Before proceeding, I suggest reading up on GPG if you are unfamiliar with it.
You can find more information about GPG on the [GnuPG official website](https://gnupg.org/){target="_blank"}.
You can utilize the public key here to verify software and binaries released by me.
You can also use the key to encrypt emails you send to me. In that case, I would also need your public key so I can encrypt the emails I send back to you.
The excellent [Email Self-Defense Guide by the Free Software Foundation](https://emailselfdefense.fsf.org/){target="_blank"} describes how this process works.
