Using secret api keys on travis-ci

I'd like to use travis-ci for one of my projects.

The project is an API wrapper, so many of the tests rely on the use of secret API keys. To test locally, I just store them as environment variables. What's a safe way to use those keys on Travis?

Solution 1:

Travis has a feature to encrypt environment variables ("Encrypting environment variables"). This can be used to protect your secret API keys. I've successfully used this for my Heroku API key.

All you have to do is install the travis gem, encrypt the string you want and add the encrypted string in your .travis.yml. The encryption is only valid for one repository. The travis command gets your public key for your repo and can then decrypt the string during the build.

gem install --user travis
travis encrypt MY_SECRET_ENV=super_secret -r my_username/my_repo

This gives you the following output:

Please add the following to your .travis.yml file:

  secure: "OrEeqU0z6GJdC6Sx/XI7AMiQ8NM9GwPpZkVDq6cBHcD6OlSppkSwm6JvopTR\newLDTdtbk/dxKurUzwTeRbplIEe9DiyVDCzEiJGfgfq7woh+GRo+q6+UIWLE\n3nowpI9AzXt7iBhoKhV9lJ1MROrnn4DnlKxAEUlHTDi4Wk8Ei/g="

Solution 2:

according to this in travis ci documentation it's said that :

If you have both the Heroku and Travis CI command line clients installed, you can get your key, encrypt it and add it to your .travis.yml by running the following command from your project directory:

travis encrypt $(heroku auth:token) --add deploy.api_key

refer to the following tutorial to install heroku client according to your OS
