That's my thought as well. I don't want to know exactly how the 
algorithm generates strings. But, I think that if I analyze enough 
strings I should know, on some level, what an acceptable string looks like.

Samba coders never see Microsoft's file and print sharing source code, 
yet they are able to emulate an NT server quite well just by observing 
packets.
