Signatures on GnuPG

[Matt Red]

HI there, 
I am interested in using this nice looking software, but I see some 
problems with 
teh signatures.  The key I down loaded from the web site is this  
1024D/57548DCD 1998-07-07 Werner Koch (gnupg sig) <dd9jn@gnu.org>
that is from your web site (official GnuPG).

I am puzzled to find that the rpm's that I down load are signed with 
"pg: Signature made Mon Jan 17 04:21:20 2000 EST using DSA key ID 
3DCB0CDC."

Any suggestions?  Where is this other key available?  Why the 
discrepancy?

Thanks, 

Matt
