Varys

Share your secrets publicly and securely. Use Varys to GPG encrypt a secret for multiple users, just check in their public key.

Usage

Set a repo up with a secret you want to share (in this case test_secret) and add this workflow file:

name: Varys
on:
  push:
    paths:
    - "test/publickeys/*"

jobs:
  varys:
    name: Varys
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v1
      - name: Run Varys
        uses: hfaulds/varys@master
        with:
          publicKeyDir: test/publickeys
          secret: ${{ secrets.test_secret }}
          output: test/secret
          githubToken: ${{ secrets.GITHUB_TOKEN }}

Create a key (for a further guide see https://help.github.com/en/github/authenticating-to-github/generating-a-new-gpg-key):

gpg --full-generate-key

Commit your key:

gpg --armor --export [email protected] > test/publickeys/example.gpg

The Action will now run (it may be advisable to only run this on master depending who has access to your repository).

Once the Action has finished it will commit an output file (in this case test/secret) which can be decrypted using your private key:

gpg --decrypt test/secret

Improvements

This should probably only run after a PR is merged (i.e. there is a change to a protected branch) and may want/need to create a PR instead of just pushing to master.
