Assign signature image to imported digital signature

I have a user who needs to be able to digitally sign documents for the State while using either his desktop or his laptop. We have the desktop Acrobat X configured properly, where when he digitally signs a document, the signature image is included in his digital certificate. To set up the signing on the laptop, I imported the .pfx file into Acrobat X on the laptop under Tools -> Sign & Certify -> More Sign & Certify ->Security Settings -> Digital IDs->Add ID-> from a file, where I browsed to the .pfx file. I added the signature image under Edit->Preferences->Security->New where I imported the .bmp signature image exactly as I did on the desktop. However, when he digitally signs a .pdf on the laptop, it just has a generic image of his name, not the signature image. Where am I failing?

When you sign, you should see where you can select the signature appearance name from a dropdown in the dialog.

How to add the new Signature Filter to LiveCycle Digital Signatures?

I have been wrote my own plugin for Adobe Reader.
This plugin creates signatures by cryptoalgorithm "GOST R 34.10-2001" instead of RSA used in Reader and Livecycle.
As a result, I can't validate signatures created by my plugin in the LiveCycle Digital Signatures. In the log file of JBoss are written next:
"Unsupported signature filter detected: GostSignaturePlugin".
My question is how to install a support of my signature filter in to the LiveCycle Digital Signatures?
Is it possible to install my existing plugin for adobe reader into LiveSycle, or I must to write new plugin for LiveSycle?

E-Pad and digital signatures

Folks,
Our company is implementing a new process wherein at the time of shipment, they would like to have the truck driver sign an e-Pad and the signature should be imported onto the bill-of-lading output. We have a customized delivery process and due to the volume of shipments, we do not want the truck drivers to spend anytime like saving the signature image to the desktop and then import into SAP etc.
We want the signature to be imported from the delivery screen (custom developed) onto the bill of lading output at the click of a button. We are using SAP version 4.7 and the e-Pad signature is from interlink electronics, who appear to be naive in SAP. We are open to look at other vendors for e-Pad or e-Signatures.
Hence, please help in the following ASAP:
1. Does SAP 4.7 have any limitations to import digital signatures?
2. Do anyone have any experience with e-Pad with interlink or can suggest any other vendor/product that can be readily used for this purpose?
Thanks and Regards,
Ram

Dynamic digital signature appearance

I searched but it seems like the subject hasn't been treated.
Ok, I've read "Digital Signature Appearance" by Adobe, and find out how to put my own image when displaying digital signatures.
Looking at some tutorial from the iText authors, I saw that it is possible to specify different images to display on the signature validation
status.
This is a very cool feature, but unfortunately it is not documented at all in Adobe's documents... (I had to found a patent description document
to get more info)
Here is what I've discovered: the signature appearance is organized in several layers (4 defined by Adobe, the others by the document producer),
painted sequencially when showing the document.
What I'm looking for is the way to the various layers are used: one may be used when the signature validation status is unknown, another when
the validation was successful and a last when it failed.
For now, all my layers are painted, no matter of the signature validation.
(description in "Dynamic preview of electronic signature" is on page 9)

The multiple-layer model for digital signature appearances in PDF was deprecated and is no longer part of the ISO standard for PDF (ISO 32000-1). The signature appearance is a STATIC thing - as it should be - and can not be changed "on the fly" by the content of the PDF.

Extracting the date value from digital signature/certificate

Hello,
I'd like to extract the date from the signature properties and copy the value over to the date field as shown in snapshot.
I am aware that we can change the appearance of the digital signature to make the date visible but in most case, it is too small to read on hardcopies.
We resort by manually typing in the date, zooming into PDF to read visible date (if any) associated with signature image, to click on the signature image to open the Signature Properties dialog, or to open the Signatures tab window docked to the left.
Manual typing in the date expose us to discrepancy problem when the PDF was created vs. the actual date the PDF was signed (date value associated with digital signature/certificate). For example, person A created a PDF with date typed in and then sent that file over to person B (approving the document), who may digitally sign it a few days later.
Hope I am making sense.
Regards,
Devin

You can get the data and other signature properties using the signatureInfo field method: http://livedocs.adobe.com/acrobat_sdk/9.1/Acrobat9_1_HTMLHelp/JS_API_AcroJS.88.756.html
But for you application you really should be setting the date field before the signature is applied, since changing it afterwards would invalidate the signature. You can execute a script that sets the valud of the data field with the current date using the "Signaute Signed" event, which you'll see as one of the tabs of the signature field properties dialog.

Second digital signature invalidates the first one

Hello to all,
I'm having some troubles adding a second digital signature to an already digitally signed PDF. The library that I'm using in order to handle the PDFs is an open source one, so I'm programmatically editing the PDFs. The first PDF I produce, PDF1 (the PDF with one signature), has a valid digital signature. The second PDF I produce, PDF2 (the PDF with the two signatures), has the second signature marked as valid, but the first one as invalid with the following error:
Error during signature verification.
Unexpected byte range values defining scope of signed data.
Details: The signature byte range is invalid
I've read and applied all the "best practices" on PDF digital signature, so I'm adding the second signature in incremental mode and I'm sure that the second PDF has no changes in the first part, this because if I make a binary comparison of PDF1 and PDF2, the first part of the PDF2 equals PDF1. So if you remove the incremental part from PDF2 (after the first %%EOF), you obtain PDF1 again with the valid digital signature. So the problem seems to be in something new in the incremental part of PDF2 that makes Acrobat Reader X thinks that the first digital signature is invalid.
If you want to see the three PDFs, here are the links:
The original PDF: https://docs.google.com/viewer?a=v&pid=explorer&chrome=true&srcid=0BzrgexS80Iq_ODQxZTY2MDk tNTQyYi00YTE0LTk0MTctYWMxNDFiOWY4MjA5&hl=en_US
PDF1: https://docs.google.com/viewer?a=v&pid=explorer&chrome=true&srcid=0BzrgexS80Iq_ZDQ3MTk1ZmI tNWI4NS00YzdhLTkxNmUtODk1NjVmY2M2NTVh&hl=en_US
PDF2: https://docs.google.com/viewer?a=v&pid=explorer&chrome=true&srcid=0BzrgexS80Iq_ZGM1YmZhMWE tY2JiYi00YzZkLWE5ZjItNzgwM2RlNzExYWE1&hl=en_US
Any help will be very apreciated. Best regards.

Hi,
I'm not sure if this helps, but I found something unusual with your PDF2. Just at the beginning of the second incremental update (with the new signature), the first object is added without a carriage return. This make the last line of the previous update looks like this:
%%EOF3 0 obj
May this leads to incorrect parsing and then invalidates the signature? Not sure about that, but as far as I can read offsets, your byte ranges are correct.

Digital Signatures: Multiple Tasks and Signers

Hello, All-
Context: We have a repair and overhaul operation that has several technicians performing maintenance. Basic workflow: product comes in, gets the paperwork for the specific maintenance, and then travels through the facility to be broken down, serviced, rebuilt, tested, and returned to service. We would like the "paperwork" to be all electronic (which we can do with Acrobat by using PDF documents), but there are several tasks that require a technician's signature. Not a digital signature for the WHOLE document, just a task in the document.
Objective: Multiple technicians signing off on mutilple tasks, all in one document.
Questions: Can we modify the document (i.e., add/insert pages) in Acrobat after a digital signature is applied using the Reader? Do those signing off on the tasks only need the Reader to create and apply the signature files? Can multiple signature files be stored in a centralized location, since technicians use work station machines (rather than a computer issued specifically to them)?
Doing some investigation for the best solution. Sorry for the series of long questions.

> "No. However, this can't be done in Reader under any circumstances... Reader is just that, a reader of PDF files. It can't edit them in any meaningful way, like add new pages (unless a special template was set up for this purpose)."
- I should have clarified: we would like to modify the document using the full Acrobat Suite after digital signature. Signing once locks the entire document from further edits.
> "Not 100% sure about that, but I think the answer is no. Signatures have to located on the local machine."
- That's a problem: then every technician needs a digital signature on every machine. Not suitable at an enterprise/department level.
I just found an answer to the basic concept, as it was answered just yesterday (http://forums.adobe.com/thread/1338837): I can leverge the Stamp feature and create a custom stamp to act as a signature. I can still modify the document after applying the stamp.
Now the test: can others remove my stamp?
Edit: Thanks for the help, BTW. I see you edited your answer to question #1. Again, maybe the stamp feature is sufficient?

Digital Signatures/Javascript After Signing?

Hello everyone,
I'm currently developing forms for my company, post processed through Adobe Acrobat 9 Standard, that require digital signatures. Working in the food industry requires compliance to specific FDA guidelines, specifically CFR 21 part 11. In order to meet the requirements I must develop an SOP (Standard Operating Procedure) that proves signatures are accurate and secure.
The process is tedious, and I have called a few meetings thus far to discuss some of the unforseen circumstances. During the discussion a question was brought up stating; What protects forms stored in the archives (3 years for compliance) from being corrupted by a disgruntled employee? Specifically, what stops an employee from clearing a digital signature? I realize we can set up file access rights to the forms to prevent such happenings, but majority of the forms are setup to hold 6 months to a year of info, thus wouldn't be archived until filled completely.
My question: Does anyone out there know of a javascript or trick to disable the "Clear Signature" function after signed? I've been searching and have turned up empty handed. Also, does anyone have any other javascripts that are used after digital signature occurs?
Thanks in advance for any help you can give me,

George,
Thanks for your response.
The issue is not if the file is deleted, the issue is if the files becomes "manipulated". I think "corrupted" was the wrong choice of words.
To explain: Any form that is completed has several digital signatures within the contents, depending on which QA Technicians complete the task (e.g. Calibrations, Metal Detector Settings, etc...). Forms are setup by days, weeks, or in some cases years, and have designated signature areas for the time period the test was conducted. So, after "John Smith" completes his portion of the form he is required to digital sign the document, after signing is complete all information is set to read only and cannot be altered unless the signature is deleted.
Digital signatures can be deleted in two ways:
1. The user who signed the document, based on active directory, has the ability to "clear signature". As and FYI: no other user is capable of deleting a signature signed by another employee. (does not apply to the form author)
2. The file creator can add a "Reset button" control, thus being able to delete any data specified.
So as I said I'm looking for a way to lock all signature functions, after sign is completed, even for the original signer. So if form "Calibration01" is currently being filled out and has signatures x,y,and z on it; I want to make sure if "x" is disgruntled they do not maliciously go and clear their signature. Also, I would like all fields associated with the signature to be locked without any way for the user to manipulate or revise data.
If anyone has any javascripts that run once signer digitally signs, it would be a great help,
Thanks,

Securing Digital Signatures and none of that other stuff

Hello. I am new to getting help from highly knowledgeable people in this type of forum. This will be my second question asked. The first time response was quick, correct, and succinct. I am grateful for your help and I thank you. I will need to find out how to close out the thread I initiated wit the first question. Now my second question will allow me to cut to the chase, (provided I learned correctly what my mentors told me when responding to my first question). Here it is: I want to lock my digital signature to a PDF document without the use of a third party CA or without becoming a do it yourself CA. From my perspective it would seem that these programs or services are far more that I need. I simply need to secure, lock don my digital signature of PDF document that I send out to government agencies. It’s a one way trip. Copies of the documents are provided to members of my association, again a one way trip. I need to have my digital signature integrated into the text of the document and secure as well as the PDF document itself. That is all I want to do; no tracking, no secured return digital signatures, etc. I prefer to by a add in or an easy to use software program, but if I absolutely have to, I can work with the “cloud”. Can anybody point me in the right direction? Eally need help.
Thanks for your consideration and past assistance.
HALO

There are many different types of digital signatures. I use digital signatures that are self-signed. They cannot be verified by the people that receive them, but guarentee the documents haven't been changed since signed.

Digital Signature and Rights Management

Hello all,
I'm following the document below and have a couple of questions on how to achieve that objective, that is how to provide a persistent document security.
http://www.adobe.com/security/pdfs/acrobat_livecycle_security_wp.pdf
I understand that I need to protect the PDF first using the Rights Management, then digitally sign it afterwards. This is pretty straight forward when using LC Digital Signatures, just build a process in LC Workbench, unlock the PDF temporary, send to Digital Signature operation, get it back and return the RM.
But when I use a third part digital signature solution? Is it possible to use another digital signature solution to get this - by defining a call to a webservice in workbench to sign the PDF.
For information: this digital signature solution complies with digital signatures in PDF.
Thanks in advance!
Diego

Hi Lee,
It's some module within IBM Lotus Notes. I'm trying to do the following in the Workbench:
With a RM document, Unlock it then invoke this 3rd part webservice in order to sign it. It's not working so far.
But if I follow your suggestion, when I re-RM the PDF wouldn't this invalidate the Digital Signature?
Thanks for the quick reply!

Digital Signature for QM Notification

Hi GURUS,
We have ECC 6.0 EHP 4 and want to implement Digital Signature functionality for Quality Notification (Type Q3). When I try to maintain Signature level under "Specify Digital Signature" node in SPRO, system is not allowing me to maintain level (neither header nor task level). It gives a message "Message no. Q0339 -Business operation is not allowed to be initial" Even if I ignore this message and save my entry, when I go back and check entry, entry is not maintained there...........i.e. entry is not saved.
As I am not able to maintain above entry I donu2019t know how to proceed.
Any input from all you SAP GURU will be great help indeed.
Thanks and regards,

MS Visual Basic for Applications will not apply digital signatures

When using Microsoft Visual Basic for Applications within any office application (Excel in this case), i cannot see the certificate store when creating digital certificates. It appears to be localised to the operating system but can't seem to find the issue.
To create the digital signature within Excel i normally go to Developer > Visual Basic > Tools > Digital Signature. When i select 'Choose', the certificates are not presented.
Has anyone experienced this?
Thanks in advance.

Hi,
As far as I know, If we want to use the digital signatures, we need to Digital Certificate for VBA Projects tool which a set of extra tools. I recommend we repair/reinstall the tool with a backup install CD.
Then, we may follow the below links to reset a digital signatures and add the digital signatures in the trust list(Location: File>Option>Trust center.) to test if it is helpful:

When attempting to Sign a pdf document I am not finding the option to use an image, I'm only able to use a digital signature. I want to use a jpg file.

I click on Fill & Sign Tools, then I click Place Signature. The instructions show a dialog box with four options however that does not happen. I am only presented with the option of importing a digital signature. How do I get to the option of importing an image (jpg) signature?
Robert

I assume you have a digital ID set up already. When you sign then you need to select how the signature is to appear and you can then select create new appearance. Not sure if this is what you are dealing withage.
