Getting Started with GpgFrontend

Welcome to GpgFrontend, the cross-platform, OpenPGP encryption tool designed for simplicity and security. This guide will walk you through the installation process tailored to your operating system, ensuring you can start securing your communications as quickly and efficiently as possible.

Before You Begin: Prerequisites

Note for Windows or macOS users who utilize Homebrew: You may skip this prerequisites section.

GpgFrontend leverages the robust functionalities of GnuPG for encryption, decryption, and key management. It is crucial to have GnuPG installed on your device to make full use of GpgFrontend. Starting from version 2.0, GnuPG operates on modular components for enhanced functionality, requiring proper integration with your system.

Be aware, due to GnuPG’s inability to function within an App Sandbox, GpgFrontend is not available through the Apple Store.

For Linux users, most contemporary distributions come with GnuPG 2.0 pre-installed. Check your GnuPG version with gpg --version in your terminal. It is advisable to upgrade to GnuPG version 2.2 or later for optimal performance and compatibility.
