?

Using Acrobat Pro to digitally sign PDF documents is a very simple feature to use from an end user's perspective. No extra plugins are required to have Acrobat generate a digital signature. What you do need however is a digital certificate for each user, the certificate is used to create a user's digital signature. Acrobat does not provide the ability to manage certificates, for this you require a Public Key Infrastructure (PKI) from a company such as VeriSign or Entrust. Here are Adobe's security partners:
http://www.adobe.com/security/partners/index.html
Are you looking to have end users sign documents? Based on the types of documents you described, you may want to look into "Certifying" documents using Adobe's Certified Document Services. You can get some more information here:

How do I remove the digital signature option on Adobe Acrobat 7.x? I don't want it, but it pops up every time I need to sign a form, and I cannot find a way to remove

I created a digital signature to sign forms using Adobe Acrobat 7.x. I really don't want or need this feature, but do not know how to remove it or keep it from popping up every time I need to sign a form. Can anyone help? I'm not that technically savvy, so please explain in layman's terms. Thanks!

It's not clear to me what you're trying to accomplish. If you get rid of your digital ID you will still be prompted to create/add one when you need to sign a form, which you say you still need to do? Do you really just want to e-sign (hand-drawn signature, or stamp) instead of digitally sign? Do the forms you're using have digital signature fields?
