An attacker runs netcat tool to transfer a secret file between two hosts.

Machine A: netcat -1 p 1234 < secretfile

Machine B: netcat 192.168.3.4 > 1234

He is worried about information being sniffed on the network.

How would the attacker use netcat to encrypt information before transmitting it on the wire?

A.
Machine A: netcat -1 �p �s password 1234 < testfile
Machine B: netcat <machine A IP> 1234

B.
Machine A: netcat -1 �e magickey �p 1234 < testfile
Machine B: netcat <machine A IP> 1234

C.
Machine A: netcat -1 �p 1234 < testfile �pw password
Machine B: netcat <machine A IP> 1234 �pw password

D.
Use cryptcat instead of netcat.

Explanation:
Cryptcat is the standard netcat enhanced with twofish encryption with ports for WIndows NT, BSD and Linux. Twofish is courtesy of counterpane, and cryptix. A default netcat installation does not contain any cryptography support.
