Validate Digital Signature - Check CRL
Hi all,
(1) Is it possible for LiveCycle Document Security to validate the digital signature and check CRL, if there is NO CRL Distribution Point in the certificate itself?
(2) Can I hardcode the CRL's URL in the LiveCycle Document Security's configuration file?
Thanks.
Sanney
Sanney,
I don't know about the CRL URL question, but if I understood correctly what you are trying to achieve, then:
If you already have CRLs or certificate files at your disposal, you can store them in disk. You can then select "advanced" option when installing. This will allow you to point at the directories containing the credentials , so these can be included as an integral part of the overall server deployment.
If later on you want to update the credentials, you can run Configuration Manager. You must then rededploy the updated server components to the application server.
I'm currently writing this out of memory, but the documentation is very clear about this procedure.

Temporarily disable Digital Signature Checks to Install MS SQL Server 2008 with no Internet Access
I am attempting to install a licensed copy of MS SQL Server 2008 in a Private Enclave that does NOT have Internet access on a Win2008 R2 SP1 server (that is VM - thus I can't reboot and press F8 to select "Disable Driver Signature Enforcement"
). The installation fails with an error of the vc_red.cab file being found either corrupt or a bad digital signature. The file is good, but the signature has an expiration of 2011. I understand that a DOTNET SDK v1.1 program called setreg.exe
will enable disabling the digital signature check, but I am not permitted to use that program.
I might be permitted to use the "Signtool.exe" utility, but it is not clear what command sequences are necessary to disable and then re-enable the Digital Signature checks.
I saw a thread that recommended using the command:
bcdedit.exe /set nointegritychecks ON
However, the comments indicated that this might not have worked.
Are there Registry settings I can use with regedit to make the necessary changes to be able to install the application? I anticipate running into this problem with other software when I do not have Internet connectivity. I already tried
downloading the Microsoft CRL files; updated the lists on the Server; and rebooted. This did not solve my problem.Hi,
As far as I know, it is not recommended to disable digital signature check.
Since we are not familair with installing MS SQL server, please also refer to SQL forums below to see if experts there have more insights regarding the matter.

Cannot validate digital signature - Reader 11.0.10 on Windows 8.1
We cannot validate digital signatures in Adobe Reader 11.0.10 on a Windows 8.1 PC, but the same signatures/documents can be validated in the same version of Reader on Windows 7 Pro. Is there a known issue with signature validation in Reader XI and Windows 8/8.1?
Hi CTMutual_CMHC,
This might not have happened for Windows 8.
Could you please try validating signatures in some different PDF and check.
You can also refer the following link for the same:
https://helpx.adobe.com/acrobat/using/validating-digital-signatures.html#validate_a_digita l_signature
If the issue persists, then try installing the latest version of Reader from here:
Adobe Acrobat Reader DC Install for all versions
Let me know how it goes.

Hi,
I have a large number of PDF files signed with a digital signature.
I would like to extract from each file the certificate and call OpenSSL to check the validity of this certificate.
Does anybody knows a way to extract the certificate without opening the file?
Does anyone used the app 'Document Security Livecycle' for this purpose?
Thanks for your inputs!The Document Security product has APIs to validate signatures on PDFs.

I have a C# windows application that uses the AxAcroPdf control to display PDF documents that contain digital signatures. The signatures show as "not yet verified" when the documents are loaded into the activex control. The signatures show as validated (with green checkmarks) when the same documents are opened in Adobe Reader. What am I missing in my application? Do I need to set some property on the activex control to validate the signature while loading the documents?

When you say adjustment how did you pass the adjustment ? what transaction code was used? normally to post a payment without printing check you can use F-53 and that should not print any checks.

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.

Validating Digital Signatures when they come back to you.
Ok so I've sent out some forms & have received them back
Now it seems that I must "Validate" every signature?
Is that correct?
What does that mean exactly? That I went throught the form & verified all of the information was correct?
Is there anything specific I should be looking for or changing the settings to when I'm trying to validate digital signatures?First, you need to view the signature to see if it was issued by a trusted source (like Verisign or Microsoft). If a trusted source was used, then it is valid.
More info on digital signatures can be found at: http://office.microsoft.com/en-us/help/HA012308751033.aspx -

Software Update - digital signature incorrect
I have several update packages that were consistently reporting the error:
*The update "xxxxxxx" can't be saved.*
The digital signature for this package is incorrect.
The updates are:
iLife Support 9.0.3
Java for Mac OS X 10.5 Update 4 1.0
Safari 4.0
Several other updates (eg. recent iTunes and QuickTime) downloaded and installed OK.
I tried all of the following to no avail:
Repair disk permissions
Reinstall 10.5.7 combo package manually
Delete Software Update preferences & cache files
Multiple restarts
Finally I tried running Software Update under a fresh admin account and they downloaded OK. (Different issue that the Java Update later said it couldn't install).
So seemingly this is related to something in my usual admin account. Does anybody know what other preference files I should look to delete, or any other hidden setting that is affecting the digital signature checking?I tried all of the following to no avail:
Repair disk permissions
Guess Carolyn didn't notice this.
This was happening fairly frequently about a month ago when 10.5.7 came out. The Apple servers were overloaded apparently and some incomplete downloads occurred so some type of checksum prevented running the update. Waiting and downloading later seemed to be the best solution.
http://discussions.apple.com/thread.jspa?messageID=9456350�
So seemingly this is related to something in my usual admin account. Does anybody know what other preference files I should look to delete, or any other hidden setting that is affecting the digital signature checking?
Perhaps by the time you did all the troubleshooting steps, if you tried it from the original admin account it would have downloaded correctly. -
Digital signature on Form 16 - PDFManipulation Module error
We are trying to implement digital signature on form 16 and have followed instructions in note # 1168740. One thing that remains is the installation of 'Trusted Anchors'. The procedure for installation of trusted anchors is to copy the Trusted Anchor file (<filename>.cer) to the /usr/sap/<SAPSID>/SYS/global/AdobeDocumentServices/
TrustManagerService/trust/certificates directory.
We have installed ReaderRights and ServerSignature. All we have is a '.PFX' file that contains the digital signature of the signing authority. This is issued by the authorized Certifying Authority (CA).
Q. What is '.CER' file and where do we get this file from.
When testing the server side signature test program - FP_PDF_TEST_07, we get the following error:
ERROR CODE : 201,501
ERROR MESSAGE :
Processing exception during a "Sign" operation.#Request start time: Fri May 07 14:46:36 IST 2010#com.adobe.ads.exception.FailedCreationExcepti
ADS: com.adobe.ads.exception.FailedCreationException: Failed to create a new instance of PDFManipulation Module, please make sure PDFManipulat
Any tips on how to proceed further will be highly appreciated.

Fault in adobe digital signature revocation checking schema
Hello,
I have found some fault in adobe digital signature revocation checking schema. If OCSP response signing certificate contains CRL distribution point (in my case CDP (CRL) and AIA (OCSP)), online OCSP check executes, but after getting all chain certificate OCSP responses, validating signature against CRL (it’s looks from Local cache). It means you never get OCSP validation data in Adobe Acrobat or Reader signature revocation tab.
Adobe Revocation Checking Quick Key schema is following:
Check Embedded revocation responses
Check local CRL cache C:\Documents and Settings\<user>\Application Data\Adobe\Acrobat\9.0\Security\CRLCache
Check Online OCSP response
Check Online CRL response
LAB environment:
Certificate chain E-ME SSI (RCA) (Root Certificate) -> E-ME PSI (PCA) (Policy Certificate) -> E-ME IS (CA1) (Issuer certificate) -> User certificate (Document signing certificate)
Sign PDF document (Ocsp-CHECK.pdf) using Adobe Acrobat 9 with User certificate (Don’t add revocation information in signature)
Test steps:
Sign PDF document using Adobe Acrobat 9 with User certificate (Don’t add revocation information in signature)
Clear Local CRL cache under C:\Documents and Settings\<user>\Application Data\Adobe\Acrobat\9.0\Security\CRLCache
Open signed file using Adobe Acrobat 9 or Reader 9
Verify signature. Verification process finishes successfully. Under signature properties in certificate windows and user certificate revocation tab you can see that revocation information data comes from CRL. The same for all chain certificates. But if we look in chain and user certificate its holds AIA record for OCSP service.
After a couple of tests I tried to disable access for Acrobat to local CRL cache folder (Everyone – Full control deny).
After disabling access to local CRL cache folder - verify the same signed PDF file. Opening document you can see OCSP checking progress and verification process finishes successfully. Under signature properties in certificate windows and user certificate revocation tab you can see that revocation information data comes from OCSP. The same for all chain certificates.
Resolution:
Its looks when Adobe starts online OCSP checking and receives OCSP response they start parsing OCSP response signer certificate and check OCSP signer certificates revocation information. In this process CRL for OCSP signer certificate is downloaded and placed in Local CRL cache C:\Documents and Settings\<user>\Application Data\Adobe\Acrobat\9.0\Security\CRLCache
Somehow when Adobe gets all chain certificate OCSP responses and have verified also all OCSP signer certificates, online OCSP check is no more continued and revocation information are taken from Local CRL cache.
Can you please help me to clear how to deal with this problem, to make sure that procedure works correctly?

Hello,
My Problem:
By client-certificate-based authentication the first step is to prove "Does user�s public key validate user�s digital signature?". How can I prove this on the ServerSide manually, resp. I want to verify it with java classes on the server side additional to web-server. Actually the Web-Server verify this through the SSL-Connection, I'm conscious of this, but how can I additionally verify this step with java classes.
Thanks a lotYou would have to code it all again from the client side: obtain the certificate and private key from the keystore, send the cert, sign it, send the signature, and have the server receive the certificate and check the signature, all as part of your application protocol.
Instead of all this duplication I have no doubt that you should just point your firm at RFC 2246 in which the Certificate and CertificateVerify messages are mandated, or at the pages of Rescoria's book that I pointed you to before. The transport already meets the requirement and there is zero value in re-implementing it. Indeed there is a negative value: (a) there is a development time and execution time cost which they should consider, especially the development cost, and (b) if you get it wrong you are going to reject legal clients. (There is no possibility that you will accept illegal clients by programming error. SSL/TLS works.)

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
BenHi 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.
