How to send digital signature from pdf form to fdf file?

Hi...
I already create the pdf form that contain digital signature field using ACROBAT XPRO...and now i would like to send data from pdf form to fdf file.I already manage to send data from other field except the digital signature.How to send the signature digital value to FDF file so that i can display it back to PDF file next time?Can anyone help me...i really need help right now...
tq..

hi....
thanks for replying..

It did work with earlier versions that did not perform a full save when a signature was applied. Since Acrobat/Reader now do a Save As when a signature is applied, there are no incremental saves to include in the FDF. This can still be useful for forms that haven't been signed, oddly enough, but since you cannot control whether the user performs a full save, it shouldn't be relied on for general use. The big problem is extracting the appended saves from the FDF so you can concatenate it to original document. The FDF Toolkit is the only thing I'm aware of that helps with this.
as u said that,Fdf tool kits can help to solve my problem.Can u send me the sample of code using java so that i can get the value using Fdf Tool kits?
Thanks..

How to inclulde digital signature in PDF outputs using XML Publisher

I'm working on AR invoice print report which is a custom report. One of the requirements of this report is to include the digital signature in the output which is in PDF format.
We have below code components for this custom report.
Oracle Report (RDF) - to extract the invoice data
RTF template - for report layout
Bursting file - to split the output into individual PDFs
Is there any document available to implement the digital signaure in my case?
I'm looking for the steps to implement this in my custom report using XML Publisher.

Take a look at the report designer's guide; section "Adding or Designating a Field for a Digital Signature" here:
http://download.oracle.com/docs/cd/E12844_01/doc/bip.1013/e12187.pdf
Thanks,
Bipuser
If I am not mistaken, this would require using PDF templates and use of Adobe Acrobat Professional.. Maybe others can chime in with other/better options..

How to Print Digital Signature in Smart forms.

Hi Experts,
Any one please help me how to use digital signatures in SMARTFORMS.?
Which are the tables used to store digital signatures and please any one have any demo program which prints the the digital signature using smartforms kindly let me know.
Thanks,
Sunil kairam.

Hi Sunil,
After doing some research in sdn and other sources i found the following result...
Digital Signatures are nothing but graphics that we can store in SAP and use in our Smart Forms.
For Example you can create a .bmp file of your signatures, upload it via SE78, and then use it in your Smart Forms in your Footer Area as "Authorized Signatory".
The Logic in the Print Program can be something as follows -
1. Maintain a Z Table having fields like PLANT, FORMID (Name of the SmartForm), USERID.
2. Before calling the Form, the validation is made for the Logged in User with the Z Table created.
3. If the User Entry exists in the Z-Table, the Form is called and the Signature Image is displayed in the Footer Block i.e. the Authorized Signature.
4. If user entry does not exist in the Z-Table then the message is displayed "You are not the Authorized for Printing the Form" and exits the Transaction.

Install Digital Signature on PDF Generator - Turn Key installation?

Hi,
I use TurnKey installation to install PDF Generator ES already. It works fine and it is in production line. Now I need to install Digital Signature ES. Can I use turn key installation? I suspect if I am doing so, the Jboss/MySQL will get overwrite and the perevious PDF Generator ES installation will be messed up, right? Any recommedention under this situation how to install Digital Signature ES?
Thanks a lot.

Hi,
I believe the correct approach will be to run the configuration manager, and simply add your key for DS, and go through the configuration. It shouldn't destroy your PDF G installation.

Digital Signature on PDF

Hi Folks!
I'd like to digitally sign a PDF document out of an ABAP program or class, just to ensure that the document was not modified by anyone.
In my program I hold the PDF as a binary stream in a XSTRING variable. I convert it into a binary table and use the function module 'SSF_KRN_SIGN_BY_AS' to sign this binary stream. In general, this is working fine (validating it with function module 'SSF_KRN_VERIFY' is successful).
But if I open the generated file with Acrobat Reader, no signature is found.
Obviously it does not work to sign the binary directly, as I did.
How can I create a digital signature on PDFs using ABAP? Do I have to convert it into ASCII or so before? Or: How must a signature be attached to a PDF file?
Our release is 620. Every little hint is appreciated.
Regards,
Torsten

How to get digital signature for Google Map geocoding V3 in PL/SQL?

Hi, Gurus:
    Could anyone provide me an example about how to generate digital signature for Google Maps service v3 in PL/SQL? We tried to upgrade our program using Google maps service from v2 to v3. We are using PL/SQl on background to send request to Google for geocoding. We found some sample code to register with digital signature, but none of them is based on PL/SQl. Notice I used Google business client ID "gme-XXX" and wallet.

Here is my code for V2. I notice in order to get signature, I need to use HMAC-SHA1 algorithm.

How to add digital Signature Field in cfdocument pdf files?

Hi,
We are generating pdf files using cfdocument to populate values and wondering how we can add digital signature field in those pdf files. Any help or comments would be deeply appreciated.
Thanks,
hismail786

Hi,
Yes, we have options to add digital signature to the pdf. We have one attribute called "Permissions" in "cfpdf" tag. If we provide permissions = 'AllowSecure', then system would allow digital signature for that pdf.
Please go though the docs for details info. I will post in details next.
Thanks

Digital signatures on PDFs

Sorry if I am posting this question in the wrong location, but hopefully someone who sees this message will be able to answer or point me in the right direction. I did perform a search and could not find a definitive answer.
There are documents in my company that will be circulated for approval and we would like to apply digital signatures to indicate that certain personnel have reviewed/approved these documents. I have the capability with Acrobat 3D version 8.1.5 to add digital signatures to a PDF. My question is: Is that true of all versions of Acrobat? If not, can anyone tell me the most recent version of Acrobat that has this capability or how I might find this out. I won't necessarily be the one creating the PDFs; thus, the question. Also, is there a better practice for indicating review/approval of a document?
Janice

Hi Janice,
First thing, the comment above is incorrect. You can most certainly add multiple signatures to a single PDF file, and one signature does not invalidate the next.
Onto your question; if you want to author the document with existing signature fields in a specific location you need Acrobat. However, once the fields exist you can “Reader enable” the document so the signature field can be signed using either Acrobat or Reader. If the file has been Reader enabled, then the user can create (place) a signature field wherever they like.
The ability to add signature fields has been in Acrobat since version 4 when digital signatures were introduced. The ability to sign using Reader has been around since version 5.1 (there was no 5.1 of Acrobat, only Reader). The ability for Acrobat to “Reader enable” a document for signing has been there since version 8.0.
Does this answer your question?

How to ensure Digital Signatures are not faked?

We are currently using some fairly archaic processes, whereby dynamic forms are completed digitally, printed, signed by hand, and then rescanned as static PDFs back onto our shared server. We are considering ways of streamlining this process, and one consideration is to use Digital Signatures. The one worry I have however is in how simple it appears to me to fake a digital signature of someone else. For example, a shared folder on the network contains PDF forms that must be approved by being signed off on by the CEO. If I add a digital signature field on this form, what would keep anyone with access to that folder from being able to open the file, click the signature field, but instead of using their own digital ID, creating a NEW digital ID with the name of the CEO, thereby making it appear that the CEO signed the form? I tested it and there doesn't seem to be any safeguard to keep this from happening.
Jo

You won't be able to fully verify a digital signature unless you add a user's certificate to your list of trusted certificates. You would only do this if you are certain of the source. See this previous discussion for more info: http://forums.adobe.com/thread/1118748

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

i hope there is a solution to this problem ,,

Alaa

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!!!
