The OpenBSD project produces a free, multi-platform 4.4BSD-derived UNIX-like operating system. Emphasizing portability, standardization, coherency, correctness, proactive security and integrated cryptography. It comes with almost 9000 software package in its ports, including a custom X11 environment (Xenocara), desktop environments, web and multimedia applications, compilers and programming languages. It also harbours the OpenBSD-maintained software projects OpenSSH, LibreSSL, OpenIKED, OpenBGPD

OpenSSH is a BSD/Linux implementation of SSH1 and SSH2 for encrypted terminal connections, tunneling and file transfers. It includes the sshd server, scp and sftp, and various utility tools such as ssh-add, ssh-agent, ssh-keysign, ssh-keyscan, ssh-keygen, and the sftp-server.
Detroit is a POSIX platform abstraction layer for creating small and portable desktop applications. Detroit offers simple widgets, even more simpler menu system and extensible DSL language in its core.
A command-line network packet crafting and injection utility for UNIX, Linux, and Windows.
This is htop, an interactive process viewer for Unix systems. It is a text-mode application (for console or X terminals) and requires ncurses.
fwknop implements an authorization scheme known as Single Packet Authorization (SPA) for strong service concealment. SPA requires only a single packet which is encrypted, non-replayable, and authenticated via an HMAC in order to communicate desired access to a service that is hidden behind a firewall in a default-drop filtering stance. The main application of SPA is to use a firewall to drop all attempts to connect to services such as SSH in order to make the exploitation of vulnerabilities (bot
The WendzelNNTPd is a IPv6-ready NNTP usenet-server with the main goal to be as easy to use as possible. It is portable (Linux/*BSD/*nix), supports AUTHINFO authentication, contains ACL as well as role based ACL and supports invisible newsgroups. It currently supports MySQL and SQLite backends.
LUKSUS is a text-based program for Linux and BSD which runs in a terminal window or console. LUKSUS lets you encrypt your files, hardrives, usb sticks and virtual container using your operating system's internal encryption mechanism and acts as the frontend to the internal encryption mechanism. It can use the following encryption facilities: LUKS, Truecrypt, GELI and GNUPGP. It works on Linux, DragonflyBSD and FreeBSD. LUKSUS can also encrypt single files with GNU Privacy Guard or OpenSSL.
