Acrobat/Reader and SRDP (digital signature)

I have read the document as James King Adobe published and made configurations to make Acrobat compatible SRDP. However when I sign a document and inspect the package generated CMS within the PDF file, the value of signature in Signed attribute certificate is not present. So I guess the signature isn't always consistent SRDP-BES. Is there anything I can do for Acrobat put a signature SRDP-BES?

Also, I have to check, I did a test. I took out a PDF with a CMS package that has the signature certificate signed attribute. The signature has been validated in Acrobat. After that, I intentionally put a random value as the signing certificate. When I open this PDF, it still valid fine in Acrobat. Therefore, I understand that Acrobat does full validation SRDP-BES. Is this good? It is a configuration which can make Acrobat do a full validation of the SRDP?

I use 9.1.3 version of Acrobat on Windows.

Thanks in advance

Hello

You are right that the /subFilter entry is required for part 3 of the specification of the SRDP. Currently, Acrobat supports parts 2 and 4 only.

    What is the difference between DC of Acrobat Reader and Acrobat Standard DC? I'm looking for the function to extract pages of large documents.

    Acrobat Reader is just a viewer/reader PDF; It cannot modify or create PDFs.

    You will need Acrobat Standard or Pro to extract pages from a PDF.

    Hi Patrick,

    A blank window appears generally if the Akamai detects that your computer does not meet the minimum system requirements to run the DLM.

    In most cases the JRE or ActiveX controls are not enabled.

    Try to switch to another browser to access your download, or you can download it from: http://get.adobe.com/reader/enterprise/

  • I have a DC account acrobat reader and cannot edit documents

    I have an acrobat reader DC account and I pay for a subscription that allows me to make a few changes of base and my desktop, everything works fine, but when I connect from my laptop (both computers running windows pc 10) he wants me to sign up for a service to allow me to edit the document When I click the button change.  I thought I could go in and use my account from any device?  Any help?

    Hi Gary,.

    You have creative cloud unique subscription App for Acrobat DC. You will be able to activate a single Acrobat DC device at any given time.

    However, you can use the Acrobat online services using Acrobat Reader DC approx. on other devices too, using you can use features such as comment on a PDF document, adding text, PDF export, send for signature, combine pdf etc..

    Just make sure that you are connected using the adobe ID with which you have the subscription for Acrobat DC.

    However, editing function only works with the principal of the Acrobat Pro DC not with Acrobat Reader DC application.

  • JDE 4.5 generates the debug file and require digital signatures for her

    I use 4.5 JDE

    I have my application and running upward, it requires digital signatures to BB because of the protected API.

    When I asked the digital signature, the digital signature only for my program listed JDE.

    Suddenly, the JDE produces a file of parallel debugging and also requires the signature of BB for this file.  I explain:

    My name is theprog.java.

    When I build the project the JDE generates the file theprog-1.

    When I ask digital signatures, JDE lists it will seek signatures digital for theprog and theprog-1

    How can I configure the JDE to request only the signatures of file theprog?

    Thank you.

    The BB JVM supports only the files of cod with a maximum of 64K code and data of 64 KB. Whenever a program becomes too large, the compiler will divide the program into multiple cod files, like myprogram - 1.cod, myprogram.cod, etc., myprogram - 2.cod.

    Each of them must be signed. It's normal.

    When the compilation is complete, the cod files are combined into a single .cod file that is actually a zip containing individual .cod files.

  • I upgraded to Acrobat Reader and Acrobat is no longer default player.

    Using Windows 7
    I recently updated my Acrobat Reader. Now Acrobat is no longer default PDF reader. None is in the default list of Control Panel.
    How to fix this.

    Thank you very much

    Robin Chapple

    Right click on a PDF file and select Acrobat to open with, select by default here. You really should not have installed Adobe Reader also because of these problems. Make sure that you select AR for not having a part remain memory resident to accelerate the opening - it will open instead of Acrobat in this case. By them, there has been no Acrobat Reader from version 5. The name was changed to put an end to the confusion.

  • How to use Acrobat JavaScript to perform digital signature (e-sign) in several PDF documents?

    With this script, I can perform the signature batch:

    Choose the Manager

    var manipulador = security.getHandler ("Adobe.PPKLite");

    Login - change as the case

    manipulador. Login ("test123", "/ D/Users/p004826/AppData/Roaming/Adobe/Acrobat/10.0/Security/Israel.pfx");

    information

    myInfo var = {password: 'test123',}

    Reason: "como Salvar tests."

    {CDM: 'defaultAndComments'};

    Invisible sign

    this.certifyInvisibleSign({)

    oSig:manipulador,

    oInfo:myInfo,

    cDIPath:"/c/temp/sigSign.pdf,"

    cLegalAttest: "Certificado ussando o JavaScript."

    bUI:false

    });

    But he accomplished only with a. File saved locally PFX. I am trying to find a way that allows the user to insert a card and enter a password for the electronic signature. Anyone know anything else?

    Sorry for my bad English

    Thank you!!!

    Finally, I managed to solve. As a result...

    / * Sign documents requesting the password/PIN * /.

    / * Israel * /.

    If you want to see the result, uncomment

    Console.Show ();

    Console.println ("Start");

    Starts the Security Manager and connects.

    var vPPKLiteHandler = security.getHandler (security. (PPKLiteHandler, true);

    vPPKLiteHandler.login({bUI:true});)

    Console.println ("Logged: isLoggedIn =" + vPPKLiteHandler.isLoggedIn);

    Event.RC = vPPKLiteHandler.isLoggedIn;

    If (! event.rc) {}

    App.Alert ("Login failed for signature - Signature in batch abandoned.");

    throw "Login failed" ;}

    signs the document, the routine certifyInvisibleSign already registered

    Event.RC = this.certifyInvisibleSign (vPPKLiteHandler);

    Console.println ("assinatura da Resultado:" + event.rc);

    If (! event.rc) {}

    App.Alert ("doesn't have the signing of the document" + this.documentFileName)

    +"- Signature in abandoned lot. ») ;

    throw 'Fail to sign' ;}

    Note: This action is possible by opening Acrobat X. After execution, you can select the PDF file or select the directory that contains the PDF files.

  • What can I do? I just change a pdf file, after you finish and save the changes, the stroke of the Acrobat Reader and lost all my changes, how do I get back them, he had a lot of work.

    What should I do toget back the changes that I made a PDF doc because Acrobat just stops?

    Hey Woisix,

    The auto save feature prevents changes to PDF since be lost after an unexpected interruption.

    Open the file to which you were changes. When you are prompted, click Yes to open the automatically saved files.

    If auto-save is turned off, then restart of the Preferences dialog box.

    Open Edit > Preferences > Documents and check "automatically save document changes to temporary file every XX minutes" and specify minutes for how often you want to save changes to the PDF files.

    If this feature has been disabled, so it is not possible to recover lost in the PDF file changes.

    Kind regards

  • Need to re - register a completed form on in Acrobat Reader and keep the same file name.

    I did collect a form developed for our client in. They need to access and save it several times without making several versions.

    Now that they can open, fill out some fields and "save under" a different file name. They must then go back and edit or add additional information to train at a later date.

    He won't let not the re - save the file with the same file name, only "save under". It is not very practical because they will end up with many versions of the same shape and all earlier versions would be obsolete and useless for them.

    You must disable the preview in Windows Explorer or close Windows Explorer.
