Help you avoid to commit your sensitive keywords

git filter details, see https://git-scm.com/book/en/v2/Customizing-Git-Git-Attributes

1. copy keyfilter.py into your project
2. to avoid committed keyfilter.py, add it into .gitignore

1. Add .gitattributes in your workspace, and add content as below

configData.json    filter=keyfilter

2. Or edit .git/info/attributes if you don’t want the attributes file committed with your project

echo 'configData.json    filter=keyfilter' >> .git/info/attributes

1. Add by command and it will add in .git/config, which will not be committed with your project

git config filter.keyfilter.smudge "python keyfilter.py --smudge"
git config filter.keyfilter.clean "python keyfilter.py --clean"

2. Or edit .git/config, which will not be committed with your project

[filter "keyfilter"]
        smudge = python keyfilter.py --smudge
        clean = python keyfilter.py --clean

3. Or add .gitconfig as local, which will be committed with your project. and add content in last step

git config --local include.path ../.gitconfig

1. Avoid to use simple keywords, which may conflict with replace content, for example:

{
    "username": "user"
    "password": "pass"
}
