Digital signatures and form certification

Hi,
Activate enhanced functions such as comments
So called usage rights can be apllied to a PDF form to enable additional functionality in the free Reader. The example here is a commenting menu.
Digital signatures
Is a client side digital signature to sign the content of a document.
form certification
Proof of origin of a document. A PDF form is certified on the sever after creation. If you trust the person/organization that certified the document you can be sure that the PDF document does not misbehave.
Hope this helps,

When trying to send a pdf for multiple digital signatures, it keeps erroring out. What are some reasons?

I am having trouble sending out a document for digital signatures for multiple people. I enter the signature fields and click on Distribute. It then allows me to choose the receiving parties. I click on <SEND> and it processes for a moment and then I receive the following two errors: "Failed to send" followed by "Form distribution is aborted". It was working for me earlier and isn't now. I am fairly new to Acrobat and especially Digital Signatures. What are some possible reasons I am getting this error?

I finally got the document to send out by unclicking the "Collect name & email from recipients to provide optimal tracking" button, however, the responses come in as anonymous, so it's not real helpful with tracking my responses. Plus, I don't know if I'll encounter problems with follow up. The normal tracking system allows me to resend a message to those who have not responded. Now I guess I would just resend the request to those I have determined have not signed. Still working through the bugs but I'll update what I know and figure out here. Perhaps I will come to a solid solution and give a better summary.
As of now, I am sending and receiving responses... but the recipients have to change the received file to save as it is coming to them as read-only. Seems like this should be a whole lot less complicated.

Hi, I am oracle apps HRMS Technical consultant.I wanted to know ,can we implement Digital Signatures in Oracle apps 11i XML Reports.if yes what is the approach to do so ? Your quick response is appreciated. Regards , Aasma Sayyad.

Hi,
I am Oracle Apps HRMS Technical Consultant.
I wanted to know,if we can implement Digital Signatures in XML Reports for Oracle Apps HRMS 11i Aplication.
If yes,what is the approach to do so.

Hi Aasma,
The standard BI Publisher is part of EBS applications.
Most of the EBS reports(R12) are based on BI Publisher.
If you check the responsibility 'XML Publisher Administrator' you will see all the templates used in the application.
Your technical team should already know this.
On the other hand OBIEE would need separate licences.
But for you BI Publisher would do.

What is the certification authority, the third party that can confirm the digital signature?

I created a nice electronic signature, that I now regularly use and add to every document. I was told that a signature needs to be issued by a verification authority, a third party that is able to verify the signature, certificate. I created a free certificate at CAcert.org and tried to combine it with the adobe signature certificate file, but it doesnt support .cer and .crt files. Is the Adobe the certification authority in this case since i created signature in the Adobe software? Its not a big deal, I just want everything to be correct since I use the signature in official documents now (instead of scanning a signed document) ... Thanks for any info, ideas or help.

Each Digital Certificate has a pair of private and public keys used for encryption/decryption. The private key belongs to the certificate owner and should be kept secret. It is protected by a password. The public key can be used by anyone. Digital certificates come in two flavors: one that contains both private and public key and one that contains only public key.
When you create a digital signature the signing process uses the private key to encrypt the signed content digest and the public key is used to decrypt it. So, only you can encrypt signed content with your certificate that has both private and private keys and anyone can decrypt it to validate the signature using certificate that has only public key. Usually, this certificate with the public key only is embedded in the digital signature, so that anyone can use it for decryption.
The .cer certificate contains only public key. Certificates with both private and public keys usually have extensions .pfx or .p12. You need one of those to sign.
CAcert.org issues only public key certificates. so you cannot use its certificates for digital signing.
Adobe is not a general purpose certification authority. It issues some certificates for internal use only.
Acrobat has a feature that allows you to create so-called self-signed certificates with both private and public keys but these certificates can be used only in a limited way. They do not provide the means to authenticate the real certificate owner nor revoke a certificate if it is stolen.
Generally, a digital signature asserts three main features:
1. Document integrity (document has not been changes since it had been signed),
2. Authentication (the signer is indeed what the certificate says)
3. Non-repudiation (the signature author cannot deny that he signed it: this is achieved via certificate revocation mechanism).
A self-signed certificate (of the type that Acrobat produces) can be used only for #1. It cannot be used for ##2 and 3. The latter two come only when a certificate (with private key) is issued by a reputable Certificate Authority which is trusted (like VeriSign, Symantec, etc.).

Digital Signature...what am I doing wrong?

I have a signature block on my form, I bring the form into Acrobat Pro and extend features on the form to allow readers to sign it, I then distribute the form. I email it, fill it out, click on the digital signature block, it asks for me to sign the document, save as comes up to save to the pdf, then a pop-up comes up and says"This form is in a data collection overflow. To send your data back to the workflow initiator, please click Submit to ensure your data will be collected correctly.", I click OK, Send Form box comes up with email address and the name of sender, (it says Attachment is the pdf file, hit send, and email comes up with an xml file of my pdf that has a blank "To" (assuming this needs to have my email in it so I receive it).......my point is.......I just want the "pdf" I sent them to have the signature imbedded in it when they send it back, if they close the email (the pop up) and not send it, they go back to the form and the digital signature is now in the pdf I originally sent them, which is what I want, I just don't want to explain that they need to ignore the email popup, hope it is not too confusing.
Thanks
Mike

Hi NMcneil123,
What do yo mean by "will not work"? Do the people who try to sign your PDF file receive errors? Please describe the exact issue so we can figure out where the problem lies.
I look forward to hearing back from you.

Sara

What is the use of Digital Signature in export release build for AIR applications

hi Freinds..
what is the use of digital signature identity when we release build?

Well obviously it is an Ant build.
It looks to just compile/build a web application into a war so you can deploy it where you want to.
You don't need to edit it every time you are making a new page. It should work for any generic struts web application laid out in the fashion it expects.

I forgot my digital signature. What do i do?

I forgot my digital signature. What do i do?

If you mean that you forgot the password for your digital ID, there's nothing you can do apart from remembering it. If this was a self-signed certificate that you created in Acrobat/Reader, you can make another.

Update on 10.6.8 fails due to digital signature on update is missing

wanting to install the Parallels version 10 and it won't work on 10.6.8 version of my Mac OS so I learned how to go to the software update which indicates an update is available. When I go ahead and load the update it runs fine and then stops with a message that the Macbook Pro EFI Firmware Update can't be saved. It says the digital signature on the update is missing or invalid.
I don't know if the digital signature is on my computer or the update? I would upgrade to a more recent version of the OS but don't know what will work.
Can anyone help?
Dan

Parallels 10 isn't compatible with 10.6 according to the web site.
Mac Requirements
Hardware:
A Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7, or Xeon processor (Core Solo and Core Duo processors are no longer supported)
Minimum 2 GB of memory (4 GB of memory is recommended to run Windows 7 in a virtual machine or if your host OS is Lion)
About 850 MB of disk space on the boot volume (Macintosh HD) for Parallels Desktop installation
About 15 GB of disk space for each virtual machine
Software:
OS X Yosemite 10.10 or later
OS X Mavericks 10.9.4 or later
Mac OS X Mountain Lion 10.8.5 or later
Mac OS X Lion 10.7.5 or later
Check that your computer is compatible with Mountain Lion/Mavericks/Yosemite.
To check the model number hold down the option/alt key, go to the Apple menu and select System Information.
MacBook (Late 2008 Aluminum, or Early 2009 or newer) model number 5,1 or higher
MacBook Pro (Mid/Late 2007 or newer) model number 3,1 or higher
Your Mac needs:
OS X v10.6.8 or OS X Lion already installed
2 GB or more of memory (More is better - 4 GB minimum seems to be the consensus)
8 GB or more of available space
Check to make sure your applications are compatible. PowerPC applications are no longer supported after 10.6.
Application Compatibility
Applications Compatibility (2)
Do a backup before installing.
If you can/do upgrade, I recommend you make a copy of the installer and move it out of your Applications folder. The installer self-destructs. The copy will keep you from having to download the installer again. You can make a bootable USB stick to install using this free program.

Making Multiple Digital Signatures Read-only in Form (Acrobat 9)

I have created a form which includes two (2) digital signature fields. What needs to occur with the form is Person1 fills the form and then digitally signs it thereby making the form fields read-only . Person2 then digitally signs the form which should make Person1's digital signature read-only.
Here's what I've done:
1) For the Person1 digital signature field, in Digital Signature Properties, under the Signed tab, I have selected Mark as read-only <all fields except these> and selected the Person2 digital signature field.
2) For the Person2 digital signature field, in Digital Signature Properties, under the Signed tab, I have selected Mark as read-only <all fields> since once Person2 signs the form I do not want Person1 to be able to clear the digital signature and make changes to the form.
Here's what actually occurs:
Step 1 above works fine. Once the signature is applied all the form fields are read-only except for the Person2 digital signature field.
The problem is that after Person2 digitally signs the form, even though I selected all fields as read-only, Person1 can 'clear' their signature which leaves all the form fields available for editing and leaves Person2's digital signature still on the form.
I honestly don't care about 'validating' signatures on this form since it's going to be printed but I cannot allow Person2's signature to remain on the form and allow Person1 to edit the form.

My computer will not let me download because it says there is no digital signature I need this for a college course how can i download it?

I am taking a web design class and my instructor wishes us all to use the same browser. She has provided a link in her syllabus and it does go to the download site for Firefox. However, as I am running the download my computer pops up with "there is no digital signature" and "this file is corrupt" and will not download it. What to do?

Make sure that you do not run the file directly, but save the file to the Desktop and start the installation via a double-click.<br />
You may need to unlock the file via the right-click context menu: Properties > Security

Temporarily disable Digital Signature Checks to Install MS SQL Server 2008 with no Internet Access

I am attempting to install a licensed copy of MS SQL Server 2008 in a Private Enclave that does NOT have Internet access on a Win2008 R2 SP1 server (that is VM - thus I can't reboot and press F8 to select "Disable Driver Signature Enforcement"
). The installation fails with an error of the vc_red.cab file being found either corrupt or a bad digital signature. The file is good, but the signature has an expiration of 2011. I understand that a DOTNET SDK v1.1 program called setreg.exe
will enable disabling the digital signature check, but I am not permitted to use that program.
I might be permitted to use the "Signtool.exe" utility, but it is not clear what command sequences are necessary to disable and then re-enable the Digital Signature checks.
I saw a thread that recommended using the command:
bcdedit.exe /set nointegritychecks ON
However, the comments indicated that this might not have worked.
Are there Registry settings I can use with regedit to make the necessary changes to be able to install the application? I anticipate running into this problem with other software when I do not have Internet connectivity. I already tried
downloading the Microsoft CRL files; updated the lists on the Server; and rebooted. This did not solve my problem.

Hi,
As far as I know, it is not recommended to disable digital signature check.
Since we are not familair with installing MS SQL server, please also refer to SQL forums below to see if experts there have more insights regarding the matter.

Excel 2013 crash - related to digital signature?

This is a cross-posting of a thread originally started in Microsoft Answers (Office- Excel) forum, advised to post in this forum by MS support engineer Mohan Suryanarayan (link to other forum: here).
I have a VB macro in file A (which otherwise contains only several Excel Tables with named ranges). My digital signature (for signing code) is attached to file A.
As the macro executes, the Open file dialog is called up so that the User can select a secondary file to open (file B or C).
Files B and C contain several sheets with formulas and Excel Tables, and also their own extensive VB macros. My digital signature is also attached to files B & C.
The remainder of the macro in file A simply executes an update of the Excel Tables in the secondary file, before saving & closing it.
I have been finding that during execution of the file A macro, Excel crashes and closes all open Excel files.
If I remove the digital signature from the secondary files then the macro in file A executes with no problem.
The macro was written in Excel 2007 and on a different laptop, with different digital signature, and used to have no problem at all. When a new laptop was purchased a new digital signature was obtained and placed into all of the files.
Execution of file A is a critical process - I need help with stopping the crash, while maintaining a digital signature in the secondary files (so that their own macros can execute).
Event Viewer error shows the following:
Faulting application name: EXCEL.EXE, version: 15.0.4667.1000, time stamp: 0x543d366c
Faulting module name: mso.dll, version: 0.0.0.0, time stamp: 0x5447696f

JL Latham replied:
Tom, all I can give you is relatively non-information. I haven't experienced that type of behavior even in Excel 2013 with digitally signed macros in multiple workbooks. But my digital signature is a commercial one from DigiCert, not
self-cert. I'm not even sure what piece of Excel or Office processes the digital signature (that is, whether it is mso.dll or not). But your whole process has more moving parts than most of mine involving multiple workbooks do - I quite often turn
off .EnableEvents when doing things like that just so event driven macros in the other workbook(s) do not execute.
Do the macros in the 'B files' have to execute during all of this processing in file A? If not, have you tried turning interrupts off:
Application.EnableEvents = False
before starting to work with the B-files? Maybe something in them, such as a Worksheet_Change() or other event triggered process is messing things up?
If you do use Application.EnableEvents=False, remember that you MUST re-enable that later in the code with Application.EnableEvents=True to get responses to things like button clicks, changes in a worksheet or other event driven processes
to run 'normally' again.
Have you looked at this discussion:
http://answers.microsoft.com/en-us/office/forum/office_2013_release-excel/excel-2013-crashing-immediately-when-attempting-to/ea2ab100-5525-4a0d-a3cf-6977319f954f
Sounds very similar to yours - original signature created in 2007, and crashing in 2013. Some suggestions were made, but whether they fixed the issue or not is unknown: OP never came back and said "fixed it" or "didn't fix it".
I replied:
In answer, the secondary B files don't execute any part of their macros during the A file process, and I hadn't included an EnableEvents = False within the file A code. However, I have just tried it to check if it made any difference and unfortunately it didn't.
I had read the thread you gave a link to before posting, and also the sub threads given within that one, but didn't see anything I thought of immediate parallel other than an Excel 2013 crash.
The way I read the linked thread was that a User added a signature in Excel 2007 and when they tried to open the file Excel (2007?) crashes, although other people using Excel 2013 can open it (not clear whether it means others can open the one with
the 2007 signature or without it).
Anyway, the differences in my situation are that:
(1) my B-files were originally created in Excel 2007 on a different laptop to current and had their own signature attached. I maintain a 'stock' of B-file versions, some of which have the old signature and some the new. If I run the A-file macro
on one of the B-files with the old signature then it executes ok;
(2) I am able to open the B-files ok, no matter whether the signature in them derives from the old laptop with Excel 2007 or the new laptop with Excel 2013;
(3) the macros within the B-files execute ok (this includes any versions of the B-files which still have an old signature attached, by removing the old signature and replacing with the new and executing on the new laptop);
(4) the offending operation which triggers the crash (when the B-files have the new signature attached) is a Resize of the Excel Tables within the B-file. I understand that I may eventually have to find a workaround for this operation but initially
I want to sort out the signature issue (I'm reasonably sure the signature issue is not a red herring where the Resize is the 'real' problem).
Regards, Tom

Hi,
According to your description, this issue occurred with some particular files that stored in SharePoint site. Did the user download the file to local disk to print?
Based on the event log >>Faulting module name: EXCEL.EXE<<, it does not show the root Faulting module. Thus, please try to follow this KB to do general troubleshooting:
https://support.microsoft.com/en-us/kb/2758592
Then, if you have used "printer status application", please go to Device settings -> Installable options -> Printer Status notification and select disable.
If this issue still exists, we may need to collect the App crash dump file:
https://technet.microsoft.com/en-us/sysinternals/dd996900.aspx
You can try to analyze dump by yourself if you would like to：
