Save passwords in OS keyring

[rugk]

This is really a low-priority idea, but IMHO it is a nice idea for a FLOSS project. Maybe something for contributors…

Currently you save the password in the config file of 0ad. It is hashed, that is good. However, it can be imroved by using a well-known mechanism for storing password, whcih (nearly) each OS has: Keyrings or Keychains.

So using well-proven/standard techniques you can store the password in the keyrings of KDE/Gnome or Max OS. All, of course, offer APIs for that, but they are likely very different. So maybe it is a long-term goal, but as 0ad is an open-source project I could imagine this being a tiny thing, which can set it apart from the competition, which likely do all crazy things with passwords instead of using the proper™ way… :rolleyes:

BTW, there are even ways to use this on Windows[1][2], but probably that is kind of difficult, so IMHO the focus should be on the Linux/MacOSD implementation if anybody is interested in this.

Using a third-party library which provides a unified cross-platform interface might probably be a good idea to reduce the effort of implementing that. ​https://github.com/hrantzsch/keychain/ might be an option for that.
