Error inserting cryptographic services provider by signed applets

I want to create a signed applets that will insert cryptographic services provider to the system dynamically by the following code:
Security.insertProviderAt(new com.xxx.Provider(), 1);
// com.xxx.Provider is the provider class of a a 3rd party cryptographic services provider.
MessageDigest md = MessageDigest.getInstance("xxx", "SCL-Java");
// xxx is the provider string
md.update("dd".getBytes());
md.digest();
However, an exception occurs during the execution of the code:
MesageDigest md ......
Is there anyone meet this problem and solve it before?
Thank you very much
Dennis Chan

    I assume you are implying "biztax" application here, right?
    I have contacted their program lead, with no result at all.
    Past days I have been searching for a solution - reinstalls / new systems - no solution.
    This issue appeared a week or two ago only.
    I found http://forums.adobe.com/message/5338853 useful - but no positive results either.
    http://test.eid.belgium.be/faq/faq_nl.htm obviously didnt help either.
    If anyone finds a solution to this issue, please do let me know - any help is appreciated.
    Biztax tells to use the "signature", not the "authentication"  - but it is only Auth. that is showing up as option to sign (that works)
    ps, did you fiddle with the Adobe Reader XI security settings and import that PKI etc as well? I hoped that would be the breaktrough. Sadly i'm still crying in my chair.
    Oh, and dont forget: they claim nobody else got this issue. Maybe one or two people. (We got about 8 customers experiencing exactly the same symptoms at the same time )

    Navy Chief

    Hi Chief Mendenhall,
    It's really a Microsoft error, not a Acrobat error, but I know that doesn't make the inability to sign any less frustrating.  This probably has something to do with the communication bridge between Acrobat, Windows, and the CAC software. I know you're not responsible for software upgrades, but is there any chance you can download the free Adobe Reader (Adobe Reader Install for all versions). Even though Reader doesn't have the same editing capability as Acrobat Pro, it will allow you to sign a PDF file, and what I'm looking to see is if this is somehow related to the age of version 8.1, which is well past its end-of life. Even version 9 in longer supported.
    Thanks,
    Steve

  • CA Cryptographic service provider?

    Hello,
    I am planning to install Single tier Enterprise CA on a dedicated Windows 2008 R2 Server.
    We still have Windows XP SP3 workstations and I have some questions about the "cryptography" options on the Certificate Authority installation wizard.
    The "Select a cryptographic service provider (CSP)" -selection defaults to "rsa#microsoft software key storage provider". I'am not sure can I select it, or any of the "Cryptography Next Generation (CNG)"
    providers (marked with #).
    Does anyone have any information about which CSP I should select?
    I believe Windows 2003 CA Defaults to "Microsoft Strong Cryptographic Provider" so thinking of selecting that to guarantee compatibility with Windows XP.
    Any recommendations on "Key character lenght" and "Hash algorithm for signing certificates" are also very welcome.
    Thanks
    lakend

    You should use the strongest provider (which provides additional features) that is supported by the operating system that runs CA service. In your case it is Microsoft Key Storage Provider. Do not use any legacy provider (strong or enhanced CSP). With Microsoft
    KSP you have several options: xxx#Microsoft Key Storage Provider, where xxx -- is public key algorithm supported by the provider. Here you must select the algorithm that is supported by all certificates clients. Currently RSA is Internet PKI standard algorithm
    which is supported by almost all certificate clients.
    In other words, the most "safe" configuration is RSA#Microsoft Key Storage Provider, signature algorithm = "SHA1" and key length 2048. The following variations are possible without affecting many clients: change key length to 4096 (I don't see a big deal
    here) and change to SHA256 signature algorithm. However, legacy clients (Windows XP and Windows Server 2003) may not work with this algorithm (they require updates to support SHA2 algorithms).
    My weblog: http://en-us.sysadmins.lv
    PowerShell PKI Module: http://pspki.codeplex.com
    Check out new:
    PowerShell FCIV tool.
    Thanks Vadims for the solution and others for confirming.
    Installing ca with:
    CSP: Microsoft software key storage provider
    Key length:2048
    Hash algorithm for signing certificate: SHA1
    CNG public key algorithm: RSA

  • Windows Cryptographic Service Provider - error code: 2148532334 (Windows 8.1)

    Dear,
    since my computer was recently updated from Windows 8 to Windows 8.1 I have a problem with placing my signature (via certifcates).
    Before the update I could sign all my pdf-files with my electronic identity card - without issues.
    Now I receive a window: "windows-security" which says: Smartcarderror (some required programmes are not installed on the system).
    When I click "cancel" I get the error code in subject.
    Another card reader is not changing anything, neither another smartcard (id-card).
    Please advise, as signing pdf-files is very important for our company.
    Thanks. Willem Van Lommel
    NB: in my opinion all other updates are done without troubles.
    NB2: please find herewith some prt scns (in Dutch):
    1. before a smartcard was pushed in the cardreader:
    2. after the smartcard was added (same when card was added to other cardreader)
    3. because "ok" didn't result in anything -> you have to click "cancel - annuleren" or on the red X (at the right corner), then the result is:

    If by "Adboe X Pro" you mean Acrobat, you are more likely to get a useful reply if you ask in the Acrobat forum.
    All I can tell you that this error (0x80100068) means "The smart card has been reset, so any shared state information is invalid."

  • Error 2148073513 When Attempting To Digitally Sign In Acrobat 11 Standard

    I'm attempting to use Acrobat 11 Standard to digitally sign a PDF document with a 2048 bit certificate from our internal certificate authority, and I'm receiving the following error:
    Error encountered while signing:
    The Windows Cryptographic Service Provider reported an error:
    The requested operation is not supported.
    Error Code: 2148073513
    The operating system is Windows 7 Enterprise x64.  When I remove Acrobat 11 Standard and install Acrobat 9 Standard on the same Windows 7 system, I am able to successfully sign the document using the same certificate that was giving the error with 11.  Also we have been using Acrobat 9 on Windows XP with these same certificates for a long time and never encountered issues with digitally signing.
    Any ideas of what might be causing this issue? 
    Thanks in advance
    Josh

    Hi Josh,
    The error message comes from Windows (not Acrobat), but Acrobat 11 is probably asking Windows to do something that it can't. What it is I don't know because the error message is too vague. One thing we can do is to take Windows out of the picture and see if you can sign when Acrobat accesses the digital ID itself as opposed to asking Windows to do the work. This is a two step process, first, export the digital ID from Windows into a file, and then import the file into Acrobat (it's not really an import, but I'll leave it at that for now).
    Step 1 - Export the Digital ID
    Launch Acrobat
    Select the Edit > Preferences menu item
    Select Internet from the Categories list box
    Click the Internet Settings button
    Select the Content tab on the Internet Properties dialog
    Click the Certificates button
    Highlight your digital ID and then click the Export button
    Click the Next button on the Welcome panel of the Certificate Export Wizard
    Select the Yes, export the private key radio button, and then click the Next button. If this radio button is disabled you can stop here and let me know that the private key is not exportable
    Select the Include all certificates in the certification path if possible checkbox & the Export all extended properties checkbox and then click the Next button. Only select the top and bottom checkboxes, DO NOT delete the private key!
    Create passwords for the file and then click the Next button. You will need this password to sign with so make sure it is something you can remember.
    Pick a file name and location. Browse for a location you can remember as you will need to know where you put the file in order to use it to sign with. Click the Next button.
    Click the Finish button
    Click the OK button on the confirmation dialog
    Click the Close button on the Certificates dialog
    Click the OK button on the Internet Properties dialog
    Step 2 - Add the file to Acrobat
    Select Signatures from the Categories list box
    Click the More button in the Identities & Trusted Certificates group box
    Click the Add ID toolbar button
    Click the Next button
    Click the Browse button
    Navigate to and select the file you exported above and then click the Open button
    Enter the password you used above and then click the Next button
    Click the Finish button
    You will see two items in the list box with the same name. Highlight the one whose Storage Mechanism is "Digital ID File"
    Click the Usage Options toolbar button and then select Use for Signing
    Close the Digital ID and Trusted Certificate Settings
    Click the OK button on the Preferences dialog
    The next test is to see if you can sign a file. Please let me know if it works or not.
    Thanks,
    Steve

  • WebService call from signed applet and MS Vista

    Hi.
    I'M developing a system that needs to call web services from a signed applet.
    I have made the solution like this.
    The applet starts by checking that the 12 needed libs is present under the <java home>\lib\ext folder. if not it will download the files automatically and restart the browser.
    This works fine in Windows XP because the signed applet gives me read/write access to the whole machine, but in Vista this isn't possible anymore (as i understand it).
    My question: Is it possible to put these libs in another folder that the ext lib? I have tried to define the "archive" tag in my Object tag but i get the class not found exception thrown in my face.
    If there is a solution to this i would very much like some pointers!
    If not what can i do to get access to the <java home>\lib\ext folder under Vista?
    Regards
    Michael Pallesen

    When invokin applet methods via javascript, you are accessing privileged actions from an unsafe source.
    Depending on your needs, you could either load the system variables in applet init into class variables and return the information contained in the class variables to javascript or wrap the method calls inside AccessController.doPrivileged() calls.
