Automatically renewing certificates for digital signatures

Is it possible to setup some form of system that automatically renews the user certificate for digital signatures? If so, where can i find information on this?

Hi - these are all reader extended through Livecycle ES Reader extensions and are signed by users in Reader. What I am asking is if anyone has an idea where this behaviour is declared, so that I can change it.

Programmatically Accessing Self Sign in Plug in for Digital Signature

Hello There,
We are looking forward to use “Adode Acrobat 9 Pro – Self Sign in Plug in” for one of the application to digitally sign PDF document i.e. appending signature to existing PDF document. We have gone through Adobe site (http://learn.adobe.com/wiki/download/attachments/52658564/samplesignatures.pdf?version=1 ; http://www.adobe.com/ap/epaper/tips/acrsignatures/ ) and explored “Tips and Techniques” along with screenshots.
We would like your help on following queries:
·         Can we programmatically from C#.NET access Adobe Object and create certificate for digital signature? If Yes, can you please provide pointers, references and sample code snippets? [We understand that we do not need to purchase SDK as Professional would be sufficient for digital PDF signature]
·         Does Adobe Pro installer provide DLL which can be leveraged in Code base i.e. C#.NET?
·         How does certificate management work for digital signing? Can third party like verisign, local computer / certificate from organization server work for digital PDF signature?
·         Please provide Technical Reference manual to use Adobe from C#.NET
·         Can you please throw some light and pointers on Licensing and Cost?
We are running on a deadline hence your quick help and response will be highly appreciated.
Thanks & Regards

Digital Signatures for cProjects Approval

Hi Folks,
I am on cProjects 4.5 and from what I understand there are 2 options for this based on whether or not I check the "Signature of Approval with User Certificate" box in Project Type config.
Unchecked - user is prompted for cProjects password and this works fine. Only issue for us is, we are on the portal and most likely cProjects password will be different and unknown to user. As per note 928527 this is standard behavior and tough luck for anybody on the portal.
Checked - use is given the ability to digitally sign the PDF approval document. When I select "sign" on the PDF I am given the ability to create a new ID or use an existing ID from a file, server etc. I created a new ID and signed the document. Once I do this and click the transfer button the system appears to hang. The progress indicator appears and keeps going.
Therefore my questions are:
1. Is there any additional config I need to do in cProjects. ADS or anywhere else?
2. How exactly does adobe digital signatures work? If anybody simply create a signature how does that provide any verification of authenticity?
Appreciate any help.
Thanks,
Lashan

Hi,
please see teh Configuration Content for cProjects 4.5 available in SAP Solution Manager and also as PDF attachment to SAP Note 1035436.
There it says:
Making Settings for the Approval
Use
You can use user certificates for digital signatures of approvals.
Prerequisites
● You are using Microsoft® Internet Explorer 6.0 or higher.
● You have a user certificate that is suitable for digital signatures (for example, the single
sign-on certificate).
● You have installed Adobe® Reader and Adobe Document Services.
Procedure
To verify the signature, enter the corresponding root certificate in the certificate list of the
Personal Security Environment (PSE, transaction STRUST). For more information, see the
documentation for the activity and the Adobe Document Services u2013 Configuration Guide NW
2004s on SAP Service Marketplace at service.sap.com/adobe u2192 Media Library u2192
Documentation.
In fact, what is described in the ADS documentation referenced above is that you have to install
the certificate also on the ADS.
Kind regards,
Florian

Digital Signature | Exchange Server 2013

Dear Expert,
My boss need to use Digital Signature in mail. Now, I use Exchange 2007, I have a plan to upgrade to Exchange 2013. What's the digital signature concept in Exchange Server 2013? What's the basic requirement?
Thanks in advance.

Digital signature is actually concept of Outlook or Outlook Web Access. You can implement it even without having Exchange. Anyway, you need to issue a certificate for digital signature to your boss either from your local CA or from public CA. After you install
certificate on his machine, you have to configure it in Outlook to be used for digital signing, as well as in OWA.
You can read more about digital signatures on my blog here : http://dizdarevic.ba/ddamirblog/?p=121
Please mark as helpful if you find my contribution useful or as an answer if it does answer your question. That will encourage me - and others - to take time out to help you. Thank you! Damir

priya_16

hi
i've the same problem. i've found this solution, but you need download a JCE Provider that allow you to read the explorer certificate store.
You can try this one: https://download.assembla.se/jceprovider/
and the code:
import se.assembla.*;
public class Listcerts {
     public static void list() throws Exception{
          java.security.Security.insertProviderAt(new se.assembla.jce.provider.ms.MSProvider(), 2);
          KeyStore ks = KeyStore.getInstance("MSKS","assembla");
          ks.load(null,null);
          X509Certificate cert=null;
          String alias=null;
          int count=0;
          for (java.util.Enumeration e=ks.aliases();e.hasMoreElements();){
                    alias=(String)e.nextElement();
                    cert=(X509Certificate)ks.getCertificate(alias);
                    System.out.println("\n Certificado alias"+alias+":");
                    System.out.println(cert);
               count++;
          System.out.println ("NUM CERTS="+count);
now, i need the same solution for Firefox browser XP
good luck

Digital Signatures and Certificates

I use Adobe Profession 8,
I installed a certifcate on my computer (certnew.cer) which has my informations and stuff on it.. ok so far. We have our own certificate server.
When i try to apply a signature on a pdf i created, my name is not on the list (Adobe). The only options i have is to create one or import one (.pfx, .p12). I dont mind importing one but it cant import .cer files.
Testing on another computer, after installing his certificate, his name was shown on the list in adobe.
Is there something that I can be doing wrong?
Is there are way to import a .cer file instead of a .pfx, .p12?
Is there an easy method of converting a .cer to .pfx (.p12) apart from using Windows Drivers Kit?

A cer file doesn't have a private key. It contains a public key and other certificate data. Signing requires a digital ID which includes both the cert/public key and the private key, and these are usually stored in pfx/p12 files.
Self-signed digital IDs are inherently less secure, but they can be made more secure if the recipient verifies the cert "thumbprints" that the signer shares ahead of time. . .
Comprehensive digital signature instructions exist in this doc:

Digital Signatures and Certificate Authorities

My users are wanting a way to sign PDF documents, and have them verified for internal and external receipients. We are currently using Acrobat 9 Standard. I know you can create signatures and 'self-sign' them, but those are only trusted if the receipient manually adds them to their 'Trusted' people.
From my reading, it looks like we need to purchase a third party code signing certificate, such as the following: http://www.verisign.com/code-signing/
My question is, what do we need to do to make that certificate availbable to my users to use for their signatures? I'm having a hard time finding documentation on this part.

Here's a good starting point for understanding how CDS and AATL work with Acrobat and Reader: http://learn.adobe.com/wiki/display/security/Digital+Signatures+101
Another option you should look into is Adobe EchoSign: http://blogs.adobe.com/acrobat/tag/echosign

How can I create digital signatures for my users using Windows 2008 Active Directory Certificate Services?

Hi,
I need to create local digital signatures for my users. How can I do that using W2k8 Active Directory Certificate Services? We are gonna sign Office 2010 documents.
What company offers cheap digital signatures solutions?
Thanks in advanced

Consider the following:
if you use your local CA server to issue digital signature certificates, there is no cost, because you are eligible to issue so many certificates as you need. However, documents signed by these certificates will be considered trusted only within your AD
forest and other machines that explicitly trust your local CA. Any external client will not trust your signatures.
If you want to make your signature trusted outside your network (say, in worldwide), you need to pruchase a certificate from trusted commercial CA (VeriSign, GoDaddy, GlobalSign, StartCom, etc) according to respective vendor price list. In that case you
don't need to have your local CA server, because it is not used. All certificate management is performed by the external CA. A most common scenario is to purchase signing certificate for particular departament principals (head managers) or few certificates
for a whole company (all documents are revised by a responsible person or persons who holds signing certificate and sign them after review).
so, it is not clear from your post what exactly you need.

Digital signature and certificates on Mail

Hello All,
I'm new using mac and i have a token with my digital certificate. So i wanna know:
How can i use subscribe or use a digital signature on Mail. How can i use my certificate to sign the message.
Thanks,
Altemir Pacheco

Altemir ... It's important that the certificate has been created for the e-mail address you want to use as sender e-mail. Your certificate needs to be imported into keychain. Keychain only accepts certificates in a number of formats, among them .p12. You can import in a number of ways, you can for example drop your .p12 file (the certificate) on the keychain icon. Then open keychain and check whether the certificate is visible under "my certificates". It has to appear there and it has to show as "valid" and not as "expired". Control-click on the certificate and set-up a new preferred identity for your e-mail address (I am not sure whether this step actually does any difference but give it a try). Close mail.app and restart mail.app. When you now create a new e-mail and you choose as sender e-mail the e-mail address for which you have the certificate then you should see on the right side, just below the subject line a little symbol which you can click on for activating the signature for the e-mail your writing. Hope all this works.

Message level security: difference digital signature and certificate

Hi everybody,
could anybody please explain the difference between <b>digital signature</b> and <b>certificate</b>?
Thans
Regards Mario

Mario,
A digital signature is an electronic signature that can be used to authenticate the identity of the sender of a message or the signer of a document, and possibly to ensure that the original content of the message or document that has been sent is unchanged. Digital signatures are easily transportable, cannot be imitated by someone else, and can be automatically time-stamped. The ability to ensure that the original signed message arrived means that the sender cannot easily repudiate it later.
A digital signature can be used with any kind of message, whether it is encrypted or not, simply so that the receiver can be sure of the sender's identity and that the message arrived intact. A digital certificate contains the digital signature of the certificate-issuing authority so that anyone can verify that the certificate is real.
where as
A digital certificate is an electronic "credit card" that establishes your credentials when doing business or other transactions on the Web. It is issued by a certification authority (CA). It contains your name, a serial number, expiration dates, a copy of the certificate holder's public key (used for encrypting messages and digital signatures), and the digital signature of the certificate-issuing authority so that a recipient can verify that the certificate is real. Some digital certificates conform to a standard, X.509. Digital certificates can be kept in registries so that authenticating users can look up other users' public keys.
hope it helps u.

Adobe XI when i use signature option i try to use rectangle, it gives option of certificate signature, does not give me webcam or digital signature or any other option to sign

when i use signature option i try to use rectangle, it gives option of certificate signature, does not give me webcam or digital signature or any other option to sign, have downgraded to Adobe X, no options show. Have upgraded back to XI no change. Free software I am using currently.

There are two types of signatures in PDF: electronic signatures, which are just images (stamps, text, image) and digital signatures.
If you want to use electronic signatures in Acrobat XI go to Fill&Sign->Place Signature. If a drag rectangle for the digital signature dialog comes up, you have selected digital signatures and Acrobat/Reader remembered it. Cancel it, go back to Fill&Sign->Place Signature and click a triangle to the left of "Place Signature". Then click on "Changed Saved Signature" and select the electronic signature type you want to use.
If you want to use digital signatures you can create custom digital signature appearance. Go to Edit->Preferences->Signatures->Creation&Appearance->More. In the "Appearances" section click "New". You will be presented with the dialog that allows you to create a custom appearance. If you want to put there your picture or image of your ink signature, you need to prepare this image as a file beforehand, select "Image" radio button, browse to the location of your image file. In Reader you can use only PDF as your image file. In Acrobat you can use many more file formats: JPEG, PNG, etc.
