sbd 1.31

is a Netcat-clone, designed to be portable and offer strong encryption. It runs on Unix-like operating systems and on Microsoft Win32. sbd features AES-CBC-128 + HMAC-SHA1 encryption (by Christophe Devine), program execution (-e option), choosing source port, continuous reconnection with delay, and some other nice features.
Only TCP/IP communication is supported. Source code and binaries are distributed under the GNU General Public License.
sbd can be used for any number of network-related things, for example.:
Secure file transfer
Remote administration
Simple (but secure) peer-to-peer chat
Pen-test tool (crypto avoids NIDS detection and telnet-style traffic recording)
To compile sbd under a Unix-like operating system you need gcc and relevant
development tools. For Linux, FreeBSD, NetBSD, OpenBSD (and possibly others),
type:
make unix
Enhancements:
- if sbd is setuid (chmod 4755 or 6755), sbd will do setuid(geteuid()) on Unix-like operating systems. feature added to offer root shells during pen-tests.
- the host, port and command to execute (-e option) specified on the command line are wiped with spaces in order to hide them from the process list on Unix-like operating systems (e.g. "ps auxww", "ps -Af", e.g.). the -k option was wiped with stars (*) before, but now its all wiped with spaces (0x20) instead.
