from http://farm9.org/Cryptcat/: CryptCat Project Cryptcat is the standard netcat enhanced with twofish encryption with ports for WIndows NT, BSD and Linux. Twofish is courtesy of counterpane, and cryptix. TCP/IP swiss army knife extended with twofish encryption - Cryptcat is a simple Unix utility which reads and writes data across network connections, using TCP or UDP protocol while encrypting the data being transmitted. It is designed to be a reliable "back-end" tool that can be used directly or easily driven by other programs and scripts. At the same time, it is a feature-rich network debugging and exploration tool, since it can create almost any kind of connection you would need and has several interesting built-in capabilities. I find this tool to be pretty useful myself. The IPV6 patch that is used with netcat will also patch cleanly with cryptcat (one small hand-fixable .rej), but since i don't use ipv6 at all, i decided not to include it in my ebuild
