stegfs is a steganographic file system in userspace. It uses the FUSE module which allows it to be incorporated into more than just the Linux Kernel, i.e. it's also known to work in FreeBSD :) For more details visit: https://albinoloverats.net/projects/stegfs

A large integer arithmetic library written in plain C.

A multi-platform tool to convert RSA private keys between SFM format (modulus, public exponent, private exponent) and CRT format, in both ways.

AUM is an extremely fast, small-state, cryptographically secure pseudo-random number generator and stream cipher. AUM exhibits uniform distribution, mixes rapidly, has no detected bias, and comes in three variants: AUM16, with an internal state array of 16+4 32-bit words; AUM32, with an internal state of 32+4 words; and AUM64 with a 64+4-word state. The former permit seeding with a key of up to 512 or 1024 bits, the latter with a 2048-bit key.

MOTET is a tiny, fast super-encipherment application written in C, featuring the new CSPRNG/stream ciphers MOTE and BEDBUG in each of their three variants, as well as the "gold standard" among ciphers, ISAAC. MOTET brings multiple levels of encryption, including a ciphertext-hash, a Vigenere mixing function, a choice of Caesar MOD or Caesar MIX ciphering on the primary key-stream, plus a deeply scrambled "outer shell" as a final super-encryption stage. A unique nonce IV guarantees that...

MOTE is a fast, small-state, cryptographically secure pseudo-random number generator (CSPRNG) and stream cipher. MOTE exhibits uniform distribution, mixes extremely rapidly, has no detected bias, and comes in three variants: MOTE8, with an internal state array of 8+4 32-bit words; MOTE16, with an internal state of 16+4 words; and MOTE32 with a 32+4-word state. The former permit seeding with a key of up to 256 or 512 bits, the latter with a 1024-bit key. Reduced to essentials, MOTE is only...

BEDBUG is a small, fast, cryptographically secure pseudo-random number generator (CSPRNG) and stream cipher. It exhibits uniform distribution, mixes rapidly (with worst-case avalanche better than 16-bits), has no detected bias, and comes in three variants: BEDBUG128, with an internal state array of 128+3 32-bit words; BEDBUG256, with an internal state of 256+3 words; and BEDBUG512 with a 512+3-word state. The former permit seeding with a key of up to 4096 or 8192 bits, the latter with a...

This is a community effort to study and improve security of WPA protected WiFi networks.

libstego is a set of libraries that implement functionality to embed secret data into a wide range of image file formats and uncompressed audio formats.

mcrypt, and the accompanying libmcrypt, are intended to be replacements for the old Unix crypt, except that they are under the GPL and support an ever-wider range of algorithms and modes.

BBSGen is an improved Blum-Blum-Shub pseudorandom number generator. It consists of a C library (libbbsgen) and command-line tool (bbsgen). BBSGen can be used in applications and command-line as secure, unpredictable and strong PRNG.

Interrogate is a proof-of-concept tool for identification of cryptographic keys in binary material. First and foremost for memory dump analysis and forensics usage. Able to identify AES, Serpent, Twofish and RSA keys as of version 0.0.3.

A GLib/GTK+ classical encryption analysis and reversal tool that brings together multiple techniques into a single program to aide in decryption.

stegotools is a suite of UNIX command-line applications to read/write hidden information from/in files using steganography. It currently fully supports 24bpp bitmap images.

LightCrypto is C cryptography library. It contains Big Number Library, basic crypto algorithms (3DES, DSA, RSA, ECDSA, etc), Internet Voting Scheme, and many more. Current librarie's binary is less than 1MB and it can even be smaller by user config.

EverCrack cryptanalysis engine. The goal is cryptanalysis of any class of cipher. The focus now is the kernel - cryptanalysis of unilateral monalpha substitution ciphers extremely quickly, and later, cryptanalysis of complex ciphers for the kernel.

Convolutional Hashing Algorithm. Provably secure hashing algorithm based on worst case assumptions on cyclic-lattices.

This application provides, for everyone, a cryptographic implementaion of the RSA, AES and RC4 algorithms. Steganography is also supported, providing a secure transfert solution. The goal is to make all people access to this nice cryptographic world :)

PalmOS MD5 algorithm Shared Library

siggen is a cool email signature generator for encrypted ansi c (confused), brainf*ck, ... signatures. Use it in combination with vi(m), emacs, mutt, pine, or what ever. (tested on Solaris, Linux and Windoze). Optimized only for geeks :-)

This is a very powerfull criptography project that basicaly can be used to transmit or store secure data and study some cipher, hash and compression algorithms to understands how it works.

Development area for GNU/Linux 2.6.x for the KS8695 ARM SoC. Covers kernel patches, drivers for serial, Ethernet, PCI, GPIO, watchdog subsystems, and drivers for optional PCI based devices such as USB, WiFi, WiMAX, IPSec, SSL, and RSA devices.

Qryptix consists of a PAM object and utilities for session- and key-management for encrypted home directories using the International Kernel (CryptoAPI) patches for Linux. It simplifies login/logout, mounting/unmounting, and key generation and changing.
