    Cloudflare-Socks5

    Cloudflare-Socks5

    CF-workers/pages proxy script: supports Vless-ws (tls) and Trojan-ws

    ...The project provides scripts that enable users to deploy proxy services locally without relying on external subscription providers, improving privacy and control over configuration data. It supports multiple transport modes including WebSocket with TLS, as well as optional encrypted handshake mechanisms like ECH-TLS, standard TLS, or even non-TLS configurations to adapt to different network restrictions. The system is designed with accessibility in mind, offering simplified setup processes that allow users to deploy nodes with minimal configuration, often requiring only a UUID or password. ...

    InterceptSuite

    InterceptSuite

    A TLS MITM proxy for Non-HTTP traffic, with support for TLS upgrades

    InterceptSuite is a cross‑platform, SOCKS5‑based MITM proxy specially designed to intercept, inspect, analyze, and manipulate encrypted network traffic at the TCP/TLS layer. It goes beyond HTTP‑focused tools like Burp Suite and ZAP by providing universal TLS interception—including STARTTLS and non‑HTTP protocols—offering deep visibility and control for security testing and debugging. InterceptSuite bridges this gap by providing a universal TLS interception engine that works with any protocol, giving security researchers the tools they need to analyze, understand, and test encrypted communications effectively. ...

    V2Ray

    V2Ray

    Shell script that aims to make installing and managing V2Ray

    ...The script includes a menu-driven manager to modify ports, protocols, and users, restart the service, or view logs without hand-editing configuration files. It supports widely used transport options like TCP and WebSocket and can be paired with a reverse proxy for TLS termination, allowing cleaner integration with standard web servers. Designed for pragmatism over pedagogy, the tool focuses on getting a working, maintainable V2Ray server online in minutes rather than requiring deep familiarity with every configuration knob.

    Client for PPP+TLS VPN tunnel services

    openfortivpn is a command-line SSL VPN client for connecting to Fortinet FortiGate gateways without relying on proprietary GUIs. It negotiates the SSL/TLS tunnel, authenticates with credentials (and commonly with two-factor methods), then brings up a secure point-to-point interface and installs routes and DNS settings. The tool aims to be minimal and dependable: a single binary with an INI-style config file, systemd compatibility, and clear runtime diagnostics. It handles details like MTU tuning, split tunneling via pushed routes, and reconnect logic to keep the session stable. ...

    s2n-quic

    s2n-quic

    An implementation of the IETF QUIC protocol

    ...QUIC is a UDP-based, multiplexed, encrypted transport layer that underpins HTTP/3 and addresses issues such as head-of-line blocking and faster handshake times compared to TCP+TLS. This library integrates with AWS’s s2n-tls or rustls for the TLS 1.3 handshake and leverages Rust’s memory and thread safety guarantees to deliver a robust implementation. It is built with configurability in mind—you can tune congestion control (like CUBIC), pacing, packet size discovery, and other advanced network behaviors. Extensive testing (unit, fuzz, interop) ensures protocol compliance and interoperability with other implementations. ...

    A ssh server that knows who you are. $ ssh whoami.filippo.io

    whoami.filippo.io powers a diagnostic service that reports what your client and connection look like from the other side, making it a handy mirror for network and TLS debugging. It surfaces details such as your IP address, protocol versions, cipher suites, SNI, and other attributes that are otherwise tedious to confirm across layers. The tool emphasizes clarity and minimalism, helping engineers quickly verify configuration changes in browsers, proxies, VPNs, or CLI tools. It is especially helpful when validating modern TLS features like ALPN, HTTP versions, and certificate behavior under different client stacks. ...

    rnet

    rnet

    Python HTTP client with TLS and HTTP/2 fingerprint emulation support

    ...It provides a flexible API for making HTTP requests while supporting both asynchronous and blocking workflows, allowing it to integrate easily into different Python applications and runtimes. rnet focuses on low-level protocol customization, giving users fine-grained control over TLS and HTTP/2 configuration in order to emulate specific browser behaviors. This includes support for TLS fingerprinting techniques such as JA3 and JA4 as well as detailed HTTP/2 settings, enabling more accurate simulation of real client network traffic. It is powered by the underlying wreq engine and is built with performance and modularity in mind. rnet also supports advanced networking capabilities such as proxy rotation, connection pooling, and streaming transfers, which make it suitable for automation, scraping, and high-performance network.

    Powerful and flexible HTTP reverse proxy

    ...It implements an entirely new and interesting approach of handling browser-based HTTP traffic flow, which allows to transparently proxy of multi-domain destination traffic, both TLS and non-TLS, over a single domain, without the requirement of installing any additional certificate on the client. What exactly does this mean? In short, it simply has a lot of potential, that can be used in many use case scenarios. Modlishka was written as an attempt to overcome standard reverse proxy limitations and as a personal challenge to see what is possible with sufficient motivation and a bit of extra research time. ...
