Print or Submit Depending on if PDF has digital signature

hello everyone!!
i have a quick question and please let me know if i am posting this in the wrong area.
i have a pdf form created in Acrobat 7 but we need to reader rights enabled so I have since them downloaded acrobat pro 9 and revamped it. it works great for those who have reader to give them the ability to fill it out and send it back as the complete PDF. however, what i would like to do is have a "submit" button that checks to see if the document has a digital signature. if it does, i want it to submit to an email address. If it does not have a digital signature, I want the button to print the form so the user can sign it and send it in. I have searched the web and unfortunately haven't found much on this. My question is: is this even possible? If it is, could someone point me in the right direction or give a few tips on how to start. any info at all would be greatly appreciated!!
Thanks much!
Mandy Sky

Well thanks to the folks who took a look at this post....I've gotten no replies and need to move on...
Since I have posted this, I have found that it is possible so I'm going to try and muddle my way through it.
Cheers~

Print MS Access report to PDF with digital signatures.

I know it is possible to print a Microsoft Access report to a PDF file. However, we need to be able to add digital signatures to the resulting PDF. Is it possible to predefine the PDF signature fields in the Access database so that when the report is printed to PDF it is ready from employees to sign off on the PDF?

This is doable with the ability to do a security.importfromfile which provides the ability to import a certificate.
This is critical.
Just create the PDF and then open it up in Access. Be sure to have a reference to the Acrobat Type library.

PDF with Digital Signatures

I am currently using classic asp and I need to fill out an existing pdf with data from the database. The form also contains two signatures. I just need to fill in the form, save it so I can email it to the the customer. I tried using the fdf toolkit - but my form has text fields that can be 20 characters or 4000. The multiline function in adobe forms isn't working correctly and it cuts it off when you print.
I could create the form in livecycle, and generate the data in xml, but I am so new to adobe, I don't know how to programatically load the file and save it to the server.
I have another program I've tried where I can generate fdf code I think it's fpdf (the php version that was changed to asp) - but I need to know how to generate a digital signature.
I've tried pdftk - I tried to merge the data with the signature - but ended up with permission issues.
I have been working on this problem for several weeks and could really use some help.

Bill,
I'm trying to create a dynamic document using data from the database to generate the pdf, the pdf also needs to containg two signatures for signing. I've looked at every way possible to do this. Currently, my greatest success has come from using the fdf toolkit, but the sizing of the fields (could be 20 chars, could be 4000 chars) leaves me with a very ugly form.
The form I am using already contains the two signature blocks - but I am at a loss on how to populate a pdf form that resides on the webserver with data from the database.
Bill, can you help?

Adobe PDF/Acroforms & Digital signatures/Integrity/Authentication/Non repudiation

Hi folks,
I have been investigation the feasibility of using PDF as a customer-facing data collection mechanism, starting with Acroforms for a pilot, initially at least (we may consider XFA/Livecycle in a later phase).
I've got a demo application up and running using the FDF toolkit, presenting PDF forms to the web user, collecting and processing/storing the collected data etc.
My question is around how this process can be secured.
(Q1) (This may be strictly a web dev question, please ignore if considered not relevant here) : If the web application communicates over HTTPS, then the conversation between client & server is secure (encrypted at least, so that others cant sniff the content?) - but it does not necessarily authenticate the end user to the server?
(Q2) If we wish to ensure that the FDF data Submitted from the PDF form (via submit button to an ASP.NET url) is (a) known to be authentic from a particular known user, and (b) signed in some way to be non-repudiatable ... how can be do this with FDF ? If we re-generate a flat PDF document from the data they entered, is there any digital signature mechanism that can be employed for the public end-user to "sign" the PDF document in a manner that ensure Integrity/Authentication/Non repudiation ?
any pointers to Adobe or Third party toolkits, products etc. ?
best regards & thanks,
Aidan.

Q1. That's right. But if the form includes fields for a username/password, this could be sent along with the rest of the data and used to authenticate the user. Or you could use other common means, but as you said, this has nothing to do with Acrobat.
Q2. FDF can contain digital signature data. So the form would have to contain a signature field and the user would have to sign it. Assuming a self-signed signature, it's up to you whether to trust such a signature. The signed PDF is constructed from the original PDF that was served by concatenating the appended saves contained in the FDF. You can then validate the signature.

Dynamic PDFs with Digital Signatures?

LCD 9 – Acrobat 9 standard/Pro
Looking for the definitive answer on this one. My PDFs have a need to be both dynamic and use multiple digital signatures. For now I design as static with multi dig sig and deal with break-out forms and such via a portfolio.
It would be nice if I could design a form that has both flowable sections (think dynamically added rows in a table using script, or even simple textfields that expand as you fill them up via flowed content areas) and these digital signatures. As soon as I make that PDF dynamic the signatures are immediately invalidated as the form shows changes.
Is there any workaround to this? Some of the process I have to design for need flowed fields, and all require digital signatures on the form. We use Entrust as the security for dig sig - and that will not change so cannot use any inherent Adobe signature security methods.
Thanks,
Jim

Hi Jim,
Yes, the file was created for Acrobat 10, but other than the warning you see on file open it will behave the same way in 9.x as it does in 10. However that said, you don't want to look at the file in Acrobat because you can't edit it or see the layout there. You need to view the file in LiveCycle Designer which gets installed along with Acrobat, and when you do get the file open in Designer it won't complain. Once you get the file open in Acrobat select the Forms > Edit Form in Designer menu item and that's where you can see the properties used to get page flow to work.
I've attached another copy without any data that won't complain when you open it in Acrobat. It is for all intents and purposes the same file, the only reason there are fewer pages is due to the lack of data in the table.

Save as PDF, allow digital signatures in Reader

After saving the pdf from Pages, security permissions do not allow for digital signatures in Adobe Reader. How do I change this without having to use the full version of Adobe Acrobat?
...Bruce...

Hi Bruce,
Although you are creating the pdf from Pages, it's not Pages that is actually doing the conversion. Pages (and any other application for which pdf is not the 'native' file format) is using code that is part of the OS X package to convert the document to a pdf file.
If that code includes the capability of allowing digital signatures, Apple hasn't bothered to mention the fact in the Pages '09 User Guide. The only pdf option listed there for Export PDF is reduction of file size by resampling image files.
As the conversion is done with OS X bundled code, shared by all applications, you might find more useful answers in the Mac OS X v10.7 Lion community.

Barry

Adobe slow to open PDF with digital signature

Hi,
We have recently added a digital signature to our PDF reports for security. Adobe takes an age to open the PDF on some PC's but instant on others. Can anyone offer any assistance to this problem.
Thanks.

You may be correct. Just opened up a PDF on my home computer and it was almost instant and it was very quick to validate the signature as well.
I have the latest version on my home PC but the work one is an old version of adobe reader for sure. I will try tomorrow and let you know.

Export to pdf w digital signature

Hi, folks.Does CR have an api for adding a digital signature to a report that is exported to a pdf? I will be using VS.NET 2005 w/ CR to programmatically populate the reports. After some research and searching on the web, I haven't seen anything explaining how to get the sig into the generated pdfs. I will also have access to a standalone Pro version of CR, but it doesn't seem to have a way of doing this either, unless I missed it in the documentation. Does the developer edition of CR have an api for this? My client requires a digitally signed pdf document. There must be a way of programmatically doing this, right? Thanks, Lee... 

 It's not within the current CR.NET API, but there are third-party libs that allow you to post-process a PDF file created by CR.NET. There's Adobe's library, and even an open-source (<a href="http://www.codeproject.com/useritems/Esignature.asp" target="_blank">iTextSharp</a>) one.Sincerely,Ted Ueda

PDF Template Digital Signature Error

BI Pub 11.1.1.5.0 --
Just wondering if anyone has found a workaround to the error below ...
In order for end users to digitally sign a pdf temple field in adobe reader, adobe pro has to "Extend features to Adobe Reader" on the template but that functionality breaks when BI Publisher modifies the form by layering data into it. So when the form is opened the user will get an error like:
"This document has enabled extended features in Adobe Acrobat. The document has been changed since it was created and use of extended features is no longer available. Contact the original author."
Has anyone been able to successfully implement this functionality?

Upgrading a sensor via VMS is part of our standard testing procedure for a new signature update and it passed the test!
Unfortunately, for some reasons, the checksum of the file published on Cisco.com doesn't match the checksum of the file we have tested.
My apologies for any inconvenience it could have caused, we are working to have this fixed asap!
I'll post again once this has been done.

Adobe Acrobat Pro X - Pages options grayed out on PDFs with digital signatures

When we apply a signature to a PDF in Acrobat Pro X, it disables all the options (e.g., rotate, delete, replace, etc.) except for "Extract". This was not an issue with Acrobat v8. Does anyone have a solution to this problem?

That's because all of the operations you mentioned that are disabled, if run, would invalidate the signature. The bug was in version 8 in that we should never allowed the user to modify the signed bytes and break the signature.

We use web service handlers to add and verify digital signatures. The request message seems to be making it to the web service but is failing before reaching the web service handler which verifies the digital signature.
Everything works fine when we don't add the digital signatures. The SOAP message without the digital signature doesn't have the SOAP header. I've listed the SOAP message with the digital signature below.

We are using Oracle AS 10.1.3.3.0, WSDL 1.1, and SOAP 1.2. Everything works fine with WSDL 1.1 and SOAP 1.1.

Take a look 'How to Use a Custom Serializer with Oracle Application Server Web Services' [1].
In your case, you should be looking at BeanMultiRefSerializer (org.apache.soap.encoding.soapenc), which will serialize your data using href and providing a way to deal with cycles.
All the best,

Export Page as PDF after Digital Signature

Hi there!
I'm looking for a script that will export the page that is being signed (Page 2 of an 85 page document) after it is digitally signed.
Thanks!

Oh really? That's so odd! I can set up a button that extracts the page with an inputted signature, but I suppose that since that will be digitally signed, it will not work that way?
What I'm thinking is that when I digitally sign the document, it saves a new version of it that IS signed. I'm hoping to do that for just that exact page and not the entire document.

Is it possible to circumvent read-only after a pdf has been signed?

Hi, my pdf has a signature field. In the signed event I have make all fields read-only. Is it possible for someone to come along and make them not read-only anymore? It seems the easiest way to make my document tamper-proof. Thank you.

goodprogramming wrote:
It's not the file that is set to read-only at the OS level. The signature field has an event for signed. Once that occurs I have the checkbox selected that says mark all fields as read-only. I want to be sure it is really read-only and that there is no way to make it non-read-only.
save as does not change the read onlyness of the pdf. I have tried this.
It shouldn't matter.
Making changes to the file after the signature is added will invalidate the signature. You'll know someone has been messing around if the sig is invalidated.
Even if you have a reason to do what you want, you can't. At least not without a very expensive Digital Rights Management solution plus a server to run it.

Securing pdf document with digital signatures

I have a pdf document that has digital signatures. We need to secure it so no one who has input their digital signature can go back in later, delete their signature and then 're-sign' it. But I get an error message telling me I can't secure the document because it has digital signatures.
Is there any way to secure the document so only I can secure/unsecure it after digital signatures have been input?
Thanks!

You don't need to use document encryption to lock the PDF file. You can set the signature field properties to mark all fields as read-only at signature creation. Try this:
Select the Tools > Toolbars > Advanced Editing menu item
Click the Select Object tool on the Advanced editing toolbar (it's the arrow icon)
Right mouse click on the signature field and select Properties from the pop-up menu
Select the Signed tab on the Digital Signature Properties dialog
Select the Mark as read-only radio button and All fields from the corresponding drop-down list
Click the Close button on the Digital Signature Properties dialog
Select the File > Save As menu item and save a copy (in other words, leave the original copy as is in case you find you locked yourself out of the document, that way you'll have a fall-back recovery option)
Good luck,
Steve

PDF by email in 46C with digital signature

Hi all,
can anyone tell me if it is possible to send a PDF with digital signature from SAP in 4.6C?
I'm converting a spool order into PDF document, and send it by email using FM SO_NEW_DOCUMENT_ATT_SEND_API1..
Best Regards,
Pedro

Thanks for the reference to the digsig user guide. I've reviewed this documentation and the majority of it I had already tried however one TIP that is in this document that I hadn't seen before points to setting up a FDF file to import AD secure to easily import the ID's
More specifically, I have configured LDAP and the Security settings in Adobe Pro and when attempting to connect to our LDAP server is when I run into the issue. I am not able to connect. Is there any additional information that you know of that can shed some light on LDAP configuration with Adobe PDF forms for digital id's?
