Open Source Python Cryptography Software

The name leet stands for "Linux exquisite encryption tool", it will be a software application for on-the-fly encryption, similar in its functionality to TrueCrypt. The goal of leet however is to be simpler and as user friendly as possible, making encryption and securing of information accessible to anybody, even those who don't necessarily have any prior knowledge of data securing, algorithms and encryption. However it's not targeted at this group of users only, part of the ambition of this project is to reach companies, institutions, governments (etc...) as well.

CryptoHawk can calculate hashes (md2,md4,md5,sha-1,sha-256 and hmac). It can also perform cryptanalysis like frequency analysis for substutition cipher and exhaustive key search for rotation cipher, as well as searching internet databases for md5 hashes.

Cia project tries to develop an all-purpose security tool. It's composed by ctools, the security tool; cfs, the app and cfs-server, a file & key server.

This project's goal is to provide a simple but extendable SOC (System On Chip) that can be loaded into an FPGA in order to quickly test custom coprocessors and evaluate their robustness against SCA (Side Channel Attacks) or others physical attacks.

The Free Digital Money project aims to promote ideas and stimulate further innovation in the field of digital money. It provides a e-money implementation that can be used by anyone to try out ideas, build sample applications, or for further development.

Application written in Python, that hides information from a file into a PNG image.

Encryption with symmetric-key algorithm Kirmah - generate keys with exotic chars - redefine key length - key mark to ensure decryption capabilities - mix data - fast with multiprocessing - possible compression - gui on gtk3 - cli tool - python3 DEPENDENCIES : ======== python3, python-gobject, gobject-introspection, pygtk 3 modes are available to encrypt : ======== - compression (full / disabled or only final step) - random (simulate a random order - based on crypted key - to randomize data) - mix (mix data according to a generated map - based on crypted key - with addition of noise) Process is as follow : ======== encrypt : file > [ compress > ] encrypt > [randomiz data > mix data > compress > ] file.kmh decrypt: file.kmh > [ uncompress > unmix data > unrandomiz data] > decrypt > [uncompress > ] file ======== for encrypt/decrypt large binary files, use the fastest alternative : split/merge

This is a steganogric program that uses images last bits to hide information ( files ). It can crypt data with a rotation and a xor key.

libgcrypt-py is a Python wrapper around the libgcrypt cryptographic library. It supports functionality/algorithms that are supported by libgcrypt, including Symetric Ciphers (3DES, AES, Twofish, Blowfish), Cryptographic Hashing (MD5, SHA1, RIPE-MD160), P

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.

The aim of this small program is to parse your address book (Evolution address book or VCard file for the moment) and check if some of your contacts have uploaded a PGP public key on a key server.

Pena is an acronym for "Pena Encryption for Automata". This framework will help you to run encrypted representations of programs.

Simple python program to encrypt up to 255 character text into .png or .bmp images. VIEW the README for further instructions as well as image specifications. Used pyinstaller to compile into an .exe ---Feedback is welcome ---

We're working on developing a standard encryption API for the Python language, and building a set of standard cryptography modules. The CVS tree is open to anyone who needs it for a Python/crypto related package.

PyPassMan is a password manager that allows user to store passwords and password-related informations. It uses a strong cryptographic library to ensure information security. Its aim is to organize those informations in a simple and efficient way.

PyPasswordSafe is a Python module for reading, searching, and displaying PasswordSafe v3 (http://passwordsafe.sourceforge.net) data files.

SAT solvers are being used more and more in partial key exposure attacks. The scope of this script is to show that SAT solvers can be used in partial key exposure attacks of RSA with very good results.

TLS Lite is a python library for SSL/TLS. It supports non-traditional authentication methods such as SRP, shared-keys, and cryptoIDs, as well as X.509 certificates.

TMDA is an open source anti-spam system and local mail delivery agent written in 100% pure Python. TMDA combines whitelists, blacklists, a challenge/response system, and special-purpose e-mail addresses called "tagged addresses" to thwart spam.

Live Security/Forensics Linux Distribution, built from scratch and packed full of tools useful for vulnerability analysis, penetration tests, and forensic analysis.

TrustedPickle is a Python module which lets you create and sign your data files. By using public/private key techniques, this module protects your users from loading malicious data files that others might claim you created. LEGAL FOR EXPORT.

Colombiana is a tool used to recover, from given strings X and Y possible functions F : F(X) = Y. Very customisable, can recover a lot of functions.

pyMoul: Python tools for Myst Online - URU Live (MOUL)

A firewall knocking mechanism that is loosely based on tumbler (tumbler.sourceforge.net) instead it is written in python. A focus of this implementation will be on multiple client implementations (OSX Widget, XP taskbar, etc.)

Python module importer to import from archives. Demonstrates importing modules from AES encrypted zip archives. Experimental status.
