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

He is worried about information being sniffed on the network.
How would the attacker use netcat to encrypt the information before transmitting onto the wire?


A. Machine A: netcat -l -p -s password 1234 < testfile
Machine B: netcat <machine A IP> 1234
B. Machine A: netcat -l -e magickey -p 1234 < testfile
Machine B: netcat <machine A IP> 1234
C. Machine A: netcat -l -p 1234 < testfile -pw password
Machine B: netcat <machine A IP> 1234 -pw password
D. Use cryptcat instead of netcat
