Installing the Unrestricted Policy Files and BC provider

mahdy_m_s · July 2nd, 2011, 01:14 AM

hi . as it is said in the book i download the Unrestricted Policy Files and add them in ext folder in both jdk and jre . but still i have this exception while running the SimplePolicyTest Code .

Code:

Exception in thread "main" java.security.InvalidKeyException: Illegal key size or default parameters
        at javax.crypto.Cipher.a(DashoA13*..)
        at javax.crypto.Cipher.init(DashoA13*..)
        at javax.crypto.Cipher.init(DashoA13*..)
        at Chapter1.SimplePolicyProject.main(SimplePolicyProject.java:39)
Java Result: 1

what can be wrong ?

by the way according to the book content i tried to install the BC provider but it was another failed attempt ..
is there any relationship between this two issues ?

Actually it says on page 5 "install the two JAR files it contains according to the instructions in the README file contained in the ZIP file." If you do that you should be fine.

yeah , but still i can not deal properly with the BC provider . i download the bcprov-jdk16-146.jar and copy this in all jre/lib/ext i have . i changed the java.security files to . is there any thing i should do more than this ?

Can you tell me a bit more about the problem? If it's a case of it not finding the provider you need to check your path so you can be certain you are installing it in the ext directory of the JVM you are using.

almost all of the jre/lib/ext folders in my hard has the bcprov-jdk16-146.jar and security.provider.N=org.bouncycastle.jce.provider. BouncyCastleProvider
is added correctly(with appropriate N) at the bottom of the list of all java.security files exist in my hard .
i can see the libraries added to jdk from inside my IED(netbeans 6.9) but still i take the message "the BC provider not installed " from out Put.
it is possible that i didnot find the correct path? what else can be the problem?

That's pretty much all it can be. You could also get the class loader confused (in some circumstances) if the jar is appearing in your class path twice.

If you're running on Windows keep in mind that a JDK install will install two JVMs. You'll need to make sure they are both updated.
