Radamsa is a generic test case generator for robustness testing, aka a fuzzer.
It can be used to test how well a program can stand malformed and potentially
malicious inputs. It operates on given sample inputs and thus requires minimal
effort to set up.
Seahorse is a Gnome front end for GnuPG - the Gnu Privacy Guard program.
It is a tool for secure communications and data storage.
Data encryption and digital signature creation can easily
be performed through a GUI and Key Management operations
can easily be carried out through an intuitive interface.
SSHBlock is a daemon to monitor a syslog log for break-in attempts using
SSH, and to automatically block bad hosts by adding lines to /etc/hosts.allow
(TCP Wrappers). Several thresholds are pre-defined, to be able to block those
trying many attempts within a longer or shorter period.
SSLsplit is a tool for man-in-the-middle attacks against SSL/TLS encrypted
network connections. Connections are transparently intercepted through a
network address translation engine and redirected to SSLsplit. SSLsplit
terminates SSL/TLS and initiates a new SSL/TLS connection to the original
destination address, while logging all data transmitted. SSLsplit is intended
to be useful for network forensics and penetration testing.
Provide a fast way to delete entries from OpenSSH's known_hosts
file. This is a simple automation of the things normally done by
the user when having an "offending key" in his/her known_hosts file
caused by a changing host key of the destination.
The Yubico PIV tool is used for interacting with the Privilege and
Identification Card (PIV) application on a YubiKey.
With it you may generate keys on the device, importing keys and
certificates, and create certificate requests, and other operations. A
shared library and a command-line tool is included.
VNCcrack is a fast offline password cracker for VNC passwords.
By sniffing a VNC challenge-response sequence off the network
(typically when VNC is used without a decent cryptographic
wrapper like SSH or SSL), you can recover the password fairly
easily and quickly by letting VNCcrack pound on it.
"YARA is a tool aimed at helping malware researchers to identify and classify
malware samples. With YARA you can create descriptions of malware families
based on textual or binary patterns contained on samples of those families.
Each description consists of a set of strings and a Boolean expression which
determines its logic."
This is a reimplementation for Unix, by Byron Rakitzis, of the Plan
9 shell. rc offers much the same capabilities as a traditional
Bourne shell, but with a much cleaner syntax.
See the end of the man page, under "INCOMPATIBILITIES" for (known?)
differences from the "real" rc.

Sievelog is a message dispatcher inspired by swatch but more focused on the
following problems:
* Having a clean syntax
* Directing a raw syslog stream to different files based on content
* Mailing out alerts based on content
* Being fast
Sievelog's syntax is as simple as "<regex>" -> /some/file.
