git-secret - :busts_in_silhouette: A bash-tool to store your private data inside a git repository.

•    Shell

git-secret is a bash tool which stores private data inside a git repo. git-secret encrypts tracked files with public keys for users whom you trust using gpg, allowing permitted users to access encrypted data using their secret keys. With git-secret, changes to access rights are made easy and private-public key issues are handled for you. Passwords do not need to be changed with git-secret when someone's permission is revoked - just remove their key from the keychain using git secret killperson their@email.com, and re-encrypt the files, and they won't be able to decrypt secrets anymore. It also supports apt and yum. You can also use make if you want to. See the installation section for the details.

gopass - The slightly more awesome standard unix password manager for teams

•    Go

The slightly more awesome Standard Unix Password Manager for Teams. Written in Go. gopass is a rewrite of the pass password manager in Go with the aim of making it cross-platform and adding additional features. Our target audience are professional developers and sysadmins (and especially teams of those) who are well versed with a command line interface. One explicit goal for this project is to make it more approachable to non-technical users. We go by the UNIX philosophy and try to do one thing and do it well, providing a stellar user experience and a sane, simple interface.

OpenPGP.js - OpenPGP implementation for JavaScript

•    Javascript

OpenPGP.js is a JavaScript implementation of the OpenPGP protocol. It aims to provide an Open Source OpenPGP library in JavaScript so it can be used on virtually every device. This does not require gpg on their machines in order to use the library. The idea is to implement all the needed OpenPGP functionality in a JavaScript library that can be reused in other projects that provide browser extensions or server applications. It should allow you to sign, encrypt, decrypt, and verify any kind of text - in particular e-mails - as well as managing keys.

keybase-gpg-github - Step-by-step guide on how to create a GPG key on keybase

This is a step-by-step guide on how to create a GPG key on keybase.io, adding it to a local GPG setup and use it with Git and GitHub. Although this guide was written for macOS, most commands should work in other operating systems as well.

Limnoria - A modified version of Supybot (an IRC bot) with Python 3 and IRCv3 support including SASL, translations (fr/fi/it/hu/de), GPG authentication, TLS, and many other enhancements and bug fixes

•    Python

Supybot is a robust (it doesn't crash), user friendly (it's easy to configure) and programmer friendly (plugins are extremely easy to write) Python IRC bot. It aims to be an adequate replacement for most existing IRC bots. It includes a very flexible and powerful ACL system for controlling access to commands, as well as more than 50 builtin plugins providing around 400 actual commands. Limnoria is a project which continues development of Supybot (you can call it a fork) by fixing bugs and adding features.

GpgAPI - A C# Api for Gpg

•    DotNet

GpgAPI is a C# API for Gpg. Gpg is a command line software to encrypt, decrypt files with a symmetric or assymetric key. You can also manage your public keys, import public keys from the web, export your public keys to the web, etc. GpgAPI is an interface to Gpg. In C#,...

minisign - A dead simple tool to sign files and verify digital signatures.

•    C

Minisign is a dead simple tool to sign files and verify signatures. Minisign uses the EdDSA signature system, and deterministic signature schemes are fragile against fault attacks. However, conducting these requires physical access or the attacker having access to the same physical host.

trezor-agent - Hardware-based SSH/PGP agent

•    Python

This project allows you to use various hardware security devices to operate GPG and SSH. Instead of keeping your key on your computer and decrypting it with a passphrase when you want to use it, the key is generated and stored on the device and never reaches your computer. Read more about the design here. You can do things like sign your emails, git commits, and software packages, manage your passwords (with pass and gopass, among others), authenticate web tunnels and file transfers, and more.

kubesec - Secure Secret management for Kubernetes (with gpg, Google Cloud KMS and AWS KMS backends)

•    Go

Secure secret management for Kubernetes (with gpg, Google Cloud KMS and AWS KMS backends).The nice thing about this approach (compared to complete file encryption) is that git diff and git merge become so much more user-friendly (+ you can ascertain that specific entry is present even if you don't have the key to decrypt the secret).

vault - Vault - cross-platform GPG KV store for teams made easy

•    Go

Vault is a secure cross-platform KV store wrapped around GPG which makes team collaboraion extremely easy. You can define as many Vaults as needed and use them rightaway without changing any configuration at all.Download the correct binary for your distribution (clck images above) into your PATH and check that GPG installed.

A tool to sign and verify JSON objects programmatically from node.js.This software is licensed under the MIT License.

git-secure-tag - Secure git tag signing

•    Javascript

git uses SHA-1 hashes when signing tag. SHA-1 is generally deprecated and is not a collision-safe anymore (though, collisions are yet to come pre-image attack is yet to come).git-secure-tag runs cat-file recursively for each entry (sorted alphabetically), enters submodules (if present), and hashes file/directory names, file contents, and submodules (recursively again) into a resulting Git-EVTag-v0-SHA512: ... SHA512 digest.
