Yes I did try using that (in fact it's in the code I sent) but when you are 
printing out a 1024 bit key, it's not very useful. What I want is something 
like:

00:01:02:03:04:05:06:07:08:09:0a:0b:0c:0d:0e:0f
10:11:12:13:14:15:16:17:18:19:1a:1b:1c:1d:1e:1f
etc

so you can eyeball the octet you are looking for.

Should a function like the one I want (and posted) go in NumExts?
