Trouble signing

[dvogeldev]

The README is a bit vague. I forked the repo, cloned it to local. cosign generate-key-pair > pushed changes to github. Added repo key to settings > security > actions with the title COSIGN_PRIVATE_KEY. It builds an image, but fails on SIGN CONTAINER IMAGE.

The TLDR debug msg:

====================================================
Run echo "***
654 cosign.key
Error: signing [ghcr.io/dvogeldev/boxkit@sha256:ccb6142c9fd622bcefba11242614588da900c335c0343b4ff12ef03aeb926f89]: getting signer: reading key: decrypt: encrypted: decryption failed

**What am I doing wrong?** 

A newb for sure when it comes to containers and cloud workflow. 
Thanks for all the hard work with UBlue-OS.

SOLUTION:

This issue was created by not using the declared variables from the github workflow.

env:
TAGS: ${{ steps.push.outputs.digest }}
COSIGN_EXPERIMENTAL: false
COSIGN_PRIVATE_KEY: ${{ secrets.SIGNING_SECRET }}

Using the cosign command cosign generate-key-pair github:myUser/myRepo with the following environment variables:

export GITHUB_TOKEN=ghp_xyz123
export CONSIGN_PASSWORD=pwd123

I was able to automatically add secrets to my github repo. I still needed to change a couple of workflow envirnoment variables.

env:
TAGS: ${{ steps.push.outputs.digest }}
COSIGN_EXPERIMENTAL: false
COSIGN_PASSWORD: ${{ secrets.COSIGN_PASSWORD }}
COSIGN_PRIVATE_KEY: ${{ secrets.COSIGN_PRIVATE_KEY }}

I was able to figure this out referencing Sign Your Container Images with Cosign Github Actions and Container Registry
