Mussh is a shell script that allows you to execute a command or script over ssh on multiple hosts with one command. When possible mussh will use ssh-agent and RSA/DSA keys to minimize the need to enter your password more than once.

NaCl (pronounced "salt") is a new easy-to-use high-speed software library for network communication, encryption, decryption, signatures, etc. NaCl's goal is to provide all of the core operations needed to build higher-level cryptographic tools. Of course, other libraries already exist for these core operations. NaCl advances the state of the art by improving security, by improving usability, and by improving speed.

Pairing-based cryptography is a relatively young area of cryptography that revolves around a certain function with special properties. The PBC (Pairing-Based Cryptography) library is a free C library (released under the GNU Public License) built on the GMP library that performs the mathematical operations underlying pairing-based cryptosystems. The PBC library is designed to be the backbone of implementations of pairing-based cryptosystems, thus speed and portability are important goals. It provides routines such as elliptic curve generation, elliptic curve arithmetic and pairing computation. Thanks to the GMP library, despite being written in C, pairings times are reasonable.

Platform-independent tool for Authenticode signing of EXE/CAB files - uses OpenSSL and libcurl. It also supports timestamping.

Avcheck is a simple program that allows you to call an antivirus software in order to check mail messages for viruses before actual delivery from within a Mail Transfer Agent, or MTA. Avcheck itself isn't a virusscanner, nor it is an MTA. It sits between the MTA and a real antivirus software. Most MTAs available today can call an external program for every mail message in order to perform various tasks, including virus scanning and content filtering. Avcheck can be used as that external program. Avcheck will receive a mail message from a mail system, pass it to an antivirus software, and, depending on the presence of a virus in that message, will either allow the message to be delivered or take appropriate actions to handle infected mail. Avcheck does nothing with a mail message contents -- it's task is to prepare file with a mail message and feed it to an antivirus progra. It's an antivirus task to decode MIME structure, handle embedded archives and so on. Many but not all antivirus products today have this ability.

BeeCrypt is an open source cryptography library that contains highly optimized C and assembler implementations of many well-known algorithms including Blowfish, MD5, SHA-1, Diffie-Hellman, and ElGamal. Unlike some other crypto libraries, BeeCrypt is not designed to solve one specific problem, like file encryption, but to be a general purpose toolkit which can be used in a variety of applications. The BeeCrypt library currently includes: - Entropy sources for initializing pseudo-random generators - Pseudo-random generators: FIPS-186, Mersenne Twister - Block ciphers: Blowfish - Hash functions: MD5, SHA-1, SHA-256 - Keyed hash functions: MD5/HMAC, SHA-1/HMAC, SHA-256/HMAC - Multi-precision integer library, with assembler-optimized routines - Probabilistic primality testing, with optimized small prime trial division - Discrete logarithm parameter generation over a prime field - Diffie-Hellman key agreement - DHAES encryption scheme - ElGamal signature scheme (two variants) - Basic RSA primitives and key pair generation

checkpassword-pam was written from scratch. There are several older packages called checkpassword-pam, derived from DJB's checkpassword code. This checkpassword-pam is more modern and administrator-friendly.

Chaosreader is a perl script that parses snoop or tcpdump logs and extracts sessions for a number of different appplications: ssh, telnet, smtp, irc, ftp, etc. The data are formatted into an html file and can be used to replay some sessions. Sshkeydata is a perl script that attempts to recreate ssh sessions extracted by chaosreader by estimating what commands may have been typed. Both scripts are installed in ${PREFIX}/bin

* This is a utility to (re)set the password of any user that has a valid (local) account on your NT system. * You do not need to know the old password to set a new one. * It works offline, that is, you have to shutdown your computer and boot off a floppydisk or CD. * Will detect and offer to unlock locked or disabled out user accounts! * It is also an almost fully functional registry editor!

A native MD5 implementation in Common Lisp. This package is compiled with SBCL.
