Stegdetect is an automated tool for detecting steganographic content in images. It is capable of detecting several different steganographic methods to embed hidden information in JPEG images. Currently, the detectable schemes are jsteg, jphide, invisible secrets, outguess 01.3b, F5, appendX, and camouflage. Using linear discriminant analysis, it also supports detection of new stego systems. Stegbreak is used to launch dictionary attacks against JSteg-Shell, JPHide, and OutGuess 0.13b.

AES Encryption for Shell Scripts provides strong encryption/decryption using the Advanced Encryption Standard algorithm "Rijndael" to do 128-bit encryption. It is intended for use in shell scripts or as part of a larger cryptosystem, not as a standalone program.

gpgdir is a script that encrypts and decrypts directories using a GPG key specified in ~/.gpgdirrc. It supports recursively descending through a directory in order to make sure it encrypts or decrypts every file in a directory and all of its subdirectories. All file mtime and atime values are preserved across encryption and decryption operations. In addition, gpgdir is careful not to encrypt hidden files and directories.

Libgcrypt is a general-purpose cryptographic library based on the code from GnuPG. It provides functions for all cryptographic building blocks: symmetric ciphers (AES, DES, Blowfish, CAST5, Twofish, and Arcfour), hash algorithms (MD4, MD5, RIPE-MD160, SHA-1, and TIGER-192), MACs (HMAC for all hash algorithms), public key algorithms (RSA, ElGamal, and DSA), large integer functions, random numbers, and a lot of supporting functions.

The Paketto Keiretsu is a collection of tools that use new and unusual strategies for manipulating TCP/IP networks. They tap functionality within existing infrastructure and stretch protocols beyond what they were originally intended for. It includes Scanrand, an unusually fast network service and topology discovery system, Minewt, a user space NAT/MAT router, linkcat, which presents a Ethernet link to stdio, Paratrace, which traces network paths without spawning new connections, and Phentropy, which uses OpenQVIS to render arbitrary amounts of entropy from data sources in three dimensional phase space.

ccrypt is a command line utility for encrypting and decrypting files and streams. It was designed as a replacement for the standard Unix crypt utility, which is notorious for using a very weak encryption algorithm. ccrypt is based on the Rijndael cipher, which is the U.S. government's chosen candidate for the Advanced Encryption Standard (AES). This cipher is believed to provide very strong security. A compatibility mode is included for decrypting legacy "unix crypt" files.

Libecc is a C++ elliptic curve cryptography library that supports fixed-size keys for maximum speed. The goal of this project is to become the first free Open Source library providing the means to generate safe elliptic curves, and to provide an important source of information for anyone with general interest in ECC.

crypt_blowfish is an efficient implementation of a modern password hashing algorithm, based on the Blowfish block cipher, provided via the crypt(3) and a reentrant interface. It is compatible with bcrypt as used in OpenBSD. It is adaptable to future processor performance improvements, allowing you to arbitrarily increase the processing cost of checking a password while still maintaining compatibility with your older password hashes. The hashes it produces are several orders of magnitude stronger than traditional Unix DES-based or FreeBSD-style MD5-based hashes.
