Digitally Signing Media Breaks projector

Hi All,
Digitally signing a projector exe, apperas to corrupt it.
Before siging it all works fine, afterwards it brings up the
message:
Unable to Load Movie Playlist. Does the .ini file exist? it
must contain a section [Movies] with an entyr movie01=Pathname.dir
We are using MX2004 and there appears to be no option to
generate an ini file, and before running the digital signing
program no ini file is required.
Is there a known fix for this issue?
thanks in avdvance

We can't do that unfortunately. The problem is that our
projector is executed on Autorun and then we launch setup.exe from
this. Thus although we've signed setup, the msi and the cab the
projector is executed before it gets to them.

Digital signature for flash projectors

I have a client that would like me to digital sign my flash projector on windows and on a mac.
Is there anyway to do this? I haven't found any resources outside of a workflow for AIR development.
any help is appreciated! Thanks!

Update 9.1.2 breaks digital signing documents in Adobe 9 Pro on Windows XP

I am able to digitally sign documents using an Aladdin eToken Pro 64k with a fresh copy of Adobe 9 Pro for Windows. However when I update to version 9.1.2 digital signing fails with an "error encountered while BER decoding". Signing still works on Vista and Adobe 9.1.2 Pro. I've checked to make sure none of the settings relating to digital signing changed during the update and none have. Anyone have any ideas on how to correct the problem?

Hi Nick,
First up, there was a small error in my previous post. I said the version of Acrobat (and whenever I say Acrobat I really mean both Acrobat and Reader, but I'm too lazy to type both) that was modified to fix the bug in SHA-1 fallback was 9.1.3, but I really meant 9.3. Sorry about that.
I saw your post from yesterday (http://forums.adobe.com/thread/563601) where you broached the BER decoding error, but in the post above you said signature creation isn't failing any more, so hopefully some update has fixed the problem.
Here's a little bit about the BER Decoding error. During the signing process Acrobat writes the entire file to disk (which is why you always get the Save As dialog as part of the signing process) in the signed state with everything but the actual signature. However, it does leave a hole in the file where the BER encoded cryptographic data will reside once it's be computed and formatted. One thing that is created before the actual signature is the signature appearance. The signature appearance in the form field isn't really the signature proper, but just a graphic representation of the actual signature. The reason that the signature appearance is written to disk before the signature is created is because it too is part of the signed data and must exist before the actual signature is created.
In a perfect world, after the file is written to disk, the cryptographic signature is created and written into the hole in the PDF file, and the signing process completes without any problem. However, if we get to the point that the file has been written out, but during the actual signature creation the process fails, that hole I mentioned isn't filled in. It's not really a hole per se, but a block of zeros that act as a placeholder for the BER encoded data. Because there was some sort of failure and Acrobat didn't get the signed data back from the hardware device what you end up with is a PDF file with a signature appearance, but no real signature in the file. When you click on the signature field Acrobat tries to validate the actual signature, it finds the block of zeros where the signed data was supposed to be, it tries to decode the zeros and gets (as you might well imagine) nothing back and displays the BER Decoding error.
Let leaves us with why didn't Acrobat get the signed data back. When using hardware devices, such as tokens or smart cards, the actual cryptographic signing (the encryption of of the digest with the users private key) takes place on the device. Acrobat (nor any other application) doesn't have access to the private key, which is what makes hardware devices more secure. It's up to the device to sign the data and send it back. If there is any kind of breakdown in that communication channel (which I mentioned in my previous post) the signature creation doesn't reach fruition and you're left with an unsigned file that looks like it was signed because there is a signature appearance.
This is a case where we are providing technically correct, and utterly useless information. It's true that we can't decode a bunch of zeros, but what we should be telling the user is there is no signature (it's kind of like the Matrix where there is no spoon ).
I hope this helps explain what you're seeing. If the the signing process breaks down again please make sure you are using the latest version of Acrobat/Reader and the token software is up-to-date. If everything is current and the problem returns please let me know.

How do I digitally sign projector files?

I am currently selling apps in Flash projector .exe format. How can I install a certificate from Verisign or Thawte?
Roger

I want to access the file system of the client using a
servlet which shall be digitally signed.
You cannot do this. It is technically impossible. You are referring to an Applet. There are two ways to get the Applet to read the files of the client system.
1. Have the client open up security by editing the java.policy file, which is dangerous.
2. Digitally Sign the Applet.
How do I do it.Please send the code.
Write the code yourself. Sorry to say, but nobody here is going to program your code for you. That is, unless you pay them money!

In Acrobat XI, how can we have more than 2 people digitally sign a document or template?.

The document is a PDF template with 2 signature fields for approval. When the first person digital signs the document it shows the GREEN tick that it's signed and all signatures are valid. Then it gets emailed for the second person to digitally sign and ofcourse, the document becomes invalid. (We don't want to use the echoSign cloud service and there is no Acrobat server setup). Can someone share the light please?

A PDF Form Template will try an execute an action to create a new page based on the template page. This action will break the first signature because it changes the document by adding a new page after it has been signed. Is it imperative that the document be a PDF Form Template? If all that is called for is two signatures then create the document with two signature fields and without it being a PDF Form Template.

Making a subform appear when Digitally Signed

Hi,
how would i get a hidden subform to appear when the pdf is digitally signed, what i need to appear is:
form1.page1.subform6.SubmitForm.presence = "visable";
form1.page1.subform6.presence = "visable";

You would have to run your code on the preSign event otherwise if the form changes after the signature is applied it will break the signature. Your code is OK except that it is visible not visable.

Digitally signed JWS client - invoking email program on the client

Hi All,
We have a digitally signed JWS application (non-sandboxed), I would like
to programatically invoke the email client outlook etc, with attached log file ( of our app)
basically an error handling mechanism such that any error on the client side can
be sent to the dev team by simply clicking a button say "Send Log File" on the application
Which should utimately opens end user's email client with attached log file, and users sends it to us from the email
Appreciate any pointers/tutorials in this regard
Many thanks,

Many thanks for the reply, Our applications are targetted 1.5 and before appreciate if you could clarify the following
appreciate if you could clarify
- forms an output stream direct back to a report page on the server, and prepares to write the entire report to that stream - logs, screenshots, system settings, ..the time, + you might prompt the user for a 'reason?', whatever.. back to the reporting page. - after writing the stream to the server, the server returns an URL in the output. by the time user has encountered the error it means, the exception logs are already written, now is this you have this in the memory and on user action write to the servlet outputstream ? , bit confused here is it whether normal IO operation to read the physical log files and write to servlet output stream ? ( i believe is the case on a successful operation, the log file just writes to disk )
In the back of my mind, I was thinking of the 'sandboxed' version I am developing, but strictly speaking, no.
The way I am using logging is this.
I create a custom handler that stores the last 500 (configurable) logged messages, then add that to an anonymous logger, which is used for all logging operations.
The logs might be written out somewhere, but my app. no longer cares either way. If a problem occurs, they (without any further elevation of privileges) have easy access to the last 500 logged messages.
Now, I'll break from what my sandboxed app. does here (too long, not relevant) and cut to..
If that were the case in your app., it would take no further reading of files on the local disk, in order to submit the report back to the servlet. We could form the entire log as a String within the app., then stamp it out to a ByteArrayOutputStream, and take it from there.
That does not make much sense for an all-permissions app. such as yours. It is more efficient to allow the logs to be written to disk as per normal, and only open (& submit) them if needed. Using a 'cycling' log name, you might also even offer the ability to submit the logs of earlier run(s). Remembering the logs of earlier runs is not a viable option for my sandboxed app.

So (..shrugs) use .NET? Is this application only run on Windows? Does .NET support every platform you want to deploy on?
If this app. is only targeted at/supported on platforms for which .NET does the job, perhaps it should be considered as an alternative. I do not think it is necessary though (and I doubt it would work on my Windows machine).

HP EliteBook drivers not digitally signed

Hi,
Big problem here - I have upgraded a new HP Elitebook 840G1 from Win8.1 to our companies Enterprise Win7 x64 image.
When trying to install some of the drivers from the Official HP Support page for this model I am getting Programme Compatibilty errors saying the drivers are not digitally signed and I should uninstall them.
In particular I recieved this error after installing HP 3D driveguard. I uninstalled the program but it appears to have left the disc driver behind as when the laptop is now booted up it goes into system recovery mode. The only way I can get it to boot is to F8 and select to disable driver signature enforcement... NIce one HP!!
The IDT PC audio driver also throws up an error saying it is not digitally signed although the PCI REaltek media driver did go in OK.
Anyone with any ideas of how to fix the broken 3D drivegaurd issue??
I cant beleive that HP are offering up drivers that are not properly digitally signed....

If that unit doesn't come with 8.1 support asking for help on unsupported O/S will not get forum user help here. Want User forum help here you need to go back to the supported O/S then others can help you. You don't install unsupported O/S and expect to get support.....HP will also tell you that as well.

NVIDEA outputs digital signal to LCD projector

We are having a different problem with connecting to LCD projectors at our school. The problem seems to result from a Crestron media manager between the MBP and the projector. the MBP connects via the DVI-to-VGA adaptor. If the MBP has the NVIDIA GeForce 8600M GT card, it sends a digital signal to the projector and nothing shows up on the screen. Displays preference panel shows the 2nd monitor as "Digital 170T." There are 3 MBPs showing this behavior. one older MBP with an ATI Radeon X1600 card connects just fine. My G4 with an ATI Mobility Radeon 9700 also worked (for over 3 years). both show a "VGA" connection in Displays preference panel.
The NVIDIA MBPs can connect directly to an LCD projector and output a VGA signal that works. it seems that the intermediate Crestron system is not sending a signal that the NVIDIA requires to know it is connected to a VGA display. and of course, Crestron is telling our support people it is not their problem; NVIDEA's web support doesn't even touch Mac topics.
So how do we convince the NVIDIA card to output a VGA signal from the DVI port?

Nvidia Control Panel. Change the video output. Should work.

How to Digitally sign a PDF report/Mail automatically?

Hi experts!
I have cron'ed shell script that runs a report (Oracle Reports 6i) and the output the report is a PDF document which i send it as an attachment to a mail recipient on my MS. Exchange server.
This is working fine!
Now, i wish to digitally sign either the message or the PDF document it with a Digital Certificate (from Verisign).
Can you please guide me on how this can be done? Should I do it at the Database level, Application server level or the OS level (sendmail)
[Assume i already have already received my certificate from Verisign]
Thank you in advance for your precious time and replies.
Best Regards

I suspect you may have a corrupt photo or image that is causing the sync to fail or quit. You might want to try removing all of your photos by deselecting them in iTunes then sync - and try adding them by each sub-folders until you are able to nail down which sub-folder of photos, that causes the sync to stop or gives you errors.

Email cannot be read when it is only digitally signed

I, and my boss (using a Curve) have been having continuous trouble with reading emails that have been digitally signed. Now, before people start running down the basics, here's what I have done so far:
1. Installed latest ROM for both devices, still waiting on 4.5 for my 8830...
2. Installed S/MIME application on both devices
3. Installed latest Desktop OS on both machines and synchronized certificates from desktop to device and back
Here is the systems we are using:
1. Exchange 2003
2. BlackBerry Enterprise Server (version unknown, not my department)
3. Verisign certificates, managed on-site
Here are some of the caveats we are experiencing.
1. We can read signed and/or encrypted messages from Outlook (03/07), Entourage (04/08), and Thunderbird problem-free
2. We can read signed AND encrypted, or encrypted ONLY, messages from Mulberry, but we cannot read signed ONLY messages from Mulberry
There is no error message, in fact everything "looks" normal, we are just unable to view the body of the emails. What we do see is similar to this:
Received Using: <mailbox> (S/MIME)
Message Status: Opened
To: <me>
Sent: <date>
From: <Mulberry User>
Subject: <subject>
<img><img> Trusted
[1 Attachment]
application: Unknown (2K)
The <Mulberry User> did some research and sent me the following information:
This is a signed message sent from Outlook:
MIME-Version: 1.0
Content-Type: multipart/signed;
        boundary="----=_NextPart_000_00CE_01C99022.D841F9A0";
        protocol="application/x-pkcs7-signature";
        micalg=SHA1
This is a signed message sent from Mulberry:
MIME-Version: 1.0
Content-Type: multipart/signed; micalg=sha1;
protocol="application/pkcs7-signature";
boundary="==========45CF5864B8BBBF80D9D4=========="
See any difference between those two?
According to the RFC, the "application/x-pkcs7-signature" MIME type is supposed to be handled, by clients, the same as the "application/pkcs7-signature" MIME type, which is the "correct" MIME type. So Mulberry handles it correctly. Outlook does not. And neither does the Blackberry. Because *all* clients *should* honor both types.
http://www.ietf.org/proceedings/05nov/RFCs/rfc2311.txt
"C.1 Early MIME Types
Some early implementations of S/MIME agents used the following MIME types:
   application/x-pkcs7-mime
   application/x-pkcs7-signature
   application/x-pkcs10
In each case, the "x-" subtypes correspond to the subtypes described in this document without the "x-"."
"This memo also discusses how to use the multipart/signed MIME type defined in [MIME-SECURE] to transport S/MIME signed messages. This memo also defines the application/pkcs7-signature MIME type, which is also used to transport S/MIME signed messages. This specification is compatible with PKCS #7 in that it uses the data types defined by PKCS #7."
3.4.1 Choosing a Format for Signed-only Messages
There are no hard-and-fast rules when a particular signed-only format should be chosen because it depends on the capabilities of all the receivers and the relative importance of receivers with S/MIME facilities being able to verify the signature versus the importance of receivers without S/MIME software being able to view the message.
Messages signed using the multipart/signed format can always be viewed by the receiver whether they have S/MIME software or not. They can also be viewed whether they are using a MIME-native user agent or they have messages translated by a gateway. In this context, "be viewed" means the ability to process the message essentially as if it were not a signed message, including any other MIME structure the message might have."
This means that the Blackberry is required, by RFC, to be able to read a signed message even without the aid of S/MIME capable software. The fact that it does not is a failure of the Blackberry.
The above email was in reference to the fact that all of these emails that cannot be read on the devices, can be read in Outlook, and when a signed message is sent from Outlook, it can be read on the devices. Furthermore, this is not to say that the information above is 100% valid and correct, but I am hoping that it sparks some discussion and hopefully a resolution can be found.
Thanks for your time in reading this.

Well not 100% sure but in my experience the following setting is the problem "Enable S/MIME Encryption on Signed or Weakly encrypted messages". This setting is a per server setting and is found in the general options of the server.
When this is set to true the BES encryptes the message again over the signed message...but then for some reason unknown it doesn't decrypt it back when the client reads it.
Maybe you could ask your admins and try it out and see if it works...

Unable to digitally sign and save a PDF document

I am currently using ADOBE ACROBAT 8.0 Professional (Ver 8.1.0). I provide proofreading service for a client. The client provides me with a PDF which I use the comment and mark up tool to indicate required changes. Once all of the comments are complete, I mark the document approved or disapproved and attach a digital signature.
Recently, many files that I have recieved from the client will not allow me to sign and save the PDF. I can save the PDF without the signature but not when it is digitally signed. The error reads:
"The document could not be saved. A number is out of range"
I queried my client to find out if they have made any changes. They have recently upgraded to Illustrator 4 and they create the PDF's for me from the Illustrator files they work from. There are four teams using the same Illustrator program but not all of them are producing files that I cannot sign and save.
Can anyone tell me what the error indicates? Is there a property assigned to the document that I can not recognize that refers to this problem.
Since the files I work on contain proprietary information, I prefer not to attach them to this forum. If anyone is interested in helping, I will share a file to fully explain my problem.

I will try that, thank you.

Can no longer digitally sign PDF's with Adobe Reader 9

On our government network some of us have been upgraded to Adobe Reader 9 but now we can no longer digitally sign some PDF files.
People with Adobe Reader or Pro 8 can. Here is a link to one of the documents:
www.unl.edu/nrotc/Nc3065.pdf
I'm also attaching the document.
The document security shows as "Digital signing allowed" in Adobe Reader 8 but "Not allowed" in Adobe Reader 9.
Is there something wrong with Adobe Reader 9 or something we need to change?
Any constructive advice would be appreciated.

I cannot say for sure, but some of the technology the government uses (like the IRS) uses older technology that is no longer support in version 9. For example the IRS tax forms cannot be fillied in and saved using Reader 9. My bet your seeing a similar problem. There is no workaround. You will need to go back to Reader 8 or get Acrobat 9 Pro or Standard.

How to export HD files and play them on Western Digital HD Media PLayer?

Hi Folks,
I'd need your help here. I shoot HD video in AVCHD with Canon HF200.
My goal is to be able to export my edited footage with minimum quality loss and be able to play it on the well known Western Digital HD Media Player:
http://www.wdc.com/en/products/Products.asp?DriveID=735
The player supports the following formats for video:
Video - AVI (Xvid, AVC, MPEG1/2/4), MPG/MPEG, VOB, MKV (h.264, x.264, AVC, MPEG1/2/4, VC-1), TS/TP/M2T (MPEG1/2/4, AVC, VC-1), MP4/MOV (MPEG4, h.264), M2TS, WMV9
Here is what I do:
1. I convert the avchd files into .avi using Cineform Prospect HD.
2. Then I import and edit the footage in Adobe Premiere Pro CS3
3. Finally I export the edited footage using the ' BD-h.264 ' codec in the 'Adobe Media Encoder'
4. I end up with two files after the export: .M4V file (video) and .WAV file (sound).
The WD HD Media Player plays 'black' screen while displaying a message 'no audio'.
I guess the exported file is not fully supported by the WD player,
Any ideas? How can I combine the two files into one and play it on the WD player?
Maybe I'm not exporting it correctly?
Please share your experience and help me out.
Thanks

Let me give you an optimum example of my last HD to DVD timing. The video was shot with two cameras under good lighting conditions and there was very little color correction required and only a few special effects. The finished video was 39 minutes (1.35 GB). The AME encoding time on my 8 core (2.33 GHz) with a really fast RAID 0 array was 36 minutes 48 seconds! If you start adding in a lot of color correction and lots of other effects encoding time does increase significantly. I am convinced that the DVD was of much better quality that had we shot it in SD. I have had problem shoots (lighting) that required vast amount of color correction etc. that required many hours of MPEG2 DVD encoding.
Incidentlly I do not export from Premiere (which uses the new copy of the Project on your C:drive), I close Premiere and open AME and use the much faster true project file on my RAID 0 array.
