Gobuster
Directory/File, DNS and VHost busting tool written in Go
Gobuster is a tool used to brute-force. This project is born out of the necessity to have something that didn't have a fat Java GUI (console FTW), something that did not do recursive brute force, something that allowed me to brute force folders and multiple extensions at once, something that compiled to native on multiple platforms, something that was faster than an interpreted script (such as Python), and something that didn't require a runtime. Provides several modes, like the classic directory brute-forcing mode, DNS subdomain brute-forcing mode, the mode that enumerates open S3 buckets and looks for existence and bucket listings, and the virtual host brute-forcing mode (not the same as DNS!). Since this tool is written in Go you need to install the Go language/compiler/etc. Full details of installation and set up can be found on the Go language website. Once installed you have two options. You need at least go 1.16.0 to compile gobuster. -

Authelia is an open-source authentication and authorization server and portal fulfilling the identity and access management (IAM) role of information security in providing multi-factor authentication and single sign-on (SSO) for your applications via a web portal. It acts as a companion for common reverse proxies. With a compressed container size smaller than 20 megabytes and observed memory usage normally under 30 megabytes, it's one of the most lightweight solutions available. Written in Go and React, authorization policies and many other backend tasks are completed in mere milliseconds and login portal loading times of 100 milliseconds makes it one of the fastest solutions available. Processors can use a lot of electricity, but when idle usage is basically so low that you can't measure it, and active usage in a small business environment being under 1% you can rest easy (with the exclusion of password hashing). -

Comeonin
Password hashing specification for the Elixir programming language
Comeonin is the long-standing password-security library for Elixir that standardizes secure hashing and verification practices in Phoenix and Plug applications. It provides a uniform interface for modern algorithms such as Argon2, Bcrypt, and PBKDF2 (implemented in companion packages), along with guidance for salts, cost factors, and timing-safe comparisons. The library’s helpers make it straightforward to add registration and login flows that resist brute-force and side-channel attacks. Migration paths and checks are included so you can upgrade algorithms or work factors over time without breaking existing credentials. Its focus on practical ergonomics—clear APIs, sensible defaults, and good docs—has made it the de facto choice for password handling in Elixir. By centralizing hashing concerns, Comeonin helps teams avoid subtle security mistakes while keeping authentication code terse and testable. -
