gnu.java.security.provider.MD5 should extend java.security.DigestMessage
instead of DigestMessageSpi, because now it throws exception:
java.lang.ClassCastException:
gnu.java.security.provider.MD5 cannot be cast to java.security.MessageDigest
when trying to MessageDigest.getInstance("MD5").
public class t {
public static void main(String[]argv) {
try {
java.security.MessageDigest.getInstance("MD5");
} catch(Throwable t) {
t.printStackTrace();
}
}
}
Bellow are the changes I made to get it work. Can you, please, commit them?
