I am trying to initialize a Mac instance using an empty key. But it is failing with "InvalidKeyException".
Following is the snippet of code working with Oracle Java, but giving exception with IBM J9. . Can someone please help me in resolving the problem?
import java.security.InvalidKeyException;
import java.security.NoSuchAlgorithmException;
import javax.crypto.Mac;
import javax.crypto.spec.SecretKeySpec;
public class TestHM {
public static void main(String args) throws NoSuchAlgorithmException, InvalidKeyException {
String alg = "HmacSHA256";
Mac m = Mac.getInstance(alg);
SecretKeySpec secretKey = new SecretKeySpec(new byte {0}, 1, 0, alg);
m.init(secretKey);
System.out.println("End");
}
}
Current output: Exception in thread "main" java.security.InvalidKeyException: Missing key data at com.ibm.crypto.provider.HmacSHA256.engineInit(Unknown Source) at javax.crypto.Mac.a(Unknown Source) at javax.crypto.Mac.init(Unknown Source) at TestHM.main(TestHM.java:18)

Maybe it doesn't work with 'zero-key'.

Thanks for your response. Mostly you are correct. But I wanted to understand why it fails with IBM J9 and not with oracle jvm. I have tried to see if there are any differences documented, but could not find anything. So, it would be helpful if I can get reference for this behavior documented ? or else any idea about how to debug the root cause for the difference in behavior ?

Basically, they are two different implementations of the same specification; they might very well differ in edge cases.
