Applying a timestamp to a Digital Signature in Office

Hello,
I want to apply een digital signature to a Worddocument or to the macromodule of a Worddocument.
Because the certificate expires after a year, i want to add a timestamp.
Now I read in the article "Digital signatures in Office 2010" that there are two registry settings to control the type of signature Office creates: XAdESLevel and MinXAdESLevel.
So if I want to a signature with a timestamp i have to add the registry settings:
XAdESLevel = 2 (REG_DWORD)
MinXAdESLevel = 2 (REG_DWORD).
Is that all, or do i need tot provide Office with a time stamp server?
(I don't think i have a time stamp server).
Kind regards,

Hi,
As far as I know, if we want to use the time stamp functionality with digital signatures, we must complete the following:
Set up a time stamp server that is compliant with RFC 3161
Use the Group Policy setting, Specify server name, to enter the location of the time stamp server on the network.
On the other words, we need a time stamp server.

Timestamp digital signature

Hi,
We have implemented the digital signature that is triggered by setting a specify document status. We see however that the timestamp of the digital signature differs for other changes in document attributes. The timestamp for the digital signature is set by the Timezone-time. Both times can be looked up in the menu System-Status. The timestamp for the other changes are defined by the System time. Does anybody know how to align the two?

Systemtime and solution manager timezone were not in sync.

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!

Reducing File Size After Applying Digital Signature

I have a dynamic form created in Live Cycle Designer ES 8.2, reader extended in Acrobat Pro 9.4 and being filled in and signed in Reader 9.4. The form has multiple (10+) digital signature fields. In some cases, images (jpeg, tiff) are inserted into the form before it is circulated for signatures. Everytime a signature is applied, the file size grows based on the size of the images that have been attached as it seems to be embedding a signed version of the form each time a signature is applied. After a few signatures are applied, the file size can grow to be quite large. Is there a way to prevent it from doing this everytime a signature is applied so that the file can be kept to a more manageable size?

Go into the importing tab, and set the options to Mp3 at a lower bitrate, then go to your song and choose Convert to Mp3 - it will then create another copy at a lower bitrate - leaving the high quality original - you can then burn the smaller one to your CD - it shouldn't take long to convert.

Applying Digital signature for SFTP protocal

Hi,
There is an requirement in the project that transfer of digital signatured document from client FTP site to the Bank FTP site. I have implemented the solution for tansfer of any document from client FTP site to bank FTP site. However not have any clue on how to apply digital signature before transferring using SFTP protocal.
I have gone through b2b guide and found that We can apply digital signature and message encryption for only AS1/2, ebMS-1.0/2.0 and RosettaNet-01.10/V02.00 Protocols. Security tab is enabled when we select the above protocols only.
Please shed some light on how to provide the solution for this requirement.

MS Visual Basic for Applications will not apply digital signatures

When using Microsoft Visual Basic for Applications within any office application (Excel in this case), i cannot see the certificate store when creating digital certificates. It appears to be localised to the operating system but can't seem to find the issue.
To create the digital signature within Excel i normally go to Developer > Visual Basic > Tools > Digital Signature. When i select 'Choose', the certificates are not presented.
Has anyone experienced this?
Thanks in advance.

Hi,
As far as I know, If we want to use the digital signatures, we need to Digital Certificate for VBA Projects tool which a set of extra tools. I recommend we repair/reinstall the tool with a backup install CD.
Then, we may follow the below links to reset a digital signatures and add the digital signatures in the trust list(Location: File>Option>Trust center.) to test if it is helpful:

How do I apply the digital signature (Adobe.PPKLite)?

I'm trying to fill out a complaint form to send to the North Carolina DMV. I have to send the form electronically as I have electronic format evidence (texts, facebook conversations, etc.) that i have to send with it. They require the Adobe.PPKLite format for the digital signature and I'm confused on how to use it. Link to the form I'm trying to fill out is below.

Validating digital signatures successfull on Win7 but fails on Vista/XP/W2K3

Microsoft has announced (Security Advisory 2880823: Recommendation to discontinue use of SHA-1) that
they will stop recognizing the validity of SHA-1 based certificates after 2016. Microsoft started to sign their files with digital signatures which use the stronger SHA-2 hashing algorithm. For the countersignatures (Time Stamping Authenticode Signatures)
they also use SHA-256. These certificates can be validated fine on Windows 7/8 but can't be validated on Windows Vista, Windows XP and Windows Server 2003R2. The status of certificates in the Certification Path are OK but on the older operating systems the
countersignature seem to be missing... See the forum thread
EMET 4.1 Update 1: 'The digital signature of the object did not verify.' on Vista/XP in the
Enhanced Mitigation Experience Toolkit (EMET) Support Forum for several screenshots.
Can someone explain this behavior and maybe provide a solution?

Hi,
It looks like it is related with this
https://technet.microsoft.com/library/security/2749655
This issue might be caused by a missing timestamp Enhanced Key Usage (EKU) extension during certificate generation and signing of Microsoft core components and software.
Microsoft is aware of an issue involving specific digital certificates that were generated by Microsoft without proper timestamp attributes. These digital certificates were later used to sign some Microsoft core components and software binaries. This
could cause compatibility issues between affected binaries and Microsoft Windows. While this is not a security issue, because the digital signature on files produced and signed by Microsoft will expire prematurely, this issue could adversely impact the ability
to properly install and uninstall affected Microsoft components and security updates.
So have you applied this update on XP\Vista\Server 2003?
http://support.microsoft.com/kb/2749655
This update will help to ensure the continued functionality of all software that was signed with a specific certificate that did not use a timestamp Enhanced Key Usage (EKU) extension. To extend their functionality, WinVerifyTrust will ignore the lack of
a timestamp EKU for these specific X.509 signatures.

Digital signature fields in AutoCAD?

Is there any way to insert a digital signature field in AutoCAD and then make the PDF? That way it is ready for the engineer's electronic digital signature and timestamp?

No. You can't have multiple digital signature fields with the same namein the same document as you can with other types of fields. Since a digital signature applies to the entire document, not just a page, pages, or section of a page, it doesn't really make sense.

SOAP encryption. should digital signature added before or after encryption?

I'm developing secure web services. I want to add timestamp, digital signature and encrypt the soap message. What's the order? 1. timestamp, 2. signature, 3. encryption?

Assuming the API you are using allows you to apply all pieces in any order, I would encrypt before signing. Signature verification should be quicker than decrypting and if the signature fails, you don't have to bother decrypting. If you think the timestamp is something confidential, add that before you encrypt, otherwise not.
Edit: Though I don't think there's really a "right" or "wrong" way to do it. There's trade-offs no matter which way you do it. If you encrypt last then someone looking at the message just sees an arbitrary blob of bytes...

Digital Signature Issues

Hi, I am brand new to this forum, But this is my second question. I am running Abobe Acrobat Pro 9.0.
          I have been tasked with making a document that is Digital Signature ready.
          I was able to make a digital signature for my document. However, I have two warning that come up.
               Once the document is signed, a blue bar shows up at the top of the page. It has the following statement: "At least one signature has problems, Please fill out the following form. If you are the form author, choose distribute form in the forms menu to send it to your recipients"
                When expanding on the yellow triangle, There is one green check mark (with a statement that says: "The document has not been modified since this signature was applied".
                    Two warnings show up:
                     1) "The signers identiy is unknown because it has not been included in your list of trusted identities and none of its parent certificates are trusted identities".
                     2) " Signature date/time are from the clock on the signers computer".
               George, I have not been able to paste the Javascripts from that freeware into my Adobe program. I am not sure if it is the permissions set in the Adobe program or the restrictions my company has with altering computer software.
          Is there something that I might be able to do to remove the warnings?
          Very Respectfully: Rossknechtt,

For #1, it will always show that for self-signed certificates that you have not yet chosen to trust. When you add the identity to your list of trusted identities
and choose to trust it as a trusted root.
For #2, it will say that unless the time was retrieved from a timestamp server when the signature was applied. So what you're seeing is normal if one was not used.
More information on all of this is in the Acrobat Help document.
