    MTProxy

    MTProxy

    Simple MT-Proto proxy

    MTProxy is Telegram’s official MTProto proxy server implementation that enables users to create and run proxy nodes for the Telegram messaging platform, helping people connect securely and reliably when direct access to Telegram is restricted or blocked. It implements the MTProto proxy protocol, which obfuscates encrypted Telegram traffic so it appears indistinguishable from normal HTTPS/TLS flows, making it harder for ISPs or authorities to detect and block Telegram traffic based on signatures. The repository includes C source code, build instructions, and configuration files for compiling and running the proxy on Unix-like systems, with dependencies including OpenSSL and zlib. By launching an MTProxy instance with a secret and configuration file, system administrators can allow clients to connect through custom proxies and generate shareable proxy links for Telegram clients.

    CMake

    CMake

    Cross-platform tool to build, test and package software

    CMake is an open-source, cross-platform family of tools designed to build, test and package software. CMake is used to control the software compilation process using simple platform and compiler independent configuration files, and generate native makefiles and workspaces that can be used in the compiler environment of your choice. The suite of CMake tools were created by Kitware in response to the need for a powerful, cross-platform build environment for open-source projects such as ITK and VTK. CMake is part of Kitware’s collection of commercially supported open-source platforms for software development and integrates with CDash to provide a comprehensive suite of tools. CDash is the testing server that aggregates, analyzes, and displays the results of software testing processes submitted from clients located around the world.

    PyInstaller

    PyInstaller

    Converts (packages) Python programs into stand-alone executables

    PyInstaller is a program that converts (packages) Python programs into stand-alone executables, under Windows, Linux, Mac OS X, AIX and Solaris. Its main advantages over similar tools are that PyInstaller works with any version of Python since 2.3, it builds smaller executables thanks to transparent compression, it is fully multi-platform, and uses the OS support to load the dynamic libraries, thus ensuring full compatibility. The main goal of PyInstaller is to be compatible with 3rd-party packages out-of-the-box. This means that, with PyInstaller, all the required tricks to make external packages work are already integrated within PyInstaller itself so that there is no user intervention required. You'll never be required to look for tricks in wikis and apply custom modification to your files or your setup scripts. As an example, libraries like PyQt, Django or matplotlib are fully supported, without having to handle plugins or external data files manually.

    libgit2

    libgit2

    A cross-platform, portable, linkable Git implementation library

    libgit2 is a portable, pure C implementation of the Git core methods provided as a re-entrant linkable library with a solid API, allowing you to write native speed custom Git applications in any language which supports C bindings. Libgit2 is developed with CMake, and this is be the easiest way to build a binary from the source. The CMake build system provides lots of options to configure the libgit2 build for your particular needs. It’s highly recommended that you build libgit2 as a static library for Xcode projects to simplify distribution significantly. libgit2 is used for powering Git GUI clients, such as gmaster and GitKraken and on Git hosting providers such as GitLab, Azure, GitHub, DevOps, among others. By clicking "merge pull request", we perform the merge. It is licensed under the GPLv2 license, so you can link it in its unmodified state with any type of software without releasing its source code.
