GPGTools is a suite of open source tools for encrypting, decrypting, and signing files, emails, and other data. It is based on the GNU Privacy Guard (GnuPG or GPG) encryption software. The GPGTools suite includes a graphical user interface (GUI) and command-line tools for encrypting and decrypting files, and for creating and verifying digital signatures. It also includes a plugin for Microsoft Outlook and Apple Mail, which allows users to digitally sign and encrypt their emails. GPGTools also provides a secure, cloud-based storage system for storing encrypted files and emails. GPGTools is designed to make it easy for users to protect their data and communications without needing to be an encryption expert. The software is available for macOS, Windows, and Linux.
