A git credential helper for using BitWarden as a backend for credential storage. It supports only credential retrieval. Passwords are matched based on a mapping defined in the config file.

• go 1.13+
• BitWarden CLI

# install to $GOPATH/bin. Defaults to ~/go/bin.
$ go get github.com/tudurom/bw-git-helper

First, you need to tell Git to use this credential helper:

$ git config --global credential.helper '!bw-git-helper $@'

If you want to match entries based not only on the host, but also on the path, set credential.useHttpPath to true:

$ git config --global credential.useHttpPath true

Create the file ~/.config/bw-git-helper/config.ini. Each section has a host pattern as its name and a single property named target that specified the BitWarden vault entry (either by UUID, or by a string to search for).

Example:

[github.com*]
target=GitHub

[*.fooo-bar.*]
target=5d80865a-dc01-4dc1-b376-7a00087d6214

If you enable useHttpPath, you can use it for example to write mappings for different accounts:

[github.com/user1/*]
target=GitHub user1

[github.com/user2/*]
target=GitHub user2

; GitHub catch-all
[github.com/*]
target=My GitHub

[gitlab.com/*]
target=GitLab

This helper asks the user for their password through the means of pinentry. You can choose the pinentry implementation by adding a special [config] section:

[config]
pinentry=pinentry-gnome3

If you don't want to have bw-git-helper handle your username, you can disable that functionality:

[config]
use_username=false

You can also use the -c flag to load the config file from an arbitrary path:

git config --global credential.helper 'bw-git-helper -c ~/some/config.ini $@'
