Hackingtool
ALL IN ONE Hacking Tool For Hackers
HackingTool by Z4nzu is a large collection (“all-in-one”) of tools and scripts for penetration testing / hacking / OSINT etc. It bundles many utilities (port scanners, payload injectors, web attack tools, phishing tools, wireless attack tools, reverse engineering, etc.) into a menu interface. Includes many individual tools, often wrappers or aggregations of existing well-known tools (e.g. port scanners, web attack tools, steganography, hash cracking etc.). A menu interface offering categories: reconnaissance, payload creation, wireless attacks, reverse engineering, exploit frameworks, etc. Users can pick which tool to run. It is intended more for “ethical / lab / educational” hacking contexts rather than production or stealth scenarios. It depends a lot on external tools, grants, and root privileges in many cases. -

ZAP
The OWASP ZAP core project
The OWASP Zed Attack Proxy (ZAP) is one of the world’s most popular free security tools and is actively maintained by a dedicated international team of volunteers. It can help you automatically find security vulnerabilities in your web applications while you are developing and testing your applications. It's also a great tool for experienced pentesters to use for manual security testing. ZAP is an easy to use integrated penetration testing tool for finding vulnerabilities in web applications. It is designed to be used by people with a wide range of security experience and as such is ideal for developers and functional testers who are new to penetration testing. ZAP provides automated scanners as well as a set of tools that allow you to find security vulnerabilities manually. It stands between the tester’s browser and the web application so that it can intercept and inspect messages sent between browser and web application. -

mkcert
Zero-config tool to make locally trusted development certificates
mkcert is a simple tool for making locally-trusted development certificates. It requires no configuration. Using certificates from real certificate authorities (CAs) for development can be dangerous or impossible (for hosts like example.test, localhost or 127.0.0.1), but self-signed certificates cause trust errors. Managing your own CA is the best solution, but usually involves arcane commands, specialized knowledge and manual steps. mkcert automatically creates and installs a local CA in the system root store, and generates locally-trusted certificates. mkcert does not automatically configure servers to use the certificates, though, that's up to you. The CA certificate and its key are stored in an application data folder in the user's home. You usually don't have to worry about it, as the installation is automated, but the location is printed by mkcert -CAROOT. -

OpenH264
Open Source H.264 Codec
Cisco has taken their H.264 implementation and open-sourced it under BSD license terms. Development and maintenance will be overseen by a board from the industry and the open-source community. Furthermore, we have provided a binary form suitable for inclusion in applications across a number of different operating systems and made this binary module available for download from the Internet. We will not pass on our MPEG-LA licensing costs for this module, and based on the current licensing environment, this will effectively make H.264 free for use on supported platforms. OpenH264 is a codec library which supports H.264 encoding and decoding. It is suitable for use in real-time applications such as WebRTC. Constrained Baseline Profile up to Level 5.2 (Max frame size is 36864 macro-blocks). Arbitrary resolution, not constrained to multiples of 16x16. Rate control with adaptive quantization, or constant quantization. -

SecLists
The Pentester’s Companion
SecLists is the ultimate security tester’s companion. It is a collection of various types of lists commonly used during security assessments, all in one place. SecLists helps to increase efficiency and productivity in security testing by conveniently providing all the lists a security tester may need in one repository. List types include those for usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and many more. All the tester will have to do is pull this repo onto a new testing box and he’ll have access to every type of list he may require. -

age
A simple, modern and secure encryption tool (and Go library)
age is a security-oriented tool and library by Filo Sottile. age is a simple, modern, secure encryption utility (and Go library) that emphasizes minimal configuration and strong defaults. It provides small explicit keys, no complex options, and is designed for UNIX-style composability; you can pipe into it, integrate it into scripts, etc. It supports a clearly defined format and promotes interoperability across implementations (there are Rust, TypeScript, etc). The project is well-suited for personal data encryption, backup use-cases, scripting encryption workflows, and embedding encryption in tools. Because of its design philosophy, it avoids the bloat of many older encryption utilities while maintaining strong cryptographic hygiene. It’s especially useful for developers or system administrators who want to adopt encryption without learning a multitude of options. -

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. -

Django OAuth Toolkit
OAuth2 goodies for the Djangonauts!
Django OAuth Toolkit can help you by providing, out of the box, all the endpoints, data, and logic needed to add OAuth2 capabilities to your Django projects. Django OAuth Toolkit makes extensive use of the excellent OAuthLib, so that everything is rfc-compliant. OAuth is an open standard for access delegation, commonly used as a way for Internet users to grant websites or applications access to their information on other websites but without giving them the passwords. Django is a high-level Python Web framework that encourages rapid development and clean, pragmatic design. Built by experienced developers, it takes care of much of the hassle of Web development, so you can focus on writing your app without needing to reinvent the wheel. Your Django app exposes a web API you want to protect with OAuth2 authentication. You need to implement an OAuth2 authorization server to provide tokens management for your infrastructure. -
