Libkpass is a from-scratch C implementation of reading and writing KeePass 1.x format password databases.

libsparkcrypto is a formally verified implementation of several widely used symmetric cryptographic algorithms using the SPARK programming language and toolset. For the complete library proofs of the absence of run-time errors like type range violations, division by zero and numerical overflows are available. Some of its subprograms include proofs of partial correctness. The distribution contains test cases for all implemented algorithms and a benchmark to compare its performance with the OpenSSL library. The achieved speed has been found to be very close to the optimized C and Assembler implementations of OpenSSL.

LibTomCrypt is a portable ANSI C cryptographic library that supports symmetric ciphers, one-way hashes, pseudo-random number generators, public key cryptography (via RSA,DH or ECC/DH) and a plethora of support routines.

libmcrypt is a cryptographic library that conveniently brings together a variety of ciphers for convenient use. In particular, having libmcrypt allows you to build PHP with encryption.

log2timeline is a computer forensic tool to parse various log files and artifacts found on suspect systems and produce a timeline that can be analyzed by computer forensic examiners.

This program is intended to replace crypt(1), It supports all the algorithms and modes in libmcrypt (BLOWFISH, TWOFISH, DES, TripleDES, 3-WAY, SAFER, LOKI97, GOST, RC2, RC6, MARS, IDEA, RIJNDAEL, SERPENT, CAST, ARCFOUR and WAKE), and is compatibile with UNIX crypt(1) and with des(1) from Solaris.

Sshguard monitors services from their logging activity. It reacts to messages about dangerous activity by blocking the source address with the local firewall. Sshguard employs a clever parser that can recognize several logging formats at once transparently (syslog, syslog-ng, metalog, multilog, raw messages), and detects attacks for many services out of the box, including SSH, FreeBSD's ftpd and dovecot. It can operate all the major firewalling systems, including PF, netfilter/iptables, and IPFIREWALL/ipfw. Sshguard has several relevant features like support for IPv6, whitelisting, suspension, log message authentication. It is reliable, easy to set up and demands very few resources to the system.

NCrypt is intended to give you security in an insecure environment. If you are wanting to encrypt files (particularly on a multi-user system where you don't have root), wishing to hide your activites from prying eyes, and want to "cover your tracks", then NCrypt is for you. It is a symmetrical file encryptor/decryptor that gives you the choice of the top three candidates for AES as the encryption algorithm (Rijndael, Serpent, Twofish), tries to minimize exposure of the plaintext password in memory, and can safely erase the plaintext version from the hard drive. It compiles without any extra crypto libraries, making it ideal for systems where you just have a compiler and basic libraries (such as an ISP's shell server).

Oinkmaster is simple Perl script released under the BSD license to help you update your Snort 1.9+ rules and comment out the unwanted ones after each update. It will tell you exactly what had changed since the last update, hence giving you good control of your rules.

From the README: "oidentd is an ident (rfc1413 compliant) daemon that runs on Linux, FreeBSD, OpenBSD and Solaris. oidentd can handle IP masqueraded/NAT connections on Linux, FreeBSD (ipf only) and OpenBSD. oidentd has a flexible mechanism for specifying ident responses. Users can be granted permission to specify their own ident responses. Responses can be specified according to host and port pairs." FreeBSD's inetd has a built-in ident service which can also generate bogus responses. Please see the TODO file for more information on why only ipf is supported under FreeBSD. Mark Laws mdl@60hz.org
