dig -k ?

[David Carmean]

I can't seem to figure out how to set up and use a TSIG keyfile 
with dig.  I've got it to work with "-y keyname:key" on the command line, 
but I'd rather not hang my jewels out for the other users on the 
system to see, so to speak.  I've tried just the bare mime-encoded 
string with "keyname:filename", and a snippet formatted as in the 
usual key clause, with no luck.

Thanks....
