## Features
|
|
|
|
* Works on Linux, MacOS and Windows [virtual environments](https://help.github.com/en/articles/virtual-environments-for-github-actions#supported-virtual-environments-and-hardware-resources)
|
|
* Allow to seed the internal cache of `gpg-agent` with provided passphrase
|
|
* Purge imported GPG key, cache information and kill agent from runner
|
|
* (Git) Enable signing for Git commits, tags and pushes
|
|
* (Git) Configure and check committer info against GPG key
|
|
|
|
## Prerequisites
|
|
|
|
First, [generate a GPG key](https://docs.github.com/en/github/authenticating-to-github/generating-a-new-gpg-key) and
|
|
export the GPG private key as an ASCII armored version to your clipboard:
|
|
|
|
```shell
|
|
# macOS
|
|
gpg --armor --export-secret-key joe@foo.bar | pbcopy
|
|
|
|
# Ubuntu (assuming GNU base64)
|
|
gpg --armor --export-secret-key joe@foo.bar -w0 | xclip
|
|
|
|
# Arch
|
|
gpg --armor --export-secret-key joe@foo.bar | sed -z 's;\n;;g' | xclip -selection clipboard -i
|
|
|
|
# FreeBSD (assuming BSD base64)
|
|
gpg --armor --export-secret-key joe@foo.bar | xclip
|
|
```
|
|
|
|
Paste your clipboard as a [`secret`](https://help.github.com/en/actions/configuring-and-managing-workflows/creating-and-storing-encrypted-secrets) named `GPG_PRIVATE_KEY` for example. Create another secret with the `PASSPHRASE` if applicable.

## Keep up-to-date with GitHub Dependabot
|
|
|
|
Since [Dependabot](https://docs.github.com/en/github/administering-a-repository/keeping-your-actions-up-to-date-with-github-dependabot)
|
|
has [native GitHub Actions support](https://docs.github.com/en/github/administering-a-repository/configuration-options-for-dependency-updates#package-ecosystem),
|
|
to enable it on your GitHub repo all you need to do is add the `.github/dependabot.yml` file:
|
|
|
|
```yaml
|
|
version: 2
|
|
updates:
|
|
# Maintain dependencies for GitHub Actions
|
|
- package-ecosystem: "github-actions"
|
|
directory: "/"
|
|
schedule:
|
|
interval: "daily"
|
|
```
