"Can't set up certs for trusted CA's" error

Hi,
I'm using JCE 1.2.1 for encryption. I have no problem running in current date (i.e. yr 2001) but
when I change the system date to a date less than the "last modified date" of the JCE jar files or to a date 5 years after this, I encountered this error.
any ideas?

I M getting the same error as following:
Exception in thread "main" java.lang.ExceptionInInitializerError: java.lang.SecurityException: Cannot
set up certs for trusted CAs
at javax.crypto.b.<clinit>([DashoPro-V1.2-120198])
at javax.crypto.Cipher.getInstance([DashoPro-V1.2-120198], Compiled Code)
at test.main(test.java, Compiled Code)
I have copied all four jar files in classpath.
but it is still not working.
please help urgently.
regards.

  • "Cannot set up certs for trusted CAs" and Tomcat

    I have succeeded in downloading/installing the JCE component and writing a small java program that ecrypts and decrypts text.
    Now that I've tried to integrate this code into a web application, I'm getting the following exception message:
    java.lang.ExceptionInInitializerError: java.lang.SecurityException: Cannot set up certs for trusted CAs: java.lang.SecurityException: Cannot locate policy and/or framework files for signer restraint check!
         at javax.crypto.SunJCE_b.<clinit>(DashoA6275)
         at javax.crypto.Cipher.a(DashoA6275)
         at javax.crypto.Cipher.getInstance(DashoA6275)
    I've copied the four JAR files into the web-inf/lib directory. I believe that I need to make changes to the appropriate policy file (which I assume is the catalina.policy file under the tomcat/conf folder) but this doesn't seem to make any difference.
    Can anybody help??
    Cheers,
    Ben
    PS - I DON'T want to copy the JARs into <java-home>\lib\ext

    i've been dealing w/ jdk1.3 and jce
    installation, configuration, and exceptions for a day
    now. i've recently upgraded to j2sdk1.4.1 and i have
    the same problems:
    java.lang.reflect.InvocationTargetException:
    java.lang.ExceptionInInitializerError:
    java.lang.SecurityException: Cannot set up certs for
    trusted CAs: java.lang.SecurityException: Cannot
    locate policy and/or framework files for signer
    restraint check!
    can you give me a little more detail around your
    explanation. in particular, i can get my encryption
    code to run as a command line app using the JDK alone.
    its once i try to run the code inside of tomcat that i
    get this exception.
    so far, i've tried putting all the .jars in my
    classpath, as well as web-inf/lib, as well as
    jre/lib/ext, as well as tomcat_home/common/lib and
    nothing works.
    could this still be a provider problem as you indicate
    and how does that explain the fact that it works with
    the JDK alone?Sun's JCE 1.2.2 and their JCE Provider doing a cross checking of the classes and their signatures. In JDK 1.4 that cross validation were removed, but JCE framework still checking the signature of the provider.
    You may also need to check which JRE you are using. On windows you have two of them by default: the one within JDK installation and the another one within "Programm Files". The last one is used by default if you didn't specify the path for java command.
    I've been using BouncyCastle JCE and their provider for a while. It works just fine in web-inf\lib directory under the JRE 1.3.1. They also have the signed jar for J2SE 1.4 that does not includes JCE framework.
    Note that you have to register your provider dynamically if you going to use it in the web application. You also have to make sure that your web app has enough rights for that (check the security properties if you are using security).
    BTW, which app container are you using?

    I got the exact same problem on my server yesterday (Aug 1st) after I restarted it. Apparently on July 28th 2005 the certificate that jce 1.2.1 crypto package uses expired. I was able to confirm this by setting the server clock back to before July 28th and everything worked fine. I updated to jce 1.2.2 (http://java.sun.com/security/index.jsp) and it resolved my problem.

    Hi,
    I got the solution for this. JCE 1.2.2 is supported on JDK 1.4.1 and JDK 1.4.2, but both of them have different unrestricted policy jars. I was able to solve the problem once I downloaded the unrestricted policy jars for JDK 1.4.2 (which is used by BEA 8.1 SP5) from the following URL : http://java.sun.com/j2se/1.4.2/download.html

    Why ?
    [email protected]

    Hi Sri,
    I am working on a similar problem. In fact, while I write a simple stand-alone program, everything works fine for me.
    As soon as I embed the very same class into my application, I also get the error you see. The major difference I see between my application and the stand-alone program is the class loading, which my application does via its specialized class loaders. However, I failed to catch the encryption code in my class loader between the call to
    SecretKeyFactory.getInstance("PBEWithMD5AndDES").generateSecret(k);
    and the error.
    You have any idea how to track the issue down?

    Jack

    I haven't messed with 1.3 versions, but in 1.4.2 and later, the jce jar files have to be in <jre>/lib/security rather than in the classpath.

    Is there any way arround this problem???A few questions for you:
    (1) Have you updated the java.security file to include the SunJCE security provider i.e. :
    <JAVA_HOME>/jre/lib/security/java.security
    a line should be added into this file as such:
    security.provider.n=com.sun.crypto.provider.SunJCE
    , where n is the the order of which the security providers to be installed.
    (2) You should have all the necessary .jar files for the JCE packages and it should located in this directory:
    <JAVA_HOME>/jre/lib/ext
    Some developers make the mistake of copying the .jar files into the <JAVA_HOME>/lib directory.

    Is there any way arround this problem???A few questions for you:
    (1) Have you updated the java.security file to include the SunJCE security provider i.e. :
    <JAVA_HOME>/jre/lib/security/java.security
    a line should be added into this file as such:
    security.provider.n=com.sun.crypto.provider.SunJCE
    , where n is the the order of which the security providers to be installed.
    (2) You should have all the necessary .jar files for the JCE packages and it should located in this directory:
    <JAVA_HOME>/jre/lib/ext
    Some developers make the mistake of copying the .jar files into the <JAVA_HOME>/lib directory.
    HTH.

  • Can you set an alert for birthdays in Addressbook and iCal?

    When I migrated from Palm Calendar to iCal, my calendar had my birthdays in it repeating each year and with a 7 day alert so I could send a card or get a present in time.
    I see you can list a birthday in Addressbook and set the iCal pref to show them which is at first glance very cool and green but when I open the birthday event in iCal I don't see any way to set an alert which is a big limitation.
    If I can't set alerts, then the Addressbook/iCal birthday syncing is kind of pointless and limited, unless I'm missing how to set alerts.

    Hi Steven,
    This is one of the reasons why I wrote Dates to iCal.
    As well as automatically syncing birthday dates from Address Book, Dates to iCal can sync anniversary and custom dates. It can set up to five alarms for each date in iCal and can also set different alarms for birthdays and anniversaries.
    Best wishes

  • How can I set a password for firefox so that everyone have to enter the password before executing firefox

    My younger sister executed my firefox just at this afternoon(she originally use IE), and she saw something that can't be seen. How can I set a password for firefox so that everyone have to enter the password before executing firefox?

    Also see this for an English version of Profile Password:
    *Profile Password: http://nic-nac-project.de/~kaosmos/profilepassword-en.html#PPF
    It is an extension to protect the profile with a password, but being an extension that protection can easily be bypassed by starting Firefox in [[Safe mode]].<br />
    So do not rely on it.<br />
    If you want to protect content then you have to use methods supported by the OS like a separate user account with a password or an encrypted file system.

  • How can i set a layout for MIGO screen

    Hello all,
    How can i set a layout for MIGO screen. & make that layout default. Like i want to drag Requistioner column next to quantity in MIgo screen. temporarily I can drag but is there a way to save as layout & save it.

    Hi
    First you arrange however you want and then go to table settings which is there in the right corner of the item details and create a variant and save.
    Find a button with blue yellow and white at the top end above the vertical drag bar when put the cursor it will show you as Configuration.
    After creating the variant tick the check box use as standard setting below the variant
    Hope it helps

  • How can I set a default for webpages to expand to full screen?

    How can I set a default for webpages to expand to full screen? Every webpage I go to does not expand to a full screen which causes me to have to ctrl+++ each time. How can I set my preference to expand to full screen automatically?
    Thanks.

    The Firefox [https://support.mozilla.com/en-US/kb/Page+Zoom Page Zoom] feature does a domain by domain level of saving the users preferred zoom level settings, there is no default Page Zoom level setting in Firefox, as with some other browsers.
    Try the Default FullZoom Level extension: <br />
    https://addons.mozilla.org/en-US/firefox/addon/6965
    Or the NoSquint extension: <br />
