What's the best encrypted git credential helper for Linux?

This is what we have in git sources: https://github.com/git/git/tree/master/contrib/credential

So you can use gnome-keyring (deprecated), libsecret or gpg-encrypted .netrc.

libsecret could be used with any Linux distribution without GNOME, I believe.

git config --global credential.helper /usr/share/doc/git/contrib/credential/libsecret/git-credential-libsecret
