    OWASP Juice Shop

    OWASP Juice Shop

    Probably the most modern and sophisticated insecure web application

    OWASP Juice Shop is probably the most modern and sophisticated insecure web application! It can be used in security trainings, awareness demos, CTFs and as a guinea pig for security tools! Juice Shop encompasses vulnerabilities from the entire OWASP Top Ten along with many other security flaws found in real-world applications! Juice Shop is written in Node.js, Express and Angular. It was the first application written entirely in JavaScript listed in the OWASP VWA Directory. The application contains a vast number of hacking challenges of varying difficulty where the user is supposed to exploit the underlying vulnerabilities. The hacking progress is tracked on a score board. Finding this score board is actually one of the (easy) challenges! Apart from the hacker and awareness training use case, pentesting proxies or security scanners can use Juice Shop as a "guinea pig"-application to check how well their tools cope with JavaScript-heavy application frontends and REST APIs.

    shadowsocks-libev

    shadowsocks-libev

    Bug-fix-only libev port of shadowsocks

    Shadowsocks-libev is a lightweight secured SOCKS5 proxy for embedded devices and low-end boxes. Shadowsocks-libev is written in pure C and depends on libev. It's designed to be a lightweight implementation of shadowsocks protocol, in order to keep the resource usage as low as possible. Snap is the recommended way to install the latest binaries. 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.

    Testing TLS/SSL encryption anywhere on any port

    testssl.sh is a free command-line tool that checks a server's service on any port for the support of TLS/SSL ciphers, protocols as well as recent cryptographic flaws and more. testssl.sh is free and open-source software. You can use it under the terms of GPLv2, please review the License before using it. Works for Linux, Mac OSX, FreeBSD, NetBSD and WSL/MSYS2/Cygwin out of the box, no need to install or configure something, no gems, CPAN, pip or the like. OpenBSD only needs bash to be postinstalled. You can test any SSL/TLS enabled and STARTTLS service, not only webservers at port 443. 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.

    Awesome Privacy

    Awesome Privacy

    A curated list of privacy & security-focused software and services

    Awesome Privacy is a curated directory of privacy-respecting alternatives to mainstream apps and services, organized across many categories like browsers, search, email, messaging, cloud storage, and operating systems. It aims to help you choose tools that reduce tracking, fingerprinting, and data collection without sacrificing usability. Each entry highlights the project’s core properties—such as open source status, end-to-end encryption, and platform availability—so you can evaluate trade-offs quickly. Because product landscapes change fast, the list emphasizes ongoing maintenance and community discussion around quality and trust. It’s useful for privacy newcomers planning a gradual migration as well as experts building a hardened toolchain. The project also surfaces learning resources and practical guidance so you can understand the broader privacy landscape, not just pick tools in isolation.
