  a GitHub token that enables publishing snapshots.

  -- Find the angular-builds:token in http://valentine
  +- Find the angular-builds:token in the internal pw database
  - Go inside the CircleCI default docker image so you use the same version of openssl as we will at runtime: `docker run --rm -it circleci/node:10.12`
  - echo "https://[token]:@github.com" > credentials
  - openssl aes-256-cbc -e -in credentials -out .circleci/github_token -k $KEY
