Our Verdict

Best for

Mac users who want native OpenPGP encryption with optional Apple Mail integration.

Skip if

You're on Windows/Linux or don't want to pay for the Mail encryption plugin.

What is GPG Suite?

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.

It has been maintained as free software since its introduction in 1997 and continues to receive regular releases and security updates.

It ships as part of most Linux distributions and is also distributed for Windows via the Gpg4win project.
