If your development master key is stored in the RAILSMASTERKEY environment variable. The encrypted credentials are saved on config/. Master.key is the key which is necessary to de-crypt encrypted credentials. Rails will be automatically adding it to.gitignore file for you. You can share master.key with your team but don’t check into shared repository. As documentation warns us: “Don’t lose this master key! Put it in a password manager your team can access. It contains the autogenerated key that allows to decrypt your credentials.
The file that should not be tracked by Git under any circumstances (and is already listed in.gitignore for new Rails 5.2 projects) is config/master.key. This file should NOT be pushed to a git repo or any server as it can be used to decrypt and someone can steal sensitive information. Without this file or if it is modified, Rails will not be able to read your credentials stored in. Master.key is a file containing your encryption key.
