Regarding Adobe Digital Signature

Hi
I am using Digital Signature in my application.
I have two signature field in my form.
SignatureField1 will be signed by the First person and then he/she will send that form to the Second person to be signed in the SignatureField2.
The Second Person will open the form and how can he/she validate that signature in the SignatureField1 is signed by First Person Only.
Is there a way of providing Public key of First person to the Second Person for validating the Signature of the First Person.
Regards
Chandran

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?

WDJ Adobe digital Signatures

Hello SDN,
I have to implement Digital signatures in my Webdynpro interactive forms. In sdn I found one example related to online Interactive form security but for offline I couldnt find.
In offline scenario, a user will send pdf form to customer or employee etc to fill the form and send it back.
1) Here how a receiver will know that he got the form, from an authorized person?
2) Once the form is filled and send it back, how receiver can validate whether the filled form came from an authorized person?
3) Also how exactly I can use digital signatures? what are the technical requirements for implementing digital signatures?(SSL is mandatory?)
Can some one guide me on this?
Appreciate your help.
With regards,
Ravi

Hi Ravi,
Digital signatures can also be created and verified as of Adobe Reader 5.1. Users can use the Adobe Acrobat Reader to display and print files in PDF format, whose content and appearance correspond to the paper version, on a cross-platform basis. The prerequisites for this are the use of the new Adobe Document Server for Reader Extensions and the replacement of SmartForms by Adobe Acrobat (this is still in development). SSF is not used.
Adobe Document Server for Reader Extensions assign additional usage rights to electronic forms that were created with Adobe Acrobat 5.0 and Adobe Form Designer 5.0. Digital signatures are a type of usage right.
Adobe Acrobat Reader 5.1 can be downloaded free-of-charge from Adobe's Web site, and processes the usage rights that were embedded in PDF forms by the Adobe Document Server for Reader Extensions.
for SSL service go through:[https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/media/uuid/40cacc80-c1fc-2a10-f8b5-9e33b1829552]

Installing ADE - cannot verify Adobe digital signature

On up-to-date 64-bit Windows 7 Home, I am unable to verify the software publisher when installing ADE 1.7.2, and so will not install the software. Both digitaleditions.exe (available via the ADE home page "Launch" button) and the "manual" install file setup.exe give warnings like so:
Do others experience the same message when trying to install ADE 1.7.2 on a clean system? Is there a certificate update I'm missing? Is the software really not recognizably signed?

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(s) Do I need Reader 10?

Hello all, we have Adobe Reader X here and I am having a problem regarding the digital signature that I think I'm creating, but nothing appears to be working for me. I don't think I'm missing a step (I've been viewing the instructions and just think Reader X is not the way).
So the real question is... is having Reader X hindering my digital signature escapades or am I really that dumb?
Thanks to all.

You don't "need" anything, but OS X 10.9 "Mavericks" incorporates significant performance improvements over earlier versions.
I don't want to use the GBs on my laptop.
I'm not sure what you mean by that. You will need a minimum of 8 GB free hard disk space to install it, but if you are concerned about that then you have bigger problems to address. After its installation is finished Mavericks will result in a negligible overall change to HD usage, including the amount of free space remaining.

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.

Projects & Digital Signatures

Hi Experts,
One of our Client deals with Projects.
According to my solution, every Project will have a Project Code and WH with same name.
1. The material lying at one project location some time is transfered to another Project location, and that has to be linked with Project Code for Costing purpose in Stock Transfers.
In SBO there can be only One Project linked, how to deal with this situation.
2. When the material is Purchase, it is booked as expense insted of current asset and they also want the quantity available.
Can i assign Expense account at Inventory account in G/L Determination, If so what all the things i should mind
3. My Client also wants Digital Signature of the approved person on the doc's. I have no idea about this, Can any help me about this.
Thanks in Advance
Regards,
Sandeep

Hi Sandeep
The best way to handle items to an expense account is to set them as non inventory items. This will automatically use the expense account for the account determination. The only problem is that SAP Business One will not have any on hand quantity for the item. You could try changing the stock account to be an expense account but I would not recommend this (as it seems you might have already done).
In the scenario you have, the best would be to purchase stock into the asset account and then use stock transfer to move it between projects or use goods issue to expense as the items are consumed for the project. That way you would know which items have being used or not. Please let me know what kind of projects these are, ie. construction over time, etc. How are customers billed, on milestones, etc.?
Note that you can change the allocated project code against the journal entry, though I would advise you to use this carefully as any mistakes would cause the project reports to be inaccurate.
As for the project on stock transfers, in the project column (form settings to activate) you can select a different project for each item in the rows. If the same item is being moved to 2 different locations, this will not be a problem as each project is also a warehouse and you must add 2 rows for the item and set a warehouse for each one.
With regards to digital signatures, this is not that easily handled in SAP Business One. The problem is how to relate a jpg or bmp image file (for example) to a specific user and not allow other users to access the file.
Kind regards

Certified digital signature

Does anyone know how I can assign a digital signature to a PDF document, a word or pages document or an email message using Snow leopard?
Thanks
OF

You can download Adobe Digital Signature here.
http://www.adobe.com/security/partners_cds.html
Goggle "Digital Signature for more"
Also, if you have Adobe Acrobat or Acrobat Pro it's built-in.
EDIT: There's nothing in SL and also note that not all institutions accept digital signatures.

Digital Signature Expiration

We are currently running 5.1 SP6 and are a little confussed with all the release notes that have been posted regarding the digital signature expiration as to whether or not our version will be affected by this. From the most current release notes, it sounds like versions BPC 7M SP3, BPC 5.1 SP7, BPC 5.1 SP8, and CPM 4.2 SP05 Patch 1 are the only ones that will be affected. Is this true?
It also sounds like it is more of a nusance than anything because you will recieve a warrning message if your security level is set to very high so you would have to change your security to a lower level. It doesn't sound like any system funcationality will be affected. Is this also true?

The digital signatures are for our excel components (add-ins). They must be signed (by verisign for example) in order for excel to allow them to run. The certificates expire, really they are not supposed to but there was a glitch in the these particular builds that allows them to expire, once they expire it could render BPC for Office unusable. This depends on Office's macro security, for example, if in excel your macro security is set to High, when you run BPC you will get a message that says the macros are unsigned and won't them be invoked. If you macro security is set to medium you will only get a warning and it will let BPC load if you click Ok on the warning.
These are the only versions that are effected.
Links to SAP notes with more information on the patch and to download the patch:
4.2 SP5 - https://service.sap.com/sap/support/notes/1334222
5.1 SP7 - https://service.sap.com/sap/support/notes/1334157
5.1 SP8 - https://service.sap.com/sap/support/notes/1334216
7.0 SP3 - https://service.sap.com/sap/support/notes/1334217
Hope this helps.

Digital signature is invalid

We have created adobe captivate video in "exe" format (Using Captivate 5). It has a adobe digital signature, but it is not proper (Invalid digital sign). So we want to remove that old digital sign and put our digital sign. How to remove digital sign from exe?
We used "FileUnsigner.exe" from here. It has removed that old digital sign and after that we have signed with our thawte digital sign. But after signing, that exe is not opening. How can we solve this issue?
Or any other option to publish that exe without digital signature? So that we can put our digital sign later.
Please anyone help as soon as possible

Hello there,
I'm not sure whether the signing would work with this exe but my question was if you are able to create the exe and playback without signing it.
Thanks,
Vish
