Protocol Specification Tool is a system for executable specification, verification and rapid prototyping of cryptographic protocols.

PureBasic Shamir Secret Sharing is an open-source, self-contained and educational implementation of the Shamir Secret Sharing Scheme, written entirely in PureBasic. Shamir Secret Sharing is a cryptographic method that splits a secret into multiple parts (shares), such that any combination of at least T shares can reconstruct the original secret, while any number of shares fewer than T reveals no usable information. This implementation operates over the finite field GF(257), allowing correct handling of all byte values (0–255) without loss, making it compatible with any type of string or binary-compatible data. Main Features Complete implementation of Shamir Secret Sharing Arithmetic over GF(257) Compatible with all character strings Robust Lagrange interpolation Safe modular inverse computation Shares encoded in hexadecimal (3 characters per byte) Clear, well-commented source code ⚠️ Disclaimer This project is intended for educational and demonstration

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.

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.

PyGestPayCrypt is the Python implementation of GestPayCrypt and GestPayCryptHS classes for italian Banca Sella GestPay online credit card payment system.

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

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.

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.

PyTextCryptor is a simple python program to encrypt text, and easy to use. I can save to a file(.cro). It uses PygGtk, and python.

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.

RotNN is a Python module that implements rotation encryption/obfuscation. The default action is similar to rot-13, but it can also rotate over the entire UNIX printable character set.

Very simple wrapper for using some common pgp commands from within python. Requires PGP5.0i or better(ish).

Python3 port of Frank Tobin's Python GnuPGInterface incorporating the --keyring and --secret-keyring patch. "Python 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" and identical to the Python2 module GnuPGInterface.

Dm-crypt + LUKS encrypted device manager. Available functions : open, close, create, show info, add key, remove key, change key. Most important functions : change encryption parameters and reencryption with new master key - both in-place & failsafe.

A program to calculate and verify checksums of multiple files with wizard-like GUI. Supports 12 hashes: CRC32, MD2, MD4, MD5, SHA1, SHA2, RIPEMD,Whirlpool, ED2K, AICH, Tiger, TTH. Allows processing of nested directories and updating of checksum files

The QR-CERT software is a specialized package of applications dedicated for the development of a Public Key Infrastructure system as well as the cards personalization and management system. The software contains a number of functional modules, enabling a flexible selection of functionalities for implementation. The software is dedicated for large organizations and corporate environments, with a PKI infrastructure and microprocessor cards. The QR-CERT is a solution both for the companies which plan to build their own PKI infrastructure and entities planning to provide services in this respect. This software enables the implementation of advanced security mechanisms, such as: secure e-mail (S/MIME), electronic signature (PKCS#7, XAdES), network transmission protection (IPSEC, SSL/TLS) and strong authentication for service portals (HTTPS) or strong authentication of users for the Windows ActiveDirectory domain.

QSSL is an library that enables SSL/TLS support for the Qt library from Trolltech.

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.

A fast and flexible implementation of SSH and SCP for Java, modelled on OpenSSH. In the beginning it should be simple, but hopefully eventually feature-rich.

The RAZip bitstream format was designed to provide a faster random access to compressed data than what is currently possible using the GZIP format. During the desing phase, some other features were added, like encryption and error correction.
