I livecycle process verifies the validity of digital signatures

Hello, I have to create a process that I livecycle verify the validity of digital signatures in PDF format. can you help me?

hello thanks for the reply, I tried the process and works in part, the only problem in the variable verificationResult
process output tells me <identityStatus> UNKNOWN </ identityStatus> though I imported the certificate in to livecycle
how can I fix this?

Validating a digital signature in an xml

Hi,
Im working on validating a digital signature from an xml file . Im using the below code to get the value of signature node from the xml file.
NodeList nl = doc.getElementsByTagNameNS(XMLSignature.XMLNS, "Signature");
I'm getting it as nodelist object . When i try to get the length of the signature element it says 0 and hence it throws me an exception .
I have to pass this nodeliest object to validate the xml file. Im attaching the xml file as well as the progarm to validate the xml file . Can somebody help me on this.

// Instantiate the document to be validated
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
dbf.setNamespaceAware(true);
Document doc = db.parse(file);Your problem is that you've instantiated the DocumentBuilder before you've made the factory namespace aware. As a result, does not know against which namespace it is parsing the XML file.
Change the lines of code to have the factory be namespace-aware before you instantiate the DocumentBuilder and then parse the class. You'll get past your "node not found" error to receive a number of other errors which you need to correct.
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
dbf.setNamespaceAware(true);
Document doc = dbf.newDocumentBuilder().parse(file);As a practice when generating an XML document, you should try to validate it inside an IDE like Netbeans/Eclipse before trying to do anything with the document to ensure you've not only got a well-formed XML document, but also one that is "schema-conformant. Your XML signature is not (the Object element cannot come before the KeyInfo element, and the SignatureProperty element is missing the required Target attribute); as a result your Signature element will fail to pass validation even if your code is correct. A cursory review of the XML Signature specs and its XSD is always helpful: [http://www.w3.org/TR/xmldsig-core/].
Finally, please use the {code} tag for source-code to make it readable. Thanks.

What is the use of Digital Signature in export release build for AIR applications

hi Freinds..
what is the use of digital signature identity when we release build?

Well obviously it is an Ant build.
It looks to just compile/build a web application into a war so you can deploy it where you want to.
You don't need to edit it every time you are making a new page. It should work for any generic struts web application laid out in the fashion it expects.

Validating a Digital Signature or ID

I have created a Digital ID and signature in Adobe Acrobate. When I sign a docuement and sent it to others, they are using Adobe Reader X (version 10.0.1) to open the docuement. They get the following error message at the top of the document. I belive they need to validate the signature in order to get rid of this error. But I am not sure how to vallidate the signature.Can anyone help me do this?
Thank you!

The issue here is not the validation of the signature but rather trust in the signature. Much like you need to verify a handwritten signature to be sure it is coming from the person you expect, Acrobat by default also recommends you check the signature as well.
For more information on this, please refer to this series of blog entries, which will give you the details on trust in signatures:
http://blogs.adobe.com/security/2011/03/trust-us-trust-in-electronic-signatures-revisited. html
Thanks.

Validation before Digital Signature

Hello everybody,
I created a form in Lifecycle ES working like a charm.
Now i have added a JavaScript for validating the entries in the Form.
My idea is to launch the validation before the user enters the signature. When the signature is added the validation must have been passed successfully.
I have begun with adding an event_enter JS to activate the validation.
The Problem is that the signature dialogue box opens anyway. How can I get rid of this dialog box?
Thank you for your kind help
Best regards
Ch. Du Champs

Please post in the LiveCycle Designer ES forum.

Validation of digital signature

Hello All,
Can anyone please tell me how can i validate the digital signature field before submitting it through submit button.
Regards,
Menaka.H.B

Hi Chintan,
it's me again
I implemented everything like explained in the documents! Especially the guide "How to Secure the Access to the Adobe Document Services" was very useful for me!
But unfortunately the signature in my PDF document will not be validated.
I have this scenario:
1. Start BPM workflow
2. Generate PDF and send to user
3. User fill out form, sign it and send it back to the forms mail server
4. Readout user input and map to BPM content
At the moment it does not matter if I sign with valid or non valid, or no sign the PDF. It works anyway!
May you help!
Regards

Prompting for SAVE as the document with Digital signatures in 8 or above

When i am doing digital signature on Adobe PDF 8 and above , it is prompting to SAVE AS the document.I am accessing the PDF documents from my document management application and signing on that.So Save as wouldnot work for our case.It should save on the default existing location.How to solve this issue?

Thank you very much for your responses. The final post on the forum at the link you provided explains the issue. It appears to be some sort of conflict with the Windows Explorer document previewer that is causing this. Whenever I am previewing the document I am working with in the Explorer, I cannot save changes. As soon as I preview a different document, the changes can be saved without any problems. In the interest of providing further information so that a more permanent solution can be found, I am running Windows 7 and have had this problem with Acrobat 9 and X. Files are being saved locally. Unfortunately, I do not have the savvy to tell you what kind of server.

What is the legal validity of digital signature in adobe reader?

Good afternoon.
Sign In option of Adobe Reader, I can pick up a manual signature by a person. My question is.
Is this sign legally valid signature? Can replace a signature on paper?
many Thanks

You need to apply a specific right to the file first in Acrobat.

Hello, I'm looking for software which allows me to create purchase orders in front of the customers with digital signature

Also, it would be great if I could make my purchase order by indicating my product and adjusting the quantity.
Once, order is made that my quantity in stock is also adjusted. Hope you'll know what I mean ?

And also the possibility to have my orders converted in packing slips and invoices... :-)

The Application's Digital Signature has an error

I get this error when running ColdFusion MX 6.1
Name: coldfusion.applets.CFTreeApplet

Certficate Details show certificate is goog through June 9,

How can I avoid this error message when running this java
applet on our web server?
If I pick “Run”, it runs, but the next day when I
run it again, this message will popup again.
I can check the “Always trust content from this
publisher” and the problem goes away on that workstation.
There will be a lot of people using this applet and I
don’t want them to deal with this.

Digital Signature Validation process goes into unending state

Hi all
I am working Adobe Digital Signatures in Web Dynpro Java applications. I have been using [this|https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/com.sap.km.cm.docs/media/streamingmedia/developer-areas/user-interface-technology/interactive-forms/securing%20online%20interactive%20forms%20by%20adobe%20(Session%208)/index.html?slide=] webinar to follow steps to configure SSL and validation of Digital Signatures.
After doing all necessary configurations, I am able to run my web dynpro applications containing interactive forms in secure mode.
But when I sign with digital signature and try to validate the form, the application keeps on processing and shows no result.
I tried debugging my application but control does not reach my button action code. I am clueless.
I would be thankful to receive any hints or pointers from you.
Thanks in advance.

Digital signature does not validate with the given key

We are switching our single-signon provider from openssl to Weblogic's SAML. I am trying to create a test application that will send mock SAML assertions to our test Weblogic SAML server before we begin integration with the client that will send real SAML assertions.
I have configured a Weblogic 10.3.5 instance to be a SAML Service Provider as well as created an application that creates test SAML assertions to post to the SAML server. I'm currently using a self-signed certificate to sign the SAML assertion. I've imported the self-signed cert into both the DemoIdentiy.jks and cacerts on the Weblogic SAML server.
The Weblogic SAML server is giving the following error when trying to validate the signature of the assertion:
<SAML2Assert: Start verify assertion signature>
<SAML2Assert: The assertion is signed.>
<SAML2Assert: Digital signature does not validate with the given key
org.opensaml.xml.validation.ValidationException: Digital signature does not validate with the given key
at org.opensaml.xml.signature.SignatureValidator.validate(SignatureValidator.java:68)
at com.bea.security.saml2.util.SAML2Utils.verifySamlObjectSignature(SAML2Utils.java:229)
at com.bea.security.saml2.providers.SAML2Assert.verifySignature(SAML2Assert.java:285)
>
I get this error when the SAML assertion includes both the cert and the public key, just the cert, just the public key or neither.
I'm pretty sure I've configured the SAML instance correctly since I followed the steps provided by another group who got this working with a different client. The only difference is they are using a real signed certificate (Verisign i believe) instead of a self signed cert.
I'm looking for any help to track down which step in the process I've missed or implemented incorrectly.
Thanks!

So I found my own answer to the issue. The error was being caused by an the following xml in the assertion:
<ds:Reference URI="">
The value of URI attribute must have a '#' followed by the same value of the ID attribute in the parent 'Assertion' element (in our case a random string):
<saml:Assertion xmlns:saml="urn:oasis:names:tc:SAML:2.0:assertion" ID="a5k42vnhsywezqzyufq15c4bb9xuzeozrmbppj38xe" IssueInstant="2012-03-12T14:33:25.986Z" Version="2.0">
<saml:Issuer>ISSUER_NAME</saml:Issuer>
<ds:Signature xmlns:ds="http://www.w3.org/2000/09/xmldsig#">
<ds:SignedInfo>
<ds:CanonicalizationMethod Algorithm="http://www.w3.org/2001/10/xml-exc-c14n#"/>
<ds:SignatureMethod Algorithm="http://www.w3.org/2000/09/xmldsig#rsa-sha1"/>
*<ds:Reference URI="#a5k42vnhsywezqzyufq15c4bb9xuzeozrmbppj38xe">*
How this is related to the digital signature is beyond me, though I admit I'm very new to saml and digital signing. However I spent a great deal of time investigating my certs and how I was creating the signature, which it seems is unrelated to the actual issue. I also wasn't able to find any docs specifying that this attribute was required, though I might have just missed it.

Acrobat 9,10 failing to validate digital signature while Acrobat 8 validating it.

I am facing an issue while validating a digital signature. I applied a certified signature with “Annotation, form fill-in, and digital signatures” but
when I apply Redaction “find and permanently remove” on a digitally signed document, Adobe Acrobat 9 and 10 complains that signature is Invalid But Adobe 8 is validating it. I have analyzed that Adobe Acrobat applying Redaction in append mode and original content of signature remains unchanged after Redaction.
Can someone let me know what should be the actual behavior?
Why Adobe Acrobat 9 and 10 failing to verify the signature even Adobe Acrobat keep enable Redaction which means it is allow to apply in a certified signed document with “Annotation, form fill-in, and digital signatures” option.
Prompt responses are greatly appreciated!!

When you sign, you should see where you can select the signature appearance name from a dropdown in the dialog.

How do I prevent the use of a digital signature?

I realize this flies in the face of some core security issues built into PDFs, but here we go...
We have a customer for whom we are creating fillable PDF forms. Due to the nature of the documents, they require handwritten signatures on printed hard copy. Since the ability to digitally sign any PDF is enabled by default, and especially since Acrobat Reader X apparently prompts the user to use a digital signature, our customer is concerned that some end-users (most of whom will be non-tech-savvy) will be confused by the digital signature concept and would prefer to prevent the use of digital signatures at all. I have played with the security settings in Acrobat Pro, but they are not granular enough to allow filling in a form without also allowing a digital signature. Any way to prevent signing?
Thanks,
Mike

@George Johnson:
I tried to edit and save the form from within Acrobat Standard X, but it didn't seem to make any difference.
@brogers_1:
I am not familiar with EchoSign, but since the end-users are not part of my organization, nor my customer's, I won't have access to their registry settings.
I don't want DigSigs at all.
There is no signature field in the document--unless it is somehow hidden.
When a user either left- or right-clicks any form field (in Reader X at least), a window pops up titled "Form Can Be Filled and Signed Electronically" with a note to click "Sign" etc.:
