I would love a way to add just one private file to a public repo that can hold credentials.
I love making open source projects, but whenever I try to test that everything is working, I either have to put credentials in a private repo somewhere else or expose them to the world. This causes me headaches every time I return to a repo for a bug fix after some prolonged time. It would be nice to be able to save them in the repo without the security vulnerability of having them public to the world.
How does everyone handle this problem?
