GnuPG  with binary name gpg  is an application used for public key encryption using the OpenPGP protocol  but also verification of signatures  cryptographic signatures  that also can validate the publisher if used correctly   To some extend  you could say it s for OpenPGP what OpenSSL is for X 509 and TLS   Unlike most Linux distributions  which make heavy use of GnuPG for ensuring untampered software within their package repositories   Mac OS X does not bring GnuPG with the operating system  so you have to install it on your own   Possible sources are    Package manager Homebrew  brew install gnupg gnupg2 Package manager MacPorts  sudo port install gnupg gnupg2 Install from GPGTools  which also brings GUI applications and integration in Apple Mail

On my clean macOS 10 15 7  I needed to brew link gnupg  amp  amp  brew unlink gnupg first and then used Ashish s answer to use gpg instead of gpg2  I also had to chown a few directories  before the un link
