encrypting netcat 1.10

I've added a trivial RC4 encryption support for popular Netcat 1.10. It works like this: $ ./nc -l -k dupa-20 -p 12345 >received.txt & $ ./nc -vv -k dupa-20 localhost 12345 <README Where "-k" argument is the key. It's trivial and doesn't support *any* data integrity checking. But it's fast and suitable for bulk data transfers, when performance is the primary aim. -- Paweł Krawczyk *** home: <http://ceti.pl/~kravietz/> security: <http://ipsec.pl/> *** fidonet: 2:486/23
