cli - A zero trust swiss army knife for working with X509, OAuth, JWT, OATH OTP, etc.

•    Go

---

step is a zero trust swiss army knife. It’s an easy-to-use and hard-to-misuse utility for building, operating, and automating systems that use zero trust technologies like authenticated encryption (X.509, TLS), single sign-on (OAuth OIDC, SAML), multi-factor authentication (OATH OTP, FIDO U2F), encryption mechanisms (JSON Web Encryption, NaCl), and verifiable claims (JWT, SAML assertions). For more information and docs see the step website and the blog post announcing step.

django-two-factor-auth - Complete Two-Factor Authentication for Django providing the easiest integration into most Django projects

•    Python

---

Complete Two-Factor Authentication for Django. Built on top of the one-time password framework django-otp and Django's built-in authentication framework django.contrib.auth for providing the easiest integration into most Django projects. Inspired by the user experience of Google's Two-Step Authentication, allowing users to authenticate through call, text messages (SMS), by using a token generator app like Google Authenticator or a YubiKey hardware token generator (optional). I would love to hear your feedback on this package. If you run into problems, please file an issue on GitHub, or contribute to the project by forking the repository and sending some pull requests. The package is translated into English, Dutch and other languages. Please contribute your own language using Transifex.

SSH.NET - SSH.NET is a Secure Shell (SSH) library for .NET, optimized for parallelism.

•    CSharp

---

SSH.NET is a Secure Shell (SSH-2) library for .NET, optimized for parallelism.This project was inspired by Sharp.SSH library which was ported from java and it seems like was not supported for quite some time. This library is a complete rewrite, without any third party dependencies, using parallelism to achieve the best performance possible.

KeyBox - Web-based SSH console that centrally manages administrative access to systems

•    Java

---

KeyBox is an open-source web-based SSH console that centrally manages administrative access to systems. Web-based administration is combined with management and distribution of user's public SSH keys. Key management and administration is based on profiles assigned to defined users. KeyBox layers TLS/SSL on top of SSH and acts as a bastion host for administration. Protocols are stacked (TLS/SSL + SSH) so infrastructure cannot be exposed through tunneling / port forwarding.

SoftU2F - Software U2F authenticator for macOS

•    Swift

---

Soft U2F is a software U2F authenticator for OS X. It emulates a hardware U2F HID device and performs cryptographic operations using the OS X Keychain. This tool works with Google Chrome and Opera's built-in U2F implementations as well as with the U2F extensions for OS X Safari and Firefox.We take the security of this project seriously. Report any security vulnerabilities to the GitHub Bug Bounty Program.

bastion-firewall is a Netfilter based firewall for Linux. It can generate graphical stats of all the rules traffic in the firewall with Rrdtool and it's integrated with the Snort Inline IPS. It's written in the bash and C programming languages.

u2f-ref-code - U2F reference implementations

•    Javascript

---

This code can verify U2F registrations and signatures. A web application built to accept U2F 2nd factor is built on top of a code base such as this. The code base includes a trivial web application so the user can experiment with registration and signatures (also see the sample web app below).This is a Java implementation of a U2F device. It generates registration and signature statements and is meant for testing against your server implementation. A physical U2F device will generate similar statements.

TwoFactorAuth - PHP library for Two Factor Authentication (TFA / 2FA)

•    PHP

---

PHP library for two-factor (or multi-factor) authentication using TOTP and QR-codes. Inspired by, based on but most importantly an improvement on 'PHPGangsta/GoogleAuthenticator'. There's a .Net implementation of this library as well. Here are some code snippets that should help you get started...

fail2ban - Daemon to ban hosts that cause multiple authentication errors

•    Python

---

Fail2Ban scans log files like /var/log/auth.log and bans IP addresses having too many failed login attempts. It does this by updating system firewall rules to reject new connections from those IP addresses, for a configurable amount of time. Fail2Ban comes out-of-the-box ready to read many standard log files, such as those for sshd and Apache, and is easy to configure to read any log file you choose, for any error you choose. Though Fail2Ban is able to reduce the rate of incorrect authentications attempts, it cannot eliminate the risk that weak authentication presents. Configure services to use only two factor or public/private authentication mechanisms if you really want to protect services.
