    Gobuster

    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.

    passport-facebook

    passport-facebook

    Facebook authentication strategy for Passport and Node.js.

    passport-facebook is a Passport strategy for authenticating users with their Facebook credentials using the OAuth 2.0 protocol, enabling Node.js applications to let visitors log in with their Facebook account easily. It manages the redirection to Facebook’s login page, the authorization code exchange, and the retrieval of basic profile information, reducing the boilerplate developers would otherwise write to integrate with Facebook’s API manually. When used with Express and Passport, the strategy triggers redirects and callback handling automatically based on configured routes, so developers can focus on application logic like user onboarding and account linkage. The module normalizes the returned user profile into a consistent format so you can store or use profile data with minimal translation. It also handles secure token exchange and sanitization of inputs to protect against common OAuth attacks.

    Google Auth Library

    Google Auth Library

    Google Auth Library for Node.js

    This is Google's officially supported node.js client library for using OAuth 2.0 authorization and authentication with Google APIs. Use Application Default Credentials when you use a single identity for all users in your application. Especially useful for applications running on Google Cloud. Application Default Credentials also support workload identity federation to access Google Cloud resources from non-Google Cloud platforms. Use JWT when you are using a single identity for all users. Especially useful for server->server or server->API communication. Use workload identity federation to access Google Cloud resources from Amazon Web Services (AWS), Microsoft Azure or any identity provider that supports OpenID Connect (OIDC). Use workforce identity federation to access Google Cloud resources using an external identity provider (IdP) to authenticate and authorize a workforce—a group of users, such as employees, partners, and contractors.
