    s2n

    s2n

    An implementation of the TLS/SSL protocols

    ...Additionally there are no locks or mutexes within s2n-tls. s2n-tls implements SSLv3, TLS1.0, TLS1.1, TLS1.2, and TLS1.3. For encryption, s2n-tls supports 128-bit and 256-bit AES in the CBC and GCM modes, ChaCha20, 3DES, and RC4. For forward secrecy, s2n-tls supports both DHE and ECDHE. s2n-tls also supports the Server Name Indicator (SNI), Application-Layer Protocol Negotiation (ALPN), and Online Certificate Status Protocol (OCSP) TLS extensions. ...

    OpenSSL Project

    OpenSSL Project

    TLS/SSL and crypto library

    OpenSSL is a robust, commercial-grade, full-featured Open Source Toolkit for the TLS (formerly SSL), DTLS and QUIC (currently client-side only) protocols. The protocol implementations are based on a full-strength general-purpose cryptographic library, which can also be used stand-alone. Also included is a cryptographic module validated to conform with FIPS standards. OpenSSL is descended from the SSLeay library developed by Eric A.

    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 is a simple TLS proxy with mutual authentication support for securing non-TLS backend applications. Ghostunnel supports two modes, client mode and server mode. 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.

    Caddy

    Caddy

    Powerful, enterprise-ready, open source web server w/ automatic HTTPS

    Caddy is a powerful, extensible, enterprise-ready server platform that uses TLS by default. Everything you would require in your infrastructure, from TLS certificate renewals and OCSP stapling, to reverse proxying and ingress, Caddy simplifies it all.

    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.

    OpenFortiVPN

    OpenFortiVPN

    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. ...

    whoami.filippo.io

    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. ...

    CFSSL is CloudFlare's PKI/TLS swiss army knife. It is both a command line tool and an HTTP API server for signing, verifying, and bundling TLS certificates. It requires Go 1.12+ to build. Note that certain linux distributions have certain algorithms removed (RHEL-based distributions in particular), so the golang from the official repositories will not work. Users of these distributions should install go manually to install CFSSL.

Several command line options help you to run your test and configure your output. If a particular check cannot be performed because of a missing capability on your client side, you'll get a warning. You can look at the code, see what's going on and you can change it.

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. ...

    SDK for connecting to AWS IoT from a device using Python

    ...We invite your feedback! The SDK is built on top of a modified Paho MQTT Python client library. Developers can choose from two types of connections to connect to AWS IoT. For MQTT over TLS (port 8883 and port 443), a valid certificate and a private key are required for authentication. For MQTT over the WebSocket protocol (port 443), a valid AWS Identity and Access Management (IAM) access key ID and secret access key pair are required for authentication.
