Generating a PGP Key

For this we’ll be using GnuPG, aka GPG, which is a common implementation of the PGP spec.

$ gpg --full-generate-key

As this will be your master key, make sure to pick RSA and RSA, 4096 bits, and does not expire for the generation options.

Once it is complete, it will print the details of it. Here’s what I got as an example.

pub   rsa4096 2021-03-21 [SC]
      95535225B55B5A9F39E29F5EDAB85EABB6014D3F
uid                      Meghan Denny <hello@nektro.net>
sub   rsa4096 2021-03-21 [E]

The 955352... part is the identifier for your new key and will be used in future commands.
