一个很好的解决方案来安全地保存git凭证？

是的，正如我在使用Git凭证助手与gnome-keyring作为Sudo时出错。

libsecret实现 XDG秘密服务API 。

这是目前使用的官方图书馆。

更新Git 2.15.x / 2.16（Q1 2018），其中 libsecret 的凭证助手（位于 $ contrib / ）已被改进，以允许可能提示最终用户解锁当前被锁定的秘密（否则秘密可能不会被加载）。

请参阅提交9c109e9 （2017年11月3日）由 Dennis Kaarsemaker（ seveas ）。

credential-libsecret ：解锁锁定的秘密

秘密服务DBUS接口公开的凭证可能被锁定。

设置 SECRET_SEARCH_UNLOCK 标志将使秘密服务解锁这些秘密，可能会提示用户以获得凭据。
如果没有此标志，则秘密根本不会被加载。

I've been recently looking for a solution on how to securely save git credentials in CentOS 7.

I want to save credentials for multiple git repositories.

The solution that I come up with is to use gnome-keyring with any version of git. but I was experiencing some issues with it. and I found many posts saying it's not a good a solution in Redhat 7 or Centos 7. and It will be deprecated.

git config --global credential.helper /usr/share/doc/git/contrib/credential/gnome-keyring/git-credential-gnome-keyrin  

But this didn't work for me, an error when using git :

error communicating with gnome-keyring-daemon

then I upgraded git the last version 2.11+ to use libsecret which seems to be more easy to use.

I have done the same thing.

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

And this seems to work as expected. my Question is this is a good solution to securely save git credentials ? Do you know any other solution to save git credentials on a CentOS machine?

is this is a good solution to securely save git credentials ?

Yes, as I documented in "Error when using Git credential helper with gnome-keyring as Sudo".
libsecret implements XDG Secret Service API.

It is the current official library to use.

Update Git 2.15.x/2.16 (Q1 2018), where the credential helper for libsecret (in contrib/) has been improved to allow possibly prompting the end user to unlock secrets that are currently locked (otherwise the secrets may not be loaded).

See commit 9c109e9 (03 Nov 2017) by Dennis Kaarsemaker (seveas).

credential-libsecret: unlock locked secrets

Credentials exposed by the secret service DBUS interface may be locked.
Setting the SECRET_SEARCH_UNLOCK flag will make the secret service unlock these secrets, possibly prompting the user for credentials to do so.
Without this flag, the secret is simply not loaded.
