    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. ...

    Ghostunnel

    Ghostunnel

    A simple SSL/TLS proxy with mutual authentication

    ...Ghostunnel in server mode runs in front of a backend server and accepts TLS-secured connections, which are then proxied to the (insecure) backend. A backend can be a TCP domain/port or a UNIX domain socket. Ghostunnel in client mode accepts (insecure) connections through a TCP or UNIX domain socket and proxies them to a TLS-secured service. In other words, ghostunnel is a replacement for stunnel. Ghostunnel is developed primarily for Linux and Darwin (macOS), although it should run on any UNIX system that exposes SO_REUSEPORT, including FreeBSD, OpenBSD and NetBSD. ...

    Ligolo-ng

    Ligolo-ng

    An advanced, yet simple, tunneling/pivoting tool

    Ligolo-ng is a simple, lightweight and fast tool that allows pentesters to establish tunnels from a reverse TCP/TLS connection using a tun interface (without the need of SOCKS). When running the relay/proxy server, a tun interface is used, packets sent to this interface are translated and then transmitted to the agent's remote network. You need to download the Wintun driver (used by WireGuard) and place the wintun.dll in the same folder as Ligolo.

    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. ...

    Bug-fix-only libev port of shadowsocks

    ...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.
