A more modern wiki focusing on open technologies like SOAP and XML, and upon a more focused form of wiki software that incorporates the elements of traditional content creation, such as from journals, books or periodicals.

platform independent solution to encrypt files on a portable Device. Files will be encrypted with TripleDES and hold in an XML-File. No local Installation needed.

PortableNotary permits you to verify pdf signature. Is OS independent and can be used from command line.

'Portfolio Secure' is an desktop application developed using python 3.6.8 and other add-on libaries. Can secure files or folders by encrypting into a unreadable file (.enc) . Portfilio secure has two parts: 1) Folder Guardian - converts folders into unreadable file (.enc) 2) File Guardian - converts files into unreable file (.enc) Compatible only for windows OS.

Pot of Gold is an open source implementation of Philippe Oechslin's "Faster Cryptanalytic Time-Memory Trade-Off" paper. It performs precomputation on a particular hash algorithm which can be later used to reverse certain hashes.

Power Hasher is a program that allow you to get the hash code of multiple files at once, and export the results to a file, making easy for this file to be imported and the files checked. Currently it supports MD5, SHA1, SHA256, SHA384 and SHA512.

The PowerCiph Data Encryption Algorithm is a versatile, yet simplistic, encryption algorithm/protocol. The ultimate goal of the algorithm is simplicity, compactness, and a lack of prerequisites.

I wrote this in 1997. Right now I have the basic code up. I have it in c++ too but I have yet to upload it. This program is good for small files but does not handle large files very well. It creates a binary key to increase the entropy of your file. It can use the key to reverse the entropy of your file. So, it encrypts and de-crypts.

Primary Cryption -- a data protection tool. Uses thousands of prime numbers as sources of pseudorandom digits for performing extremely strong encryption of multiple files. The key is an average ordinary file; its content is used to select the primes.

Use prime numbers and pseudorandom number generators to create pseudorandom permutations to "shuffle" bits of given data (passwords, logins, PINs, files, directories). It is designed to be very secure (I hope so).

An application that offers comprehensive functionality in the range of digital certificate's management and the possibility of file and directory encryption.

Software contenitore per crittare file. E' possibile creare un albero di cartelle e gestirle a proprio piacimento, i file inseriti nel programma vengono automaticamente crittati e mostrati come in esplora risorse. Tutti i dati crittati vengono gestiti da un file salvato in una posizione decisa dall'utente. E' possibile gestire più archivi, e salvarli su pen-drive o altro supporto removibile. . Container software to encrypt files. It is possible to create a tree of folders and manage them as you wish, the files inserted into the program are automatically encrypted and shown as in Windows Explorer. All encrypted data is managed by a file saved in a location decided by the user. It is possible to manage multiple archives and save them on a pen drive or other removable media. . Supported operating systems: Windows™ x86 / 64bit

This program makes it possible to transfert files from a computer to another via SSL/TCP/IP. It is composed of a part to listening of possible requests, the server, and of one or more customers. Pure Java program.

Project Naranja will uses Padlock Security of VIA EPIA mini-ITX motherboards in order to provide a toolkit to set up and use encrypted filesystems with Linux. NOTE: Files are now hosted at Google Code: http://code.google.com/p/naranja/

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

Password manager is a software that helps a user organize passwords. PwdManager is a free, open source password manager for home users. Good password management is essential to stay safe, on and offline. These days, services and programs are so many and varied that keeping track of your passwords across devices, websites and apps can be near-on impossible. That's where a password manager like PwdManager comes into play.

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.

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.
