gnupg not found

I am trying to install rvm. But I don't have gnupg/gpg installed. So I tried to install it using brew:

brew install gnupg

But after it's installed (verified by brew list), I cannot use gnupg.

which gnupg yields:

gnupg not found

I have also tried using the direct binary path:

/usr/local/Cellar/gnupg/2.2.16_1 --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3 7D2BAF1CF37B13E2069D6956105BD0E739499BDB

In which case, I get the following error:

zsh: permission denied: /usr/local/Cellar/gnupg/2.2.16_1

Solution 1:

The command is gpg, not gnupg (gnupg is the package name)

$ brew install gnupg
...
...
$ which gpg
/usr/local/bin/gpg

$ gpg --version                                                   130
gpg (GnuPG) 2.2.16
...

To install RVM,

$ gpg --keyserver hkp://pool.sks-keyservers.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3 7D2BAF1CF37B13E2069D6956105BD0E739499BDB
