GPG Suite Nightly

GPG Suite Nightly is the nightly-build variant of GPG Suite for macOS. It brings together tools for working with OpenPGP keys and protecting email and files; it is distinct from the regular GPG Suite cask.

• GPG Keychain lets you create and manage keys, add email addresses to a key, and import keys from a key server. Key creation offers an advanced view for choosing key size, expiration, and algorithm.
• GPG Mail integrates with macOS Mail to encrypt and sign messages, and to decrypt or verify protected messages and attachments.
• GPG Services provides encryption, decryption, signing, and verification for text selections, files, and folders through the macOS Services context menu.
• MacGPG is the suite’s underlying encryption engine and can also be used from the command line.

Install with brew install --cask gpg-suite@nightly. The cask requires macOS. This nightly cask conflicts with gpg-suite, gpg-suite-no-mail, and gpg-suite-pinentry, so those casks cannot be installed alongside it. The vendor describes the suite’s capabilities generally; the nightly designation identifies this as a nightly build, not the regular cask.
