Overview
Description

GPG Suite bundles the tools needed to use OpenPGP encryption on a Mac: GPG Keychain for creating and managing keys, GPG Services for encrypting, decrypting, and signing files from the Finder context menu, and MacGPG, a command-line engine based on GnuPG. Together they let Mac users encrypt files and communications using industry-standard OpenPGP cryptography. The core suite is free, and it also includes GPG Mail, which adds encryption and signing buttons directly into Apple Mail. GPG Mail offers a 30-day free trial, after which continued use requires a paid support plan (around EUR 23.80/year). GPG Suite is macOS-only and is actively updated, with beta builds already supporting the newest macOS releases.

Signal is a nonprofit messaging app focused on privacy, with end-to-end encryption for all messages and calls by default and minimal metadata collection. It is the recommended choice for private communication.
