GnuTLS
Mirror of official gnutls repository
GnuTLS is an open-source secure communications library designed to implement cryptographic protocols such as TLS, SSL, and DTLS for protecting data transmitted over networks. Developed as part of the GNU Project, it provides a robust framework for building secure client-server applications and services that require encrypted communication channels. The library includes implementations of widely used security standards and supports modern encryption algorithms, authentication mechanisms, and certificate management features. GnuTLS is frequently used in network servers, email systems, VPNs, and embedded systems where developers need reliable and standards-compliant TLS functionality. Because it is distributed as a programmable library rather than a standalone application, it integrates directly into software that needs secure network connections. The project emphasizes open standards and interoperability while remaining flexible enough to support various platforms and architectures. -

GoPass
GoPass uses moves in a game of go to generate a password.
GoPass is a password generator. Its function is similar to random password generators, but the generation method is very different. This program generates passwords based on opening moves in a go game. The method is simple: the Custom Seed at the bottom is used to seed a random number generator (RNG). The RNG assigns a value to every intersection on the board. After moves are played, and Make Password pressed, the values of the intersections generate a password based on the game. All of this is done locally. No information is sent outside of the program. Because go players can remember game moves so well (the information is meaningful), it allows them to use unique passwords for different websites without having to memorize strange strings of symbols (which are meaningless). How strong are the passwords? The complexity is 361 * 360 * 359 ... n times where "n" is the number of moves. So after 8 or so moves, they are pretty strong. And when put with the seed, it is very strong. -

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 PAM Library
Example PAM module demonstrating two-factor authentication
google-authenticator-libpam is a Pluggable Authentication Module (PAM) that adds one-time passcodes to Unix and Linux logins using open OATH standards. It plugs into PAM stacks for services like SSH, su, or desktop display managers, prompting users for a time-based (TOTP) or counter-based (HOTP) code after their password. A lightweight enrollment program bootstraps each account by generating a secret, printing a QR code, and writing per-user configuration with safe file permissions. Because verification happens locally, codes work offline and do not depend on any Google service, which suits high-security and air-gapped environments. Administrators can tune skew tolerance, rate limiting, emergency scratch codes, and which PAM control flags enforce 2FA for specific users or groups. The project’s design favors simplicity and auditability, keeping the runtime small and the configuration explicit so it’s easy to review in production change control. -

GopenPGP V3
A high-level OpenPGP library
GopenPGP V3 is a high-level OpenPGP cryptographic library developed by ProtonMail that provides a user-friendly API for common encryption and signing operations in Go, abstracting the complexity of the underlying OpenPGP standards and golang crypto primitives. This library lets developers perform key generation, message encryption and decryption, digital signing, and signature verification with straightforward functions that hide much of the boilerplate and nuance typically required when working directly with OpenPGP implementations. Built on top of a forked version of the Go crypto library, gopenpgp supports current OpenPGP RFC standards and includes examples for working with password-based encryption and PGP keys, as well as detached and inline signatures. Because it’s designed for broad use, the library also targets go-mobile compatibility, meaning it can support mobile app use cases alongside server and desktop tooling. -

Gouq.gq Saveword
Handy password manager and generator
Gouq.gq Saveword saves all of your Passwords, so you are always able to look after them if you forgot one of them. Besides that, it gives you the ability to generate random passwords which are much safer than password made out of words.

Gradle Test Logger Plugin
A Gradle plugin for printing beautiful logs on the console
A Gradle plugin for printing beautiful logs on the console while running tests. The plugin registers an extension called testlogger (all lowercase and one word) at project level as well as for each task of type Test. By default, the showExceptions flag is turned on. This shows why the tests failed including the location of the failure. Of course, you can switch off this slightly more verbose logging by setting showExceptions to false. Just like Gradle itself, by default only the last frame that matches the test class's name in a stack trace is printed. For vast majority of cases, that is sufficient. Sometimes, it is useful to remove this filtering in order to see the entirety of the stack trace. -

Guardian
Elixir Authentication
Guardian is a token based authentication library for use with Elixir applications. Guardian remains a functional system. It integrates with Plug but can be used outside of it. If you're implementing a TCP/UDP protocol directly or want to utilize your authentication via channels in Phoenix, Guardian can work for you. The core currency of authentication in Guardian is the token. By default JSON Web Tokens are supported out of the box but you can use any token that Has the concept of a key-value payload, is tamper-proof, can serialize to a String, or that has a supporting module that implements the Guardian.Token behavior. You can use Guardian tokens to authenticate web endpoints (Plug/Phoenix/X), channels/Sockets (Phoenix - optional), and any other system you can imagine. If you can attach an authentication token you can authenticate it. -
