Which version of JDK are u using? Sun's JDK comes along with the KeyPairGenerator in the form of sunrsasign.jar in the jre/lib directory.
The IBM's jdk doesn't come along with the RSA provider so u have to put the sunrsasign.jar in the jre/lib/ext directory and edit the java.security file to include that security.provider.3=com.sun.rsajca.Provider Hope that helps Cheers Sachin -- To unsubscribe: <mailto:[EMAIL PROTECTED]> For additional commands: <mailto:[EMAIL PROTECTED]> Troubles with the list: <mailto:[EMAIL PROTECTED]>
