# GPG Configuration
|
||
|
|
|
||
|
|
Imports the public GPG key defined by the variable `KEYID` and then assigns it ultimate trust
|
||
|
|
|
||
|
|
## Overview
|
||
|
|
|
||
|
|
This script imports your publicly hosted GPG key using `pgp.mit.edu` as the key host. It then assigns it
|
||
|
|
the ultimate trust level. It also downloads and configures GPG to use the configuration defined in `.config.gpg`
|
||
|
|
in the `home/.chezmoidata.yaml` file.
