Open Source Python Cryptography Software

Simple drag & drop file encryption tool. based on python and uses PyCrypto to encrypt the inputted files with AES encryption. Then sqlite database file is generated with a unique key to store the encrypted files and folders in binary blobs for later decryption.

Cryptography Tools is a project to develop demonstration tools on classic (currently Caesar and Playfair) & modern crypto-systems, including private & public key encryptions, digital signatures, cryptographic hashes and authenticated encryption.

PyMe is a Python interface to GnuPG functions. It is based on GPGME library.

CCryption is a simple opensource text encryption program, please visit: http://anprogram.net/ccryption-opensource/

Hide secret messages in your pictures! Cyberbit lets you transmit a secret message to an intended person in a new manner. The secret message is an 1-bit deep black & white image. The message can contain written text, a drawing, a secret code etc. Using Visual Cryptography the application splits the secret message into two "shadow images" called <<shares>>. Any of the two shares will be embedded into a "normal" image file called by tradition <<vessel>>. You can use a method of hand to send the two vessels to your correspondent. For instance you can post one vessel image on facebook. The other vessel image can be sent as an attachment of an e-mail. The vessel images can be 8-bit gray-level images or 24-bit deep true-color images. Anyone who can correctly spot the two vessels and knows the dimensions of the image containing the secret message will be able to decrypt the secret message using the Cyberbit application.

FSFS is a secure distributed file system in user space built over FUSE and OpenSSL. It stores AND transfers data between clients and server in secure form, leaving most of the cryptography to the clients, thus relieving the server of the additional work.

https://www.garanet.net/it-blog/python-password-manager/ A Python3 Password Manager, with encryption and without an Internet connection. How it Works: First Run: PyPWD > Creates Master Key with your master username and password (Do not forget it or modify the config file, otherwise you'll be not able to open your password manager anymore). PyPWD > Saves a DataFrame as an encrypted CVS and all passwords are encrypted too, with key and the master password. Login: PyPWD > Dencrypts the password file, based on the username and password filled.

Pyton GnuPGInterface is meant to be a filehandle-concentrating Python interface to GnuPG, the GNU Privacy Guard. It has an API similar to the Perl module GnuPG::Interface.

Python OpenSSL Wrappers(POW), a Python wrapper for OpenSSL. X590v3 and CRL encoding is now also support is now via a pure Python module, which will include support for PKCS in the near future.

secureDATA is a simple and easy to use encrypted personal information manager. It can store both textual information (passwords, usernames, electronic receipts, etc), and (as of v1.6) files. It uses AES-128 encryption via the Python Cryptography Toolkit.

A tight python crypto module implementing only the latest and greatest: Rijndael (AES) symmetric cipher in 128, 192 and 256 bits supporting password encryption, SHA 256 and several CSPRNG schemes in pure python.

CryptoPy is a pure python implmentation of cryptographic algorithms and applications. The algorithms are developed for readability more than speed. The collection now includes IEEE 802.11i specific algorithms that generated the test vectors for 802.11i.

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.

DCrypt is an encryption and decryption tool that combines in a smart way multiple algorithms. The combination of multiple strong algorithms makes it much more difficult for hackers to get the plain content of the encrypted file without the password.

My first attempt at a one-way hashing class/algoritm, built as a python class. It produces variable length hash from a message block of the size you want. The resulting hash will be ~2x the message block in size, and should provide for at least as many bits of security as the block itself. I updated this, with a different hash than original, since I found a potential collision on some blocks, not but specific to that challenge. To further correct this, I modified the padding when it's less than the block size. I hold no guarantee of the security of this algorithm, USE AT YOUR OWN RISK. I have had no 3rd party analysis done on the algorithm to date, but research is welcome, and a challenge is even provided in CHALLENGE.txt.

Kojoney is an easy of use, secure, robust and powerfull Honeypot for the SSH Service written in Python. With the kojoney daemon are distributeds other tools such as kip2country (IP to Country) and kojreport, a tool to generate reports from the log fi

OpenSEED is open source implementation for SEED, the 128-bit Symmetric Block Cipher which is used widely among Korean Financial & Banking Companies. OpenSEED will implement TLS over SEED, also.

Visual Cryptography is a graphical form of information concealing. In a 2-out-of-2 Visual Cryptography Scheme a dealer will "split" a secret image into two shares, print the shares onto separate transparencies and hand them to the participants to the scheme. If the two participants come together, they'll be able to reveal the secret image without a computer, perfectly superimposing the transparencies they own. Analyzing a single share, no one will be able to obtain any information considering the secret image no matter the computing or the analyzing power. In an Extended Visual Cryptography Scheme, both the secret image and the shares are meaningful images like a landscape, a building or a beautiful girl, hiding the very intention to conceal a secret. PyEvcs is a command line Python application allowing you to experiment with Extended Visual Cryptography Schemes for "natural" continuous tone images.

PyGFS is a reliable and secure distributed file system that runs completely in userspace. It supports x509 certificate authentication, authorization and encryption mechanisms to provide secure access over insecure networks.
