Find out if your GitHub repository contains sensitive information such as password, secret key, confidential, etc.

GitHub is used by millions of users to host and share the codes. It’s fantastic, but sometimes you/developers/code owner can accidentally dump confidential information in public repository which can be a disaster.

There are many incidents where confidential data was leaked on GitHub. You can’t eliminate human error but can take action to reduce that.

How do you ensure your repository doesn’t contain a password or key?

Simple answer – don’t store.

But in reality, you can’t control other people behavior if working in a team.

Thanks to the following solution which helps you to find mistakes in your repository.
