Good idea.

Still, I am not sure about all those methods taking InputStream as an input. Most likely I would use this class for debugging purpose, so any side effect (advancing inside an InputStream or ByteBuffer) might not be desirable. 

Another question, I just noticed that sun.security.HexDumpEncoder emits uppercase letters (ABCDEF) and your code emits lowercase letters. Do we need to provide user a choice here?

Thanks
