Shadowsocks for Windows
A secure socks5 proxy for Windows
Shadowsocks for Windows is a free and open source, high-performance secured socks5 proxy designed to protect your internet traffic. It allows you to surf the web privately and securely, and offers a number of useful features such as HTTP proxy support, system proxy configuration, server auto switching and plugin support. Shadowsocks is incredibly fast, as it utilizes bleeding edge techniques with Asynchronous I/O and event-driven programming. It also has a flexible industry-level encryption algorithm that supports custom algorithms. Shadowsocks for Windows requires a Microsoft .NET Framework 4.7.2 or higher, as well as Microsoft Visual C++ 2015 Redistributable (x86). -

Advanced Onion Router is a portable client for the OR network and is intended to be an improved alternative for Tor+Vidalia+Privoxy bundle for Windows users. Some of the improvements include UNICODE paths, support for HTTP and HTTPS proxy protocols on the same Socks4/Socks5 port with HTTP header filtering that generates fake identity-dependent headers every time the identity is changed (proxy chains are also supported), support for NTLM proxies, a User Interface that makes Tor's options and actions more accessible, local banlist for forbidden addresses, private identity isolation, a point-and-click process interceptor that can redirect connections from programs that don't support proxies, also giving them fake information about the local system and support for .onion addresses. Also, it can estimate AS paths for all circuits and prevent AS path intersections, it can restrict circuits to be built using only nodes from different countries, can change circuit lengths and more.

shadowsocks-libev
Bug-fix-only libev port of shadowsocks
Shadowsocks-libev is a lightweight secured SOCKS5 proxy for embedded devices and low-end boxes. Shadowsocks-libev is written in pure C and depends on libev. It's designed to be a lightweight implementation of shadowsocks protocol, in order to keep the resource usage as low as possible. Snap is the recommended way to install the latest binaries. You can build shadowsocks-libev and all its dependencies by script. The latest shadowsocks-libev has provided a redir mode. You can configure your Linux-based box or router to proxy all TCP traffic transparently, which is handy if you use an OpenWRT-powered router. Although shadowsocks-libev can handle thousands of concurrent connections nicely, we still recommend setting up your server's firewall rules to limit connections from each user. We strongly encourage you to install shadowsocks-libev from jessie-backports-sloppy. -

A pronounceable password generator plugin for KeePass. NOTE: This project has been discontinued. It hasn't been worth it to maintain the project for a while now, so no more updates will be made to the plugin. The algorithm this plugin uses is based off FIPS-181 which was withdrawn by NIST a while back. The proliferation of password managers that seamlessly run on multiple platforms (some of which are free) has also removed almost all advantages of using randomly generated pronounceable passwords. If you have a use case for this plugin, reconsider it. If you still think using randomly generated pronounceable passwords are worth it for your use case, reconsider it some more.

AWS Encryption SDK for Java
AWS Encryption SDK
The AWS Encryption SDK is a client-side encryption library designed to make it easy for everyone to encrypt and decrypt data using industry standards and best practices. It enables you to focus on the core functionality of your application, rather than on how to best encrypt and decrypt your data. The AWS Encryption SDK is provided free of charge under the Apache 2.0 license. With the AWS Encryption SDK, you define a master key provider (Java and Python) or a keyring (C, C#/.NET, and JavaScript) that determines which wrapping keys you use to protect your data. Then you encrypt and decrypt your data using straightforward methods provided by the AWS Encryption SDK. The AWS Encryption SDK does the rest. Without the AWS Encryption SDK, you might spend more effort on building an encryption solution than on the core functionality of your application. By default, the AWS Encryption SDK generates a unique data key for each data object that it encrypts. -

openSSLGOSTSigner
Simple GUI tool for openssl to sign files with GOST algorithm
This software is a simple GUI tool which uses openssl command line utility underneath. It designed to sign any type of files with GOST algorithm (GOST cipher) and will be especially useful for russian ISP's and IT companies which in one way or another have to deal with Roskomnadzor's forbidden sites list to reduce the timewaste while typing in commandline each time you need to sign some file. To use this software you will need to have a ".PEM" file(which exactly used to sign files). If you have your ".PEM" file already - nothing else will be needed. But you can easily make one within this utility. All you need to do this - is a ".PFX"(p12) file. In the openssl folder you'll find an x86 and x64 installation packets of openssl commandline utility which are HIGHLY recommended to use, 'cause this utility was created and tested exactly with those versions of openssl. -

NTK Ultra-Compression
Logiciel de compression de fichiers maximal indépendant du temps.
Le logiciel NTK Ultra-Compression répond à une problématique essentielle de l’ère numérique : comment réduire la taille des données à leur minimum absolu sans compromis sur leur intégrité, tout en s’affranchissant des contraintes temporelles ? Dans un monde où les volumes de données explosent et où les solutions actuelles de compression restent limitées par des compromis entre rapidité, efficacité et complexité, nous proposons une approche disruptive. Les solutions actuelles, telles que le format ZIP ou 7z, bien qu’efficaces, atteignent leurs limites en termes de taux de compression et d’efficacité pour les fichiers volumineux ou complexes. Ces outils sont souvent contraints par des compromis entre rapidité d’exécution et efficacité de stockage. Cette approche disruptive s’adresse notamment aux utilisateurs ayant besoin de manipuler des fichiers volumineux, comme les logiciels, les jeux vidéo ou les bases de données, où chaque octet économisé compte. -

PureBasic Shamir Secret Sharing
Open-source PureBasic implementation of the Shamir Secret Sharing
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
