Google APIs Node.js Client
Google's supported Node.js client library
Google's supported Node.js client library for accessing Google APIs. Support for authorization and authentication with OAuth 2.0, API Keys and JWT (Service Tokens) is included. The full list of supported APIs can be found on the Google APIs Explorer. The API endpoints are automatically generated, so if the API is not in the list, it is currently not supported by this API client library. These client libraries are supported by Google. However, these libraries are considered complete and are in maintenance mode. This means that we will address critical bugs and security issues but will not add any new features. For Google Cloud Platform APIs, we recommend using google-cloud-node which is under active development. This library supports the maintenance LTS, active LTS, and current release of node.js. -

Google Authenticator OpenSource
Open source version of Google Authenticator (except the Android app)
Google Authenticator is the open-source counterpart of Google’s one-time passcode apps, implementing industry-standard OATH algorithms such as TOTP (time-based) and HOTP (counter-based) for two-factor authentication. The repository historically hosts code for mobile platforms like iOS and BlackBerry, demonstrating how to generate numeric codes locally without needing network access. Its core purpose is to help services and users add a second factor that’s simple to deploy yet resistant to password reuse and phishing. The app flow revolves around enrolling secrets via QR codes or manual entry, storing them securely on-device, and rendering rotating codes synchronized by time. Because it uses open standards, it interoperates with virtually any service that supports TOTP/HOTP, not just Google properties. The project also serves as a reference for implementers who want to understand enrollment UX, secret provisioning, and code generation at the application layer. -

OmniAuth
OmniAuth is a flexible authentication system utilizing Rack middleware
OmniAuth is a library that standardizes multi-provider authentication for web applications. It was created to be powerful, flexible, and do as little as possible. Any developer can create strategies for OmniAuth that can authenticate users via disparate systems. OmniAuth strategies have been created for everything from Facebook to LDAP. In order to use OmniAuth in your applications, you will need to leverage one or more strategies. These strategies are generally released individually as RubyGems, and you can see a community-maintained list on the wiki for this project. One strategy, called Developer, is included with OmniAuth and provides a completely insecure, non-production-usable strategy that directly prompts a user for authentication information and then passes it straight through. You can use it as a placeholder when you start development and easily swap in other strategies later. -

Sobelow
Security-focused static analysis for the Phoenix Framework
Sobelow is a security-focused static analysis tool for the Phoenix framework. For security researchers, it is a useful tool for getting a quick view of points-of-interest. For project maintainers, it can be used to prevent the introduction of a number of common vulnerabilities. Potential vulnerabilities are flagged in different colors according to confidence in their insecurity. High confidence is red, medium confidence is yellow, and low confidence is green. A finding is typically marked "low confidence" if it looks like a function could be used insecurely, but it cannot reliably be determined if the function accepts user-supplied input. That is to say, if a finding is marked green, it may be critically insecure, but it will require greater manual validation. This project is in constant development, and additional vulnerabilities will be flagged as time goes on. If you encounter a bug, or would like to request additional features or security checks, please open an issue! -

Sureness
A simple and efficient security framework
Sureness allows you to security any server written with jvm modern frameworks such as Spring, Spring Boot, Spring WebFlux, Javalin, Quarkus, Micronaut, Solon, Jfinal or Ktor as well as frameworks for Kotlin. The essence of Sureness is to use an interceptor (like a servlet filter or Spring interceptor) to intercept all rest requests for authenticating and authorizing. So no matter any framework, as long as it has an interceptor, it can integrate with sureness. Sureness uses Exception Handling Process, checkIn() will return SubjectSum(user information) when auth success, or throw different types of auth exceptions when auth error. Sureness has a sensible default configuration, is easy to customize, and is not coupled to any one framework, which enables developers to quickly and safely protect their projects in multiple scenarios. -

Tomb
the Crypto Undertaker
Tomb is a minimalistic command-line tool for creating and managing encrypted “tombs,” which are files that act as mountable, private storage vaults. Under the hood it uses Linux dm-crypt with LUKS for strong, disk-level encryption, and separates the key material from the vault itself to improve security workflows. Keys can be protected with passphrases and even hidden via steganography inside innocuous files, giving you options for concealment and off-device storage. The interface is deliberately simple—dig a tomb, forge a key, lock it, and open it—yet provides hooks to bind directories or run scripts on open/close so you can tailor behavior to your workstation. Permissions and ownership hygiene are emphasized to avoid leaking metadata, and the tool favors auditable shell operations that experienced users can inspect. Tomb’s model suits people who want encrypted containers with Unix-friendly ergonomics, keeping secrets safe while integrating cleanly into everyday scripts and workflows.
