Embedding Documents and Adding Digital Signatures

I have the following two questions regarding Adobe Acrobat XI pdf fillable forms that I can't find in the manual:
Embed supporting documentation and/or copy and paste information within the form
Allow digital signatures to be saved within the electronic version of the form
I would appreciate any feedback available.
Thanks!

How to Create a PDF Document and apply Digital Signature in C# using the Adobe SDK?

Hi Everybody!
I have to do two distinct tasks here:
1) How can I create a PDF document using the Adobe SDK in my .NET Applications(C# - 2.0)?
I just need a basic sample to create a document with a simple text, for example. I did not find any useful information in the adobe documentation. I have the Acrobat Professional 8.0 in my computer, but it's very dificult to work whith de Acrobat.dll and .NET with a poor documentaion.
2)How can I apply digital signature in a existent pdf document?
I need to sign documents using the SDK, just a basic sample in c# would be helpful to start!
Anybody could help?
Thank in advance!

Leonard Rosenthol or anybody that can help, sorry to insist.
I will explain better my problem:
I have an ASP.NET WebPAge (C# - 2.0). In this page, the user make a request. The request should generate a PDF document with the informations of the request and with a field to add a digital signature. The document created will be send to a approver that will confirm the approval applying his digital signature (I need to do too, a webpage where the approver open the page, choose the pdf document, and sign, just selecting his own certificate and clicking in the button SIGN... but this is another problem).
That's the reason that I have to create a PDF document. If I create a WORD or HTML document, and then convert to PDF, how can I add a field to digital signature in this pdf document?
Is there any solution using Acrobat SDK?
Thank you very much!

Annotation field locked and subsequent digital signatures

Hi all,
i'm testing my PAdES digital signature library in Obj-C and i encountered this kind of PDF file
http://dl.dropbox.com/u/3995257/PDF/Locked.pdf
Acrobat Reader tells that the document is locked by a signature (Signature2). As far as i know locked means that the file can't be modified but is is impossible to append a digital signature too?
I tried to sign the document with my lib and as expected the second signature invalidates the first.
http://dl.dropbox.com/u/3995257/PDF/Sign_Locked.pdf
But... i tried to sign for the third time the previous file. I would expect that the first (locked) signature would be invalid but the second and the third would be not.
http://dl.dropbox.com/u/3995257/PDF/Sign_Sign_Locked.pdf
Despite my expectations, only the last signature is avalid according to Acrobat Reader.
Does the first locked signatures invalidates the subsequents? Or more simply i can't sign a Document locked PDF?
Thanks

Yes, because the first is a lock – anything you do after the fact will invalidate.

Connect smart card reader over usb and access digital signature certificate

Hi,
I got digital signature certificate stored in a smart card.I places smart card into card reader and plugged usb port of server.
I can see card reader in windows environment.My problem is to connect card reader and access digital signature certificate using java code.
I thinh it needs javax.smartcardio but i did not find necessary jar file for jdk 1.5.xx.
1- Where can i download jar fiel for javax.smartcardio for jdk 1.5.xx
2- Is there a blog or forum thread to help me to use smart card over usb?
Thanks.

One of the beauty of Java is that when the Java VM does not let you do something (here: accessing a Smart Card), there is no way that a purely Java solution will add this functionality.
Hence, what you ask simply can not be done in pure Java (1.)5. Some machine-specific non-java code is required. And you did not specify your target.
Unless a jar file could contain machine-specific code (I don't know if this is the case, and I never made one such jar file), there seems to be no way a jar file could help.

Adding Digital Signature Fields to Multiple Pages in a Document

Hello,
I have a batch processing java script which will place digital signature fields in a drawing.
Sometimes the drawing could have multiple pages and the script needs to place the digital signature fields onto each page.
The problem with the script I have is that the digital signature fields are only appearing on the first page.
Can anyone please provide assistance with modifying my script so that the digital signature fields appear on every page?
// Drawing signature field rev 0
var numpages = this.numPages;
for (var i=0; i < numpages; i++) {
var a = this.addField("Checked", "signature", i, [1783, 174, 1724, 198]);
var b = this.addField("Designed", "signature", i, [1783, 149.5, 1724, 173.5]);
var c = this.addField("Design App", "signature", i, [1783, 125, 1724, 149]);
var d = this.addField("Proj App", "signature", i, [1783, 101, 1724, 125]);
Thanks very much.

Just index the field names:
var numpages = this.numPages;
for (var i=0; i < numpages; i++) {
var a = this.addField("Checked"+i, "signature", i, [1783, 174, 1724, 198]);
var b = this.addField("Designed"+i, "signature", i, [1783, 149.5, 1724, 173.5]);
var c = this.addField("Design App"+i, "signature", i, [1783, 125, 1724, 149]);
var d = this.addField("Proj App"+i, "signature", i, [1783, 101, 1724, 125]);
Tho there's no point in signing each page in the same document, tho I also see engineering folk do this. They just love signing every data sheet.
And the result will not be good. Each signature will cause a problem/alert for the previous signatures.
Care to indicate your engineering company?

Checking to see if a document has a digital signature

Hello,
I have created a stand alone static PDF document using the Designer 7.0.
I have some code that checks the document to ensure the proper data fields have been filled out before the user can sign the form. After signing the form the, the user is supposed to click a submit button where 2 things happen, first the data is sent for processing (do not the the digital signature info here) and second a copy of the PDF is save for archiving purposes (with digital signature).
What I need to know is how do I verify the digital signature field is not null or empty?
If I check its raw value, before and after are the same (null or empty even thought I can see that the form has been signed by looking at the screen). If I used the signatureInfo functions available in professional, I get a security violation error. The form is filled out using Adobe Reader and the forms have digital signature right added via the Reader Extensions v6.0.
Any help is greatly appreciated.
Thanks
Ben

Hi Ben, First advice is upgrade to designer 7.1. There are major improvements in the stability of designer. 7.0 kept crashing on me constantly.
I created a little function which should help you out.
function isSigned(sigField){
var oState = event.target.getField(sigField).signatureInfo().status;
/* if (oState == -1)
//app.alert("Not a signturefield");
else if (oState == 0)
//app.alert("Signature is Blank");
else if (oState == 1)
//app.alert("Unknown Status");
else if (oState == 2)
//app.alert("Signature is invalid");
else if (oState == 3)
//app.alert("Sig of Document is valid, identity of signer could not be verified");
else if (oState == 4)
//app.alert("Sig of Document is valid, identity of signer is valid");
else
//app.alert("Value was " + oState); */
return oState;
You need to pass this function the fully qualified SOM so if the signature field is in form.subform.page1.sigField you would call it like this isSigned("form[0].subform[0].page1[0].sigField[0]").
Good luck.

Acrobat 9 and Validating Digital Signatures

I'd heard that Acrobat 9 had found a way to eliminate the problem of sending your certificate to everyone who needs to validate your signature on a form, but I haven't been able to prove that. I'm testing 9 and so far the only difference I see is that instead of seeing an icon next to the signature stating that it can't be validated, it now states it in a bar across the top of the document. Has anyone else found something different?
Thanks!
Anita

For a signature to be considered valid, there must be a "trust" relationship between the validator and the signer. So if I sign a document and claim to be be "Bill Clinton", the signature doesn't show as valid unless you've established that I really signed the document using Bill Clinton's credentials. Public key cryptography provides this assurance by signing using a private key and publishing a public key that can be used to verify that the real private key was used. But you have to have that public key, and that is what is distributed and "trusted" within Acrobat or Reader.
In Acrobat 8, there are basically 2 ways to get that trust relationship: 1) Exchanging certificates with people you trust or 2) purchasing a certificate from an Adobe partner that sells pre-vetted and trusted certificates (where you have to do some work to prove you are who you say you are). These certificates have a trust relationship pre-built into Acrobat so you don't have to set up trust.
In Acrobat 9 there are 2 new mechanisms for establishing trust, but they facilitate, but not eliminate the need to establish trust.
First, you can create a security settings file which includes trust relationships and distribute it to your group either in an ad-hoc way (email, etc.) or by posting on a server and having Acrobat or Reader automatically load the settings. This makes it easier to set up signature workflows in a small group or enterprise environment.
Second, there is a new way for establishing large scale trust for digital identities issued by large organizations such as government agencies or countries where these will also have trust automatically managed by Acrobat and Reader.
The new features are described in http://www.adobe.com/devnet/acrobat/pdfs/sharing_security_settings_90.pdf

Acrobat 9 Standard and the Digital Signature usage right

Acrobat 9 Standard is apparently able to apply certain usage rights to a document. I am trying to confirm whether or not the digital signature usage right is included. The
Acrobat 9 product comparison seems to indicate it is not, but the online help implies that it is.
Can someone with Acrobat 9 Standard confirm this for me by testing a document that you've enabled for use with Reader by attempting to sign a digital signature field with Reader?

In the office area, the Pro version might be good to have for the forms and other features. For the general library, Reader is probably adequate. Actually allowing PDF creation on public machines can be an issue. In a small libary system, Acrobat might be reasonable where you do not have to deal with a large, diverse population. However, for basic PDF creation, only Std is needed. Having both AA8 and AA9 on the same machine can lead to problems. However, if you remove one, you will likely have to repair the other.
The problem with older versions is that they may not properly read some of the newer PDFs that might be downloaded. For the latter, you could install the latest version of Reader, but you need to be aware that you may have to deal with issues of right clicking (windows) on a file and selecting which application to open a PDF with. For forms and some editing, the Pro version would be good to have. You also have PDF Optimize and PreFlight with the Pro version that generally are not including in the Std version.
To help compatibility with the files you create, you can select Start>Printers>Adobe PDF preferences (right click on printer). In the settings tab>Default settings> select at least Std or better Press or Print and then push edit. Under the general tab select the compatibility and set it to AA8 so that every thing is compatibile with the oldest version of Acrobat you have.
If you have more than one computer in the office, you might consider having AA8 on one and AA9 on the other. Do check and be sure you have licenses for whatever you have and that someone has not come in and installed a pirated version. Also be sure you keep the original CDs and licenses (or if they were downloaded, burn the downloaded version to a CD as an archive and write the SN on the label).
Now that I have confused you, are there more questions?

Adding digital signature field with LC Designer vs. LC Digital Signatures

Hi All,
When digital signature field named "SignatureField1" is added to PDF document using LC Designer it appears as "form1[0].#subform[0].SignatureField1[0]" in Adobe Reader signatures tree.
Same field added by LC Digital Signatures service appears as "SignatureField1" in the same tree.
Why? What is the difference between those objects?
LC Digital signatures ES2
Adobe Reader 9.3.0
Thanks, Yan

Yan
First off, there is no difference between the two signature field objects.
I'll do my best to explain why there is a difference in how the signature objects are named in the Signature pane of Reader\Acrobat. When you add the signature field using LC Designer, the object is defined in the underlying XML (XFA) that defines the form. The (SOM expression) you see in Reader (via the signature pane) matches the structure of the form.
When you add a signature field to a form using LiveCycle Digital Signatures ES2, you are appending a signature field "on top" of a PDF form (the underlying XML has been rendered into PDF). The signature field is not defined in the XML, therefore Reader\Acrobat do not display the same naming syntax.
Does this help?
Thanks
Steve

Adding Digital Signatures to PDFs

Hi all,
Sorry if I am posting this question in the wrong location, but hopefully someone who sees this message will still be able to answer or point me in the right direction. I did perform a search and could not find a definitive answer.
There are documents in my company that will be circulated for approval and we would like to apply digital signatures to indicate that certain personnel have reviewed these documents. I have Acrobat 3D version 8.1.5 and I know I have the capability with that version to add digital signatures to a PDF. My question is: Is that true of all versions of Acrobat? If not, can anyone tell me the most recent version of Acrobat that has this capability. I won't necessarily be the one creating the PDFs; thus, the question.

Released document without complete digital signature

Hi All!
I'm working with digital signatures in the DMS system and I have set the release indicator so that two signatures are needed to release a DIR. The problem is that the DIR gets the green release status after saving the first signature. I get the feeling that this is a bug in the system but I have tested it in two systems and it works the same way in both systems (one of them is a ECC6.0 EHP5 system and should have all the relevant updates). The whole idea with digital signatures at the release status is in my head that the DIR does not get released before all stakeholders have signed the DIR. Am I wrong or have I done anything wrong in the config?
Best regards,
Kristoffer P

Hi Kristoffer,
Any specific logic as to why you intend to use two digital signatures to release a DIR?
Because,in your case,you can fulfill your requirement by using a single digital signature for a DIR.Herein,since there are two bodies involved for releasing a DIR, you may define the 'Signature Sequence' and the 'Release Sequence' in digital signature customization.This will ensure that that document is released/green indicator set only after body A and body B both have digitally signed the DIR in the sequence specified.Does this help?

Adding Digital Signature to XML strings

Hello All ,
i'm looking for functionality to add digital signature, encoding & decording to XML Payment fiels with encryption as well.i have searched on SDN but i havn't found any solution.
waiting for some useful thoughts on it.
i have see Programs SSF* as well , but it requires PSE settings which i dont want to use .Is there any others ways to do it ?
Thanks & Regards
V.

Yes, you need a certificate to sign.
You need a special one for yourself, one that also contains your private key.
Your message is signed with your private key (actually encrypted with it), after that anyone can see you signed it using your public key.
Encryption works the other way round: You encrypt it with openly available public key of the recipient, but only he will be able to decrypt it with his private key.
BTW you can create your own certificate, using Keychain Access>Certificate Assistant. The disadvantage is that they are not automatically accepted as valid, since they are not listed in the X509Anchors keychain. You have (and whoever you deal with) manually import your (public) certificate into the Keychain X509Anchors as well. Double clicking the certificate gives you the option to do so.

Acrobat/Reader and PADES (Digital Signatures)

I've read the document that James King of Adobe published and made the configurations to make Acrobat PADES compliant. However when I sign a document and inspect the generated CMS package inside the PDF, the signing-certificate value in Signed-Attributes is not present. So I'm assuming that the signature is still not PADES-BES compliant. Is there anything I can do to make Acrobat put a PADES-BES signature?
Also, I for verification, I made a test. I've externally signed a PDF with a CMS packet that has signing-certificate signed attribute. The signature has been validated in Acrobat. After that, I've intentionally put a random value as signing-certificate value. When I opened that PDF, it still validated fine in Acrobat. Therefore I understand that Acrobat doesn't do full PADES-BES validation. Is this right? Is there a configuration that can make Acrobat make a full PADES validation?
I'm using 9.1.3 version of Acrobat under Windows.
Thanks in advance

Hi Stewen,
Thank you for your answer.
I've took the value of Contents dictionary value and inspected it with an ASN.1 viewer. You're right, the signing certificate is on the PKCS7 (CMS) package. However, PaDES doesn't suffice with that. It requires a signing-certificate value in the signed attributes inside SignerInfo sequence in CMS. Also, the subfilter value should say ETSI.CAdES.detached as mandated in ETSI TS 102 708-3 V.1.1.1 page 8.
e) The signature dictionary shall contain a value of ETSI.CAdES.detached for the key SubFilter.
Since we are mandated by EU guidelines our customers require ETSI compatibility.
Thanks for you help

Creating an interactive CV: mouse over / roll over pop ups, embedded documents and videos

Hi everyone,
I am pretty new to Adobe Acrobat Pro and new to this forum (1st post here!). Greetings from Spain... and apologies for grammar mistakes and misleading explanations (in advance). I have been checking this forum and googling quite a bit, but I do not get to many conclusions (maybe I sleep few due to our baby!).
I want to create an interactive CV with the following characteristics:
1) CV in 1 page in a PDF document (no problem here!)
2) Hyperlinks in the text which open embedded files (pdf of others) hidden to the viewer but which are in the pdf document. Possible? (I want the recruiter to receive just one file). Even better if they could be open in another window (doubt it).
How could it be done? I try add documents and they are attached at the end, so the original pdf gets to have more pages, all viewable.
3) Furthermore, mouse over / roll over pop ups which show you a preview of the file you may open clicking the hyperlink, for a quick view of the content.
I think that this may be done, but using other programs, like InDesign. I just try to add a document, but it's sort of a link to a document in my computer. I may add pdf, pps files.
4) Even more, would it be possible to embed a video which would open in a new window? If not, I tried to add a link to youtube and there was a warning as "this program tries to open a window, if you trust the owner... " (similar safety message) and the very last thing I want the recruiter to have to decide whether to decide to watch it or not.
I know its a questions in its very first stages, but the big point is to know if/what it is possible to do, so that I search in the right direction.
If you have any idea or advice (even if not related to PDF pro, of course), just please let me know.
Thanks a lot in advance. I hope this thread may help others.
Cheers,
tebanseeker

Hi Dave,
Thanks a lot for the input.
(3) Right, I could not find either a way using just Acrobat Pro (I'm using XI). Sad thing that you confirm it... But it looks like you may do it using other programs on the PDF, but I don't know to use them. You may take a look at this:
https://www.youtube.com/watch?v=HEyJuT8SSME (popup rollovers using Illustrator)
https://www.youtube.com/watch?v=YOVRMVdZbVE (popup rollovers using InDesign)
(4) I think that embedding would make the file to big, so I may opt for the hyperlink to youtube option, even if I deeply dislike that message, although youtube is a reliable source for the viewer.
Any other input is very welcome. I am pretty illiterate in the field!
Have a nice weekend,
tebanseeker
