Storing sensitive or secret information within a Git repository is never a good idea, at least as long as you do it unencrypted. Whoever has access to the Git repository, can view and change this sensitive data. Storing encrypted data within a Git repo has also the downside, that you need to decrypt it while you want to work with the data and you have to remember to reencrypt it, before pushing it back again. Here comes git-crypt into play. Git-crypt gives you a transparent method to de- and encrypt data during pulling and pushing from or to your Git repository.
