Remove sensitive data from diff on github

  • 772

I want to eliminate sensitive data that appears in the diff when commits are compared on github, for x reasons I put a sensitive data in a field, and after changing it and pushing it, this data continues to appear in the commit history as part of a change in a commit, how can I solve this problem, without deleting the commit?

    As it is a piece of text within a file and not a whole file, it is somewhat more complicated, but you can copy the content of the file and use: git filter-brancho BFG Repo-Cleaner

    Head over here for more information.

    Extensive information:

    You have to use BFG Repo-Cleaner as it is faster and has more options than git filter-branch:

    First you have to create a file and inside put the text you want to replace:

    $ echo "soy un dato sensible" > toReplace.txt

    Then using BFG you have to run this:

    $ git clone --mirror git://example.com/my-repo.git
$ java -jar bfg.jar --replace-text toReplace.txt  my-repo.git

$ cd my-repo.git

$ git reflog expire --expire=now --all && git gc --prune=now --aggressive
$ git push

    What will happen is that it will look for "I am sensitive data" and change it to * * * REMOVED * * *

    I insist: Read carefully the link to expand the information since it is a sensitive thing.
