Digital signatures with Sapscript

Hello experts.
Had anyone worked with Sapscript using digital signatures?
Is this possible? I believe the Sapscript technology is old to support digital signatures.
The only solution in Sapscript would be to upload the signature images, wouldn't it?
Thank you in advance,
Andrés Sarcevic

Hi,
Is the digital signature in the form of a bmp or tiff ? If yes, then you can have a BDC of SE78(Graphics Management ), which will upload the graphics to the SAP system & then you can use it in your smart form or sap script dynamically.

Digital Signatures with SmartCards.

Hi guys,
Has anyone implemented in R/3 digital signatures with smartcards?
Currently I'm at customer side trying to implement digital signatures within workflow processes using ABAP SSF functions. The smartcard devices are already installed, but I can't read the data inside the smartcard, moreover, I can't link the smartcard device with R/3 and I don't know how to do it
I read in some Weblogs and documents that it is necessary a SAP-certified external security product. I believe this external security product is the software that comes inside of smartcard drivers CD. It is something like a little application on which we can sign in data and put our fingerprint.
I guess it is not supposed to develop an interface application between smartcard and R/3! When I started these developments I thought that I only needed to configure some environment variables to connect these devices with R/3 and then develop the ABAP flow logic with SSF Functions - Am I right?
Can anyone provide me some guidelines for this issue?
Thanks in advance,
Ricardo.

The SmartCard device is present at the frontend PC - and that's the place where the digital signature operation has to take place. Important is the "What You See Is What You Sign" principle: it has to be ensured that the data that is to be signed (using the private key stored on the SmartCard) is exactly the same as the one that is displayed to the user.
Notice: there is a different scenario where the server is signing the data (after prompting the user for userID and password and validating that information).
The signed data is then transported back to the server where it is stored (to ensure auditibility); usually you'll have to keep the (archived) data for years; the public key need to be archived as well.
Notice: it is possible to attach the certificate (-> public key) which has been used to sign the data to the signed data.

Digital Signature with Password

I created a digital signature with a password. Now, I've forgotten my password. How do I reset it so I can use it?

You can't reset it. Create a new signature.

Digital signatures with different versions of Reader

I have created a form which requires a digital signature for approval. Typically, an employee will complete the form in Reader and forward it to a supervisor for approval. The supervisor needs to sign it digitally and forward it to me.
The issue we are having is with those employees who are completing the form in Reader and the supervisor (or someone thereafter) has a more updated version of Reader and cannot sign the document. What can we do to stop this from happening? There is no practical way to keep everyone on the same version of Reader. We will have many more forms which require a signature, and we need this issue resolved. (I am using Adobe Acrobat 9 Pro to create the forms.)
Also, is there a way to verify the digital signature without using a third-party source? At this point, we know anyone can create a digital signature using someone's hand-written signature they found on another paper and we would like to prevent this from happening. We need to validate the person who used the digital signature is really that person.
Any help is appreciated! Thank you!

If you are creating your forms in Acrobat 9 Pro. and then Reader-enabling them for digital signatures, then recipients of the form will need to use at least version 8 of the Adobe Reader. Also, you'll need to do a few things during the authoring stage of your form, if your form changes by role (i.e., additional data is entered, annotations, or multiple signatures). Mainly you'll need to use a certification sig. for the first signature and set permitted changes after certifying.
You can find a lot more detail on best practices on developing forms for multiple signatures in the Digital Signature User Guide at:
http://www.adobe.com/devnet/acrobat/pdfs/acrobat_digsig_userguide_90.pdf
The guide also explains how to validate documents (authenticity validation and document integrity validation).

Digital Signatures with Adobe Reader

So i created an adobe form with acrobat 9 and sent it out for all to digitally sign. about half are getting an error when they try to sign it. "The credential selected for signature is invalid"
We are a government agency and use Common Access Cards (CAC) certificates to digitally sign with.
i was hoping someone out there could either point me to a good recource for adobe and digital signatures or to a possible fix.
now we have narrowed it down to the problem being with the specific machine. the user can digitally sign the document on another machine, but not on thier own machine. Also, no one else can sign the doc on thier machine either.
Thanks in advance!

issue still exists. ive been searching for some info on how adobe handles digital signatures, like what folders are created on the machine. im thinking maybe i can clear out the app data for acrobat or something. im at a loss at the moment.

Digital Signatures with Smart Cards

Hi folks,
It is my first time with digital signatures on R/3 system. Im at customer that uses smart cards (hardware cryptography). We are doing the SAPCRYPTOLIB and front end installations. After finish these tasks, we need to implement the signatures into 3 workflow processes. I already read the SSF programmers guide, API specifications and SSF user guide. But I still have some doubts:
The SSF profile is stored into smart card with private key information, but where are the public keys stored? (PAB Private Address Book of my trusted circle).
Do I need the CRLs? Note: this is only for workflow processes that run inside of customer landscape; this is not a B2B scenario.
We dont have clear yet how we sign the data; we are thinking sign a BOR object. Create an attribute and use it to pass the signer data. Note: for the customer, the objective is user authenticity guarantee.
The BOR object instance ends when the flows finish, so wee need to store the signed data for auditable reasons. A database table can be a good approach or there is another standard way?
P.S.: anyone have documentation about this subject, something like how-to with guidelines?
Thanks in advance,
Ricardo.

A way to clear digital signatures with presence = "hidden"

LCD 9, Dynamic forms using digital signatures, Reader 9x
I discovered this by accident, so wondering if this is a design feature or a bug.
I have a dynamic form and have sub-forms throughout it. I create a flowed subform for my digital signature that has fields to collect information and then place a fixed subform inside that that actually contains the signature field.
Page1 (flowed)
- SignatureBlocks (subform - flowed)
                - Field1 (textfield)
                - Field2 (textfield)
                -InitSig (subform - flowed)
                                -Field3 (textfield)
                                -Field 4(textfield)
                                                -FixedSub (subform - fixed)
                                                                -DigitalSig (signature field)
                -ReviseSect1 (checkbox)
                -CALCchkRevise (checkbox – calculated read only)
DigitalSig locks down various fields in the form.
My problem has always been that when the form goes to the next person for review there was no option to push the form back a state and allow the prior user to change info that was locked by DigitalSig. Until I discovered this:
If I place a checkbox (ReviseSect1) outside of “InitSig” subform and then run a calculation checkbox (CALCchkRevise) that sets the PRESENCE to “hidden” for InitSig if ReviseSect1 == 1, then toggle ReviseSect1 back to 0 my digital signature is cleared and thus all fields that were locked are now un-locked!
CAR-1601-FM01.Section1.SignatureBlocks.CALCchkRevise::calculate - (JavaScript, client)
if(ReviseSect1.rawValue == 1)
    SignatureBlocks.InitSig.presence = "hidden";
else
    SignatureBlocks.InitSig.presence = "visible";
Is this a design feature or a bug? I like it as I now can have a reviewer toggle the ReviseSect1 checkbox which erases the digital signature and thus opens all those locked fields back up for editing. Before I push this throughout my form (which has many signatures and review cycles) I want to be sure this is not a fluke that will go away when Adobe pushes its 1,037th update for the week for Reader. If you hide a subform that contains a digital signature then un-hide it is it the design feature of hidden/visible to clear the signature? Or is this a bug that will be patched?

A better way is to set two codes on the ReviseSect1 checkbox. CLICK sets the subform invisible and also sets the value of the checkbox to 0 (so that the user does not come back to un-click it and wipe out the signature again). Then put a MOUSE EXIT code that sets the subform to visible. In that way the user clicks the box and the signature subform hides, erasing the signature and un-locking the fields. As soon as they mouse out of the checkbox the subform with the signature becomes visible again. Nice.

How to validate XML Digital Signature with XML DB (o PL/SQL) in Oracle 11g

Hi,
Do you know if there is possibility to validate XML Digital Signature using XML DB (or PL/SQL) in Oracle 11g?
Let say I have CLOB/XMLType containing Digitally Signed XML, and I want to validate, that thsi is proper signature. I also have public key of signer (I could store it in CLOB or file or Oracle wallet).
Is it possible to do?
If there is need to install additional component - then which one?

Hi,
this is what i got from someone...
but the links he gave are not opening up...
u have to place a picture there and have to load the digital signatures as Jpegs on to the server to OA top
and have to refer them in the XML for dynamically get the signature on the reports
when u select the properties of the picture placed in the XML template,
there will be one tab with "URL"... in that u have to give the path for that jpegs
Pls refer the following documents for enabling digital signature on pdf documents.

(Implementing a Digital Signature
Is the BI Publisher installed on your instance of version 10.1.3.4 or higher?
Pls procure a digital signature as soon as possible. The process can take time. OR we could use any certificate that you already might have OR generate a certificate using Oracle Certificate Authority for demo.

Digital Signature with Flex

Hi,
I'm developing a secure flex application in order to mantain user and password catalog, i need to create SSL Transport channel and a non-repudiation request mechanism. I already review that i could achieve first with HTTP Service for SSL and the second with XML Digital Signature but only i find java and .NET APIs for last. Is there an equivalent flex mechanism (or Action Script) to achieve XML Digital Signature?
Thanks in advance.

Some time ago I was researching for this but never fallowed through it... I can only give some hints I've found during the process, hope they help:
http://code.google.com/p/as3crypto/ (this is a lib that handles a lot of encryption methods including public encryption)

Digital signature with HSM

Hi all,
As you know BI Publisher allows applying digital signature on PDF document. It can be configured vai GUI or you can apply digital signature using Java API supplied with BI Publisher. It's quite straightforward procedure. But problems are coming when you try to make the signature complaint with EU Commission Directive 1999/93/EC or similar US legislature. I do not think everyone is interested in all the details. But the difficulties we have confronted with are related to the fact that BI Publisher API can deal only with Private Key and Certificate stored in PKCS#12 storage. And most of Certification Service providers provide all these data in HSM devices that support only PKCS#11 interface and private key is not extractable.
So questions are:
-does anyone aware of supported integration of BI Publisher with HSM devices?
-may be there is any alternative solution to feed BI Publisher with token from PKCS#11 complaint HSM device.
-Is there certification service providers who provide certificates in PKCS#12 format?
Thanks in advance,
Shavkat

You can't reset it. Create a new signature.

Digital Signature with PDF problem

I followed the steps in Administrator's Guide for Oracle Business Intelligence Publisher to assign PDF files with Digital Signature ,,
however when i schedule a new job it succeeds but i don't get my digital signature ,, but i get an empty square with nothing written in it.
however, when i tried to sign my PDF directly form Adobe and it worked ok ,, so there is no problem with my PSK file,,
i have uploaded an output sample (you can notice the square, where the DS should be, in the top-center area)
the sample output
http://www.mediafire.com/?68kt60sxx3i3aie
i hope there is a solution to this problem ,,

Gerorge, thank you so much. I have since upgreaded to Pro and am now trying to figure out how to use the digital signatures correctly. I have sent out a test form and had a coworker complete, sign and send back but when I open up the form it says I have a signature error. and then i get this pop up when I click on the signature
What am I doing wrong? I work in HR and need these to be valid signatures. Thank you so much in advance!!!

TIA - Willem

I believe PIX supports simple Dig Sig.

Can't create a digital signature with acrobat 8

We have acrobat 8. My husband has a digital signature but when I try to electronically sign, his digital signature pops up and does not give me the option to create my own. How can I create my own digital signature on this software?

I don't have Acrobat 8, but in Acrobat 7 & 9 it's under "Advanced > Security Settings", which prings up a window where you can add a digital ID.
