i dont know for unix but do this for win
Hi
I assume you use j2sdk1.4.2-02
You should first download change the policy of the JCE
By downloading this
http://java.sun.com/j2se/1.4.2/download.html
just JCE a and unzip in a folder read the read me doc so u should cut that 2 file and put here
C:\j2sdk1.4.2_02\jre\lib\security
and here
C:\Program Files\Java\j2re1.4.2_02\lib\security
done this then download the bouncy jar file from
http://www.bouncycastle.org/latest_releases.html
take the bcprov-jdk14-120.jar and put in following directories
C:\j2sdk1.4.2_02\jre\lib\ext
C:\Program Files\Java\j2re1.4.2_02\lib\ext
then u need to change the environment variable so in
the following directories open "java.security" in both
C:\j2sdk1.4.2_02\jre\lib\security
C:\Program Files\Java\j2re1.4.2_02\lib\security
and edit it and add the extra line
security.provider.6=org.bouncycastle.jce.provider.BouncyCastleProvider
save it done this
to see whether its install or not
try do run this program
import java.security.Provider;
import java.security.Security;
import java.util.Set;
import java.util.Iterator;
public class ProviderInformation {
public static void main(String[] args) {
Provider[] providers = Security.getProviders();
for (int i = 0; i < providers.length; i++) {
Provider provider = providers;
System.out.println("Provider name: " + provider.getName());
System.out.println("Provider information: " + provider.getInfo());
System.out.println("Provider version: " + provider.getVersion());
Set entries = provider.entrySet();
Iterator iterator = entries.iterator();
while (iterator.hasNext()) {
System.out.println("Property entry: " + iterator.next());
u should have some result that show I just cut part of the out put so u can get full out put
