Netcat vs Cryptcat

Netcat is a simple command-line utility and is available for Linux, Unix, and Windows platforms.

It is designed to read information from connections using the TCP or UDP protocol and perform a simple port redirection on them as configured.

However, Netcat has a drawback and an attacker can exploit it by passively sniffing the communication channel.

Cryptcat=Netcat + Encryption (TwoFish)

Instead of Netcat, you can use Cryptcat to secure your communication channel. However, you are not the only one who can use it, as the attacker can do exactly the same.
