small-filesize option for encryption

[Joe Presto]

Hi all - 

I'm looking into building a remote support module (for Win98 through server
2003) around RealVNC (actually, my bid is out at Rent-a-coder
http://www.rentacoder.com/RentACoder/misc/BidRequests/ShowBidRequest.asp?lng
BidRequestId=207431 in case anyone is interested!) that will enable me to
send a customer a file, unpack and connect back to me with encryption,
avoiding any firewall issues on their end.

 

It's easy enough - without encryption.  But with encryption I'm running into
a size problem.

 

I was hoping to come in around 400k or so for the executable.  But stunnel
appears to be a few megs by itself, and the OpenSSH dlls are 3 megs or so
(the server will need to be at the customer end, since it is connecting
out).

 

Are there any smaller solutions I should look at?  Or can I expect to be
able to recompile these without excess features to save some space?

 

Thanks!  Joe
