    aria2

    aria2

    aria2 is a lightweight multi-protocol & multi-source download utility

    aria2 is a lightweight multi-protocol & multi-source command-line download utility. It supports HTTP/HTTPS, FTP, SFTP, BitTorrent and Metalink. aria2 can be manipulated via built-in JSON-RPC and XML-RPC interfaces. aria2 can download a file from multiple sources/protocols and tries to utilize your maximum download bandwidth. Really speeds up your download experience. aria2 doesn’t require much memory and CPU time. When disk cache is off, the physical memory usage is typically 4MiB (normal HTTP/FTP downloads) to 9MiB (BitTorrent downloads). CPU usage in BitTorrent with a download speed of 2.8MiB/sec is around 6%. aria2 supports The Metalink Download Description Format (aka Metalink v4), Metalink version 3, and Metalink/HTTP. Metalink offers the file verification, HTTP/FTP/SFTP/BitTorrent integration and various configurations for language, location, OS, etc.

    UBoat HTTP

    UBoat HTTP

    HTTP Botnet

    A proof-of-concept HTTP Botnet designed to replicate a full weaponized commercial botnet. This project should be used for authorized testing or educational purposes only. The main objective behind creating this offensive project was to aid security researchers and to enhance the understanding of commercial HTTP loader-style botnets. We hope this project helps to contribute to the malware research community and that people can develop efficient countermeasures. Written in C++ with no dependencies. Encrypted C&C communications. Persistence to prevent your control from being lost. Connection redundancy (Uses a fallback server address or domain). DDoS methods (TCP & UDP Flood). Task Creation System (Altering system HWID, Country, IP, OS.System). Remote command execution. Update and uninstall other malware. Download and execute other malware. Active as well as a passive key-logger. Enable Windows RDP. Plugin system for easy feature updates.

    cpprestsdk

    cpprestsdk

    Microsoft project for cloud-based client-server communication

    The C++ REST SDK is a Microsoft project for cloud-based client-server communication in native code using a modern asynchronous C++ API design. This project aims to help C++ developers connect to and interact with services. cpprestsdk is in maintenance mode and we do not recommend its use in new projects. We will continue to fix critical bugs and address security issues. Once you have the library, look at our tutorial to use the http_client. It walks through how to setup a project to use the C++ Rest SDK and make a basic Http request. HTTP client/server, JSON, URI, asynchronous streams, WebSockets client, oAuth. A powerful model for composing asynchronous operations based on C++ 11 features. Windows desktop, Windows Store (UWP), Linux, OS X, Unix, iOS, and Android. Support for Visual Studio 2015 and 2017 with debugger visualizers.

    RESTinio

    RESTinio

    HTTP/WebSocket server C++14 library

    RESTinio is a header-only C++14 library that gives you an embedded HTTP/WebSocket server. It is based on the standalone version of ASIO and is targeted primarily for the asynchronous processing of HTTP requests. Since v.0.4.1 Boost::ASIO (1.66 or higher) is also supported. Consider the task of writing a C++ application that must support some REST API, RESTinio represents our solution for that task. Server runs on the main thread, and responds to all requests with a hello-world message. Of course, you've got access to the structure of a given HTTP request, so you can apply complex logic for handling requests. Async request handling. Cannot get the response data immediately? That's ok, store the request handle somewhere and/or pass it to another execution context and get back to it when the data is ready.

    TinyGSM

    TinyGSM

    A small Arduino library for GSM modules, that just works

    A small Arduino library for GSM modules that just works. This library is easy to integrate with lots of sketches that use Ethernet or WiFi. PubSubClient (MQTT), Blynk, HTTP Client, and File Download examples are provided. Arduino GSM library uses 15868 bytes (49%) of Flash and 1113 bytes (54%) of RAM in a similar scenario. TinyGSM also pulls data gently from the modem (whenever possible), so it can operate on very little RAM. Now, you have more space for your experiments. TCP (HTTP, MQTT, Blynk, ...) All modules support TCP connections. Most modules support multiple simultaneous connections. TCP and SSL connections can usually be mixed up to the total number of possible connections. Many GSM modems, WiFi, and radio modules can be controlled by sending AT commands over Serial. TinyGSM knows which commands to send, and how to handle AT responses, and wraps that into the standard Arduino Client interface.
