How to encrypt, sign and decrypt messages using GnuPG on macOS

[ghost]

Thanks for sharing your knowledge as well as your tutorials and videos. Even as a beginner, I was able to spoof my Mac address and hostname successfully. Moreover, I installed homebrew 3.3.1 and then ran the command brew install gnupg but encounter an error message before...

macbookpro@Brocks-MacBook-Pro ~ % brew install gnupg Updating Homebrew... ==> Auto-updated Homebrew! Updated 1 tap (homebrew/core). ==> Updated Formulae Updated 1 formula.

Error: Failed to link all completions, docs and manpages: Permission denied @ rb_file_s_symlink - (../../../Homebrew/completions/zsh/_brew, /usr/local/share/zsh/site-functions/_brew) Error: The following directories are not writable by your user: /usr/local/share/zsh /usr/local/share/zsh/site-functions

You should change the ownership of these directories to your user. sudo chown -R $(whoami) /usr/local/share/zsh /usr/local/share/zsh/site-functions

And make sure that your user has write permission. chmod u+w /usr/local/share/zsh /usr/local/share/zsh/site-functions macbookpro@Brocks-MacBook-Pro ~ %

PS: Maybe I am doing something wrong or ran into an edge case. Please Sun, What can I do? Would you be able to provide me with a script to run this successfully? Thank you very much!
