I hope everyone knows that storing secret values in an open form in Git repositories (even private ones) is strongly discouraged. There have been a couple of times when I’ve cleaned up such repositories. Of course, you have to rewrite the history and coordinate it with the team. The official documentation suggests using
git-filter-branch, but there is a faster way.
Roberto Tyley wrote a BFG app in Scala in 2012 that is 10-720 times faster than
git clone --mirror git://example.com/some-big-repo.git java -jar bfg.jar \ --strip-blobs-bigger-than 100M \ --replace-text banned.txt some-big-repo.git cd some-big-repo.git git reflog expire --expire=now --all && \ git gc --prune-now--aggressive git push --force
The application knows how to delete:
Before using it, make sure that all this already absent in the current version of the files.
