GpgFrontend
A modern, cross-platform OpenPGP tool with a unique dual-engine core: switch
freely between the battle-tested GnuPG and a modern, memory-safe Rust
rPGP backend. It makes encryption, signing, and key management easier and
more trustworthy in everyday privacy workflows.
Key Features
- Easy: Encrypt and sign your texts, files and more in just a few clicks.
- Cross-platform: Native support for Windows, macOS and Linux.
- Profiles: Keep separate sets of keys and settings, and switch between them.
- Portable: Run from a USB drive, or carry a profile in one encrypted file.
- Dual-engine: Switch freely between the mature GnuPG and the Rust rPGP backend.
- Future-proof: Explore OpenPGP v6 (RFC 9580) and post-quantum algorithms.
- Memory-safe: Sensitive data is guarded in secure memory while in use.
- Privacy-focused: Everything runs locally, with no telemetry or tracking.

Release Channels
-
v2.2.x (Stable, recommended): The current stable series and the
recommended choice for daily use. It introduces the dual-engine core, adding
the Rust rPGP backend for OpenPGP v6 (RFC 9580) and post-quantum
algorithms alongside GnuPG, which remains the default and most
interoperable backend. rPGP-related features continue to evolve over time.
-
v2.1.x (Legacy): The previous GnuPG-only stable series. It remains in
maintenance mode, focusing on bug fixes and security updates, with no new
major features or breaking changes planned. Choose this if you need a pure
GnuPG build or are not ready to adopt the multi-engine 2.2 line.

Contributing Guide
For Developers
Although GpgFrontend's UI looks simple, its architecture is not trivial,
especially for developers unfamiliar with C++, Qt, asynchronous workflows, and
multithreading. An AI-assisted
Wiki is available based on
source-code analysis. It can be helpful for navigation and high-level
understanding, but it may not be fully accurate in all implementation details.
Please use it together with the source code rather than as a replacement for it.
For setting up the development environment, please refer to the Development
Environment Setup Guide.

Mission and Origins
GpgFrontend inherits the codebase from the discontinued but easy-to-use
gpg4usb. As described in my
blog post "The Past and Present of GpgFrontend: My Journey with an Open-Source
Encryption Tool", the project
began with a simple question:
> "What if everyone could have a small, reliable, and secure 'crypto machine'. A
> tool that makes encryption as tangible and trustworthy as turning a key in a
> lock?"
