![]() If you are on Mac, you can easily install it using brew install bfg. Sensitive strings, credentials, or even complete files containing sensitive data. BFG CleanerīFG cleaner is a great tool to help remove almost anything from git history. I will take the extra step of removing it from git history and force-push it. We both know git remembers everything that’s committed - the hardcoded secret, the commit which introduced AWS keys, and the commit that removed it. I don’t want to revoke it because a few other developers are using the same AWS credential for some other project(s). My colleague who’s been busy debugging some issues peeks into my code, adds a few comments to improve code quality, and gives a □ for my PR.īut wait, I notice that I have hardcoded AWS credentials in PR #2. The code that I was writing for the last few days finally works on the local system. ![]() I have been working through sprints, adding new and optimizing existing code based on product requirements. This blog post is for those taking the red pill, especially for repos on GitHub Enterprise Server (Self-Hosted)! The Story Don’t know where the secrets have been configured in prod/dev environments (just bad secrets management) and fear those envs going down because of revocation/rotation.Committed something like SSNs, details and email IDs of clients, etc that cannot be rotated. ![]() Getting back to the topic, if you have committed secrets into code and you can regenerate these secrets, take the easiest route and revoke (or rotate) it.įrom experience, I’ve seen folks occasionally take the red pill (removing from git history) if they: The Dilemma: revoke secrets or remove from git history If you add a new regex for a particular secret type in the future and you find that such secrets are hardcoded already, you will have to revoke/rotate it or maybe remove it from git history. Most (if not all) tools search for specific regexes or high entropy. Pre-commit hooks to detect secrets are not foolproof solution. Unless we have something configured (like pre-commit hooks) to detect secrets, we can’t be aware of everything we commit into git repositories every time. All that matters to you (most probably) before committing a piece of code is that the code works. Sensitive like AWS credentials, SaaS login credentials, prod DB passwords, or even a CSV file containing customers’ SSNs. Have you ever committed anything sensitive in a git repository? To remove the secret, you must de-reference/delete the GitHub PRs and trigger GitHub repo garbage collection to delete commits with secrets. The PRs save a read-only copy of the code modifications. To delete secrets from a git repository, modifying the history and force-pushing it might not be sufficient if you use the GitHub Pull Requests feature. I believed this until I found I was partially wrong - removing something from git history doesn’t remove them from git repository’s history. With help of BFG Cleaner and privileges to force push the modified history, it’s a piece of cake. If you’re using Warp as your terminal, you can use Warp’s AI Command Search feature to surface the various commands to check history discussed above.Removing secrets from git repo is straightforward. Use AI to recall these various git commit history commands By default, this tool keeps the record for 90 days and lets you return to old commits not referenced by any branches. Unlike git log, git reflog is a local recording of changes made and tracks commits across every branch. These commits may not show up when calling git log, but you may be able to recover it using git reflog. With Git, it's possible to lose a commit by accidentally using commands like git reset -hard or through Git's garbage collection which removes unreferenced objects from the repository. There may be instances when you use git log but the commit you are searching for is not showing up. ![]()
