[neomutt-users] How to use cryptographically sign my email messages

[TJ Hayes]

How can I set up crypto keys to use with my emails sent from neomutt?

I did find https://neomutt.org/test-doc/howto/encryption and I can follow those instructions, but I don't really understand what I am doing. It says that I can "display the private keys via gpg ..." but I thought I didn't want to share my private key with anyone?
