About:
Free-GPGMail is an open-source plugin that integrates GnuPG encryption capabilities directly into Apple's Mail application. It enables users to sign, encrypt, and decrypt emails using the OpenPGP standard without relying on proprietary software. This fork of the original GPGMail plugin ensures continued compatibility and privacy-focused email communication on modern macOS versions.

Key Features:

Seamless integration with Apple Mail for native encryption workflows
Support for OpenPGP standard including signing and encryption
Open-source alternative to proprietary GPG mail plugins
Compatible with GPG Suite backend for key management

Use Cases:

Securing sensitive email communications with end-to-end encryption
Digitally signing emails to verify authenticity and integrity
Maintaining privacy in email correspondence using open standards

Alternatives:

GPG Suite – Official GPG tools with mail plugin, but proprietary and requires paid license for full features
Thunderbird with Enigmail – Alternative email client with built-in encryption support, cross-platform but different UI
