Open Source Python Cryptography Software for Linux

The wolfSSL embedded SSL library (formerly CyaSSL) is a lightweight, portable, C-language-based SSL/TLS library targeted at IoT, embedded, and RTOS environments primarily because of its size, speed, and feature set. It works seamlessly in desktop, enterprise, and cloud environments as well. wolfSSL supports industry standards up to the current TLS 1.2 and DTLS 1.2, is up to 20 times smaller than OpenSSL, offers a simple API, an OpenSSL compatibility layer, OCSP and CRL support, is backed by the robust wolfCrypt cryptography library, and much more. wolfSSL relies on the FIPS 140-2 validated wolfCrypt library for all cryptographic functionality.

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

yaSSL, or yet another SSL, is an embedded ssl library for programmers building security functionality into their applications and devices. yaSSL is highly portable, and runs on standard as well as embedded platforms(QNX, ThreadX, VxWorks, Tron) yaSSL is still available but no longer being developed. Current development on the same project continues under wolfSSL. Visit yaSSL Home above for the latest stable release.

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.

A version of Midbar data vault adapted for the ESP32 CYD and WebFlash. It keeps the cryptographic keys in the ESP32 RAM and stores the ciphertexts (encrypted data) in the Google Firebase. The tutorial is available at: https://www.instructables.com/How-to-Turn-ESP32-CYD-Into-a-Secure-IoT-Data-Vault/ WebFlash for ESP32-CYD: https://northstrix.github.io/Midbar-ESP32-CYD-Firebase-Edition/flash WebFlash for ESP32-CYD2USB: https://northstrix.github.io/Midbar-ESP32-CYD2USB-Firebase-Edition/flash

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.

Project to further develop Python Twofish module as released by Enhanced Software Technologies Inc. in order to improve error handling and add OFB/Counter mode, as well as add streaming modes.

Camram is a hybrid antispam system combining multiple techniques improving the users e-mail experience.

This is a swig-based python wrapper for the OpenPACE library.

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.

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.

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

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.

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.

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.

CryptKit is a small, fast cryptographic toolkit for python. It implements Rijndael(AES), SHA 256, Elliptic Curve PKI, Diffie-Hellman key exchange and Nyberg-Ruppel signature/verification. Comprehensive enough to provide a secure socket alternative to SSL

A peer-to-peer chat program that uses public key encryption (via Gnu Privacy Guard) to keep your conversations from the eyes of packet sniffers (*Cough* Carnivore *Cough*)

UnityCA is a Certificate Authority "front end" based on the Community-Oriented CA (COCA) model, which was primarily developed for non-profit "free CAs." Organizational and end-user interfaces provide trusted web management of the installed CA (eg ElyCA).

Confiture is the new generation of the cryptographic software, Confiture use the all new innovation cryptographic.

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.

xhelix: python C extension implementing Helix encryption and authentication. Based on the article named "Helix: Fast Encryption and Authentication" by Niels Ferguson and Bruce Schneier, published in the Nov 2003 issue of Dr Dobbs Journal.

A simple encrypter/decrypter written in C with a graphical user interface written in Python. This tool was written to help forums' users to have their credits for the files they uploaded by putting their usernames from each forum they are active. *This encypting software generates a symetric key based in the password. The lenght of the key is variable. The rule for the length is: (Num_Of_Chars_In_Passwrd)^2 bytes .
